The solution to the polynomial equation 8x⁴ - 32x² = 0 by factoring are x = 0 or x = -2 or x = 2
Using factoring to solve the polynomial equationTo solve the equation 8x⁴ - 32x² = 0 by factoring, we can factor out the greatest common factor of the terms:
8x²(x² - 4) = 0
Now we can use the difference of squares identity to factor the quadratic expression:
8x²(x + 2)(x - 2) = 0
Using the zero product property, we know that the product of two factors is zero if and only if at least one of the factors is zero.
Therefore, we can set each factor equal to zero and solve for x:
8x² = 0 or x + 2 = 0 or x - 2 = 0
Solving for x, we get:
x = 0 or x = -2 or x = 2
So the solution set for the equation is {0, -2, 2}.
To check the solution, we can substitute each value into the original equation and verify that it equals zero.

For which pair of functions is the exponential consistently growing at a faster rate than the quadratic over the interval 0 ≤ x ≤ 5?
One pair of functions that satisfies the given condition is:
Exponential function: [tex]f(x) = 1.46^x,[/tex] Quadratic function: [tex]g(x) = x^2[/tex]
What is expression ?In mathematics, an expression is a combination of numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division. Expressions can also include functions, brackets, and other symbols.
According to the given information:Let's consider the two functions:
Exponential function: [tex]f(x) = a^x, where a > 1[/tex]
Quadratic function: [tex]g(x) = x^2[/tex]
We want to find the pair of functions for which the exponential is consistently growing at a faster rate than the quadratic over the interval 0 ≤ x ≤ 5.
To determine this, we can compare the growth rates of the two functions by looking at their derivatives.
The derivative of the exponential function is:[tex]f'(x) = a^x * ln(a)[/tex]
The derivative of the quadratic function is: [tex]g'(x) = 2x[/tex]
To compare the growth rates of the two functions, we need to compare their derivatives. We want to find the value of x for which the exponential function is growing faster than the quadratic function, i.e., where f'(x) > [tex]g'(x).\\f'(x) > g'(x)\\a^x * ln(a) > 2x[/tex]
Now, we can solve for x:
[tex]a^x * ln(a) > 2xln(a)/2 * a^x > x[/tex]
Since we want to find the pair of functions for which the exponential is consistently growing at a faster rate than the quadratic over the interval 0 ≤ x ≤ 5, we need to find a value of a such that the inequality ln(a)/2 * [tex]a^5 > 5[/tex] is true for all values of a > 1.
We can use a graphing calculator or a numerical solver to find the value of a that satisfies this inequality. One possible solution is a ≈ 1.46.
Therefore, one pair of functions that satisfies the given condition is:
Exponential function: [tex]f(x) = 1.46^x,[/tex] Quadratic function: [tex]g(x) = x^2[/tex]

let be the space spanned by the two functions and . find the matrix of the linear transformation from into itself with respect to the basis .
When space is spanned by the two functions of linear transformation from into itself with respect to the basis we need to apply T to each basis vector vi to get the column vectors T(vi) = [T(vi)]B.
where [T(vi)]B is the coordinate vector of T(vi) with respect to the basis B. Arrange the column vectors [T(v1)]B, [T(v2)]B, ..., [T(vn)]B into a matrix. This matrix is the matrix of T with respect to the basis B.

To check if an ordered pair is a solution to a system of equations, we substitute the values of x and y into both equations and see if both equations are satisfied.
Let's check each ordered pair one by one:
(1, -7):
9x + 2y = -5 becomes 9(1) + 2(-7) = -5, which is false.
2x - 3y = -8 becomes 2(1) - 3(-7) = -8, which is true.
Therefore, (1, -7) is not a solution to the system of equations.
(0, -4):
9x + 2y = -5 becomes 9(0) + 2(-4) = -8, which is false.
2x - 3y = -8 becomes 2(0) - 3(-4) = 12, which is false.
Therefore, (0, -4) is not a solution to the system of equations.
(5, 6):
9x + 2y = -5 becomes 9(5) + 2(6) = 41, which is false.
2x - 3y = -8 becomes 2(5) - 3(6) = -8, which is true.
Therefore, (5, 6) is not a solution to the system of equations.
(-1, 2):
9x + 2y = -5 becomes 9(-1) + 2(2) = -11, which is false.
2x - 3y = -8 becomes 2(-1) - 3(2) = -8, which is true.
Therefore, (-1, 2) is not a solution to the system of equations.
Therefore, the answer is "No" for all the ordered pairs given in the problem.

A binomial probability experiment is conducted with the given parameters. Compute the probability of x successes in the
n independent trials of the experiment.
n=9, p=0.4, x$3
The probability of x ≤ 3 successes is
. (Round to four decimal places as needed.)
The probability of x successes in n independent trials of the experiment is given by the Binomial probability formula, where n is the total number of trials and p is the probability of success in each trial.
Since n = 9 and p = 0.4, we can calculate the probability of x ≤ 3 successes as follows:
P(X ≤ 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)
= (9C0)(0.4)^0(0.6)^9 + (9C1)(0.4)^1(0.6)^8 + (9C2)(0.4)^2(0.6)^7 + (9C3)(0.4)^3(0.6)^6
= 0.17496 + 0.41472 + 0.36608 + 0.04320
= 0.99976
Therefore, the probability of x ≤ 3 successes is 0.99976.

