Answer 1
If all 3 angles of a Triangle MUST equal 180°, then we know that we use the equation (for this triangle) to find the angle measurements as (180-90)/2 which means we are dividing 90/2 which is 45° for each angle. But these angles are different measures, so we have to guess upon this and say that YOUR ANSWER IS D

What is the slope of the line?

A line's slope is defined as its inclination. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Consider Points 1 and 2 on a line. Point 1's coordinates are (x₁ , y₁), and Point 2's coordinates are (x₂, y₂).

Given that the continuously rising building is an elevator. It is 33 meters above the ground after 4 seconds, and 47 meters above the earth after 2 seconds.

Let the required equation model would be as:

y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x₂ -x]

x₁ = 4, y₁ = 33

x₂ = 2, y₂ = 47

⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x₂ -x]

Substitute values in the equation, we get

⇒ y - 33 = (47-33)/(2-4 )[x -4]

⇒ y - 33 = 14/(-2 )[x -4]

⇒ y - 33 = -7(x -4)

Therefore, the equation model is y - 33 = -7(x -4).

Answers

Answer:

  Jesse

Step-by-step explanation:

Jesse's distance in 60 seconds would be ...

  (60 s)(15 m)/(6 s) = 150 m

Peyton's distance in 60 seconds would be ...

  (60 s)(22 m)/(10 s) = 132 m

Jesse travels farther in the same amount of time, so Jesse is moving faster.

__

You might find it simpler just to compute the rate of each.

  Jesse: (15 m)/(6 s) = 2.5 m/s

  Peyton: (22 m)/(10 s) = 2.2 m/s

Jesse's speed is higher.

What is the equation in slope-intercept form of the line that passes through the points ( -4, 47) and ( 2 , -16)?

Answers

Answer:

[tex]-\frac{21}{2} x+5[/tex]

Step-by-step explanation:

To find the slope of the equation, you use [tex]\frac{rise}{run}[/tex] , or [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex] :

[tex]\frac{-16-47}{2+4}[/tex]=[tex]\frac{-63}{6}[/tex]=[tex]\frac{-21}{2}[/tex]

Then you have to find the y intercept. First, plug in the x of a point and solve:

[tex]\frac{-21}{2}[/tex] * 2= -21

Then, find the distance between the answer and the y of the given point. Since our answer is smaller than the y of the point, we'll get a positive y- intercept.

21-16=5

This will give us the equation:

[tex]-\frac{21}{2} x+5[/tex]

Quadrilateral PQRS is transformed by translating it 6 units to the right and then rotating it 90° clockwise
about the origin. Which coordinate pairs represent vertices of P'Q'R'S' after these two transformations?

Answers

Answer:

(y, -x -6)

Step-by-step explanation:

The coordinates of PQRS is not given, however we'll assume the coordinates of PQRS to be (x,y)

The first transformation: 6 units right

[tex](x,y) -> (x + b, y)[/tex]

Where b = 6

So, the new coordinates will be

[tex](x + 6, y)[/tex]

The second transformation: 90° clockwise

[tex](x,y) -> (y,-x)[/tex]

So, the new coordinates will be

[tex](x + 6, y)-> (y, -x -6)[/tex]

Hence, the new coordinates of PQRS is (y, -x - 6)

In a study of the impact of smoking on birth weight, researchers analyze birth weights (in grams) for babies born to 189 women who gave birth in 1989 at a hospital in Massachusetts. In the group, 74 of the women were categorized as smokers and 115 as non-smokers. The difference in the two sample mean birth weights (non-smokers minus smokers) is 281.7 grams and the 95% confidence interval is (76.5, 486.9). Which gives the best interpretation of what we can conclude about the impact of smoking on birth weight

Answers

Answer:

Given:

Total women -  189

Smokers - 74

Non-smokers - 115

The difference in 2 samples mean birth weight = 281.7 grams

95% confident that the mean weight = between 76.5 grams to 486.9  

solution:

The best interpretation would be -

95% confident that the babies of nonsmokers have a mean weight between 76.5 grams to 486.9 grams which is much more than the babies of women smokes by comparing smokers to nonsmokers from given data.

What is the point of an object where the force of gravity is considered to act?

Answers

Gravity always acts downward on every object on earth. Gravity multiplied by the object's mass produces a force called weight. Although the force of an object's weight acts downward on every particle of the object, it is usually considered to act as a single force through its balance point, or center of gravity.

Answer:

estimate 8.2x6.7 divided by 0.46

Answers

Answer:

Well, the correct answer is 119.4347826086956521739130 (after the 130 the whole decimal is repeated.

Step-by-step explanation:

Although if your assignment is asking for an estimate you could probably just say 119 since the first and second decimal is less then 5

The estimation of the expression 8.2 × 6.7 divided by 0.46 is approximately 112.

What is estimation?

It is a rough calculation of the value, number, quantity, etc. It doesn't use real calculation but estimation by some method like prediction, using approximation etc.

For this case, we've to esimate the value of the expression:

[tex]E = \dfrac{8.2 \times 6.7}{0.46}[/tex]

Instead of using exact values, let we use:

[tex]8.2 \approx 8\\6.7 \approx 7\\0.46 \approx 0.5 = 1/2[/tex]

Then, we get:

[tex]E = \dfrac{8.2 \times 6.7}{0.46} \approx \dfrac{8 \times 7}{1/2} = 2 \times 8 \times 7= 2 \times 56 = 112[/tex]

Thus, the estimation of the expression 8.2 × 6.7 divided by 0.46 is approximately 112.

Step-by-step explanation:

The "square" at the vertex of the angle indicates that it is 90 degrees. A triangle can be determined to be a right triangle if the side lengths are known. If the lengths satisfy the Pythagorean Theorem (a2+b2=c2) then it is a right triangle.
