The expression is:

f(-2) = 23, f(3) = 5, f(4) = 5, f(6) = 5, f(9) = -3

The function is

f(x) = 5x² + 3  x< 3

     = 5           3≤x ≤ 6

     = 6-x        x>6

a) f(-2) for x<3

So we have 5x² + 3

5(-2)² + 3

= 5 × 4 + 3

= 20 + 3

= 23

b) f(3)

as the range is 3≤ x ≤6

for which we have a value 5

So f(3) = 5

c) f(4)

As the range is 3≤ x ≤ 6 for which the value is 5.

So f(3) = 5

d) f(6)

As the range is 3≤ x ≤ 6

So the value is 5

f(6) = 5

e) f(9)

The range is x>6 for this we have 6-x

So 6-x

= 6 - 9

= -3

Therefore the value of the function is f(-2) = 23, f(3) = 5, f(4) = 5, f(6) = 5 and f(9) = -3.

create a non linear function that has a solution at (-2,6). Include a calculation that shows why this is a solution to your function.

Answers

In order to find a nonlinear function that has a solution at (-2,6) we need to choose first a parent function that is no linear in this case, we will use

[tex]y=x^2[/tex]

in order to know that the solution is (-2, 6) so if I introduce the value of x coordinate which is -2 in the function we need to have as result 6

In this case, taken the parent function above and in order to have the desired result we have the next calculations

Investor A decided to purchase a home with a loan amount of $390,000, 3.30% annually fixed rate for a 30 years term, and one payment per month. What is the monthly payment for this mortgage? Round to the nearest cent

Answers

The monthly payment for this mortgage is $2156

What is simple interest?

It is the interest calculated on the principal at a given rate for a time period.

We have,

Principal = $390,000

Rate = 3.30%

Time = 30 years

The simple interest is given by:

SI:

= P x R x T / 100

= (390,000 x 3.30 x 30) / 100

= (390,000 x 330 x 30) / (100 x 100)

= 39 x 330 x 30

= 386100

Total amount to pay in 30 years.

= Principal + SI

= 390,000 + 386,100

= 776100

The monthly payment:

30 years = 12 x 30 months = 360 months

Now,

Monthly payment:

= 776100 / 360
= 2155.83

= $2156

Thus,

The monthly payment for this mortgage is $2156

Which of the following boxplots correctly displays the distribution of quiz grades?

Answers

If a stemplot as shown in the attachments attached alongside the question statement, display the grades (out of 30) that 26 students received on a quiz, and has values [12, 14, 15, 16, 20, 22, 23, 23, 24, 24, 24, 25, 25, 25, 26, 26, 26, 26, 27, 27, 27, 28, 28, 29, 29, 30], then the boxplot (A) correctly displays the distribution of quiz grades.

As per the question statement, a stemplot as shown in the attachments attached alongside the question statement, display the grades (out of 30) that 26 students received on a quiz, and has values [12, 14, 15, 16, 20, 22, 23, 23, 24, 24, 24, 25, 25, 25, 26, 26, 26, 26, 27, 27, 27, 28, 28, 29, 29, 30].

We are required to determine which one of the four boxplots provided in the attachments correctly displays the distribution of quiz grades.

To solve this question, first let us observe the distribution of the grades, where the grade 13, 17, 18, 19, 20 and 21 are missing. Hence, the set is a discontinuous one.

Looking at options (B) and (D), these boxplots have a straight continuous line from 12 upto 30, which means that the grades 13, 17, 18, 19, 20 and 21 are also included in the set. This is false, and hence, options (B) and (D) cannot be the correct answers.

Coming to Option (C), it has a continuous line from 15 to 30, which means, the grades [17, 18, 19, 20 and 21] are also included in the set, and this is also not true. Hence, option (C) is also not our correct answer.

Finally coming to option (A), It has four individual dots over 12, 14, 15 and 16, and then, a gap, and a continuous line from 20 to 30 after the gap. From our set, we can observe that, 12, 14, 15 and 16 are in-fact present in the set, each of them having occurrence once only, and thus the four individual dots over 12, 14, 15 and 16 correctly addresses this situation. Also, every number between 22 and 30 are present in the set, and the numbers of (23, 24, 25, 26 and 27) have the most occurrences, which the boxes on top of (23 - 27) again correctly address.

Hence, our correct answer is option (A).

Stemplot: In Statistics, a stem and leaf plot, or a stem plot, is a technique used to classify discrete or continuous variables, and used to organize data as they are collected. Since it looks something like a bar graph, and each number in the data is broken down into a stem and a leaf, it gets the name of Stemplot.Boxplot: In Statistics, a boxplot is a graphical rendition of statistical data based on the minimum, first quartile, median, third quartile, and maximum of a set of observations, and the name "box plot" comes from the fact that the graph looks like a rectangle with lines extending from the top and bottom.

Find the product. Write the product in rectangular form, using exact values.

