You could do this step by step or all in 1 statement. I will do it step by step because that's the way I would teach it.

i1 = 4 * (1/2)^(1 - 1) Reduce the power

i1 = 4 * (1/2)^0 Change 1/2 to 1

i1 = 4 * 1 = Multiply 4

i2 = 4 * (1/2)^(2- 1) Same directions as above

i2 = 4*(1/2)^1

i2 = 4*1/2 = 2

i3 = 4 * (1/2)^(3 -1) Same directions as above.

i3 = 4 * (1/2)^2

i3 = 4 * 1/4

i3 = <u>1</u>

Total 7

Elle and heather drew floor models of there living rooms.Elles model respresented 20 feet by 15 feet.Heathers model respresented

Answer:

Heather's model represents the greater area.
$24\ ft^2$ greater.

Step-by-step explanation:

The formula for calculate the area of a rectangle is:

$A=lw$

Where "l" is the lenght of the rectangle and "w" is the width.

The formula for calculate the area of a square is:

$A=s^2$

Where "s" is the side lenght.

In this case, knowing that Elle's model represented 20 feet by 15 feet, we can say that:

$l=20\ ft\\w=15\ ft$

Therefore, substituting these values into the formula $A=lw$ , we get that the area is:

$A_1=(20ft)(15ft)=300\ ft^2$

Since Heather's model represented 18 ft by 18 feet, we can identify that:

$s=18ft$

Substituting this value into $A=s^2$ , we get this area:

$A_2=(18ft)^2=324\ ft^2$

Notice that Heather's model represents the greater area.

To calculate how much greater it is, subtract the areas. Then:

$324\ ft^2-300\ ft^2=24\ ft^2$

What is the solution set? 3.3x - 11.6 > 18.1 Enter your answer in the box. PLEASE HELP!

adelina 88 [10]

Hi

3.3x - 11.6 > 18.1
3.3x > 18.1 + 11.6
3.3x > 29.7
Divide both sides by 3.3
3.3x/3.3 > 29.7/3.3
x > 9

Good luck !

Please help, the question is on the picture.

Taya2010 [7]

X^2 + 14x + 17 = -96
x^2 + 14x + 113 = 0
x^2 + 14x + 49 + 64 = 0
(x + 7)^2 = -64
x + 7 = sqrt(-64) = + or - 8i
x = -7 + or - 8i
