Anastaziya [24]

Answer:

11/24

Step-by-step explanation:

First find the common denominators of each fraction:

The common denominator of each fraction is 24

1/8 multiplied by 3 is 3/24
1/6 multiplied by 4 is 4/24

1/4 multiplied my 6 is 6/24

add these fractions up

3/24 + 4/24 + 6/24 = 13/24

subtract 24/24 - 13/24 = 11/24

Please help me with this question

Vlad1618 [11]

Answer:

Step-by-step explanation:

a1 = 3;

a2 = 2(a1 - 2 ) = 2(3-2) = 2

a2 = 2

a3 = 2(a2-2) = 2(2-2) = 0

a3=0

a4 = 2(a3-2) = 2(0-2) = -4

a4 = -4

a5 = 2(a4 - 2) = 2(-4-2) = -12

a5 = -12

For f(x)=0.01(2)power of x, find the average rate of change from x=3 to x=8

sineoko [7]

$\bf slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ f(x_2)}}-{{ f(x_1)}}}{{{ x_2}}-{{ x_1}}}\impliedby 
\begin{array}{llll}
average\ rate\\
of\ change
\end{array}\\\\
-------------------------------\\\\
f(x)= 0.01(2)^x \qquad 
\begin{cases}
x_1=3\\
x_2=8
\end{cases}\implies \cfrac{f(8)-f(3)}{8-3}
\\\\\\
\cfrac{0.01(2)^8-0.01(2)^3}{8-3}$
