The midpoint of AB is (-4,7) and point A is

1 answer:

4 0

Ok so, this one is a confusing one for me but what I recomend is going on a website call desmos , they have a graphing area there and use y=-4x-7 if I’m right, I do not know so don’t trust me on this

What is a rational number that's not an integer

vlabodo [156]

A rational number is any number that can represented as a fraction of two integers (when the denominator isn't 0). As decimals, rational numbers can be either terminating or repeating.

All integers are rational numbers because they can be expressed as x/1.

An example of a rational number that isn't an integer is 2/3.

Find x+y. <br><br><br><br> Please help<br> Please help

marshall27 [118]

Answer: x = 12, y = 50

Step-by-step explanation: 2y-5 and 95 are vertical angles and vertical angles are always congruent (equal). So, 2y - 5 = 95. 2y = 100. y = 50. Solving for x is slightly more difficult. 3x and 144 are linear pairs and linear pairs are adjacent and equal 180° because a straight line is 180°. So 3x + 144 = 180. 3x = 36. x = 12.

Add 3x to both sides

-3x+10=3x-8
+3x +3x
10=6x-8
+ 8 +8

18=6x

Sharon is jumping from an 18-foot diving board with an initial upward velocity of 4 ft/s. when sharon jumps, megan throws a beac

Alinara [238K]

It will take 1.08 seconds for the ball to reach Sharon after she jumps if the upward velocity of the ball is 16 ft/s from a height of 5 feet option third is correct.

<h3>What is the equation of motion?</h3>

It is defined as the equation by which we can find the motion of a physical particle with respect to time. It is the representation of physical entity movement in a mathematical function.

We have:

The height of the Sharon from the diving board = 18 feet

The initial upward velocity of the Sharon = 4 ft/s

The height of the Megan from the ground = 5 feet

The initial upward velocity of the beach ball = 16 ft/s

We know the equation of motion is given by:

$\rm h(t) = x + ut+\frac{1}{2} gt^2$

Put x = 18 feet and u = 4 ft/s in the above equation, we get:

$\rm h(t) = 18 + 4t+\frac{1}{2} \times9.8t^2$ ....(1) [g = 9.8 m/s²]

Put x = 5 feet and u = 16 ft/s in the equation of motion, we get:

$\rm h(t) = 5 + 16t+\frac{1}{2} \times9.8t^2$ ....(2)

Equate the equation (1) and equation (2), we get

$\rm 18 + 4t+\frac{1}{2} \times9.8t^2= 5 + 16t+\frac{1}{2} \times9.8t^2\\$

18 + 4t = 5 + 16t

12t = 13

t = 1.08 seconds

Thus, it will take 1.08 seconds for the ball to reach Sharon after she jumps if the upward velocity of the ball is 16 ft/s from a height of 5 feet.
