Calculate the average rate of change of the function f(x) = 3x2 over the interval 1 ≤ x ≤ 5.
RideAnS [48]

Answer:

18

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

here [ a, b ] = [ 1, 5 ]

f(b) = f(5) = 3 × 5² = 75

f(a) = f(1) = 3 × 1² = 3, hence

average rate of change = \frac{75-3}{5-1} = \frac{72}{4} = 18

Solve for x please help
Fed [463]

Answer:

x = 5

Step-by-step explanation:

By remote exterior angle theorem:

(6 + 25x) \degree = (18x - 3)\degree  + 44\degree  \\ 6 + 25x = 18x - 3 + 44 \\ 25x - 18x = 41 - 6 \\ 7x = 35 \\ x =  \frac{35}{7}  \\ \huge \red{ \boxed{ x = 5}}

Gwar [14]

Step-by-step explanation:

x = number of cans.

790 total cans and bottles.

790 - x = number of bottles.

y = weight of the cans and bottles in ounces.

y = 14x + 70×(790 - x) = 14x + 55300 - 70x = 55300 - 56x

Please answer both questions.
mario62 [17]

Answer:

1) (x-6)^2=49

2) C

Step-by-step explanation:

Subtract 12 x and you get

-x^2-12x+13=0

You will be left with, after making a perfect square

(x-6)^2=49

To get rid of the squared/2nd power, add plus or minus to the opposite side and square root both sides. You will be left with

x-6=plus or minus 7

Your answer comes out to the to problem. Setting both to 0, you get -13, and 1. -6 plus 7 is 1, and -6 plus a -7 is -13.
