Given f(x) =17 -x2 what is the average rate of change in f(x) over the interval [1,5]

Artist 52 [7]

By definition the average rate of change is given by:
 $AVR = \frac{f(x2) - f(x1)}{x2-x1}$
We have the following function:
 $f(x) =17 - x^2$
We evaluate the function for the given interval:
For X = 1:
$f(1) =17 - 1^2$
$f(1) =17 - 1$
$f(1) =16$
For X = 5:
$f(5) =17 - 5^2$
$f(5) =17 - 25$
$f(5) =-8$
Then, replacing values we have:
$AVR = \frac{-8 - 16}{5-1}$
$AVR = \frac{-24}{4}$
$AVR = -6$
Answer:
the average rate of change in f(x) over the interval [1,5] is:
 $AVR = -6$

What is 7.8 × 105 m/h in kilometers per day? A. 3.24 × 1010 km/day B. 3.24 × 108 km/day C. 1.872 × 106 km/day D. 1.872 × 104 km/

damaskus [11]

The comparison may be done by the dimensional analysis and the proper conversion factor. That is,
(7.8 x 10^5 m/h) x (1 km / 1000 m) x (24 h / 1 day) = 18720 km / day
The scientific notation of the answer is 1.872 x 10^4 km/day. Thus, the answer is letter D.

Which statements are true of the given function? Check all that apply.

skad [1K]

9514 1404 393

Answer:

B, E

Step-by-step explanation:

The table tells you that f(0) = 3/2. (0 is found in the x-column; 3/2 is found in the f(x) column.)

You can find f(4) by evaluating the formula.

f(4) = 1/2·4 +3/2 = 4/2 +3/2

f(4) = 7/2 . . . . agrees with last answer choice
