Write the function rule g(x) after the given transformations of the graph of f(x) = 9x.
reflection in the x-axis; vertical compression by a factor of 1/3
g(x) = []
The function rule after the given transformation is g(x) = -3x
What is a function?A function is defined as a relation between a set of inputs having one output each.
We have,
f(x) = 9x
Vertical compression = 1/3
Reflection in x-axis.
We know that when we compress a function f(x) by scale factor m
The new compress function is represented:
F(x) = m(f(x))
Reflection across the x-axis changes the sign of the new function.
Now,
With the vertical compression:
F(x) = 1/3 (f(x))
F(x) = 1/3(9x) = 3x
With the reflection in the x-axis:
g(x) = - F(x)
g(x) = -3x
Thus the function rule after the given transformation is g(x) = -3x

After five months, the percentage decrease in the daylight is 51.815%
As per the question, On the first day of June, there was 16.81 hours of daylight in a city and five months later, there was 8.10 hours of daylight. We are supposed to find the percent decrease in the daylight.
Percentage increases or decreases are calculated by setting the problem up proportionally.
We are trying to calculate at what percentage of 16.81 is 8.10 first
Let "x" be the percentage required percentage
therefore [tex]\frac{x}{100} =\frac{8.10}{16.81}[/tex]
[tex]x = \frac{8.10*100}{16.81} \\x=\frac{810}{16.81} \\x=48.185%[/tex]
8.10 is approximately 48.185% of 16.81.

Answer:
170 ft²
Step-by-step explanation:
4ft = 48 in
You then multiply 48 by each given side.
48 in · 4.25in = 204 in
Divide by 12 to get answer in feet.
204 in ÷ 12 = 17
So the actual length of the side labeled 4.25 in is 17 ft.
48 · 2.5 = 120
Divide by 12 to get the answer in feet.
120 ÷ 12 = 10
The actual length of the side labeled 2.5in is 10 ft.
Area= L x W
Area= 17ft · 10ft = 170 ft²

Paying monthly, at the end of 12 months Colin pays $___
Colin pays $___ more monthly than he would annually.
Colin pays (to the nearest percent) ___% more by paying monthly than he would paying annually.
Paying monthly premium, at the end of 12 months Colin pays $1,155.36
Colin pays $95.36 more monthly than he would annually.
Colin pays (to the nearest percent) 8.99 % more by paying monthly premium than he would paying annually.
What is monthly and annual premium?Premium is the amount of money one has to pay to insurance companies so that they provide us coverage at the time of need.
If we make payments monthly, the the premium is monthly.
If we pay the amount at the end of the year, then the premium is annual.
Given that Edmond has a $60,000 term life policy. The annual premium is $1,060. Colin pays $96.28 monthly.
Monthly premium of Edmond = $96.28
If he pays monthly, then total payment at the end of 12 months
= 12 *$96.28 = $1155.36
Then total payment at the end of 12 months is greater than the annual premium by = 1,156.36 - 1,060 = 95.36
Percentage of extra amount paid when colin paid monthly
= (extra payment made/ annual payment ) *100 = (95.36/1,060)*100 =8.99 %
Therefore, Colin pays 8.99 % more by paying monthly than he would paying annually.

A prism and two nets are shown below:
Image of a right triangular prism and 2 nets. The triangle bases have base 4, height 3, and diagonal side 5. The length of the prism from the bases is 8.6. Net A has 3 rectangles in a row. The middle one has sides AC and CD. This middle one has triangle ABC on top and identical triangle below. Net B is the same except that the triangle base ABC is on top of the last rectangle which has sides AC and CD. Units are in inches.
Part A: Which is the correct net for the prism? Explain your answer.
Part B: Write the measurements of Sides AB, BC, and CD of the correct net.
Part C: What is the surface area of the prism? Show your work.
Step-by-step explanation:
a) Imagine folding the net into the shape. In this case, Net A can have both triangles fold up, and both rectangles fold in to make the above shape.
b) Side AB on this net is the height of the triangle, 3 inches.
Side BC is the same as the hypotenuse (diagonal) on the triangle, which . is 5 inches.
Side CD is the same as the length of the shape, which is 8.6 inches.
c) Surface area = area of all sides
Triangle = 1/2 bh
= 2*3
= 6 inches squared
There are two triangles, so that adds to 12 inches squared.
Now all of the rectangles:
Left most = 3*8.6
= 25.8 inches squared
Middle = 4*8.6
= 34.4
Right most = 5*8.6
= 43
Now we can add all of this:
43 + 34.4 + 25.8 + 12
= 115.2 inches squared.
This is the surface area of the prism.

