We have been given that a graph that represents the amount of money in dollars that Tony expects to deposit in his account in terms of the number of years since opening the account.

We are asked to find the rate of change and initial value from our given graph.

We know that initial value is the point, where, graph intersects y-axis that is when x is equal to 0.

We can see that graph starts at 5000 on y-axis, therefore, initial value is $5000.

The rate of change will be equal to slope of line. Let us find slope of line using points (0,5000) and (1,7500).

[tex]m=\frac{7500-5000}{1-0}[/tex]

[tex]m=\frac{2500}{1}[/tex]

[tex]m=2500[/tex]

Therefore, the rate of change is $2500 per year.

The equation [tex]y=2500x+5000[/tex] represents the amount of money in dollars that Tony expects to deposit in his account.

The equation [tex]\rm y = 2500x+5000[/tex] represents the amount of money in dollars that Tony expects to deposit in his account.

The rate of change is $2500 per year.

Given that,

Tony opens a savings account.

The graph represents the amount of money in dollars.

Tony expects to deposit in his account in terms of the number of years since opening the account.

We have to determine,

The equation represents the amount of money in dollars that Tony expects to deposit in his account and rate of change per year.

According to the question,

The graph that represents the amount of money in dollars that Tony expects to deposit in his account in terms of the number of years since opening the account.

The rate of change and initial value from our given graph.

The initial value is the point, where, graph intersects y-axis that is when x is equal to 0.

The equation represents the amount of money in dollars that Tony expects to deposit in his account is,

[tex]\rm y = 2500x+5000[/tex]

The graph starts at 5000 on y-axis, therefore, initial value is $5000.

The rate of change will be equal to slope of line.

Let us find slope of line using points (0,5000) and (1,7500).

Therefore,

The slope of line is,

[tex]\rm m = \dfrac{y_2-y_1}{x_2-x_1}\\\\m = \dfrac{7500-2500}{1-0}\\\\m = 2500[/tex]

Hence, the rate of change is $2500 per year.

The probability of not drawing a silver ball, when the probability of drawing a silver ball is 1/3, is 2/3.

The probability of not drawing a silver ball can be found by subtracting the probability of drawing a silver ball from 1, since the sum of the probabilities of all possible outcomes must equal 1. If the probability of drawing a silver ball is 1/3, then the probability of not drawing a silver ball is 1 - 1/3 = 2/3.

Answer:

Step-by-step explanation:

Parallel lines have equal slopes

The product of the slopes of perpendicular lines = - 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

All the equations given are in slope- intercept form

y = 2x + 1 → with m = 2

y = [tex]\frac{1}{2}[/tex] x - 4 → with m = [tex]\frac{1}{2}[/tex]

y = x + 1 → with m = 1

y = - [tex]\frac{1}{x}[/tex] x - 3 → with m = - [tex]\frac{1}{2}[/tex]

y = 10 + x → y = x + 10 → with m = 1

Thus

y = x + 1 and y = 10 + x are Parallel since both have m = 1

y = 2x + 1 and y = - [tex]\frac{1}{2}[/tex] x - 3 are Perpendicular since 2 × - [tex]\frac{1}{2}[/tex] = - 1

Given:

Image of the figure.

To find:

The area of the figure.

Solution:

Length of larger rectangle = 9

Width of larger rectangle = 8

Area of larger rectangle = length × width

                                        = 9 × 8

Area of larger rectangle = 72 square units

Length of smaller rectangle = 4

Width of smaller rectangle = 2

Area of smaller rectangle = length × width

                                           = 4 × 2

Area of smaller rectangle= 8 square units

Area of the figure = Area of larger rectangle - Area of smaller rectangle

                              = 72 - 8

                              = 64 square units

The area of the figure is 64 square units.

Here we have , A prism is made up of 3 rectangles and 2 triangles. A rectangle has base of 12 and height of 10. A rectangle has base of 10 and height of 13. A rectangle has base of 10 and height of 5. 2 triangles have a base of 12 inches and height of 5 inches.  We need to find What is the surface area of the prism in square inches . Let's find out:

3 rectangles and 2 triangles

A rectangle has base of 12 and height of 10 :

⇒ [tex]Area = length(width)[/tex]

⇒ [tex]Area =12(10)[/tex]

⇒ [tex]Area =120[/tex]

A rectangle has base of 10 and height of 13

⇒ [tex]Area = length(width)[/tex]

⇒ [tex]Area =13(10)[/tex]

⇒ [tex]Area =130[/tex]

A rectangle has base of 10 and height of 5

⇒ [tex]Area = length(width)[/tex]

⇒ [tex]Area =5(10)[/tex]

⇒ [tex]Area =50[/tex]

2 triangles have a base of 12 inches and height of 5 inches.

