Step: 3 and 4

In step 3 you were suppose to add 34 to both sides to cancel it out which should have given you positive 17x=40

Im kinda confused if the problem is 2(10-13)=-34x+60 were did you get 9x and 26x on the left side

Answer:

$2x\sqrt{40x}-2x\sqrt{5}$

Step-by-step explanation:

$2x\sqrt{40x}-2x\sqrt{5}$ is found by first, siplifying the radicals in the parenthesis. $\sqrt{8x^{2} }$ can be simplified as $2x\sqrt{2}$ and $-2\sqrt{x}$ stays the same. Now we have to multiply these two by $\sqrt{5x}$ which then results in $2x\sqrt{40x}-2x\sqrt{5}$

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