Suppose that a classroom has 8 light bulbs. The probability that each individual light bulb works is 0. 8. Suppose that each light bulb works independently of the other light bulbs. What is the probability that all eight of the light bulbs work?.
0.1678 is the probability that all the light bulbs work
Define probability?
Probability is a branch of mathematics and can be defined as the one which deals with the explanation of the possibility of an event to occur or take place. Probability has a range between 0 to 1. In probability, 0 indicates the impossibility of an event to occur and 1 indicates the certainty of that event to occur or take place.
As the light bulbs are not dependent on each other and work independently, the probability that all eight of the light bulbs will work can be calculated by multiplying the probability of each of the eight light bulbs.
As the probability of each of the eight light bulbs to work = 0.8
probability all the eight light bulbs work = 0.8^8
probability all the eight light bulbs work = 0.1678

Find the amount in a continuously compounded account for the given conditions.
principal: $ 500 ; annual interest rate: 4.9 % ; time: 2.5 years
The amount in a continuously compounded account is $ 565.2 .
If compound interest is calculated and reinvested into the balance of an account across an essentially unlimited number of periods, continuous compounding is the mathematical limit that compound interest can reach.
The amount in the continuously compounded account is given as:
[tex]A=Pe^{rt}[/tex]
Where P is the principal amount, r is the interest rate, and t is the time period in years.
Now, we have
The principal amount, P = $500
Annual interest rate, r = 4.9 % = 4.9 / 100 = 0.049
Time = 2.5 years
Therefore, the amount in a continuously compounded account is:
[tex]\[A=Pe^{rt}\][/tex]
[tex]A = $500 \times e^{0.049 \times 2.5}[/tex]
[tex]A = $500 \times e^{0.049 \times 2.5}[/tex]
[tex]A = $500 \times e^{0.1225}[/tex]

offer a complete crab dinner as well as a vegetarian option. One troop member sold tickets
for 23 crab meals and 34 vegetarian meals, with total receipts of $1,930. Another sold tickets
for 20 crab meals and 38 vegetarian meals, bringing in a total of $1,906. How much do the
two types of tickets cost?
A ticket for a crab meal costs $
and a ticket for a vegetarian meal costs $
The ticket for a crab meal costs $44 and a ticket for a vegetarian meal costs $27
From the question, we are to solve the system of equations.
First, we will form the system of equations
Let x represent the ticket for a crab meal and y represent the ticket for a vegetarian meal
From the given information,
"One troop member sold tickets for 23 crab meals and 34 vegetarian meals, with total receipts of $1,930"
That is,
23x + 34y = 1930 -------------- (1)
Also,
"Another sold tickets for 20 crab meals and 38 vegetarian meals, bringing in a total of $1,906"
20x + 38y = 1906 -------------- (2)
Now, solve the equations simultaneously
Multiply equation (1) 20 and equation (2) by 23
20 × [23x + 34y = 1930
23 × [20x + 38y = 1906
460x + 680y = 38600
460x + 874y = 43838
Subtracting the resulting equations, we get
-194y = -5238
y = -5238/-194
y = 27
Substitute the value of y into equation (1)
23x + 34y = 1930
23x + 34(27) = 1930
23x + 918 = 1930
23x = 1930 - 918
23x = 1012
x = 1012/23
x = 44
Hence, the ticket for a crab meal costs $44 and a ticket for a vegetarian meal costs $27