⇒ [tex]Area = \frac{1}{2}base(height)(2)[/tex]

⇒ [tex]Area =12(5)[/tex]

⇒ [tex]Area =60[/tex]

Hence , Total Area :

⇒ [tex]120+130+50+60[/tex]

⇒ [tex]360in^2[/tex]

Correct option B) 360 square inches .

Answer:

C

Step-by-step explanation:

o find the side PQ ; we need to first find the length of the given line segment which is perpendicular to side PR; let name it as QS.

Now as ΔQSR is an right angled triangle.

and the length of the side QR and SR is given , so using Pythagorean theorem we have

QR^{2}=SR^{2}+QS^{2}

5^{2}=3^{2}+QS^{2}\\ \\QS^{2}=5^{2}-3^{2}\\\\QS^{2}=25-3=16=4^2

⇒  QS=4

Now again ΔQSP is an right angled triangle; so using Pythagorean theorem in ΔQSP we have

PQ^{2}=QS^{2}+PS^{2}\\ \\PQ^{2}=4^{2}+6^{2}=16+36=52

This means QS=\sqrt{52}=2\sqrt{13}

Hence, the length of side PQ is \sqrt{52}=2\sqrt{13}.

Hence, option C is correct.

The reflection across the x-axis changes the y-coordinate to its opposite. Thus, K(1, −1) becomes K(1, 1), N(4, 0) doesn't change, and Q(4, −4) becomes Q(4, 4).

The question's task is a reflection across the x-axis. This change involves flipping the coordinates in the plane over the x-axis. For a given point with coordinates (x, y), its reflection will have coordinates (x, -y). Let's apply this rule to the points given:

K(1, −1) will become K(1, 1)

N(4, 0) will remain N(4, 0) because it lies on the x-axis

Q(4, −4) will become Q(4, 4)

So, the reflected coordinates are K(1, 1), N(4, 0), Q(4, 4).

A square is defined as a quadrilateral with 4 congruent sides, but a rectangle is defined as a quadrilateral with 2 pairs of congruent sides, so unless the 2 pairs in a rectangle are the same length, no the rectangle is not a square. However all squares are rectangles.

"A rectangle is always a square" is false statement.

A rectangle is quadrilateral, in which opposite sides are equal in length and all four angles are equal to 90 degree.

A square is quadrilateral, in which all four sides are equal in length and all four angles are equal to 90 degree.

For 45-45-90 degree triangle

The length of other two legs: 5

For 30-60-90 degree triangle

The shorter leg= 3.53

The larger leg = 6.11

Step-by-step explanation:

length of Hypotenuse = [tex]\sqrt{50}[/tex]

We need to find possible lengths of the two legs of this triangle.

If the triangle is 45-45-90 degree triangle the length of other two sides would be same and can be found by:

[tex]Length\,\,of\,\,leg:\frac{\sqrt{50} }{\sqrt{2} } \\Length\,\,of\,\,leg:5[/tex]

Since both legs are of same size so, length of other leg = 5

If the triangle is 30-60-90 degree triangle then:

To find shorter length: Divide hypotenuse by 2.

To find other side length: Multiply shorter length by [tex]\sqrt{3}[/tex]

The shorter leg = [tex]\frac{\sqrt{50} }{2}= 3.53[/tex]

The other leg (larger) = [tex]3.53\times \sqrt{3} =6.11[/tex]

Answer: Feet

Step-by-step explanation:

Well, Katie can use whatever unit of measure she prefers. However, in this case she must take into account the measuring instrument that she is going to use and the unit of measurement that is generally used or according to the established rules.

On the other hand, a softball field has an average area of ​​[tex]225 ft^{2}[/tex], which is quite a lot. Therefore Katie needs to use a convenient unit of measure (let's assume she uses a measuring tape, which gives her the option to measure in feet or inches) to quickly measure the distance between the pitcher mound and home plate.

So, if we have to choose between feet and inches, we must consider the following:

[tex]1 ft=12 in[/tex]

This means [tex]ft[/tex] as a unit of distance is greater than [tex]in[/tex]. Hence, Katie should use feet instead of inches.

In addition, according to the Softball rules, generally the dimensions are given in feet. So, it is better for Katie to use feet to measure the distance from Pitchers Mound to Home Plate.

Final answer:

While Elena's method of dividing the points equally on either side of a line might be a rough starting point for finding a 'line of best fit,' accurate data analysis requires more sophisticated methods, like least squares regression, to determine how well a line truly fits a set of data points.

Explanation:

Elena's consideration that a line is a good fit because half of the points are on one side and half are on the other may indicate an attempt at balancing data around a potential 'line of best fit' when visually estimating in scatter plots. However, a good fit in the context of data analysis typically relates to how closely the line follows the trend of the points, which is better determined by methods such as least squares regression, rather than just the number of points on either side of the line.

Statistical measurements, such as the correlation coefficient, are used to quantify how well a line fits the data in question. Therefore, while Elena's observation might be useful as an initial, rough estimation, more rigorous statistical methods would provide a more accurate assessment of a good fit for the data.
