Mathematics

Komok [63]3 years ago

Part A:

Expression: 21 = 8h + 179

Part B:

21 = 8h + 179

h = - 19

Move 179 to the other side by subtracting 179 from both sides.

21 - 179 = -158

-158 = 8h

Then, divide both sides by 8 to get the feet descended per hour.

-158/8 = -19

h = -19

Therefore, Luther and Nicole descend approximately 19 feet per hour.

Consider the graph of the quadratic function. Which interval on the x-axis has a negative rate of change?
Gre4nikov [31]

The average rate of change is defined as:

AVR = \frac{f(x2)-f(x1)}{x2-x1}

For AVR to be negative, it must comply with:

x2 - x1> 0

f (x2)

Therefore, we observe that the interval that fulfills these conditions is the whole interval to the right of the parabola.

Among the options given, this interval is:

1 to 2.5

Answer:

An interval on the x-axis that has a negative rate of change is:

D. 1 to 2.5
