The speed of the ball is
ds/dt = 32t
At t =1/2 s
ds/dt = 16 ft/s
The distance from the ground
50 - 16(1/2)^2 = 46 ft
The triangles formed are similar
50/46 = (30 + x)/x
x = 345 ft
50 / (50 - s) = (30 + x)/x
Taking the derivative and substituing
ds/dt = 16
and
Solve for dx/dt
60x+80=100x combine like terms
80=100x-60x or 40x divide to get x by itself
80/40=40x/40
20=x

ANSWER
C. Both equations will find the correct solution.
EXPLANATION
It was given in the question that, Asha and Jamal started with 45 plants.
We were told that, they sold some plants and now they have 21 plants left.
Let

represent the number of plants sold.
Then when we add the number of plants sold and the number left, we should get 45.
This implies that,

This is Jamal's equation.
On the other hand, if we subtract the number of plants sold from the total number of plants, we should get 21. Thus,

This is Asha's equation.
The two equations are therefore equivalent.
They will give the same solution.
The correct answer is C.
Answer:
they bisect each other
Step-by-step explanation:
<em>The diagonals of a parallelogram bisect each other</em>.
__
If they are the same length, the parallelogram is a rectangle. If they cross at right angles, it is a rhombus.
