Find the average rate of change of each function on the interval specified.

ExtremeBDS [4]

The average rate of change (AROC) of a function f(x) on an interval [a, b] is equal to the slope of the secant line to the graph of f(x) that passes through (a, f(a)) and (b, f(b)), a.k.a. the difference quotient given by

$f_{\mathrm{AROC}[a,b]} = \dfrac{f(b)-f(a)}{b-a}$

So for f(x) = x² on [1, 5], the AROC of f is

$f_{\mathrm{AROC}[1,5]} = \dfrac{5^2-1^2}{5-1} = \dfrac{24}4 = \boxed{6}$

Determine the sum: (14abc2 + 12a2b + 16b2c) + (−3abc2 + 2b2c).

Alenkinab [10]

The answer is 11abc^2 + 12a^2b + 18b^2c because:
14abc^2-3abc^2 is 11abc^2
12a^2b + 0 = 12a^2b
16b^2c +2b^2c = 18b^c

A rocket is shot in the air at an initial velocity of 12 800 miles per hour. If 1 mile is equal to 5 280 feet, then what is the

Natasha_Volkova [10]

Answer:

GIVEN,

Initial velocity of the rocket = 12800miles/hour

1 mile = 5280 feet

Initial velocity of the rocket in miles/second = (12800*5280)/60*60 feet/second = 18773.33333...feet/second.

What is the volume of a cone when the radius is 6 and the height is 13

lidiya [134]

Answer:

<h2>489.84 units³</h2>

Step-by-step explanation:

Given,

Radius ( r ) = 6

Height ( h ) = 13

Volume of cone = ?

Now, Let's find the volume of cone:

$= \pi \: {r}^{2} \frac{h}{3}$

plug the values

$= 3.14 \times {6}^{2} \times \frac{13}{3}$

Evaluate the power

$= 3.14 \times 36 \times \frac{13}{3}$

Calculate

$489.84$ units³

Hope this helps..

Best regards!!
