Answer:

Step-by-step explanation:

Left Frame

f(x) is a horizontal line from x = 1 to x = 3. So the y values are the same in that interval.

when y = 1, x = 3

so f(3) = 1

The answer is III

Question Second from the right

The trick is to get the denominator so it is not a complex number. You do that by multiplying by the conjugate which is 8 - 2i. If you do that to the denominator, you must do it to the numerator.

Denominator: (8 + 2i)(8 - 2i) = 64 - 16i + 16i - 4i^2

Denominator: 64 + 4

Denominator: 68

Numerator: (3 - 5i)(8 - 2i)

Numerator: 24 - 6i - 40i + 10*i^2

Numerator: 24 - 46i - 10

Numerator: 14 - 46i

So in some form or other the answer is

[tex]\dfrac{14 - 46i}{68} = \dfrac{7}{34} - \dfrac{23i}{34}[/tex]

Right Frame

Here, the slopes must be the same. So calculate the slope of the left line and make that equal to the slope of the right line's expression

Left Line

Left = (y2 - y1)/( x2 - x1) = (2 - 0)/(0 - - 5) = 2/5

Right line

Right  = (y2 - y1) / (x2 - x1) = (0 - - 4) / (p - 0) = 4/p

Now Equate them (they are parallel and have the same slope)

2/5 = 4/p           Cross multiply

2p = 5*4            Combine the right

2p = 20              Divide by 2

2p/2 = 20/2       Do the division

p = 10

Answer:

Step-by-step explanation:

Rewrite this equation in standard form:

x² - 2x + 1 - 1 + y² + 6y + 9 = 0, or

  (x - 1)² + (y + 3)² = 1

Compare this to:

   (x + h)² + (y + 3)² = r²

We see here that (h, k), the center of the circle, is (1, -3), and the radius of the circle is 1.

Answer:

the center is at (1, -3)

Step-by-step explanation:

The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r".

So we need to write the ecuation x^2 + y^2 - 2x + 6y + 9 = 0 in the format above.

So we have:

x^2 + y^2 - 2x + 6y + 9 = (x^2 -2x + 1) + (y^2 + 6y + 9) - 1

(x^2 -2x + 1) + (y^2 + 6y + 9) - 1 = (x-1)^2 + (y+3)^2 - 1

So now, looking at the equation:  (x-1)^2 + (y+3)^2 = 1

We know that h=1 and k=-3. So the center is at (1, -3)

Question 1.

They usually charge $7 per day to swim at the pool. The offer consist of: Paying an enrollment fee is $30 and then $4 per day.

It means that by enrolling you save 3$ per day. If you save $3 per day, in 10 days you would be saving $30 dollars which is the enrollment fee. This can be calculated by applying the rule of three:

If I save $3 -------------> 1 day?

             $30 ----------> How many days?

Days = ($30 * 1day)/$3 = 10 days.

Then, after 10 days, the offer becomes a better deal.

Question 2.

I only have $60 to spend the rest of the summer. Which offer would be the best value?

NOT paying the enrollment fee would be the best value. The reason is the following:

If I pay the enrollment fee, I spend $30. So I just have $30 remaining. Then, paying $4 a day, it means that I could just pay 7 daily passes, it means that I could go to the pool just seven days.

If I don't pay the enrollment fee, I would have the entire $60 dollars to buy daily passes. The price of each pass would be $7, so $60/7 = 8.5. It means that I could go just 8 days to the pool. One day more than the other option.

So if I only have $60, the best option is NOT to pay the enrollment fee.

Question 3.

If the swim center decides to change the the enrollment fee to $23 and then paying just $4 per daily pass. Then:

If I have only $60 dollars, after paying the enrollment fee I will only have $37.

If each daily pass costs $4, then I will be able to buy $37/$4 = 9.25 = 9 daily passes.

So, if the swim center decides to change the enrollment fee to $23, the the best option is paying the enrollment fee.

ANSWER

B' has coordinates (16,14).

EXPLANATION

The given coordinates of square ABCD are :

A (2,7) , C (8,1),D (2,1)

In order to form a square, the coordinates of B should be: (8,7)

The mapping for dilation with a scale factor 2, about the origin is

[tex](x,y)\to (2x,2y)[/tex]

This implies that:

[tex]B(8,7)\to B'(2 \times 8,2 \times 7)[/tex]

When we simplify we get:

[tex]B(8,7)\to B'(16,14)[/tex]

Hence B' has coordinates (16,14).

Answer:

  $362.57

Step-by-step explanation:

A suitable calculator or finance app can find the monthly payment for you. This result comes from a TI-84 calculator.

___

The second attachment shows the parameters of the payment function. With 20% down, Anthony is only financing 80% of the price of his car. Of course, there are 12 months in a year, so 4 years worth of payments will be 48 payments. The calculator uses negative values for amounts you pay.

___

No doubt your reference material shows you a formula for computing loan payments. One such is ...

  A = Pr/(1 -(1+r)^-n)

where r is the monthly interest rate, 0.068/12, and n is the number of payments, 48. The principal amount of the loan, P, will be 19,000×0.80. This formula gives the same result as that shown above and below.

Answer:

Total price paid is 20,033.60

Step-by-step explanation:

20% of 19,000 is 3,800

19,000 - 3,800 = 15,200

6.8% of 15,200 is 1,033.60

3,800 + 15,200 + 1,033.60 = 20,033.60

Answer:

y = -5x + 1

Step-by-step explanation:

y = -5x + 1 is correct.  

