Given h(x)=-5x-4 find h(3)

Answers

The value of the equation h(x) = -5x-4 is - 19 when h = (3).

What are equations?

An equation is a mathematical statement that contains the symbol "equal to" between two expressions with identical values.

As in 3x + 5 = 15, for example.

There are many different types of equations, including linear, quadratic, cubic, and others.

The three primary forms of linear equations are point-slope, standard, and slope-intercept.

So, the equation we have is:

h(x) = -5x-4

Now, solve the equation when h = (3)

h(x) = -5x-4

h(3) = -5(3) -4

h(3) = -15 - 4

h(3) = - 19


Therefore, the value of the equation h(x) = -5x-4 is - 19 when h = (3).

-2x + 13 = -7x + 28

Answers

Answer:

x=3

Step-by-step explanation:

step one: first, you want to make it so that the variable x is only on one side. to do this, you use inverse operations. this means adding 7x to both sides.

-2x+7x=5x    -7x+7x cancels itself out

the equation is now 5x+13=28

step two: next, you want to isolate the variable x. to do this you are going to use inverse operations yet again, this time subtracting 13 from both sides.

13-13=0       28-13=15

the equation is now 5x=15

step three: lastly, you want get x by itself without the 5 in front of it. using inverse operations for the last time, you are going to divide both sides by 5 because 5x means "5 times x" and division is the opposite of multiplication.

5x/5=x     15/5=3

the answer is now x=3

Answer:

x= 3.

Step-by-step explanation:

1. Write the equation.

[tex]-2x + 13 = -7x + 28[/tex]

2. Add "7x" to both sides of the equation.

[tex]-2x + 13 +7x= -7x + 28+7x\\ \\13+5x=28[/tex]

3. Subtract "13" from both sides of the equation.

[tex]-13+13+5x=28-13\\ \\5x=15[/tex]

4. Divide both sides by "5".

[tex]\frac{5x}{5}=\frac{15}{5} \\ \\x=\frac{15}{5}\\ \\x=3[/tex]

5. Verify.

If the result is correct, when we substitute the value of x in the original equation, it should return the same value on both sides of the equal (=) symbol. Let's test it!

[tex]-2(3 ) + 13 = -7(3) + 28\\ \\-6+13=-21+28\\ \\7=7[/tex]

That's correct! Therefore, the correct answer is x=3.

What is exponential growth?

An exponential function's curve is created by a pattern of data called exponential growth, which exhibits higher increases with time.

Consider a population of mice that increases exponentially every year by a factor of two, starting with 2 in the first year and increasing to 4 in the second, 8 in the third, 16 in the fourth, and so on. The population is rising by a factor of 2 per year in this example. If mice gave birth to four pups instead, you would then have 4, 16, 64, and 256.

Linear growth, which is additive, and geometric growth can be contrasted with exponential growth, which is multiplicative (which is raised to a power).

This equation represents exponential growth because the base is greater than 1, the function represents growth and  Whenever the base is less than 1, the function represents decay.

The base 1.06 is greater than 1, hence The equation represents exponential growth.

The formula for exponential growth:

use the mean value theorem to verify that at some time during the first 3 seconds of fall the instataneous velocity equals the average velocity

Answers

Verified that during the first 3 seconds of fall the instantaneous velocity equals the average velocity, the time is 1.5 seconds

The height of an object t seconds after it is dropped from a height of 300 meters is

s(t) = -4.9t^2 + 300

The average velocity of object during first 3 seconds

= s(3) - s(0) / 3 - 0

s(3) = -4.9 × (3)^2 + 300

= -44.1 + 300

= 255.9 meters

s(0) = -4.9(0)^2 + 300

s(0) = 300

The average velocity = (255.9 - 300) / 3 - 0

= -44.1 / 3

= -14.7 meter per second

To find  instantaneous velocity differentiate the function

= -9.8t

The instantaneous velocity = The average velocity

-9.8t = -14.7

t = -14.7/-9.8

t = 1.5 seconds

If 24000 bricks of the same shape and size are required to build a wall of dimension 15m*6m*20m find the volume of each brick

Answers

The volume of each brick is 0.75m³

What is volume?

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object. It is measured in cubic units.

A brick has a cuboidal shape. This means the volume of a cuboid is given as:

V = l×b×h

This means volume = area × height

The volume of the whole wall is calculated as:

15× 6× 20 = 18000m³

Since there are 24000 bricks needed for the wall. The volume of each brick is therefore calculated as:

V =18000/24000

= 0.75m³

Therefore the volume of each brick is 0.75m³

b = 327.41

∠C = 53°

Question 6

a = 34.11

b = 73.987

∠C = 53°

What is the law of cosines?

