What are the zeros of the following function?
y = x2 + x - 12
A.-4, 3
B.4, -3
C.-6, 2.
D.6, -2

Answers

answer: A, -4, 3

you set up the equation by making it equal to zero. so it’s x^2 + x - 12 = 0

then you solve for x

you do this by factoring. you do this by saying what multiplies to -12 and then adds up to 1 since your a times c is -12 and your b is 1

4 and -3 work. so we do (x+4) (x-3) = 0

(x+4) = 0 is -4
(x-3) = 0 is 3

so your answer is A, -4, 3

an object is moving at a speed of 6 miles per month. express this speed in feet per hour. Don’t have to round anything up

Answers

Answer: 44 feet.

Step-by-step explanation: If the object is moving at a speed of 6 miles per month, that's 6 miles for every 720 hours at the very least. That's 1 mile for every 120 hours. That's 5280 feet for every 120 hours. The object is moving 44 feet every hour.

The speed of the object is 43.39 feet per hour.

What is unit conversion?

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 minute = 60 seconds

1 km = 1000 m

We have,

6 miles = 1 month

1 miles = 5280 feet

1 month = 730 hours

Now,

6 miles = 6 x 5280 feet

6 miles = 31680 feet

So,

31680 feet = 730 hours

Divide both sides by 730.

31680/730 feet = 1 hour

43.39 feet = 1 hour

Thus,

Speed is 43.39 feet per hour.

The perimeter of a square courtyard is 144 m. Find the cost of cementing it at the rate of £5 per m². *

Answers

Answer:

the cost is   £ 6,480

Step-by-step explanation:

given:

The perimeter of a square courtyard is 144 m

find:

the cost of cementing it at the rate of £5 per m².

Perimeter = 4 Sides

144 = 4 S

S = 144/4

S = 36

Area = S²

A = 36²

A = 1296 m²

cost of cementing the area =   1296 m² x £5 per m²  =  £ 6,480

therefore,

the cost is   £ 6,480

Gerry deposited $1,230 in an account that pays 2.19% simple interest for one year.
a. How much interest will he earn in one year?
$
b. What will his balance be after one year?
$

Answers

Answer: See explanation

Step-by-step explanation:

a. Simple interest is calculated using the formula: PRT/100

where P = principal = $1230

R = rate = 2.19%

T = time = 1 year

We then slot the values into the formula

= PRT/100

= (1230 × 2.19 × 1)/100

= 2693.7/100

= $26.937

b. Balance = Principal + Interest

= $1230 + $26.937

= $1256.937
