The point of intersection of f(x) and [tex]f^{-1}[/tex](x)   is (3, 3)

"It defines a relation between input and output values."

"In function, for each input there is exactly one output."

"The inverse function of x = f(m) is m =[tex]f^{-1}[/tex] , where x, m are real values"

For given question,

A function  f(x) and its inverse function [tex]f^{-1}(x)[/tex],  are both plotted on the same coordinate plane.

We know that the inverse function [tex]f^{-1}(x)[/tex]   is the mirror image of the function f(x.)

This means, both the functions must be symmetric about the line y = x.

The curve of inverse function [tex]f^{-1} (x)[/tex]  would cross the Y-axis at (0, 2), changes direction at (-1, -1) and crosses the X-axis at (-2, 0)

And both the functions intersect each other only on y = x

The point which satisfy the line y = x is (3, 3)

Therefore, the point of intersection of f(x) and[tex]f^{-1} (x)[/tex] is (3, 3)

The complete question is : If f(x) and its inverse function, f–1(x), are both plotted on the same coordinate plane, what is their point of intersection?

f. Third quarter closing balance = $6,524.40548145

g. Interest for the fourth quarter = $8.15550685975

h. The amount of interest earned in a year is about $32.56

What is an interest earned on an amount?

An interest is the amount a borrower pays to a lenders as to make use of the lender's funds.

The amount Fred deposited, P = $6,500

The interest paid by the account, r = 0.5% compounded quarterly

a. The first quarter interest can be found by the formula;

C.I. = P[tex](1+ r/4)^{4 . 1/4}[/tex] - P

Therefore

C.I. = 6500 x (1 + [tex]\frac{0.5/100}{4}[/tex]) - 6500 = 8.125

b. The first quarter ending balance is therefore;

A = P + C.I.

A = $6,500 + $8.125 = $6,508.125

c. The second quarter's interest can be found from the formula;

C.I. = 6508.125 x (1 + [tex]\frac{0.5/100}{4}[/tex]) - 6508.125 = 8.13515625

The second quarter's interest is $8.13515625

d. The second quarter ending balance is therefore;

A = $6,508.125 + $8.13515625 = $6,516.26015625

The second quarter ending balance is $6,516.26015625

e. The third quarters interest is therefore;

C.I. = 6516.26015625 x  (1 + [tex]\frac{0.5/100}{4}[/tex]) - 6516.26015625 = 8.1432520325

The third quarter's interest is about $8.1433

f. The third quarter's ending balance is therefore;

A ≈ $6516.26015625 + $8.1432520325 = $6,524.40548145

The third quarter's ending balance is $6,524.40548145

g. The fourth quarter's interest can be found as follows;

C.I. = 6524.40548145 x (1 + [tex]\frac{0.5/100}{4}[/tex]) - 6524.40548145 = 8.15550685975

The fourth quarter's interest is; $8.15550685975

h. The balance at the end of one year is therefore;

Balance = C.I. fourth quarter + Principal for the fourth quarter

Therefore;

Balance = $6,524.40548145 + $8.15550685975 = $6,532.56098831

i. The interest the account earns in a year is therefore;

$6,532.56098831 - $6,500 = $32.5609883

Step-by-step explanation:

Mrs. Smith will need to reserve buses for 7 classes of Fourth graders, with 20 students in each class, for a total of

7 * 20 = <<7*20=140>>140 students.

Since 30 students fit on a bus, Mrs. Smith will need to reserve

140 / 30 = <<140/30=4.67>>4.67 buses.

Since Mrs. Smith can't reserve a partial bus, she will need to reserve 5 buses for the trip.

Answer: 5 busses, you have to multiple the number of students by the amount of classes (7 x 20) to get a product of 140 students. If only 30 can fit on to each bus you have to divide 140 by 30 and you get 4.6666667 so you need to round up to get an answer of 5 busses

If a blood stain has a length of 3.0cm and a width of 1.5cm, the angle of impact is 30 degrees

The length of the blood stain = 3 cm

The width of the blood stain = 1.5 cm

The equation for measuring the angle of impact is

sin (angle of impact) = The width of the blood stain / The length of the blood stain

Angle of impact = sin^-1 (The width of the blood stain / The length of the blood stain)

Substitute the values in the equation

Angle of impact = sin^-1(1.5 / 3)

= sin^-1(0.5)

The correlation of the scatterplots are defined as;

The math and English scores show; A positive correlation.

The math and chemistry scores show; A negative correlation

In correlation in statistics, it could either be positive correlation, negative correlation or no correlation at all.

A positive correlation is defined as a relationship between two variables that tend to move in the same direction. Thus, a positive correlation exists in the event that one variable tends to decrease while the other variable decreases, or one variable tends to increase while the other variable increases.