Answers

Explanation

We must find the product of complex numbers and write it in rectangular form i.e. like a+ib where a and b are real numbers. In order to do tthis we first need to write the values of the sine and cosine of 120° and 210°. For this purpose we can use a table displaying the values of the trigonometric functions for several angles. However, these tables usually display the values for angles between 0° and 90° like the following one:

However this table is still useful. 120° is an angle in the second quadrant which means that it has the same sine as an angle of the first quadrant that meets x=180°-120° and its cosine is the same but multiplied by -1. We have x=180°-120°=60° which means that:

[tex]\begin{gathered} \sin120^{\circ}=\sin60^{\circ}=\frac{\sqrt{3}}{2} \\ \cos120^{\circ}=-\cos60^{\circ}=-\frac{1}{2} \end{gathered}[/tex]

We can do something similar for 210°. It's in the third quadrant which means that both its sine and cosine are thoes of x=210°-180°=30° but multiplied by -1. Then we get:

[tex]\begin{gathered} \sin210^{\circ}=-\sin30^{\circ}=-\frac{1}{2} \\ \cos210^{\circ}=-\cos30^{\circ}=-\frac{\sqrt{3}}{2} \end{gathered}[/tex]

Now that we found the sine and cosine of both angles we can rewrite the product:

[tex]\begin{gathered} \lbrack4(\cos210^{\circ}+i\sin210^{\circ})\rbrack\cdot\lbrack5(\cos(120^{\operatorname{\circ}})+\imaginaryI\sin(120^{\operatorname{\circ}}))\rbrack= \\ =\lbrack4(-\frac{\sqrt{3}}{2}-i\frac{1}{2})\rbrack\cdot\lbrack5(-\frac{1}{2}+\mathrm{i}\frac{\sqrt{3}}{2})\rbrack=\lbrack-2\sqrt{3}-2i\rbrack\cdot\lbrack-\frac{5}{2}+\mathrm{i}\frac{5\sqrt{3}}{2}\rbrack \end{gathered}[/tex]

Then we get:

[tex]\begin{gathered} \lbrack-2\sqrt{3}-2i\rbrack\cdot\lbrack-\frac{5}{2}+\mathrm{i}\frac{5\sqrt{3}}{2}\rbrack=2\sqrt{3}\cdot\frac{5}{2}-i2\sqrt{3}\cdot\frac{5\sqrt{3}}{2}+i2\cdot\frac{5}{2}-i\cdot i\cdot2\cdot\frac{5\sqrt{3}}{2} \\ =5\sqrt{3}-i15+i5+5\sqrt{3}=10\sqrt{3}-10i \end{gathered}[/tex]Answer

0.0000235 in scientific notation

Answers

Answer:

2.35 × 10⁻⁵

Step-by-step explanation:

Scientific notation (also called "Standard form") is written in the form

a × 10ⁿ where 1 ≤ a < 10 and n is any positive or negative whole number.

To convert a number into scientific notation, move the decimal point to the left or right until there is one digit to the left of the decimal point.

The number of times you have moved the decimal point is the power of 10 (the value of n).

If the decimal point has moved to the left, n is positive.If the decimal point has moved to the right, n is negative.

To convert 0.0000235 to scientific notation:

Move the decimal point 5 places to the right so that a = 2.35.  As the decimal point has been moved 5 places the right, n = -5.

Therefore,  0.0000235 = 2.35 × 10⁻⁵.

What is the ratio of the areas of ΔABC to ΔA'B'C' ?

Answers

The first step is to find the scale factor relating ABC to A'B'C'. Since they are dilated, ABC is similar to A'B'C'. This means that the ratios of their corresponding sides are equal. Thus,

AB/A'B' = BC/B'C' = AC/A'C'

From the information given,

AB = 7

A'B' = 28

Thus,

ratio of ABC to A'B'C' = 7/28 = 1/4

Ratio of area of ABC to A'B'C' = (1/4)^2

Ratio of area of ABC to A'B'C' = 1/16

Answers

Hello there. To solve this question, we have to remember some properties about roots of polynomials.

Given the following function:

[tex]f(x)=(2x+6)\cdot(x-4)[/tex]

We want to determine its roots.

For this, we want to determine the values of x such that

[tex]f(x)=0[/tex]

Then we have that

[tex](2x+6)\cdot(x-4)=0[/tex]

We know that a product of two values is equal to zero if and only if one of them is equal to zero.

So we have that

[tex]2x+6=0\text{ or }x-4=0[/tex]

Subtract 6 on both sides of the first equation, we get

[tex]2x=-6[/tex]

Divide both sides of the equation by a factor of 2

[tex]x=-3[/tex]

Now for the second equation, add 4 on both sides of the equation

[tex]x=4[/tex]

Hence we say that the roots of this function are

Given

From the question, we can see that the bottom of the ferris wheel is 30 feet about the ground and also while rotating, it can move to a height of 550 feet off the ground. In essence the actual height the ferris wheel can attain is

[tex]h=550-30=520[/tex]

The amplitude then becomes half of the height which is

[tex]A=\frac{h}{2}=\frac{520}{2}=260[/tex]

The vertical shift the Ferris wheel undergoes becomes the sum of the amplitude and its distance above the ground.

