Answer:

60 feet

Step-by-step explanation:

Pentagon = 5 sides

We need to find the perimeter of the pentagon and we know that one side is 12 feet so,

1 side = 12 feet

( Multiply by 5 to get 5 sides )

5 sides = 60 feet

Kipish [7]

Answer:z = $2286.5

y = $2713.5

Step-by-step explanation:

Let z represent the amount of money invested at the rate of 7%.

Let y represent the amount of money invested at the rate of 9%.

Mr. Jones has part of his $5,000 savings in an account that earned 7% interest and the rest in an account that earned 9% interest.. This means that

z + y = 5000

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time

Considering the investment at the rate of 7%,

P = x

R = 7

T = 1

I = (z × 7 × 1)/100 = 0.07z

Considering the investment at the rate of 9%,

P = y

R = 9

T = 1

I = (y × 9 × 1)/100 = 0.09y

if his annual income from the total investment was 404.27, it means

0.07z + 0.09y = 404.27 - - - - - -1

Substituting z = 5000 - y into equation 1, it becomes

0.07(5000 - y) + 0.09y = 404.27

350 - 0.07y + 0.09y = 404.27

- 0.07y + 0.09y = 404.27 - 350

0.02y = 54.27

y = 54.27/0.02 = $2713.5

Substituting y = 2713.5 into z = 5000 - y, it becomes

z = 5000 - 2713.5 = $2286.5

$y=12*3^{x}$

plugging x=-2 in the given equation we get

$y=12*3^{-2}$

=12/3²

=12/9

=4/3

Find the equation of a circle with the same center as the circle in the graph above and that passes through a point 2 units away

Ira Lisetskai [31]

The equation of a circle with center at (a, b) and radius, r, is given by
$(x-a)^2+(y-b)^2=r^2$

The given circle in the graph has the center at (0, 2) with the radius of 1 units.

<span>A circle with the same center as the circle in the graph and that passes through a point 2 units away from the given circle has its center at (0, 2) and a radius of 3 units.

Thus the equation of the circle is given by
$(x-0)^2+(y-2)^2=3^2 \\ \\ x^2+y^2-4y+4=9 \\ \\ x^2+y^2-4y-5=0$ </span>

3x^2 + 2x - 6 if x = -2

=3(-2)^2 + 2(-2) - 6
=12 - 4 - 6
= 2

5x^2 + 6x - 2 if x = -2

=5(-2)^2 + 6(-2) - 2
=20 - 12 - 2
= 6

-2x^3 + 2x^2 if x = 2

= -2(2)^3 + 2(2)^2
= -16 + 8
= -8
