Answer:
A. Plant 1 is growing at a faster rate than Plant 2.
Step-by-step explanation:
The slope (m) or rate of growth in Plant 1 is;
m = Change in y ÷ change in x
m = = 2
The linear equation of growth in Plant 1 is;
= 2
y = 2x + 1.5
The equation of growth in Plant 2 is; y = 1.5x + 3 (slope of 1.5)
Since the slope in growth of Plant 1 is greater than that in Plant 2, it implies then that Plant 1 is growing at a faster rate than Plant 2.
Given:
The area of the given sphere = 36π in²
To find the volume of the given sphere.
We need to find the radius first.
Formula
- The area of a sphere
- The volume of the sphere
where, r be the radius of the sphere.
Now,
According to the problem,
or, [ Eliminating π from both the side]
or,
or,
or,
So,
The radius of the sphere is 3 inches
Therefore,
The volume of the sphere is
or,
Hence,
The volume of the sphere is 36π cube inches.
Answer:
80 cu^3
Step-by-step explanation:
The width is 5 and the height is 4 so,
5 x 4 = 20
the length is 4 so,
20 x 4 = 80
I got 83! hope this helps
We need to find distance they travel as a function of time. This simply means that x is the function of time. The destination is 120 miles away, this is irrelevant for the question that is currently being asked. However, we know that they have already travelled 20 miles and are going 50 miles and hour. So lets plug in what we have.
50 is our rate of change, so we match that with the x.
20 is our constant, the distance already travelled.
This means our function is:
f(x) = 50x + 20
This means our answer is D) f(x) = 50x + 20
Lets also plug in 120 to solve how much further they need to travel before arriving.
120 is our f(x) as it is the final distance travelled.
120 = 50x + 20
120-20 = 50x
100 = 50x
100/50 = x
2 = x
This means that they need to travel 2 hours in addition to the 20 miles they have already gone.
I hope I've helped! :)
