It is provided that

We need to determine t when d equals 74
Thus,
or


t(16t + 37) - 2(16t + 37) = 0
(t - 2)(16t + 37) = 0
t - 2 = 0 or 16t + 37 = 0
t cannot be negative.
Thus, t equals 2
Therefore, it will require 2 seconds for the object to cover 74 feet.
Answer:
dV(t)/dt = kV(t)
Step-by-step explanation:
The annual change in the car's value, represented by dV(t)/dt, has a proportional relationship with V(t), the car's current value.
dV(t)/dt ∝ V(t)
dV(t)/dt = kV(t)
Solution:
Let x be the distance in miles from the house to the theater.
Total time taken for the trip 
Then average speed 
Terrence walks at a speed of 2 miles per hour to the theater and returns home at 40 miles per hour.
Thus, Average Speed
mi/hr
Both average speeds must be equivalent. Hence, we can express this as:

Consequently, the distance from home is 13.125 miles.
The equation representing the circle centered at (-27, 120) that passes through the origin is:

Solution:
The general equation of a circle is expressed as:

Where,
(a, b) denotes the center of the circle
r signifies the radius
Given the center as (-27, 120)
Thus;
a = -27
b = 120
Considering it intersects the origin, meaning (x, y) = (0, 0)
Substituting (a, b) = (-27, 120) and (x, y) = (0, 0) into the equation

Input
= 15129 and (a, b) = (-27, 120) into the equation

Hence, the equation characterizing the circle is determined
The constant of variation is 5 because 4 multiplied by 5 equals 20.
