Answer 1

Answer:

  A. horizontal velocity is constant at 25 m/s in every interval

  B. downward velocity increases by 9.8 m/s each second, to 19.6 m/s, 29.4 m/s, 39.2 m/s, 49.0 m/s

Step-by-step explanation:

A.

Since the ball is not rocket-powered, it has no acceleration in the horizontal direction. (We ignore slowing due to air friction.) The horizontal velocity remains constant at 25 m/s.

__

B.

The vertical acceleration is given as 9.8 m/s² in the downward direction. That is, each second the ball is in motion, its velocity downward increases by 9.8 m/s. The table can be filled with ...

  t = 2 s, v = -19.6 m/s

  t = 3 s, v = -29.4 m/s

  t = 4 s, v = -39.2 m/s

  t = 5 s, v = -49.0 m/s

__

The sign is negative because the direction is downward. Positive is up.

The perimeter of a triangular window is 141 inches. The ratio of the side lengths of the window is 11:18:18. What are the side lengths of the window?

Answers

The perimeter of a triangular window is the sum of its side lengths

The side lengths of the window are 33 inches, and 54 inches

How to determine the side lengths?

The ratio is given as:

Ratio = 11: 18 : 18

Rewrite as:

Ratio = 11x: 18x : 18x

Express as sum

Sum = 11x + 18x + 18x

Sum = 47x

The perimeter is 141 inches.

So, we have:

47x = 141

Divide both sides by 47

x = 3

Recall that:

Ratio = 11x: 18x : 18x

So, we have:

Ratio = 11*3: 18*3 : 18* 3

Ratio = 33: 54 : 54

Hence, the side lengths of the window are 33 inches, and 54 inches

The following table contains the first 5 terms of an infinite arithmetic sequence. What is the 7th term?

Answers

f(n) is an arithmetic sequence, so the difference between any two consecutive terms is the same. For instance,

f(2) - f(1) = -0.6 - 0.7 = -1.3

so for all natural numbers n, we should have

f(n) - f(n - 1) = -1.3

Then

f(6) - f(5) = -1.3   ⇒   f(6) = -4.5 - 1.3 = -5.8

f(7) - f(6) = -1.3   ⇒   f(7) = -5.8 - 1.3 = -7.1

The cylinder that has a diameter and height of 6 feet and 2 feet respectively has a volume of 56.5 ft³

Volume of a cylinder

volume of a cylinder = πr²h

where

h = heightr = radius

Therefore,

radius = 6 / 2 = 3 feet

height = 2 feet

volume of the cylinder = 3.14 × 3² × 2

Answer:

it is impossible

Step-by-step explanation:

all shapes need to have all angles to add up to 180 but this triangle adds up to 170

You can make no triangle. It is impossible to draw a triangle.

It does not add up to 180 meaning you can not form a triangle with the three angle measures.

They are both right angles are therefore equal.

The answer is the AA postulate.

A

Note

ASA is a congruence postualate. If S is between two angles that can be shown to be corresponding and equal, then you will have 2 congruent triangles.

SSS if three sides of 1 triangle = 3 sides of a second triangle, then the 2 triangles are congruent. If the the three sides of one triangle are in a ratio with 3 sides of the other triangle, then the triangles could be similar, but that is not the case here.

SAS this is the terminology for congruence as well. We don't know enough to use it for similarity. Some sort of ratio would have to be mentioned to do that.

Medicare Tax

Social Security Tax

= 1.45% x 165000

Since 10230+2392.5 = 12622.50

Social security is taxed at 6.5 percent and medicare is taxed at 1.45 percent. it will always be that number unless the government changes it.

The categories are 6.2% as social security tax 1.45% as Medicare tax 0.9% as Medicare surtax for employees earning more than $200,000
