In the standard (x,y) coordinate plane, point A has coordinates (−4,0) and point B has coordinates (0,−8). What are the coordinates of the midpoint of AB? How can i solve this ?

Answers

Answer 1

Answer: $A (-4,0), \ B (0,-8) \n \nThe \ midpoint \ M \ of \ the \ line \ segment \ joining \ the \ points \n \n (x _(1), y _(1)) \ and \ (x _(2), \ y _(2)) \ is : \n \n M=((x_(1)+x_(2))/(2);(y_(1)+y_(2))/(2))$

$M=((-4+0)/(2);((0+(-8))/(2))\n \n M=((-4)/(2); (-8)/(2))\n \nM=(-2;-4)$

Your new job guarantees you an eight percent raise for each year with the company. If your initial salary is $42,200, write an equation to model your salary after t years

Answers

initial salary is $42,200

eight percent raise for each year = 1.08

salary after t years

equation :

Y(t) = $42,200 x (1.08)^t

$42,000
× 0.08
$3,360
+42,000
= $45,360

The length of a rectangle is represented by the function L(x) = 5x. The width of that same rectangle is represented by the function W(x) = 2x2 − 4x + 13. Which of the following shows the area of the rectangle in terms of x?(L ⋅ W)(x) = 10x3 − 4x + 13
(L ⋅ W)(x) = 10x3 − 20x2 + 65x
(L + W)(x) = 2x2 + 1x + 13
(L + W)(x) = 2x2 − 9x + 13

Answers

A= l x w
5x * 2x^2 - 4x + 13
10x^3 - 20x^2 + 65x

The function that represents the area of the rectangle is: B. (L × W)(x) = 10x³ - 20x² + 65x.

What is the Area of a Rectangle?

Area of a rectangle = (length × width)

Applying the area of a rectangle formula, the area of the rectangle would be:

(L × W)(x) = 5x(2x² - 4x + 13)

Apply the distributive property

(L × W)(x) = 10x³ - 20x² + 65x

The area in terms of x is: (L × W)(x) = 10x³ - 20x² + 65x.

HELP PLEASE ASAP!! Which relation is a function?

Answers

Answer:

The one on the bottom left.

Step-by-step explanation:

To find out which one is a function, we would use the vertical line test. First you create a vertical line with your finger, pencil, or another object. If there are two dots that pass a vertical line, it would not be a function. Only one dot can cross the vertical line for it to be a function.

How do i find the perimeter of the triangle with vertices at three points (0,1),(2,1), and (0,3)?

Answers

The perimeter is the sum of the lengths of the three sides.

To find the perimeter, you need to find the lengths of the three sides.

For each side, you are given the points at the two ends.You need to find the distance between those two points.

Once you have all thee distances, add them up.

That's how.

Well I'm not just going to tell you the answer, you need to "experience" how you do it. Basically you use the distance formula, which I'll show you in a bit, to fine the length of the segments. Then you just add them up.
