Answer:

- 121

Step-by-step explanation:

The recursive formula allows us to find the next term in a sequence from the previous term, thus

f(1) = - 3f(0) + 2 = - 3 × 5 + 2 = - 15 + 2 = - 13

f(2) = - 3f(1) = - 3 × - 13 + 2 = 39 + 2 = 41

f(3) = - 3f(2) + 2 = - 3 × 41 + 2 = - 123 + 2 = - 121

Find the perimeter of a rectangle of A=2.76x10^12cm^2 and one side is 4.6x10^5
levacccp [35]

Answer:

1.292 x 10^7 cm^2

Step-by-step explanation:

Since the area of a rectangle is A = L x W and you are given the area and one side, you can rearrange this equation to solve for the other:

L=\frac{A}{W}\\L=\frac{2.76 \times 10^{12}}{4.6 \times 10^5}\\L = 6 \times 10^6

Therefore the length of the other side is 6 x 10^6.

The perimeter of a rectangle is P = 2L + 2W. We can solve that now that we have the length of the sides:

P = 2(6 \times 10^6) + 2(4.6 \times 10^5)\\P = 1.292 \times 10^7

Shade 12 squares on the 4-by-10 grid. <br><br>What percent to is shaded?
denis-greek [22]

On a 10 by 4 grid, there would be 40 squares. If you were to shade 12 of those squares, it can be shown as the fraction:

\frac{12}{40}

12/40 = 0.3

to get a percentage, we would have to multiply by 100

30% is to be shaded
