What is the average rate of change of the function f(x)=20(14)xf(x)=20(14)x from x = 1 to x = 2? Enter your answer, as a decimal

Advocard [28]

The average rate of a function f(x) over an interval x = a and x = b is given by:

$Average \ Rate \ of \ Change= \frac{f(b)-f(a)}{b-a}$

Given the function

$f(x)=20(14)^x$

The average rate of change from x = 1 to x = 2 is given by:

$\frac{f(2)-f(1)}{2-1} = \frac{20(14)^2-20(14)^1}{1} \\ \\ =20(196-14)=20(182)=3,640$

-x+4>-3x-4
+x +x
---------------------
4>-3x-4
+4 +4
----------------
8>-3x
/3 /3
----------------
8>2.7
x=2.7

Simplify the expression 4x^3/28x^4

KIM [24]

1/7x

Factorize the numbers (4 and 28) as they have a common factor of 4 so you can simplify it to 1/7. Cancel out the 3 in the x (numerator) from the denominator and you will have x^1 remaining in the denominator. That is also the same as x, therefore making it 1/(7x)

67+65+ what gives me 180

Serga [27]

Answer:

48.

Step-by-step explanation:

To find the missing number write out the equation :

67 + 65 + ? = 180.

67 + 65 = 132

To find out how much more we need you can minus 132 from 180.

180 - 132 = 48.

Plug it in to see if it works.

67 + 65 + 48 does equal 180.

Hope this helps,

Davinia.
