<u>Answer:</u>

0.45m + 33

<u>Step-by-step explanation:</u>

We are instructed to multiply the number the number of minutes Mr. Frotout spent on long distance calls by 0.45 the long distance rate then add 33 the flat monthly charge.

Assuming the number of long minutes spent on long distance calls by Mr. Frotout to be $m$ , we can express the given situation as follows:

$0 . 4 5 m + 3 3$

Y=3/4x^2+9x vertex form?

Nutka1998 [239]

The standard form:

$f(x)=ax^2+bx+c$

The vertex form:

$f(x)=a(x-h)^2+k\\\\h=\dfrac{-b}{2a};\ k=f(h)$

We have

$y=\dfrac{3}{4}x^2+9x\to f(x)=\dfrac{3}{4}x^2+9x\\\\a=\dfrac{3}{4},\ b=9,\ c=0\\\\h=\dfrac{-b}{2a}\to h=\dfrac{-9}{2\cdot\frac{3}{4}}=\dfrac{-9}{\frac{3}{2}}=-9\cdot\dfrac{2}{3}=-3\cdot2=-6\\\\k=f(h)\to k=f(6)=\dfrac{3}{4}(-6)^2+9(-6)=\dfrac{3}{4}(36)-54\\=(3)(9)-54=27-54=-27$

Answer:

$y=\dfrac{3}{4}(x-(-6))^2+(-27)=\dfrac{3}{4}(x+6)^2-27$
