K/1.5 = 3
Multiply both sides by 1.5
k(1.5/1.5)=3(1.5)
k(1)=4.5
k=4.5

Answer:

incorrect
correct
incorrect

Step-by-step explanation:

A + B = (-4x^2 +2x -5) +(3x^2 +6) = x^2(-4+3) +x(2) +(-5+6) = -x^2 +2x +1

The given sum is Incorrect.

A - C = (-4x^2 +2x -5) -(-5x -4) = -4x^2 +x(2+5) +(-5+4) = -4x^2 +7x -1

The given difference is Correct.

B + C = (3x^2 +6) +(-5x -4) = 3x^2 -6x +2

The given sum is Incorrect.

Answer:

The length of the hypotenuse is 26 inches

Step-by-step explanation:

The leg(brace) attached to the wall is 10 inches

Perpendicular = 10 inches

Your surfboard sits on a leg that is 24 inches.

Base = 24 inches

Formula : $Hypotenuse^2 = Perpendicular^2 +Base^2$

$Hypotenuse^2 = 10^2+24^2$

$Hypotenuse = \sqrt{10^2+24^2}$

Hypotenuse = 26

Hence the length of the hypotenuse is 26 inches

The average rate of change, of the function, between the intervals, x = 2 to x = 6 is: 180.

<h3>What is the Average Rate of Change of a Function?</h3>

Average rate of change = $\frac{f(b) - f(a)}{b - a}$ .

Given the function, $f(x)= 3^x + 25$ ,

The average rate of change using the intervals of, x = 2 to x = 6 would be solved as shown below:

a = 2

b = 6

f(a) = $f(2)= 3^2 + 25$ = 34

f(b) = $f(6)= 3^6 + 25$ = 754

Average rate of change = $\frac{754 - 34}{6 - 2} = \frac{720}{4}$

Average rate of change = 180

Therefore, the average rate of change, of the function, between the intervals, x = 2 to x = 6 is: 180.
