Answer:
21/8 or 2 5/8
Step-by-step explanation:
9/4 + 3/8
The least common denominator being 8 so you would add the numerators.
18+3/8

Answer:
C.
Another way to write the added percent of something is by putting a 1 to indicate the aditional.
Answer:
Step-by-step explanation:
The highest power of x here is 3, so this is a third degree polynomial. Since the coefficient of the highest power term is +, we know that the graph approximates that of the parent function y = x^3, and that this graph begins in Quadrant III, enters Quadrant I and continues to move upward in Quadrant I.
The area of the rectangle is (2x + 3)(2x - 3) = 4x2 - 9.
Answer:
Step-by-step explanation:
For t in weeks, a reasonable exponential function describing the dept (d) might be ...
d = 10(1.03^t)
Then, after 8 weeks, the depth is predicted to be ...
d = 10(1.03^8) ≈ 12.67 ft ≈ 13 ft
