Every second, the shark descend 35.75ft. In ten seconds the shark will have gone 10 times deeper. 35.75 times 10 is 357.5.
Answer:
m = 9
Step-by-step explanation:
Using the rules of exponents
= 
×
⇔ 
= 
Then
×
= 243 ← express all values to base 3
×
= 
×
= 
×
= 
=
Since bases on both sides are equal, both 3 , then equate exponents
- 3m - 4 = 5 ( add 4 to both sides )
- 3m = 9 ( divide both sides by - 3 )
m = - 3
Answer:
Skewed right center around varies from 12 to 30. Possible outliers 12, 14, 15, 16.
d(t)=2t^2. [5,9]
The average rate of change is calculated by the formula: d(t2) - d(t1) / t2 - t1
So plug in 5 as t1 and 9 as t2.
d(9) - d(5) / 9 - 5 =
(2×81) - (2×25) / 9 - 5 =
162 - 50 / 4 =
112 / 4 = 28
The average speed is 28 feet.
