Answer:

D.) All integers from 0 to 30, inclusive.

Step-by-step explanation:

If Rebecca has 30 paintings to sell and x is the domain, then any integer from 0-30 inclusive is your answer. It isn't sure that Rebecca will sell a painting, she can't sell more than she has, and she can't sell parts of a painting.

The function f(t)=-16 + 100 models the height of a ball, in feet, dropped from a 100-foot rooftop at time t, in seconds.
Mazyrski [523]

Using it's concept, it is found that the average rate of change of the function during the interval from 0 to 2 seconds is given by:

B. -32 ft/s; the average change in altitude of the ball each second over that interval.

<h3>What is the average rate of change of a function?</h3>

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

r = \frac{f(b) - f(a)}{b - a}

In this problem, the function is given by:

f(t) = -16t² + 100.

The outputs are given as follows:

  • f(0) = -16(0)² + 100 = 100.
  • f(0) = -16(2)² + 100 = 36.

Hence the average rate of change is given by:

r = (36 - 100)/(2 - 0) = -32 ft/s.

And the correct option is:

B. -32 ft/s; the average change in altitude of the ball each second over that interval.

What is the equation of the line with an x-intercept of -2 and a y-intercept of 1?
vaieri [72.5K]

Answer:

the desired line is y = (1/2)x + 1

Step-by-step explanation:

Write these two points as (0, 1) and (-2, 0).

Now, as we go from (-2, 0) to (0, 1), x increases by 2 and y increases by 1.  Thus, the slope, m, of the desired line is m = rise / run = 1 / 2.

Then the desired line is y = (1/2)x + 1 (since b is already given as (0, 1) )
