A function assigns the values. The force that will be required to move the rock is 48 lbs.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

A.) The inverse of the function f(x)=1/x is,

f(x) = 1/x

y = 1/x

x = 1/y

g(x)=1/x

Hence, The inverse of the function f(x)=1/x is g(x)=1/x.

B.) The force that will be required to move the rock using the momentum,

9ft × 80lbs = 15 ft × F

F = 48 lbs

Hence, The force that will be required to move the rock is 48 lbs.

Write an equation in point-slope form for the line that satisfies the given set slope of 4/5, passes through (10,-30

hodyreva [135]

Answer:

y + 30 = 4/5(x - 10)

Step-by-step explanation:

Given the slope, 4/5, and point (10, -30):

We can plug these values into the point-slope form:

y - y1 = m(x - x1)

Let (x1, y1) = (10, -30)

and m = 4/5

y - (-30) = 4/5(x - 10)

y + 30 = 4/5(x - 10)

Therefore, the point-slope form is y + 30 = 4/5(x - 10)

what is the rate of change for the linear relationship modeled in the table? x y −1 10 1 9 3 8 5 7 -1/2 0 1/2 2

Vesnalui [34]

Answer:

Rate of change for the linear relationship modeled is $\dfrac{-1}{2}$

Step-by-step explanation:

As the there is a linear relationship in the points, so all these points will be on a single straight line. Hence the slope will be same throughout all the points.

We know that, the slope of the line joining (x₁, y₁) and (x₂, y₂) is,

$m=\dfrac{y_2-y_1}{x_2-x_1}$

Putting the points as (-1, 10) and (1, 9), we get

$m=\dfrac{9-10}{1-(-1)}$

$=\dfrac{9-10}{1+1}$

$=\dfrac{-1}{2}$

Rate of change is the slope of the line joining all these points.
