The difference could be that it is more difficult than multiplying improper/regular fractions. Multiplying improper/regular fractions makes it much easier by just multiplying the numerator and denominator of the fractions while mixed fractions require more steps. After multiplying the fractions you just need to simplify.
Answer:
x² + (y + 8)² = 81
Step-by-step explanation:
Centre (h,k) = (0,-8)
radius (r) = 9
(x - h)² + (y - k)² = r²
(x - 0)² + (y + 8)² = 9²
x² + (y + 8)² = 81
Answer:
sorry I don't know
Step-by-step explanation:
To determine the number of years it would take for money to reach a certain amount, we need to know the type of interest of the problem. As a general rule, when it is not stated clearly in the problem, we assume that it is a simple interest problem since it is the basic type of interest. We use the formula for the future value for simple interest rate. It is expressed as:
F = P (1 + i )^n where F is the future value, P is the present value, i is the interest rate, and n is the number of years
We calculate as follows:
5500 = 400 (1 + .08 )^n
55/4 = (1 + .08)^n
n = 34.06 years
C
.) The - 3 at the end of the function means the function is shifted down 3 units. This also shifts the asymptote down 3 units.