Note that at x = 0, y = 0 + 1 = 1 → (0, 1), and

                at x = 1, y = -5 + 1 = -4 → (1, -4), and

                 at x = -1, y = 5 + 1 = 6  → (-1, 6)

The linear function that maps the diagram is:

[tex]y = -5x + 1[/tex]

A linear function has the following format:

[tex]y = mx + b[/tex]

In which:

In the diagram, when [tex]x = 0, y = 1[/tex], thus, the y-intercept is [tex]n = 1[/tex], and:

[tex]y = mx + 1[/tex]

Point (1,-4) is on the diagram, which means that when [tex]x = 1, y = -4[/tex], and this is used to find m.

[tex]y = mx + 1[/tex]

[tex]-4 = m + 1[/tex]

[tex]m = -5[/tex]

Then, the equation is:

[tex]y = -5x + 1[/tex]

In one hour Nina runs 51 ¹/₅ miles.

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

In 1/4 hours, Number of laps run by Nina = 12 ⁴/₅.

To find the number of laps Nina could run in one hour,

Use ratio property,

Since,

In 1/4 hours = 12 ⁴/₅ laps = 64 / 5 laps

In 1 hour = (64 / 5) x 4

               = 256 / 5

                = 51 ¹/₅

Nina runs 51 ¹/₅ laps in one hour.

For this case we have that by definition, the slope point equation of a line is given by:

[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cutoff point with the y axis

By definition, if two lines are perpendicular, the product of their slopes is -1. That is to say:

Answer:

b. sin or csc

Step-by-step explanation:

Remember that sine trigonometric function is the ratio of the opposite side of a right triangle to its hypotenuse; in other words:

[tex]sin(\alpha )=\frac{opposite-side}{hypotenuse}[/tex]

Also, the cosecant is the inverse of sine, so:

[tex]csc(\alpha )=\frac{1}{sin(\alpha) } =\frac{hypotenuse}{opposite-side}[/tex]

Now, for our triangle, our angle is 27°, the longest side of it is TS, and the opposite side of our angle (27°) is TR; therefore, [tex]\alpha =27[/tex], [tex]hypotenuse=TS[/tex], and [tex]opposite-side=TR[/tex].

Replacing values:

- Using the sine trigonometric function

[tex]sin(\alpha )=\frac{opposite-side}{hypotenuse}[/tex]

[tex]sin(27)=\frac{TR}{TS}[/tex]

[tex]sin(27)=\frac{TR}{TS}[/tex]

[tex]sin(27)=\frac{7}{TS}[/tex]

[tex]TS=\frac{7}{sin(27)}[/tex]

[tex]TS=15.42[/tex]

- Using the cosecant trigonometric function

[tex]csc(\alpha )=\frac{hypotenuse}{opposite-side}[/tex]

[tex]csc(27)=\frac{TS}{TR}[/tex]

[tex]csc(27)=\frac{TS}{7}[/tex]

[tex]TS=7csc(27)[/tex]

[tex]TS=15.42[/tex]

We can conclude that we can use either the sine trigonometric function or the cosecant trigonometric function to solve the problem.

Answer:

8%

Step-by-step explanation:

I = PRT (Interest = Principal x Rate x Time)

Note that:

Interest = $320

Principal = $2000

Time = 2 years

Plug in the corresponding number to the corresponding variables.

320 = (2000)(r)(2)

Simplify. Combine like terms.

320 = (4000)r

Isolate the variable, r. Divide 4000 from both sides.

(320)/4000 = (4000r)/4000

r = 320/4000

r = 0.08

Change the decimal into a percentage.

r = 0.08 = 8/100 = 8%

8% is your interest rate.

Answer:

No, just because the amount of recylcing has gone up this year does not mean that we can conclude it's more this year than ever before. We are only given information for this year and last year, we can't come to that conclusion unless we are given information about the amount of recyling done in all the years.

I reject this conclusion because it says that the people have recycled more this year than ever before.

Generally ever before mean since a long time ago and from the data given we only have recording of last year, not any year before that. If the conclusion had said that the people in mesopotamiaville are recycling more this year than last year. It would have been correct but instead it has given us an invalid conclusion because from the data we have been given we can not possibly gather any other information that can help us accept or reject the conclusion. So therefore the conclusion given is invalid. Hence the reason I reject this conclusion.

Answer:

y= sqrt(x+4)

Step-by-step explanation:

The reason is because the function is translated horizontally to the left.

The base function is y=sqrt(x)

The option A. f(x) sqrt (x-5) + 1, the graph should be translated horizontally 5 units to the right. It's not the case. And translated 1 unit vertically.

Option B. f(x) = sqrt (x-2) the graph should be translated horizontally 2 units to the right. It's not the case.

Option C. f(x) = sqrt(x), the graph should start at x=0. It's not the case.

The option D.  f(x) = sqrt(x+4), the function is translated 4 times horizontally to the left. So this is the case.

B. Right by 4 units

Step-by-step explanation:

Let's start by expressing g(x) formula in a simpler form.  x² - 8x + 16 is quite easy to factor into (x - 4)²

so, we have g(x) = (x - 4)² and f(x) = x²

For which value of x will g(x) and f(x) = 0?

g(x) will equal 0 if x = 4

f(x) will equal 0 if x = 0

So, the difference is 4 units.  

Since f(x) would have to move from 0 to 4 to join g(x), the movement will be to the right.
