Answer:
The rate of change in the submarine's elevation is 26.0 feet per second.
Step-by-step explanation:
She begins 151 feet below sea level
Thus, her initial point is y₁ = 151 feet below sea level
i.e. at t₁=0 seconds, y₁ = 151 feet below sea level
After descending for the 3 seconds, she is 229 feet below sea level.
Thus, her second point is y₂ = 229 feet below sea level after 3 seconds
i.e. at t₂=3 seconds, y₂ = 229 feet below sea level
The rate of change is basically the slope. Thus, the rate of change can be obtained by taking the slope.
slope = rate of change = (y₂ - y₁)/(t₂ - t₁)
= (229 - 151) / (3 - 0)
= 78/3
= 26.0
Therefore, the rate of change in the submarine's elevation is 26.0 feet per second.
I'm pretty sure the answer is C. Factorial.
Answer:
5 1/4
Step-by-step explanation:
4/21, This is an improper fraction right now.
Find out how many times 4 goes into 21.
This is 5 times with a remainder of 1.
Put 1 back over 4.
Your answer is 5 1/4.
multiples of 6 = 6, 12, 18, 24 , 30, 36 ,42 , 48
multiples of 8 = 8, 16, 24,32,40,48
24 & 48 are the common multiples
so there is a 2 out of 48 chance which is 2/48 which reduces to 1/24 probability
