What is the solution to the equation 1 over the square root of 8 = 4^(m + 2)? A) m = − 15 over 4 B) m = − 11 over 4 C) m = 5 over 4 D) m = 9 over 4
Answer:
B) m = -11/4
Step-by-step explanation:
What is the solution to the equation 1/sqrt(8) = 4^(m+2)
1 over the square root of 8 = 4^(m + 2)?
A) m = − 15 / 4
B) m = − 11 / 4
C) m = 5 / 4
D) m = 9 / 4
1/sqrt(8) = 4^(m+2) apply law of exponents
1/2^(3/2) = (2^2)^(2m+4)
2^(-3/2) = (2)^(2m+4)
-3/2 = 2m+4
2m = -11/2
m = -11/4
Shawn wanted to model the number 13,450 using 13,450 using base-ten blocks how many large cubes, flats, and longs does he need to model the number
Answer:
13 cubes, 4 flats, 5 longs
Step-by-step explanation:
Base-ten is basically just analyzing the place values of each number in the given value.
A cube represents 1,000, a flat represents 100, and a long represents 10.
Looking at the number 13,450, we can see that there are 13 thousands in this (13,000). This means that we will need 13 cubes.
We can also see that there are 4 hundreds in this (400), meaning we need 4 flats.
Also, there are 5 tens in this (50), so we need 5 longs.
Hope this helped!
The table shows the relationship between the cost of renting a car from the Wrecko Car Rental Company and the number of days for the rental. Draw a scatter plot and find an equation for the line of best fit. Use the equation to determine the cost of renting a car for 20 days. Days Cost 1 $44 2 $67 3 $90 4 $113 7 $182 10 $251
Answer:
The cost of renting the car for 20 days is $481
Step-by-step explanation:
The table of values can be formed as follows;
Day, Cost
1, $44
2, $67
3, $90
4, $113
7, $182
10, $251
From the given values and the scatter plot, there is a straight line relationship between the cost and the number of days of rental of a car.
The line of best fit is therefore a straight line and from the constant increase in cost ($23) for each extra day of rental, it is possible to find the slope, m, of the data as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
(x₁, y,) and (x₂, y₂) can be taken as (1, $44) and (3, $90) respectively to give;
[tex]Slope, \, m =\dfrac{90-44}{3-1} = \dfrac{46}{2} = 23 \ as \ stated \ above[/tex]
The equation in slope and intercept form is therefore, y - 44 = 23×(x - 1), which gives;
y - 44 = 23·x - 23
y = 23·x - 23 + 44 = 23·x + 21
The cost of renting the car for 20 days is then;
10×23 + 21 = $481
The cost of renting the car for 20 days = $481.

p and v
Step-by-step explanation:
Answer:
a. 1/32 then 1/64
b. P then V
Step-by-step explanation:
A is multiplied by 2 every time.
While b is doubled every time as well.
For which function is the ordered pair (4, 12) not a solution? y = 3 x y = 16 - x y = x + 8 y = 8 - x
if an ordered pair is a solution, it should satisfy the equation.
see the first option
[tex]y=3x[/tex] , if you put $x=4$ and $y=12$
you'll get $12=12$ which is true.
now the last option, $y=8-x$ put $x=4$ and $y=12$
$12=8-4\implies 12\ne4$ thus it is not a solution.
So option 4 is correct
Answer:

