The midpoint formula is (x1+x2/2, y1+y2/2
so you would do (-5+14)/2=4.5. (-2+12)/2=5
(4.5, 5)

For a moving object, the force is acting on the object varies directly with the object’s acceleration. When a force of 9 N acts
svetlana [45]

Answer:

12 Newtons

Step-by-step explanation:

We can use Newton’s Second Law to find the mass first.

F = ma

9 = 3m

mass = 3

Substitute this into the second equation.

F = ma

F = 3(4)

F = 12N

Hope this helps! :D

Garrett works for a company that builds parking lots the graph shows the area of a parking lot based on the length of one side.
dedylja [7]

Answer: Option D.

Step-by-step explanation:

this is a quadratic equation of the form:

y = ax^2 + bx + c

First, things you must see.

The graph opens up, so we must have thata a is greater than zero, so we can discard the first option.

Second, we can see that the vertex is located in x ≈ 70

The vertex of a quadratic equation is: x = -b/2a

so we have:

70 = -b/2a

let's try our options and see if we can discard other:

B:

-b/2a = 69.9/2 = 34.95

we can discard this option.

C:

-b/2a = 78/2 = 39 we can discard this option.

D:

-b/2a = 69.9/2*0.5 = 69.9

This is the only one that fits, so this is the correct option.

A region R in the xy-plane is given. Find equations for a transformation T that maps a rectangular region S in the uv-plane onto
muminat

Answer:

x = u\cos(v) , y = u \sin(v)

Step-by-step explanation:

For that transformation you just have to use polar coordinates, notice that when you use polar coordinates the radius is constant when the angles varies and the angle is constant when the radius varies. Therefore your transformation would be just

x = u\cos(v) , y = u \sin(v).

What is the slope of the line that contains the points (2, -6) and (-3, 1)?
Radda [10]

Answer:

The slope is m=-\frac{7}{5}

Step-by-step explanation:

The slope of the line passing through (x_1,y_1) and (x_2,y_2) is given by the formula;

m=\frac{y_2-y_1}{x_2-x_1}

The given line contains;the points (2, -6) and (-3, 1).

m=\frac{1--6}{-3-2}

m=\frac{1+6}{-3-2}

m=\frac{7}{-5}

The slope is m=-\frac{7}{5}