A negative correlation is defined as a relationship between two variables whereby one variable increases while the other decreases, and vice versa.

No correlation means there is no relationship between the two variables.

Now, for scatterplot of the math and English scores shown, we see that majority of the english scores increase as the maths scores increase and as sch it is a positive correlation.

Answer:

11) KF = DB

12) DC=YZ

13) <C = <W

14) <S and <K

Step-by-step explanation:

11) For this question, we want to try and use SSS to prove the triangles are congruent. SSS stands for side-side-side postulate, so all sides have to be equivalent. We already have ED = FB as given, and DF = DF due to reflexive property. From this information, we already have two sides. Additional information that would be needed to figure out the third side is KF = DB, as it's the only side we are missing.

12) For this question, we want to use SAS postulate, which stands for side-angle-side. We already have one side congruent, which is BC=YX. We have one angle congruent which is <C = <Y. With this information, we have one side and one angle. This means that we need to find another side that is congruent. The side that we need to find here is DC=YZ, as it will help us prove the triangles are congruent with SAS.

13) For this question, we want to use AAS, which stands for angle-angle-side. We already have one angle congruent, which is <CDE = WDE. We have one side congruent as well, which is DE = DE due to reflexive property. With this given information, we have one angle and one side. We only need one more angle before the other angle to figure this out. The angles that are needed are <C = <W.

14) For this question, we want to use ASA, which stands for angle-side-angle. The one angle we have already is <KTM = <UTS, which is because of vertical angles are congruent. The one side that we have is ST=TK. With this, we have one angle and one side. We just need one more angle to prove this, which would be <S and <K.

Remember, for triangle congruency postulates, they have to be in order. They cannot just be out of order. For example, in question 14, we have to find the measures in order. First we need an angle, side, and then another angle. The first angle is <S and <K, then the side we have is ST=TK, and then our last angle, <KTM = <UTS.

Equations with the highest degree of 1 are called linear equations. This means that the exponent of the variable in the linear equation is greater than 1. The graph of a linear equation is always a straight line.

A linear equation is an algebraic equation in which each term has exponent 1, and the graph of this equation is always a straight line. For this reason, it is called a "linear equation".

Given system of equation:

7x - 7y = 28 ..........(1)

2x - 7y = 1 .............(2)

Solve this system of linear equation. Find the value of 7y from equation (1) and substitute in equation(2)

7x - 7y = 28

7x - 28 =7y .............(3)

Substitute this value in equation (2)

2x - (7x - 28) = 1

2x - 7x + 28 = 1

-5x + 28 = 1

The probability their average salary is less than $33,200 is = 0.6554

Given that,

Mean = $32,000

Standard deviation = $3,000

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Standard deviation (SD) is a widely used measurement of variability used in statistics. It shows how much variation there is from the average (mean). A low SD indicates that the data points tend to be close to the mean, whereas a high SD indicates that the data are spread out over a large range of values.

The Z score is used to calculate how many standard deviations above or below the mean the raw score is. It comes from,

z = (x- μ) / σ           (Equation-1)

Where,

x=raw score,

μ=mean,

σ=standard deviation

μ=32,000,

σ=3,000

Average salary is less than $33,200

x < 33,200

We can substitute values in Equation-1,

z = (33,200-32,000)/3000

z = 1200/3000

z = 0.4

Using the normal distribution table as a guide,

P(x < 33,200) = P(z < 0.4)

P(x < 33,200) = 1-P(z>0.4)

P(x < 33,200) = 0.6554

Therefore,

Answer:

Let $x$ be the measure of the included angle. We can use the formula for the area of a triangle to find an equation in terms of $x$.

The area of a triangle is given by $\frac{1}{2}bh$, where $b$ is the length of the base and $h$ is the length of the altitude from the base to the opposite vertex. In this case, the base is 87 and the altitude is the length of the line segment from the vertex opposite the included angle to the base, which we can find using the Law of Sines:

$$\frac{h}{\sin x} = \frac{19}{\sin(180^\circ-x)}$$

$$h = \frac{19\sin x}{\sin(180^\circ-x)}$$

Substituting this expression for $h$ into the formula for the area of the triangle, we get

$$\frac{1}{2}bh = \frac{1}{2} \cdot 87 \cdot \frac{19\sin x}{\sin(180^\circ-x)} = 474$$

Solving this equation for $x$ is somewhat difficult, but we can use a calculator or computer to approximate the value of $x$. Using a calculator, we find that $x \approx 31.4^\circ$. Rounding to the nearest tenth of a degree, the measure of the included angle is $\boxed{31.4^\circ}$.
