Step-by-step explanation:
f(3) = 48
f(3)-f(4) = 3*3^2
f(4) = 21
f(4)-f(5) = 3*4^2
f(5) = -27
4:44 pm but I might be wrong.
Answer: What is your question
Step-by-step explanation:
Answer:
8 hours
Step-by-step explanation:
Joe's data shows the minimum to be 4 hours after his arrival at the beach. The time between maximum and minimum is half a period. (The other half brings the function back to its maximum.) If half a period is 4 hours, the whole period is 8 hours.
Answer: 0.4x + 0.1
Step-by-step explanation: Distribution.
0.5(x+0.1)-0.1(x-0.5)
0.5 times x = 0.5x
0.5 times 0.1 = 0.05
First step: 0.5x + 0.05
Distribute next part
-0.1 times x= -0.1x
-0.1 times -0.5 = 0.05
-0.1x + 0.05
Put together: 0.5x + 0.05 -0.1x + 0.05
Combine like terms:
0.5x -0.1x = 0.4x
0.05 + 0.05 = .1
Answer: 0.4x + 0.1
