Answer:

Both m^2 and cm^2 are given below. Take your pick.

Step-by-step explanation:

Area = L * W

L = 1.57 m * 100 cm / 1 meter = 157 cm

W = 45 cm

Area = 157 cm * 45 cm = 7065 cm^2

In meters, the width would be 45 cm * 1 m / 100 cm = 0.45 m

Area = L * W

L = 1.57 m

W = 0.45 M

Area = 1.57 * 0.45

Area = 0.7065 m^2

3200 dollars is placed in an account with an annual interest rate of 8.25%. To the nearest tenth of a year, how long will it tak

frozen [14]

It takes 24 years for the account value to reach the $9600.

Step-by-step explanation:

From the given data, it can be determined that :

Amount = $9600
Principal = $3200
Rate = 8.25% = 0.0825

Number of years should be calculated.

To find the interest :

Amount = Principal + Interest

Therefore, the interest can be calculated by the formula,

Interest = Amount - Principal

⇒ 9600 - 3200

⇒ 6400

The interest needed is 6400.

To find the number of years required to reach this interest :

Use the formula for simple interest,

Simple interest = Pnr /100

where,

P is the principal
n is the number of years
r is the rate

Substitute all the given values in the simple interest formula,

Simple interest = 3200 × n × 0.0825

6400 = 264 n

n = 6400 / 264

n = 24.2 which is approximately 24 years.

Therefore, it takes 24 years for the account value of 3200 dollars to reach 9600 dollars.

which of the following represents a relation that is not a function? a. x -8 -6 7 10 y 33 31 39 33 b. x -8 -6 0 3 y 33 31 39 33

boyakko [2]

X => -8 -6 -8 3
y => 33 31 39 33
is not a function because the x value -8 results to two different y-values 33 and 39.

Solve by factoring p² + 16p +64 = 0 i like highkey don’t know how to do this

bonufazy [111]

Answer:

-8

Step-by-step explanation:

When you factor, you just find two numbers that add to be the first number (16) and multiply to be the second number (64). 8 and 8 both do this. So when we factor, we also add the variable into each equation because it also has been divided into two equations, and we get: (p + 8)(p +8). Notice that the equations are "+8" and not "-8" because two +8s add to give us a +16 and multiply to give us a +64. After that, we just solve the two equations to find the solutions. Subtract 8 from each equation (we do the opposite operation because 8 is positive) to get -8. Because the answer for each equation is the same our answer is -8.