The law of cosines is a relationship between two sides (b and c) and the included angle, (∠A) and the third side (a) of the triangle.

Mathematically; a² = b² + c² - 2·b·c·cos(A)

Question 1

The dimensions of the triangle ΔABC are;

a = 3.0, b = 4.0, ∠C = 54°

The law of cosines indicates that we get;

c² = b² + a² - 2·b·a·cos(∠C)

Therefore;

c² = 3.0² + 4.0² - 2 × 3.0 × 4.0 × cos(54°) ≈ 10.893

c ≈ √(10.893) ≈ 3.3

The law of sines indicates that we get;

sin(54°)/3.3 = sin(∠A)/3.0

∠A = arcsine(3 × sin(54°)/3.3) ≈ 47.35°∠B = 180° - 54° - 47.35° ≈ 78.65°

Question 2

b = 69, c = 35, ∠A = 72°

a² = 69² + 35² - 2 × 69 × 35 × cos(72°) ≈ 4493.45

a ≈ √(4493.45) ≈ 67.03

The law of sines indicates that we get;

sin(72°)/67.03 = sin(∠B)/69

∠B = arcsine(69 × sin(72°)/67.03) ≈ 78·24°

∠B ≈ 78.24°

∠C = 180° - 72° - 78.24° ≈ 29.76°

∠C  ≈ 29.76°

Question 3

a = 28, b = 39, c = 29

a² = b² + c² - 2·b·c·cos(A)

cos(A) = (a² - (b² + c²)) ÷ (2·b·c)

Therefore; cos(A) = (28² - (39² + 29²)) ÷ (-2 × 39 × 29) ≈ 0.6976

∠A = arccos(0.6976) ≈ 45.77°

sin(45.77)/28 = sin(B)/39

sin(B) = 39 × sin(45.77)/28 ≈ 0.998

∠B = arcsine(0.998) ≈ 86.417°∠C = 180° - 45.77° - 86.417° = 47.813°

Question 4

a = 13, b = 17, c = 22

cos(A) = (13² - (17² + 22²)) ÷ (-2 × 17 × 22) ≈ 0.807

∠A ≈ arccos(0.807) ≈ 36.15°

sin(36.15)°/13 = sin(∠B)/17

sin(∠B) = 17 × sin(36.15)°/13

∠B =50.48°           ∠C = 180° - 36.15° - 50.48° ≈ 93.37°

Question 5

The parameters of the triangle are; ∠A = 50°, ∠B = 77°, c = 270

Please find attached the sketch of the triangle in the correct option created with MS Word

∠C = 180° - 50° - 77° = 53°

a/sin(50°) = 270/sin(53°)

a = sin(50°) × 270/sin(53°) ≈ 258.98

a = 258.98

b = sin(77°) × 270/sin(53°) ≈ 329.41

b ≈ 329.41

Question 6

The parameters of the triangle are;

∠A = 27°, ∠B = 100°, c = 60

Please find attached the drawing of the correct triangle

∠C = 180° - 27° - 100° = 53°

Answers

A)

A manufacturer of banana chips would like to know whether its bag-filling machine works correctly at the 414-gram setting.

So, Null hypothesis: [tex]H_{0}[/tex] : μ < 414

It is believed that the machine is underfilling the bags.

So, Alternate hypothesis: [tex]H_{1}[/tex] : μ < 414

Given,

n= 8

Population standard deviation (б) = 18

x= 407

We will use the t-test since n > 8 and we are given the population standard deviation.

t=x-μ / (б/[tex]\sqrt{n-1}[/tex])

t= [tex]\frac{407-414}{\frac{18}{\sqrt{7} } }[/tex]

t= -1.028

Use the t table to find p value

p-value = 12.706

Level of significance α = 0.025

p-value>α

It is a two-tailed test.

So, we fail to reject the null hypothesis.

So, its bag-filling machine works correctly at the 414-gram setting.

B)

Let μ be the population mean amount of ozone in the upper atmosphere.

As per the given, we have

[tex]H_{0}[/tex]    : μ = 4.8

[tex]H_{1}[/tex] : μ ≠ 4.8

Sample size: n= 26

Sample mean = 4.6

Standard deviation = 1.2

Since population standard deviation is now given, so we use a t-test.

t= [tex]\frac{4.6-4.8}{\frac{1.2}{\sqrt{25} } }[/tex]

t= -0.2/0.24

t= -0.833

It is a two-tailed test.

use proof by contraposition to show that for intergers m and n that if mn is even then m is even and n is even

Answers

In order for m n to be even, m must be even or n must be an even number.

Let's understood what is integers.

