Answer:
The area is changing at 2 m²/d.
Step-by-step explanation:
The area of a rectangle is given by:
Where:
l is the length
w is the width
We have that the length is increasing at a rate:
And the width is decreasing at a rate:
The change in the rectangle's area is the following:
When the length is 8 meters and the width is 18 meters we have:
Therefore, the area is changing at 2 m² per day.
I hope it helps you!
You have the maximum height happens at 5 seconds.
Replace t with 5 and solve for h(t):
h(5) = -0.2(5)^2 + 2(5)
h(5) = -0.2(25) + 10
h(5) = -5+10
h(5) = 5
The maximum height is 5 feet.
Answer:
The volume of the prism is 360 cm^3.
Step-by-step explanation:
The rectangular prism is a three dimensional figure formed by six rectangular faces. It's volume is given by the product of it's three dimensions. The calculation for the volume of this prism is shown bellow:
volume = width*height*length
volume = 9*10*4
volume = 360 cm^3
The volume of the prism is 360 cm^3.
Since it’s parallel, it should still be y2-y1/x2-x1 but answer is -12/3 which equals -4