When sketching a normal curve, what
value represents one standard deviation
to the right of the mean for the data set?
56, 54, 45, 52, and 48.
Answer:
The value representing one standard deviation to the right of the mean is 55.
Step-by-step explanation:
The provided data set is:
S = {56, 54, 45, 52, and 48}
Compute the mean and standard deviation as follows:
[tex]\mu=\frac{1}{n}\sum X=\frac{1}{5}\times [56+54+45+52+48]=51\\\\\sigma=\sqrt{\frac{1}{n}\sum (X-\mu)^{2}}=\sqrt{\frac{1}{5}\cdot {(56-51)^{2}+...+(48-51)^{2}}}=\sqrt{\frac{1}{5}\times 80}=4[/tex]
Compute the value representing one standard deviation to the right of the mean as follows:
[tex]X=\mu+1\cdot \sigma[/tex]
[tex]=51+(1\times 4)\\=51+4\\=55[/tex]
Thus, the value representing one standard deviation to the right of the mean is 55.
what is the diamater of a circle
the area of a circle is 144π m^2
Answer:
24 meters
Step-by-step explanation:
The area of a circle can be found using the following formula.
[tex]a=\pi r^2[/tex]
We know that the area is 144pi m^2.
[tex]a= 144\pi m^2[/tex]
Substitute 144pi m^2 in for a.
[tex]144\pi m^2= \pi r^2[/tex]
We want to find the diameter. First, we must find the radius. We have to get the variable, r, by itself.
Divide both sides of the equation by pi.
[tex]144\pi m^2/ \pi = \pi r^2 / \pi[/tex]
[tex]144\pi m^2/ \pi = r^2[/tex]
[tex]144 m^2= r^2[/tex]
The variable, r , is being squared. The inverse of a square is the square root. Take the square root of both sides of the equation.
[tex]\sqrt{144 m^2} =\sqrt{r^2}[/tex]
[tex]\sqrt{144 m^2} =r[/tex]
[tex]12 m= r[/tex]
The radius of the circle is 12 meters, but the question asks for diameter. The diameter is twice the radius.
[tex]d= r*2[/tex]
The radius is 12 m.
[tex]d= 12 m*2[/tex]
Multiply
[tex]d= 24 m[/tex]
The diameter of the circle is 24 meters.
All points of the step function f(x) are graphed
What is the domain of f(x)?

O {x|2
Is it true or false that this is the graph of f(x) = 3^x?
Answer: False, this is not the graph of f(x) = 3^x
=====================================================
Explanation:
Plug in x = 0 to get
f(x) = 3^x
f(0) = 3^0
f(0) = 1
That means (0,1) is on the graph. So far so good.
-------
But let's try x = 1
f(x) = 3^x
f(1) = 3^1
f(1) = 3
Meaning (1,3) should be on the graph of y = 3^x. Instead, the graph shows (1,4) is on the red curve. We don't have a match.
The red curve shows the equation y = 4^x.

Joe is responsible for reserving hotel rooms for a company trip. His company changes plans and increases how many people are going on the trip, so they need at least 50 total rooms. Joe had already reserved and paid for 16 rooms, so he needs to reserve additional rooms. He can only reserve rooms in blocks, and each block contains 8 rooms and costs $900. Let B represent the number of additional blocks that Joe reserves. 1) Which inequality describes this scenario? 2)What is the least amount of money that Joe can spend to get the amount of rooms they need? Work not needed!
Answer:
The answer is below
Step-by-step explanation:
1) The number of rooms Joe company needs is 50. Let the number of rooms needed be n, this can be represented by the inequality:
n ≥ 50
Joe has already reserved 16 rooms, therefore the number of additional rooms needed to be reserved = 50 - 16 = 34 rooms. At least 34 rooms have to be reserved, if B is the number of additional blocks that Joe reserves, the inequality is:
B ≥ 34
2) Each block contains 8 rooms therefore the minimum number of block (a) needed to be reserved = 34/8 = 4.25 = 5 to the next whole number. Therefore the minimum number of blocks needed is given as:
a ≥ 5
Since each block cost $900, let c represent the minimum amount of money needed, therefore the least amount of money needed is given as:
c = $900(5) = $4500
c ≥ $4500
Here, we are required to determine which inequality describes the scenario in the question and the least amount of money that Joe can spend to get the amount of rooms they need.
(1) The inequality which best describes the scenario is; B ≥ 4.25.
(2) The least amount of money that Joe can spend to get the amount of rooms they need is; $4500
First, since they need at least 50 total rooms and Joe had already reserved 16 rooms.Therefore, Joe needs to reserve an additional 34 rooms to completely accomodate people who are going on the trip.And since, he can only reserve rooms in blocks with each block containing 8 rooms;The number of blocks he needs to reserve; B ≥ 4.25.
Therefore, since only whole blocks can be reserved, Joe needs to reserve 5 blocks.Therefore, since one block costs $900, then, 5 blocks will cost $900 × 5 = $4500.Read more:

Step-by-step explanation
Gas costs 1.35 per gallon and Jose had 81 dollars for gasoline
with this info we can find out how many gallons of gas Jose can buy.
81 divided by 1.35 is 60 gallons of gas
we also know that he can travel 34 miles for each gallon of gas
with this we can find out how far jose can travel
34 multiplied by 60 is 2040 miles
so, with $81, Jose can travel 2040 miles if gas prices are $1.35
Find the missing probability. P(B)=720,P(A|B)=14 ,P(A∩B)=?
Answer:
7/80
Step-by-step explanation:
Given that: P(B) = 7 / 20, P(A|B)= 1 / 4
Bayes theorem is used to mathematically represent the conditional probability of an event A given B. According to Bayes theorem:
[tex]P(A|B)=\frac{P(A \cap B)}{P(B)}[/tex]
Where P(B) is the probability of event B occurring, P(A ∩ B) is the probability of event A and event B occurring and P(A|B) is the probability of event A occurring given event B.
[tex]P(A|B)=\frac{P(A \cap B)}{P(B)}\\\\P(A \cap B)=P(A|B)*P(B)\\\\Substituting:\\\\P(A \cap B)=1/4*7/20=7/80\\\\P(A \cap B)=7/80[/tex]

