<h3>Explanation:</h3>

Equation: g(x) = -16x² + 64x + 80

In order to find the maximum:

vertex : -b/2a

= -64/2(-16)

= -64/-32

= 2

Maximum Height:

= -16(2)² + 64(2) + 80

= 144 ft

The vertex should be maximum as a is negative and parabola opening downwards

x coordinate of vertex

-/2a
-64/-32
2

y coordinate is max height

-16(2)²+64(2)+80
-16(4)+128+80
-64+128+80
128+16
144ft

Vertex at (2,144)

The rocket would take 2s

Hillary is making a blanket for her mom. Three fourths of the blanket is green and the rest is yellow. Two thirds of the yellow

Leviafan [203]

Answer:

1/6

Step-by-step explanation:

Hillary is making a blanket for her mom.

Let the total blanket = 1

Three-fourths of the blanket is green and the rest is yellow.

The fraction for the rest(yellow portion) = 1 - 3/4

The Lowest Common Denominator is 4

Hence,

4 - 3 /4 = 1/4

Two-thirds of the yellow part has her name on it.

The fraction of the blanket that will have her name on it is calculated as

2/3 of 1 /4

= 2/3 × 1/4

= 1/6

The grounds keeper of Estofer Park has to mow 14,623 sq. ft. of grass. He can mow 13 sq. ft of grass in one minute. How many min

MA_775_DIABLO [31]

Answer: $1,124\frac{11}{13}\ minutes$

Step-by-step explanation:

Let be "x" the time in minutes that will take him to mow the entire park.

You know that he can mow 13 square feet in 1 minute and he has to mow 14,623 square feet.

Then, you can write the following proportion:

$\frac{1}{13}=\frac{x}{14,623}$

Solving for "x", you get:

$x=\frac{14,623}{13}\ min$

To write that improper fraction as a mixed number:

- The quotient when you divide the numerator by the denominator of the fraction obtained, is $1,124$ (This will be the whole number).

- The remainder of that division is $11$ (This will be the numerator of the fraction).

- The denominator does not change.

Then:

$x=1,124\frac{11}{13}\ min$

Hoochie [10]

A = 23,000(1 + .03/365)^365(30)
A = 23,000(1.000082192)^10950
The answer is $56,569 or $56,568.92

Hope this helps :)
