Troyanec [42]3 years ago
5 0

When the exponent is 0, it will always equal 1.

For example:

x^0=1

3^0=1

Since you know the values of m and n, substitute/plug it into the equation:

m^0-n^2   Plug in 2 into "m" since m = 2, and plug in -1 into "n" since n = -1

(2)^0-(-1)^2    

1 - (1)

0           Your answer is B

Gary's parents want him to attend The University of Houston. They opened a college savings account 15 years ago. Today, average
Vikki [24]

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Today, average yearly tuition and fees for one year at the university are about $10,350.

I will assume a yearly interest rate of 8%.

<u>First, we need to calculate the total amount needed:</u>

Future value (FV)= 10,350*4= $41,400

<u>Now, using the following formula, the annual deposit required:</u>

FV= {A*[(1+i)^n-1]}/i

A= annual deposit

Isolating A:

A= (FV*i)/{[(1+i)^n]-1}

A= (41,400*0.08) / [(1.08^15) - 1]

A= $7,194.22

You need to construct fence around an area of 3136 ft2. What are the dimensions of the rectangular pen that minimize the amount
borishaifa [10]

Answer:

Step-by-step explanation:

The the area of the rectangular pen be A = LW

L is the length

W is the width

Given

A = 3136ft²

3136 = LW..........1

Given the perimeter P = 2L+2W....... 2

From 1; L = 3136/W

Substitute into 2

P = 2(3136/W)+2W

P = 6272/W + 2W

In order to minimize the amount of material needed, then dP/dW = 0

dP/dW = -6272/W² + 2

0 = -6272/W² + 2

6272/W² = 2

cross multiply

6272 = 2W²

W² = 3136

W = √3136

W = 56ft

Since A = LW

3136 = 56L

L = 3136/56

L = 56ft

Hence the dimensions of the rectangular pen that minimize the amount of material needed is 56ft by 56ft
