Use the cubic model y=5a^3-2a^2+a-45 to find the value of y when x=4.

Answers

Answer:

y = 247

Step-by-step explanation:

The given cubic model that expresses the value of y is

y = 5a³ - 2a² + a - 45

We have to find the value of y at a = 4

We can calculate the value of y by putting a = 4

y = 5(4)³ - 2(4)² + 4 - 45

= 5(64) - 2(16) - 41

= 320 - 32 - 41

= 247

y = 247

easy
remember: exponents first

y=5(4³)-2(4²)+4-45
y=5(64)-2(16)-41
y=320-32-41
y=288-41
y=247

answer is 247

A rectangular swimming pool is 25 ft long and 20 1/2 ft wide, and it must be filled to a depth of 4 1/2 ft. One cubic foot of water is equal to 7 1/2 gallons. How many gallons of water will it take to fill the pool?

Answers

ANSWER

307½ gallons of water

EXPLANATION

The volume of the rectangular swimming pool is

$V = l * w * h$

where l=25ft and w=20½ ft.

when it is filled to a depth of 4½ ft ,then the height is , h=4½ ft.

We substitute these values into the formula to get:

$V = 25* 20.5* 4.5$

$V = 2306.25 {ft}^(3)$

If one cubic foot of water is 7½ gallons, then 2306.25 cubic feet will be

$(2306.25)/(7.5) = 307.5gallons$

We need 307.5 gallons of water to fill the pool.

First of all, she wants to INCREASE her steps per day. A, B, and C all have the same number of steps or fewer steps. I can further prove that the answer is D because if she stars walking 10 extra steps per day, 10 times 100 = 1000 and 5000 + 1000=6000. Please correct me if I am wrong because everybody makes mistakes sometimes. Also, thanks so much for giving me brainiliest!
