Divide the following polynomials, then place the answer in the proper location on the grid. write the answer in descending powers of a. divide 5a^2 + 6a - 9 into 25a^4 + 19a^2 - a - 78.

Step-by-step explanation:

(25a^4           +  19a^2  -    a  -  78) : (5a^2 + 6a - 9)  =  5a^2 - 6a + 20   Rest  -175x + 102  

25a^4  + 30a^3  -  45a^2

step-by-step explanation:

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.
