The height of the tree was 56 inches.
We can calculate the percentage of a certain amount by :
Subtracting New - Original / New multiplied by 100
this implies it will be
75 - x / 75 × 100 = 25 %
7500 - 100 x = 1875
this implies 7500 - 1875 = 100 x
5625 = 100 x
Thus , On dividing both sides by 100 we get
56.25 = x
Now on rounding off this number we will get
56 = x
Thus the original height of the corn plant was 56 inches

The equation of the line in slope intercept form is y = - 1 / 2x + 4
<h3>How to write equation in slope intercept form?</h3>
The equation in slope intercept form is represented as follows:
y = mx + b
where
Therefore,
using the points (2, 3)(0, 4)
m = 4 - 3 / 0 - 2 = 1 / -2 = - 1 / 2
Hence,
b = 4
Therefore, the slope intercept equation of the line is as follows:
y = - 1 / 2x + 4
The y-intercept is value of y when x = 0

Answer:
dh/dt = 0.4 m/min
Step-by-step explanation:
The volume of the cone is:
V(c) = (1/3)*r² *h if always h = 3r then r = h/3
The volume of the cone as a function of h will be:
V(h) = (1/3)* (h/3)²*h
V(h) = (1/27)*h³
The increasing rate of the volume is equal to the rate of sand added the:
D(V)/dt = (1/27)*3*h²*dh/dt
D(v) / dt = 10 m³/min
h = 15 m and dh/dt is the rate of increasing of the height
By substitution
10 m³/min = ( 1/9)* 225 * dh/dt (m²)
dh/dt = 90 / 225 m/min
dh/dt = 0.4 m/min
