The volume of a rectangular prism (in this case, the pool) is found by multiplying the values of the length, the height, and the width together.
44 * 9 * 8 = 3168
The volume of the pool is 3,168

.
Hope that helped! =)
The amount A resulting from a principal amount P being invested at rate r compounded continuously for time t is given by
... A = P·e^(rt)
FIll in your given values and solve for P.
... 25000 = P·e^(0.0525·12) = P·e^0.63
... P = 25000/e^0.63 ≈ 13314.80 . . . . . divide by the coefficient of P
The amount that must be invested is $13,314.80.
<span> x − 2y = −1 => x = 2y -1
2x + y = −12
2(2y - 1) + y = -12
4y - 2 + y = -12
5y = -10
y = -2
x = 2</span>·(-2) - 1
x = -4 - 1
x = -5