In mathematics, a collection of both positive and negative integers is referred to as an integer. Like whole numbers, integers do not contain a fractional portion. The definition of an integer is that a number that can be either positive, negative, or zero but is not a fraction. On integers, we can carry out all arithmetic operations, including addition, subtraction, multiplication, and division. Examples of integers include 1, 2, 5, 8, -9, and -12. "Z" stands for an integer.

Proof by contraposition:

Suppose that the statement m“ is even or is even n” is not true. Consequently, m and n should both be odd. Let's check to determine if the sum of two odd numbers is even or odd: Let m and n be equal to 2a+1 and 2b+1 respectively, then their product is:

(2a+1) (2b+1) = 4ab+2a+2b+1 =2(2ab+a+b) +1

This shows that the expression 2(2ab+a+b) +1 is of the form 2n+1, thus the product is odd. If the product of odd numbers is odd, then m n is not true to be even. Therefore, in order for m n to be even, m must be even, or n must be an even number.

The lines that carry the rectangle onto itself are x = 0 and y = 1

How to determine the lines that carry the rectangle onto itself?

The graph that completes the question is added as an attachment

From the question, we have the following parameters that can be used in our computation:

The rectangular graph

The coordinates of one end of the graph are

(-3, 3) and (-3, -1)

Next, we calculate the midpoint of these ends

So, we have

Midpoint = 1/2(x₁ + x₂, y₁ + y₂)

Substitute the known values in the above equation, so, we have the following representation

Midpoint = 1/2(-3 + 3, -1 + 3)

Evaluate the like terms

Midpoint = 1/2(0, 2)

So, we have

Midpoint = (0, 1)

So, we have

x = 0 and y = 1

Hence, the reflection lines are x = 0 and y = 1

The equation of given graph is y = 2x + 6.

What is equation of line?

The formula for a straight line is y = mx + c where c is the height at which the line intersects the y-axis, also known as the y-intercept, and m is the gradient.

Given:

The graph of the line is given.

From graph we have to find the equation of line.

Let the graph passes through the points (0, 6) and (2, 10).

From these two points to find the slope.

Slope = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Here, [tex](x_1, y_1) = (0, 6), (x_2, y_2) = (2, 10)[/tex]

⇒ Slope = m = [tex]\frac{10-6}{2-0}= \frac{4}{2} = 2[/tex]

So, the slope is 2.

Now to find the equation of line.

Consider, the point - slope form of the line,

[tex]y-y_1=m(x-x_1)[/tex]

Plug [tex]m = 2, (x_1, y_1) = (0, 6)[/tex]

[tex]y-6=2(x-0)\\y-6=2x\\y=2x+6[/tex]

Answers

To determine the end behavior of a function, we substitute high values in for x, and we can even substitute in infinity. However, infinity is not a defined number, but it is a concept, so it will give us an idea about the “tails” of the function.

Let’s use logic here:

We know we have a cubic function with a coefficient of 4, so if we input any positive value in for x, we will get a y value that is a large positive value.

For example, let’s plug 1,000,000 in for x:

f(1,000,000)=4(1,000,000)^3

f(1,000,000)=4e+18

This is an extremely high positive value.

Therefore, because we have a positive coefficient and a power of 3, when we input a positive value in for x, we receive a large positive y-value. This means that as x——> ♾️, y——>♾️

Now, let’s look at negative values:

We have already noted that we have a cubic parent function. Remember that a negative times a negative is a positive times a negative is a negative. This is because if we input a negative value in for x, it will be a large negative value. Even with a coefficient of 4, a positive times a negative is a negative. Let’s see an example:

f(♾️)=4(-♾️)^3

f(♾️)=4(-♾️)(-♾️)(-♾️)

f(-♾️)=4(-♾️)^2(-♾️)

f(-♾️)=4(-♾️)^3

So, we end up with negative infinity times four, which is an even larger negative value.

Therefore, x——>-♾️, y——>-♾️

The smallest possible value of f ( t ) = 9 based on the values of p , q , r , s.

Given :

Let f ( x ) be a polynomial with integer coefficients. Suppose there are four distinct integers p , q , r , s such that f ( p ) = f ( q ) = f ( r ) =f ( s ) = 5. If t is an integer and f ( t ) > 5,

Let g(x) = f(x) − 5.

g(x) = (x−p)(x−q)(x−r)(x−s)h(x)

The condition f(t) > 5 translates to g(t) > 0.

Since p,q,r,s,t are distinct integers, the smallest possible positive value of (t−p)(t−q)(t−r)(t−s) is 4 :

the four numbers in the parentheses are all distinct integers ≠ 0, so the smallest value we can get from the product (−2)⋅(−1)⋅1⋅2. }

The smallest possible positive value of h(t) is 1, since we must have g(t)≠0.

Thus the smallest possible value of g(t) is 4, and therefore the smallest possible value of f(t) is 9, and it is achieved for t=2 if we have
