Find the vertex and zeros of the parabola

Vertex:

Zeros:  and

Step-by-step explanation:

1) Find the x-coordinate of the vertex

where the equation is

2) Find the y-coordinate of the vertex

Plug the x-coordinate back into the original equation

Therefore, the vertex of the parabola is .

3) Find the zeros of the parabola

Rewrite the equation so that it equals 0

Divide both sides by -16

Simplify the fraction

Complete the square; first isolate t²-t

Complete the square; Add to both sides

Take the square root of both sides

Isolate t

Find the zeros

Therefore, the zeros of the parabola are and .

I hope this helps!

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

answer: 5 17/33 % (to the tenth)

step-by-step explanation:

he guessed: 34.5 pounds

actual weight is 32.7

there for he is off:

34.5 -32.7 = 1.8

32.7 is the 100%

1.8 represents %? of 32.7

therefore:

32.7   - 100%

1.8     -     x%

x= 1.8*100%/32.7% = 18*100%/327%

x=1800%/327%   = (5 165/327)%

to the tenth:

5 17/33 %
