Find f(g(3)) given:
*
f (x) = 2x2 – 1
g(x) = 3x
h(x) =
j(x) = x - 5
Answer:
161
Step-by-step explanation:
Given the functions
f (x) = 2x^2 – 1
g(x) = 3x
we are to find f(g(3))
First look for the composite function f(g(x))
f(g(x)) = f(3x)
f(3x) = 2(3x)² - 1
f(3x) = 2*9x² - 1
f(3x) = 18x² - 1
f(g(x)) = 18x² - 1
Substitute x = 3 into the result
f(g(3)) = 18(3)² - 1
f(g(3)) = 18*9- 1
f(g(3)) = 162-1
f(g(3)) = 161
Hence f(g(3)) is 161

The student council at Eleanor Roosevelt High School is taking a survey of student opinions on this year's homecoming theme. To decide who to survey, the council creates a master alphabetized list of names from every student in the school, then selects every 20th student from the list. Will the results of this survey be valid? Why or why not?
yes, because a random sample is taken from all of the student body
yes, because the survey will include all of the seniors
no, because the survey will include freshman
no, because the survey will not include members of the faculty
Answer:
no, because the survey will not include members of the faculty

Step-by-step explanation:
Adam has 3 coins in his pocket and they are all different from each other. Ben has 3 coins in his pocket and they are all the same as each other. Adam has half as much money as Ben.
What are the coins they each have?
Answer:
The possible coins are:
P = penny = $0.01
N = nickel = $0.05
D = dime = $0.10
Q = quarter = $0.25
H = half dollar = $0.50
We know that Adam has 3 coins in his pocket, and all of them are different, then the money that Adam has can be represented with (A + B + C)
Behn has 3 coins, and all of them are the same, then if his coin has a value X, he has a total of 3*X
We know that Adam has half as much money as Ben, this can be written as:
(A + B + C) = 3*X/2
The easier way to solve this, is to play with different values of X, and see if we can find the values of A, B and C.
For example, if X = $0.10
then:
(A + B + C) = $0.10*(3/2) = $0.15
We can find 3 different value of coins for this equation? No, we cant, so X = $0.10 is also discarded.
if x = $0.50 then:
(A + B + C) = (3/2)*$0.50 = $0.75
Here we could have:
A = $0.50
B = $0.25
then: A + B = $0.75
But we still have the coin C.
If we take X = $0.25 then:
(A + B + C) = (3/2)*$0.25 = $0.375
We could round the right part to $0.40
then the coins in the left part would be:
A = $0.25
B = $0.10
C = $0.05
A + B + C = $0.25 + $0.10 + $0.05 = $0.40
This is a strech, but is the only thing we can make with the given problem.

A restaurant needs to build a wheelchair ramp for its customers. The angle 2 of elevation for a ramp is recommended to be 5 degrees. If the vertical distance from the sidewalk to the front door is two feet, what is the horizontal distance that the ramp will take up? Round your answers to the nearest hundredth. * O a) 22.9 ft O b) 26.4 ft O c) 22.8 ft O d) 22.2 ft
Answer:
Step-by-step explanation:
An escalator at a shopping center is 200.75 feet long and rises at an angle of 15⁰. What is the vertical rise of the escalator? Round to hundredths place
The horizontal distance that the ramp will take up is a) 22.9 ft.
What are trigonometric ratios in terms of a right-angle triangle?We know a right-angled triangle has three sides they are -: Hypotenuse,
Opposite and Adjacent.
We can remember SOH CAH TOA which is,
sin = opposite/hypotenuse, cos = adjecen/hypotenuse and
tan = opposite/adjacent.
Given, The vertical or opposite distance is 2 feet and it has an angle of 5°.
∴ The horizontal or adjacent distance can be obtained by tan(theta).
Assuming horizontal distance to be x feet.
∴ tan(5°) = 2/x feet.
x = 2/tan(5°).
x = 22.9 feet.

A scuba diver dove 40 feet below the surface. He swam up 12 feet to see a unique fish. He followed the fish down 8 feet. Then he followed the fish up 27 feet. How far below the surface is the diver now?
Answer: 9 feet below the surface.
Step-by-step explanation:
The scuba diver starts 40 ft below the surface. We can represent the position of the scuba diver as:
Position = -40ft
Where the negative sign is because it is below the surface of the water, so
"He swam up 12 feet to see a unique fish."
Now we need to add 12ft
Then his new position is:
Position = -40ft + 12 ft = -28ft
"He followed the fish down 8 feet.
Now we need to subtract 8ft
His new position is:
Position = -28ft - 8 ft = -36 ft
"Then he followed the fish up 27 feet."
Now we add another 27 ft.
The final position will be:
Position = -36ft + 27ft = -9ft
Then the final position of the scuba diver is -9ft, that means that he is 9 feet below the surface.
