Answer:
7. -
a. 3.5 or 7/2 hours
b. 24.5
c. After 7 hours (and at the beginning when t=0)
8. -
a. 4 seconds
b. 1 second
c. 54 meters
Step-by-step explanation:
7. M(t)=-2t^2+14t
M’(t)=-4t+14
a)
-4t+14=0
4t=14
2t=7
t=7/2
b) M(7/2)=24.5
c)
M(t)=0
-2t^2+14t=0
t^2-7t=0
t(t-7)=0
t=0, 7
8.
a)
h(t)=0
-6t^2+12t+48=0
t^2-2t-8=0
(t-4)(t+2)=0
t=-2, 4
t=4
b)
h(t)=-6t^2+12t+48
h’(t)=-12t+12
h’(t)=0
-12t+12=0
12t=12
t=1
c) h(1)=54

Slope = 25/-5
Slope = -5
Answer:
The Humming bee need to eat 0.0028 ounces of food each day.
Step-by-step explanation:
Given:
Weight of the humming bee = 0.0056 ounces
We need to find amount of food humming bee should eat each day to survive.
Solution:
Now given that:
They have to eat half their body weight every day to survive.
So we can say that;
Amount of food humming bee needs to eat is half of the weight of the humming bee.
framing in equation form we get;
Amount of food humming bee needs to eat = 
Hence The Humming bee need to eat 0.0028 ounces of food each day.
Answer:
Area = 70 Perimeter = 50
Step-by-step explanation:
I will begin with area. I can find the area of each figure, then add the areas.
3 • 18 = 54
4 • 4 = 16
Area = 70
For perimeter, I will add the given lengths.
3 + 18 + 7 + 4 + 4 + 14
Perimeter = 50