Answer:
(a) y = 0.80x + 50
(b) Plugging x = 5 into the equation from part (a), we get y = 0.80(5) + 50 = 54, so the ordered pair associated with x = 5 is (5, 54). This means that if the car is driven for 5 miles, the total charge to the renter is $54.
(c) Let y be the total charge and solve for x:
y = 0.80x + 50
187.60 = 0.80x + 50
137.60 = 0.80x
x ≈ 172
Therefore, the car must have been driven approximately 172 miles
Answer:
(a) y = 0.8x + 50
(b) D. The ordered pair associated with the equation x = 5 is (5, 54) and it means that the charge for driving the car for 5 miles is $54.
(c) If the renter paid $187.60, the car must have been driven for 172 miles.
Step-by-step explanation:
Part (a)In the given problem, we are told that the rental car costs a flat fee of $50 plus an additional charge of $0.80 per mile driven.
Let x be the number of miles driven.
Let y be the total charge to the renter (in dollars).
We know that the total charge y will depend on the number of miles driven x, and we can express this relationship using a linear equation in the form y = mx + b, where m is the slope of the line and b is the y-intercept (the value of y when x = 0).
In this case, we know that the cost per mile is $0.80 so the slope of the line is m = 0.8, and the flat fee is $50 so the y-intercept is b = 50.
Substitute these values into the equation to get:
[tex]y = 0.8x + 50[/tex]
[tex]\hrulefill[/tex]
Part (b)To find the ordered pair associated with x = 5, substitute x = 5 into the equation:
[tex]\begin{aligned}x=5\implies y &= 0.8(5) + 50\\&=4+54\\&=54\end{aligned}[/tex]
The ordered pair associated with the equation x = 5 is (5, 54) and it means that the charge for driving the car for 5 miles is $54.
[tex]\hrulefill[/tex]
Part (c)To find how many miles the car was driven if the renter paid $187.60, set y = 187.60 and solve for x:
[tex]\begin{aligned}\implies 0.8x + 50&=187.60\\0.8x + 50-50&=187.60-50\\0.8x&=137.60\\\dfrac{0.8x}{0.8}&=\dfrac{137.60}{0.8}\\x &= 172\end{aligned}[/tex]
Therefore, if the renter paid $187.60, the car must have been driven for 172 miles.
Find the maximum/minimum value of the quadratic function q² + 22q = y - 85 by
completing the square method.
O-36
O-48
C
-24
-64
Step-by-step explanation:
To find the maximum/minimum value of the quadratic function q² + 22q = y - 85, we can complete the square as follows:
q² + 22q = y - 85
q² + 22q + 121 = y - 85 + 121 (adding (22/2)² = 121 to both sides)
(q + 11)² = y + 36
Now, we have a square of a binomial on the left side, which means the minimum value of the quadratic function is y + 36, and it occurs when (q + 11) = 0. Thus, the minimum value is:
y + 36 = 36 - 85 = -49
Similarly, the maximum value of the quadratic function occurs when (q + 11) = 0, but this time the value of y will be as large as possible. The largest possible value of y occurs when STU is a permutation of the digits 9, 8, and 7 (since PQR must be 4, 0, and 3 in some order). Thus, the maximum value is:
y + 36 = 9 + 8 + 7 - 85 + 36 = -25
Therefore, the options are incorrect and the correct answers are:
Minimum value: -49
Maximum value: -25
Determine the length of HK
Step-by-step explanation:
that height splits GK (32) into 2 parts :
8 and 32-8 = 24
then we use the geometric mean theorem for right-angled triangles
height = sqrt(p×q)
with p and q being the parts of the Hypotenuse.
so,
height = sqrt(8×24) = sqrt(192)
and now we can use Pythagoras
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90° angle), a and b are the legs,
to get HK.
HK² = height² + 24² = 192 + 576 = 768
HK = sqrt(768)

Define the term graph?The visual representation of mathematical functions or data points on a Cartesian coordinate system is an x-y axis graphic. The vertical or dependent variable is represented by the y-axis, while the horizontal or independent variable is represented by the x-axis. The difference between the change in output values and the change in input values is known as the average rate of change of a function over a period.
Let's assume that the function is denoted by f(x). Then, the average rate of change on the interval (a, b) can be calculated as
average rate of change = (f(b) - f(a)) / (b - a)
Using this formula, we can calculate the average rate of change on the given intervals as follows:

