base 16y^2
height y^2 + y + 3
V = b*h
V = 16y^2(y^2 + y + 3)
V = 16y^4 + 16y^3 + 48y^2

a falling object travels a distance given by the formula d=5t + 16t^2 ft, where t is measured in seconds. how long will it take
zzz [4022]

It is provided that

d=5t+16t^{2}

We need to determine t when d equals 74

Thus, 74=5t+16t^{2} or

16t^{2}+5t-74 = 0

16t^{2}+37t-32t-74 = 0

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.

PIT_PIT [3919]

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)

Terrence walks at a pace of 2 mi/h to the theater and watches a movie for 2 hours and 15 min he rides a bus back home at 40 mi/h
zzz [4022]

Solution:

Let x be the distance in miles from the house to the theater.

Total time taken for the trip =3.5-2.25=1.25 Hr

Then average speed =\frac{Distance}{Time}= \frac{2x}{1.25}\\

Terrence walks at a speed of 2 miles per hour to the theater and returns home at 40 miles per hour.

Thus, Average Speed =\frac{2+40}{2}= 21\\ mi/hr

Both average speeds must be equivalent. Hence, we can express this as:

\frac{2x}{1.25}=21\\
\\
2x=1.25*21\\
\\
x=13.125\\

Consequently, the distance from home is 13.125 miles.

Identify the equation of the circle that has its center at (-27, 120) and passes through the origin.
zzz [4022]

The equation representing the circle centered at (-27, 120) that passes through the origin is:

(x + 27)^2 + (y - 120)^2 = 15129

Solution:

The general equation of a circle is expressed as:

(x-a)^2+(y-b)^2=r^2

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

(0 + 27)^2 + (0 - 120)^2 = r^2\\\\729 + 14400 = r^2\\\\r^2 = 15129

Input r^2 = 15129 and (a, b) = (-27, 120) into the equation

(x + 27)^2 + (y - 120)^2 = 15129

Hence, the equation characterizing the circle is determined
