Let f(x)=x^2+2 and g(x)=1-3x Find each function value. f(g(-4))
Answer:
171
Step-by-step explanation:
First you plug -4 into the g(x) equation
g(-4)= 1-3(-4)
Use pemdas
g(-4)= 1+12
g(-4)= 13
Next you plug 13 into the f(x) equation
f(13)= 13^2 + 2
First you do 13^2=169
Add 2 and you get 171

Which choice is equivalent to the quotient below?
I think it’s B. ?
PLEASE HELP!!
The choice equivalent to the quotient below is option D. 2.
What is Square Root?Square root of a number is the value such that the value when multiplied to itself two times gives the original number.
It is denoted by the symbol √.
For example, square root of 16 is 4 since 4 × 4 = 16
Given expression is
√100 / √25
We have to find the square root of each of the value and then divide it.
We know that,
100 = 10 × 10
So 100 = 10²
So,√100 = 10
Similarly,
25 = 5 × 5
So √25 = 5
Substituting the values,
√100 / √25 = 10 / 5 = 2
Hence the quotient is 2.

Find the area of each figure and round to the nearest tenth if necessary
Given:
The figure of two semicircles with diameters 6 cm and 5 cm.
To find:
The area of the combined figure.
Solution:
It is given that the diameters of the semicircles are 6 cm and 5 cm so their radii are 3 cm and 2.5 cm respectively.
Area of a semicircle is:
[tex]A=\dfrac{1}{2}\pi r^2[/tex]
So, the combined area of two semicircles with radii 3 cm and 2.5 cm is:
[tex]Area=\dfrac{1}{2}\pi (3)^2+\dfrac{1}{2}\pi (2.5)^2[/tex]
[tex]Area=\dfrac{1}{2}\pi (9)+\dfrac{1}{2}\pi (6.25)[/tex]
[tex]Area=14.137167+9.817477[/tex]
[tex]Area=23.954644[/tex]
Round the value to the nearest tenth (one decimal place.
[tex]Area\approx 24.0[/tex]
Therefore, the area of given figure is 24.0 sq. cm.

A corporation is under orders to reduce the time office workers spend filling out their TPS reports. Previously the average time spent on the TPS report was 6.3 hours. In order to test whether the time to fill out the TPS report has been reduced, a sample of 48 office workers was randomly chosen, and their completion times recorded. The mean completion time for their TPS reports was 5.7 hours with a standard deviation of 1.8 hours. In order to test that the time to complete the TPS report has been reduced, state the appropriate null and alternative hypotheses.
Answer:
The null hypothesis, H₀ is that the mean completion time for the TPS report remains at the duration of 6.3 hours
The alternative hypothesis, H₁ is that the mean completion time for the TPS report is less than 6.3 hours
Step-by-step explanation:
The given parameters are;
The average time spent on the TPS report = 6.3 hours
The number of workers in the sample used for the test = 48 office workers
The mean completion time of the TPS report for the sample = 5.7 hours
The test aim; To find out whether the mean time required to fill out the TPS report has been reduced
The null hypothesis, is H₀; μ = 6.3 hours
The alternative hypothesis, H₁; μ < 6.3 hours

Write the first six terms of the sequence, beginning with n=1. a(n)=60n Enter the numbers, separated by commas.
Answer:
60, 120, 180, 240, 300, 360
Step-by-step explanation:
a(n)=60n
At n =1
a(1) = 60(1) = 60
At n = 2
a(2) = 60(2) = 120
At n = 3
a(3) = 60(3) = 180
At n = 4
a(4) = 60(4) = 240
At n = 5
a(5) = 60(5) = 300
At n = 6
a(6) = 60(6) = 360
60, 120, 180, 240, 300, 360

A box is to be wrapped in a shiny pink decorative paper. The box is 99 inches long, 55 inches wide, and 44 inches high. What is the minimum amount of decorative paper needed to cover the box?
Answer:
24442 square inches of decorative paper
Step-by-step explanation:
To solve for the above question, we have to find the Surface Area of the box. The box is shaped as a Rectangular Prism.
Hence, the formula is given as:
A = 2(wl + hl+ hw)
Where:
Length (l) = 99 inches
Width (w) = 55 inches
Height (h) = 44 inches
=2 × (55×99 + 44×99 + 44×55)
=24442 square inches
Therefore, the minimum amount of decorative paper needed to cover the box is 24442 square inches of decorative paper.
In 1947, milk cost $0.75 per gallon and bananas cost $0.15 per pound. Donna bought two gallons of milk and some bananas for a total of $2.25 in 1947. How many pounds of bananas did she buy?
Answer:
Answer is 5 pounds of bananas
Step-by-step explanation:
Required milk:
Milk= 2 gallons
Milk cost per gallon=$0.75
so,
2*0.75
$ 1.5
total amount =$2.25
to calculate bananas
$2.25-$1.5=$0.75
per pound cost of bananas =$0.15
$0.75/$0.15
5 pounds of bananas
Dona bought 5 pounds of banana and 2 gallons of milk for a total of $2.25.
What are linear and non-linear functions?A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.
Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.
An example of a non-linear function is a quadratic function.
Given, In 1947, milk cost $0.75 per gallon and bananas cost $0.15 per pound.
Let,The cost of one gallon of milk is 'x' dollars and the cost of one pound of banana is 'y' dollars.
Also given Donna bought two gallons of milk and some bananas for a total of $2.25.
Therefore, 2(0.75) + 0.15y = 2.25.
0.15y = 2.25 - 1.5.
0.15y = 0.75.
y = 0.75/0.15.
y = 5.
So, Dona bought 5 pounds of bananas.

If the tangent is drawn from the outside of the circle. Then the length of the tangents will be same. Then the perimeter is 30 cm.
What is the perimeter of a triangle?Let the triangle be ABC. Then the perimeter of the triangle will be
Perimeter = AB + BC + CA
Now,
We know that if the tangent is drawn from the outside of the circle. Then the length of the tangents will be same.
Then the completed diagram is given below.
Hence, We get;
The perimeter of the graph of figure is,
P = 3 + 3 + 3 + 3 + 9 + 9
P = 30 cm
Thus, The perimeter of the graph of polygon is,
P = 30 cm
