G(r)=−(r+11)(r+14)
Oduvanchick [21]

Answer:

The zeros are

Larger r=-11

Smaller r=-14

2)The vertex is (-12.5,-2.25)

Step-by-step explanation:

The given function is:

g(r)=(r+11)(r+14)

This function is already in the factored form therefore it is easy to find the zeros,

(r+11)(r+14)=0

Either (r+11)=0 or (r+14)=0

The zeros are r=-14 or r=-11

b) The expanded form of the given function is:

g(r)=r^2+25r+154

We obtain the vertex form by completing the square:

g(r)=r^2+25r+(\frac{25}{2})^2+154-(\frac{25}{2})^2

The vertex form is:

g(r)=(r+\frac{25}{2})^2-(\frac{9}{4}

Therefore the vertex is (-12.5,-2.25)

Given 1 = 123° and 8 = 7z + 11.<br><br> What is the value of z, if lines a and b are parallel?
Serga [27]

Answer:

z=16

Step-by-step explanation:

We know for sure that since A and B are parallel that 1, 4, 5, and 8 are equal.

So then the equation is simply 123=7z+11---> 7z=112----> z=16
