Answer:
52 degrees
Step-by-step explanation:
The 38 degree angle and the angle marked with a question mark are complimentary, which means they add up to 90 degrees. Knowing this, subtract 38 from 90 to find the mystery angle.

Answer:
h(0) = 1.2
Step-by-step explanation:
The y-intercept is h(0). When x=0, the exponential term evaluates to 1, so the y-intercept is the multiplier of the exponential term.
h(0) = 1.2 . . . the y-intercept
Answer:
44,286
Step-by-step explanation:
The rule is multiplying by -3.
The sequence goes -3, 9, -27, 81, -243, 729, -2187, 6561, -19683, 59049
Add all of those up and you get 44,286
Answer:
Part A is 34
Part B is 2
Step-by-step explanation:
This question did provide some clues to answer this question. Every week, the area covered by the algae is multiplied by 2^1.
To find the area cover increase by the algae per day, the exponent should be divided by 7 since there are 7 days in a week. Hence, every day, the area covered by the algae multiplies by 2^(1/7). In other words, 1 day after the algae was spotted, the area is 12.5 * 2^(1/7), which answers part B.
10 days after the algae was spotted, the area covered by the algae is 12.5 * 2^[(1/7)*10] = 33.6475... , which rounds up to 34 and answers part A.