Find the inverse of the function
Answer:
g(y) = √(3/2 y)
Step-by-step explanation:
To find the inverse of a function, we need to solve for x in terms of y and interchange x and y. That is, we need to write the given function f(x) = 2/3x^2 in the form y = 2/3x^2 and then solve for x in terms of y.y = 2/3x^2
Multiplying both sides by 3/2, we get:
3/2 y = x^2
Taking the square root of both sides, we get:x = ± √(3/2 y)
Note that we have two possible values of x for each value of y, because the square root can be either positive or negative. However, for a function to have an inverse, it must pass the horizontal line test, which means that each value of y can only correspond to one value of x.Therefore, we need to restrict the domain of the original function to ensure that it is one-to-one. The simplest way to do this is to take the range of the function and use it as the domain of the inverse function.The range of f(x) = 2/3x^2 is all non-negative real numbers, or [0, ∞). Therefore, we can define the inverse function g(y) as:
g(y) = ± √(3/2 y)
where we choose the positive square root to ensure that the function is one-to-one.Thus, the inverse of the function f(x) = 2/3x^2 is:
g(y) = √(3/2 y)
with domain [0, ∞).

b. cos A = 15/17
c. tan A = 8/15
d. tan B = 8/15
What is trigonometric ratio?
Triangle side length ratios are known as trigonometric ratios. In trigonometry, these ratios show how the ratio of a right triangle's sides to each angle. Sine, cosine, and tangent ratios are the three fundamental trigonometric ratios.
For a right-angled triangle ABC, the hypotenuse AB is given as 17.
The base CB is given as 15 and the perpendicular AC is given as 8.
The angle C is given to be 90°.
Using the given values of the sides of the right triangle ABC, we can calculate the trigonometric ratios as follows -
a. sin A = opposite/hypotenuse = AC/AB = 8/17 (reduced fraction)
b. cos A = adjacent/hypotenuse = CB/AB = 15/17 (reduced fraction)
c. tan A = opposite/adjacent = AC/CB = 8/15 (reduced fraction)
d. tan B = opposite/adjacent = AC/CB = 8/15 (reduced fraction)
Note that since angle C is 90°, angles A and B are acute angles, so their tangent ratios are equal to each other.
Therefore, the ratios expressed as reduced fractions are -
a. sin A = 8/17
b. cos A = 15/17
c. tan A = 8/15
d. tan B = 8/15

Answers of angle degrees of p and q
q = 79
p = 101
Explanation
Each angle given has an adjacent angle creating a straight angle of 180 degrees.
First I found the missing adjacent angle degree - see attachment.
We know four of the five interior angle degrees are 85, 136, 138, 102.
Since we know the sum of angles in a pentagon = 540°, we can subtract the known angles from 540 to find “q”
540 - 85 - 136 - 138 - 102 = 79 angle q
To find “p” we know p and q create a straight angle of 180 degrees. We can subtract to find p.
180 - 79 = 101 angle p.

in the right triangle what is the value of X? 30 24 X
Answer:
x = 21
Step-by-step explanation:
Given the angle measurements of two angles, we can deduce that this is a 30-60-90 triangle. The formula for side lengths of this type of triangle is given by s → s√3 → 2s with s being the shortest side (the side opposite the 30° angle).
We are looking for the side length represented by s[tex]\sqrt{3}[/tex]. We can see that the hypotenuse is represented by 2s, so...
2s = 24
s = 12
The side length of the shortest side is 12. Therefore, we can say that
x = s [tex]\sqrt{3}[/tex]
x = 12 * [tex]\sqrt{3}[/tex]
x = 20.785
The question asks for our answer to the nearest whole number, so
x = 21

Therefore, the slope of the line that passes through (-2, 8) and (4, 6) is -1/3.
What is the slope?
In mathematics, the slope is a measure of the steepness of a line.
The solution provided involves three steps to find the slope of the line that passes through two points: (-2, 8) and (4, 6).
Step 1 involves finding the change in y-coordinates, which is the difference between the y-coordinate of the second point and the y-coordinate of the first point. In this case, the second point has a y-coordinate of 6 and the first point has a y-coordinate of 8.
Therefore, the change in y-coordinates is 6 - 8 = -2.
Step 2 involves finding the change in x-coordinates, which is the difference between the x-coordinate of the second point and the x-coordinate of the first point. In this case, the second point has an x-coordinate of 4 and the first point has an x-coordinate of -2.
Therefore, the change in x-coordinates is 4 - (-2) = 6.
Step 3 involves dividing the change in y-coordinates by the change in x-coordinates to find the slope of the line. In this case, the change in y-coordinates is -2 and the change in x-coordinates is 6, so the slope is -2/6 or -1/3.
Since all the steps are correct and properly executed, there is no error.
Therefore, the slope of the line that passes through (-2, 8) and (4, 6) is -1/3.

Step 1 Find the assessed value. Step 2 Express the tax rate as a decimal. Step 3 Find the real estate tax
The real estate tax on Brianna Wallen's home is $37,934.83.
What is property tax?Property owners, including homeowners, are subject to a tax based on the assessed value of their properties. It is often collected by local governments and used to pay for amenities like public transportation, roads, and security.
The assessed value of the property and the tax rate are used to determine the amount of property tax due. The assessed value of a property is its worth as established by a government assessor and may be based on a number of variables, including recent sales prices of nearby properties, the price to replace the property, and the property's condition.
The tax is calculated using the given formula:
Tax = (Assessment Rate x Market Value) x (Tax Rate / 1000)
Substituting the given values we have:
Tax = (0.29 x $438,300) x (81.16 / 1000)
Tax = $37,934.83
