A wheel with radius 1 foot makes 1 revolution in 4 seconds. What is the linear velocity, in feet per second, of a point on the e

Alona [7]

In one revolution of the wheel, a point on the edge travels a distance equal to the circumference of the wheel.

The wheel has radius 1 ft, so its circumference is 2π (1 ft) = 2π ft.

Then the point has a linear speed of

(1/4 rev/s) * (2π ft/rev) = 2π/4 ft/s = π/2 ft/s

Answer:

B. When the peak temperature is 40°C, 72 units of electricity are used on average.

Step-by-step explanation:

We see the relationship is closer to linear in the interval 30 to 40

Approximate points:

(30, 34) and (34, 54)

The slope of the line:

m = (54 - 34)/(34- 30) = 20/4 = 5

The line is:

y - 34 = 5(x - 30)
y = 5x - 116

At x = 40, the value of y would be:

y = 5*40 - 116 = 84

The closet option is B
