S(x) = 2 - x²

t(x) = 3x

s(t(x)) = st(x)

s(t(x)) :

s(3x)

So in s(x) = 2 - x²,  to solve for s(3x) we replace x with 3x

s(x) = 2 - x²

s(3x) = 2 - (3x)²

          =  2 - 9x²

st(x) = 2 - 9x²

st(-7) = 2 - 9*(-7)(-7)

         = 2 - 9*49 = 2 - 441 = -439

st(-7) = -439

Julli [10]

Answer: 398.5750

Step-by-step explanation:

It is important to remember that the fourth digit after the decimal point is in the ten-thousandth place.

Then, given the  following number:

398.574986215

You can follow these steps in order ti round it to the nearest ten-thousandth:

1. You can identify that the digit in the ten-thousandth place is:

9

2. Identify the digit to the right of 9. This is:

8

3. Since:

 8>5

 You must round up. Increase the digit 9 by 1. (Notice that 9+1=10, then the digit to the left of  9 increases by 1 too). Then:

398.5750
