Answer:

  f(g(x)) = -3x^2 -2x -3

Step-by-step explanation:

<u>Given</u>:

  f(x) = -x-7

  g(x) = 3x^2 +2x -4

<u>Find</u>:

  f(g(x))

<u>Solution</u>:

Substitute per the function definitions.

  f(g(x)) = f(3x^2 +2x -4) = -(3x^2 +2x -4) -7

  f(g(x)) = -3x^2 -2x -3

line j is perpendicular to lines m and n. if the products of the slope of all three lines is -8, what is the slope of line j?
jeka94

Answer:

the slope of line j is -1/8, the slope of lines m and n are both 8.

Explanation step by step:

Suppose j is the slope of line j, m the slope of line m and n the slope of line n. Since:

1. line j is perpendicular of line m, so j*m= -1

2. J is perpendicular of line n, so  j*n=-1

3. m and n and parallel so m=n

As we want to know the slope of j we clear the equations presented to us in order to find it.

(1) m* n* j = -8, since n=m we have  n^{2}* j = -8.

we clear j; n^{2} * j = -8 \\ j =\frac{-8}{n^{2} }

replacing in the equation n*j = -1 we get

n*(-8/n^2) = -1. Thus n = 8. Since j = -1/n = -1/8.

Wendy deposited $2,250 into a savings
guapka [62]

Answer:

$2410.26

Step-by-step explanation:

principal, p=$2250

rate, r=3.5%

interest, i at the beginning of 1st year = p*r=2250*3.5/100

i=$78.75

amount at the end of 1st year = 2250+78.75=$2328.75

interest at the beginning of 2nd year = 2328.75*3.5/100

i=$81.50625

amount at the end of 2nd year=2328.75+81.50625

=$2410.26