[tex]D=260+30=290[/tex]

Since it takes the Ferris wheel 15 minutes to move from bottom to top, it will take it twice that to complete one revolution which will be its period.

[tex]T=2\times15mins=30[/tex]

Therefore, the frequency B, becomes;

[tex]B=\frac{2\pi}{T}=\frac{2\pi}{30}=\frac{\pi}{15}[/tex]

We can then place in the above parameters to form the equation.

[tex]y=Acos(B(t+C))+D\Rightarrow260cos(\frac{\pi}{15}(t+C)+290[/tex]

The last missing parameter is the phase shift C. At time t =0, the function (y) has a position at 30. Therefore,

[tex]\begin{gathered} 30=260cos(\frac{\pi}{15}C)+290 \\ 260cos(\frac{\pi}{15}C)=-290+30 \\ 260cos(\frac{\pi}{15}C)=-260 \\ divide\text{ both sides by 260} \\ \frac{\begin{equation*}260cos(\frac{\pi}{15}C)\end{equation*}}{260}=\frac{-260}{260} \\ cos(\frac{\pi}{15}C)=-1 \\ \frac{\pi}{15}C=cos^{-1}(-1) \\ \frac{\pi}{15}C=\pi \\ C=\frac{15\pi}{\pi} \\ C=15 \end{gathered}[/tex]

These are equations with constant average rates of change

How to determine the solution that makes the equation true?

The equation is given as

4(x-2)=2x-3

Rewrite the equation properly

So, we have

4(x - 2)=2x - 3

The above equation is a linear function with one variable

So, we have

Open the brackets in the above equation

So, we have

4x - 8 =2x - 3

Add 8 to both sides of the equation

So, we have

4x =2x + 5

Subtract 2x from both sides of the equation

So, we have

3x = 5

Divide both sides of the equation by 3

So, we have

x = 5/3

Hence, the value of x in the equation is 5/3

What is the degree of the polynomial, 105y75+125x5-100x10?

Answers

The degree of the polynomial is the largest of these three values, which is 75

What is polynomial ?

Algebraic expressions called polynomials include constants and indeterminates. Polynomials can be thought of as a type of mathematics. Nearly all branches of mathematics employ them to express numbers, and calculus is one of those branches where they play a crucial role.

Simply locate the highest exponent in the formula to determine the degree of the polynomial. The degree of the polynomial is seven because it is the highest exponent above.

There are multiple variables in the polynomial. The biggest sum of ALL of the exponents for ALL of the variables in a term is the polynomial's degree.

Given that := 105[tex]y^{75} + 125^{5} - 100x^{10}[/tex]

= 105[tex]y^{75} + 125^{5} - 100x^{10}[/tex]

To find the degree of a polynomial, simply find the highest exponent in the expression.  As seven is the highest exponent above, it is also the degree of the polynomial.

what is the median? -95, -94, -93, 95, 91, -92, -89, -92, -98

Answers

Given the set of the data:

[tex]-95,-94,-93,95,91,-92,-89,-92,-98​[/tex]

Arranging the data in order from the least to the greatest:

[tex]-98,-95,-94,-93,-92,-92,-89,91,95[/tex]

The number of the data = 9

so, the median is the number which is in the middle

It will be number (9+1)/2 = 10/2 = 5

so, the median = -92

Which of the following quadratic functions has a graph that opens downward? Check all that apply. A v=Bx2- 8x– 13 B. v= - (3+x? e. v=zx2 - 13x+5 O d. v=2r-

Answers

Ok, so

Remember that:

For any quadratic equation of the form:

[tex]y=ax^2+bx+c[/tex]

- If the leading coefficient is greater than zero, the parabola opens upward, and

- If the leading coefficient is less than zero, the parabola opens downward.

So, here we have the following functions:

[tex]v=\frac{1}{3}x^2-8x-13[/tex]

The leading coefficient is greater than zero, so this parabola opens upward.

Option B:

[tex]\begin{gathered} v=-(3+x^2) \\ v=-x^2-3 \end{gathered}[/tex]

The leading coefficient is less than zero, so this parabola opens downward.

Option C:

[tex]v=\frac{2}{3}x^2-13x+5[/tex]

The leading coefficient is greater than zero, so this parabola opens upward.

Option D:

[tex]v=2x-x^2[/tex]

The leading coefficient is less than zero, so this parabola opens downward.

Therefore, the correct options are B and D.

The constant of proportionality is equal to 11.

Constant of Proportionality

The constant of proportionality is the ratio that relates two given values in what is known as a proportional relationship. Other names for the constant of proportionality include the constant ratio, constant rate, unit rate, constant of variation, or even the rate of change.

In this question, the constant of proportionality is that value that doesn't change or represents the number of players while x represented the number of games they played.

The constant of proportionality can be solved mathematically as

[tex]y = 11x\\x = 2\\22 = 11(2)\\22 = 22\\[/tex]

The constant of proportionality is the value that makes y = 11x and it is 11.
