A) what is average rate of change of f(x) over the interval from x=5 to x=9? (table shows values of f(x). graph shows function o

SVETLANKA909090 [29]

Answer:

See below for answers and explanations

Step-by-step explanation:

Part A

The average rate of change of a function over the interval $[a,b]$ is equal to $\frac{f(b)-f(a)}{b-a}$ , hence:

$\frac{f(b)-f(a)}{b-a}\\\\\frac{f(9)-f(5)}{9-5}\\\\\frac{14-(-4)}{9-5}\\ \\\frac{14+4}{4}\\ \\\frac{18}{4}\\ \\\frac{9}{2}$

Therefore, the average rate of change of $f(x)$ over the interval $[5,9]$ is $\frac{9}{2}$ .

Part B

Do the same thing as in Part A:

$\frac{f(b)-f(a)}{b-a}\\ \\\frac{f(1)-f(0.25)}{1-0.25}\\ \\\frac{2-5}{0.75}\\ \\\frac{-3}{0.75}\\ \\-4$

Therefore, the average rate of change of $g(x)$ over the interval $[0.25,1]$ is $-4$ .

Part C

To interpret our answer from Part B in terms of the real world it represents, we say that between 0.25 seconds and 1 second, the ball falls at a rate of 4 feet per second (since our average rate of change is negative).

Which value of $y$ makes the equation $3y+8=7y+11$ true?

valentinak56 [21]

value of y which satisfies equation $3y+8=7y+11$ is $y= \frac{-3}{4}$ .

Step-by-step explanation:

We have , 3y+8=7y+11 . We need to find which value of y satisfies this equation 3y+8=7y+11 :

$3y+8=7y+11$

⇒ $3y+8=7y+11$

⇒ $(3y+8)-3y=(7y+11)-3y$

⇒ $8=4y+11$

⇒ $4y+11 = 8$

⇒ $(4y+11)-11 = 8-11$

⇒ $4y= -3$

⇒ $\frac{4}{4}y= \frac{-3}{4}$

⇒ $y= \frac{-3}{4}$

Therefore, value of y which satisfies equation $3y+8=7y+11$ is $y= \frac{-3}{4}$ .