Answer:
(x + 1)^2 = 1/4
Step-by-step explanation:
Here, we want to rewrite the equation by completing the square.
The equation to rewrite is;
4x^2 + 8x + 3 = 0
4x^2 + 8x = -3
divide through by the coefficient of x^2 which is 4

x^2 + 2x = -3/4
Now divide the coefficient of x by 2, square it and add to both sides of the equation.
We have;
x^2 + 2x + 1^2 = -3/4 + 1^2
x^2 + 2x + 1 = -3/4 + 1
x^2 + 2x + 1 = 1/4

Triangle H N K is shown. Angle H N K is 90 degrees. The length of hypotenuse H K is n, the length of H N is 12, and the length of N K is 6. Law of cosines: a2 = b2 + c2 – 2bccos(A) What is the value of n to the nearest whole number? 10 13 18 21
Answer:
13
Step-by-step explanation:
From the question, we are given a triangle HNK with an angle of 90°
The length of hypotenuse H K is n,
the length of HN is 12
the length of N K is 6.
From the above values, obtained in the question, we can see that this is a right angled triangle.
We are asked to find the length of the hypotenuse.
We can use Pythagoras Theorem of solve for this.
c² = a² + b²
where c = HK = n
a = NK = 6
b = HN = 12
c² = 6² + 12²
c² = 36 + 144
c² = 180
c = √180
c = 13.416407865
Approximately to the nearest whole number = 13
Therefore the value of HK = n = 13
We can also use Law of Cosines as given in the question to solve for this.
a² = b² + c² - 2ac × Cos A
where c = HK = n
a = NK = 6
b = HN = 12
Hence
c² = a² + b² - 2ab × Cos C
c = √ (a² + b² - 2ab × Cos C)
Where C = 90
c = √ 6² + 12² - 2 × 6 × 12 × Cos 90
c = 13.42
Approximately to the nearest whole number ≈ 13
Therefore the value of HK = n = 13

Given that f(x)=-x+4 and g(x)=-2x-3, solve for f(g(x)) when x=2.
Answer:11
Step-by-step explanation:
g(2)=-7
f(-7)=11
Answer:
f(g(x))= 11
Step-by-step explanation:
This question asks us to find f(g(x)) when x=2. Therefore, we can substitute 2 in for x.
f(g(x)), x=2
f(g(2))
First, we must find g(2).
We know that g(x)= -2x-3. We can plug 2 in for each x and solve.
g(x)= -2x -3, x=2
g(2)= -2(2)-3
First, multiply -2 and 2.
g(2)= -4-3
Then, subtract 3 from -4.
g(2)= -7
Let's return to our function: f(g(2)). We know that g(2)= -7. Thus, we can substitute -7 in for g(2).
f(g(2)), g(2)= -7
f(-7)
Now we must find f(-7). We know that f(x)= -x+4. We can plug -7 in for x and solve.
f(x)= -x+4 , x= -7
f(-7)= -(-7) +4
f(-7)= 7+4
Add 7 and 4
f(-7)= 11
Our final answer is: f(g(x))= 11

Answer:
when two inscribed angles in one circle both equal 75°, the two angles must intercept the same arc that measures 75°.
Step-by-step Explanation:
The relationship between an intercepted arc and an inscribed angle is given as:
the measure of the intercepted arc = twice the inscribed angle that intercepts it.
Also, by virtue of this, when two inscribed angles intercepts the same arc, both inscribed angles are said to be congruent. And the measure of both angles equal the measure of the arc they both intercept.
Therefore, if the measure of an arc, that is intercepted by 2 inscribed angles, is given as 75°, both inscribed angles equal 75° as well. Thus, each of the inscribed angles is half the measure of the intercepted arc.
Therefore, the statement that is true about inscribed angles is: "when two inscribed angles in one circle both equal 75°, the two angles must intercept the same arc that measures 75°."
