The answer is 4x
Answer:
Step-by-step explanation:
Snorkel, mask, and flippers Slope: 2 (so in the equation, it would look like 2x).
Snorkel, mask, and flippers Y-intercept: 10 (12 - 2 = 10, which is 0 hours, possibly the initial amount)
Snorkel, mask, and flippers Slope intercept form: y = 2x + 10

Answer:
6.2 feet
Step-by-step explanation:
The mnemonic SOA CAH TOA reminds you of the relationship between angles and sides of a right triangle. Here, we have the side opposite the 58° angle, and we want to know the side adjacent. The relevant relation is ...
Tan = Opposite/Adjacent
tan(58°) = (10 feet)/x
x = (10 feet)/tan(58°) ≈ 6.249 feet
The length of the shadow is about 6.2 feet.
