Find f(x) and g(x) so the function can be expressed as y = f(g(x)).
y =2/x^(2) + 3

Answers

We are asked to find f(x) and g(x) so the function can be expressed as y = f(g(x) such that y = y =2/x^(2) + 3. There are many possibilities here but we go to the simplest ones. we can have g (x) = x2 and f(x) is equal to 2/x + 3.

One possible answer is:

f(x) = (2/x) + 3 and g(x) = x².

Explanation:

We are to write this equation as y = f(g(x)). This means we want it to be a composite of functions; in f(x), we take the value of g(x) and use in place of x.

If we let g(x) = x², this means everywhere we see an x in f(x), we will replace it with x². To make our equation y = 2/x² + 3, working backward we would substitute x for x²; this would give us f(x) = 2/x + 3.

Triangle RST is the pre-image of triangle UVW with a scale factor of 3. Find the area of triangle UVW if the area of triangle RST is 9 cm2. a.) Set up an equation on how to solve for the missing area using the Area Ratios for Similar Figures.

b.) What is the area of triangle UVW?

Answers

A. (Area of triangle UVW)/(Area of triangle RST)=3^2=9
B. Substitute Area of triangle RST=9 into the equation above.

(Area of triangle UVW)/9=9
Area of triangle UVW =9x9=81 cm^2

Ralph jordan recently bought a new lawnmower for 228.00. If he had to pay 6% sales tax on the lawnmower, what wasthe total cost of the lawnmower?A:$251.62
B: 234.00
C:241.68
D:312.42

Answers

First we find what 6% of 228.00 is.

To do that we would multiply the number by the percent
So 228 x 6 = 1368
Then divide the answer by 100.
1368/100 = 13.68

You can round if you would like but in this case I believe we should leave it alone.

Which means the price was 228.00 and the tax was 13.68 we just have to add them together to find the answer.

228.00 + 13.68 = 241.68

The answer would be C.
