Answer 1

Let x = # of 25-cent stamps

y = # of 2-cent stamps

{   x+ y = 88

{ 0.25x + 0.02y = 15.56

x-intercept 1; y-intercept = 2

Answers

Answer:

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

Step-by-step explanation:

The equation of any (non-vertical) line can take the form

y = ax + b where a is the slope and b is the y intercept. We know that in this case, the y intercept is 2. So we can substitute b = 2:

[tex]y = ax + 2.[/tex]

Now, to find the x intercept, simply put y = 0 (since every point on the x axis has y = 0) and x = -1, since that is the given x intercept:

0 = -a + 2, so we see that a = 2. The equation is then:

y = 2x + 2

A college student takes out a $7 500 loan from a bank. Assuming the student has not started paying back the money, how much does the student owe . . .

1.1 . . . after 1 year, if the bank charges 3.8% interest each year?

Answers

The key to these questions is to understand the compounding. In this case, they are telling you the banks compound annually.

So the time period in the compounding equation is YEARS.

The compounding equation is:


(Future Loan Amount) = (Current Loan Amount) * (1 + the interest rate of the time period in decimals) ^ (number of time periods)


(Use this for all future questions too - if compounding monthly then time period is total number of months and interest rate is annual rate divided by 12 etc)


So in this case the answer is:


(Future Loan Amount) = (Current Loan Amount) * (1 + the interest rate of the time period in decimals) ^ (number of time periods)


(Future Loan Amount) = $7,500 * (1 + 0.038) ^ (11) = $11,304


(note - when answering its hard to see the original question. I believe the answer asked for 11 years. If not, if 1 year, etc just plug in that number into the equation - so one year is simply: 7500*1.038 = $7,785

Susan is an interior floor designer. When designing a new floor, she uses a coordinate grid to

represent the room. The client wants a rectangular tile insert in the floor of the room. The

coordinates for 3 of the corners of the insert are A (-7,-4), B (1,6), and C (6,2).

YA

Answers

A rectangle has 4 coordinates.

The coordinate of the last vertex is (-2,-8)

The points are given as:

[tex]\mathbf{A = (-7,-4)}[/tex]

[tex]\mathbf{B = (1,6)}[/tex]

[tex]\mathbf{C = (6,2)}[/tex]

Calculate distance AB

[tex]\mathbf{AB = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}}[/tex]

So, we have:

[tex]\mathbf{AB = \sqrt{(-7 - 1)^2 + (-4 - 6)^2}}[/tex]

Calculate distance CD

[tex]\mathbf{CD = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}}[/tex]

So, we have:

[tex]\mathbf{CD = \sqrt{(x - 6)^2 + (y - 2 )^2}}[/tex]

Equate AB and CD

[tex]\mathbf{ \sqrt{(x - 6)^2 + (y - 2)^2} = \sqrt{(-7 - 1)^2 + (-4 - 6)^2}}\\[/tex]

Cancel out the squares

[tex]\mathbf{ (x - 6)^2 + (y - 2)^2 = (-7 - 1)^2 + (-4 - 6)^2}[/tex]

By comparison

[tex]\mathbf{x -6 = -7-1}[/tex]

[tex]\mathbf{y-2 = -4-6}[/tex]

So, we have:

[tex]\mathbf{ x = 6-7-1 }[/tex]

[tex]\mathbf{ x = -2}[/tex]

[tex]\mathbf{y = 2-4-6 }[/tex]

[tex]\mathbf{y = -8}[/tex]

Hence, the coordinate of the last vertex is (-2,-8)

Answer: (-1, 14) and (-8, 75)

Plug in the numbers and see if it’s true. We know that the x intercept is in the front and the y intercept is in the back.

(x,y)

So with the first choice the x = -1; y = 14

14 > -10(-1) -1

14 > 9

So this is an answer

Do the same with every choice and see what works

Find the Area. Use 3.14 for pi

Answers

Answer: 36.56

Step-by-step explanation:

To solve the equation, first acknowledge that the radius of the quarter circle shown at the top of the figure is 4 cm, so the rectangle's dimensions are 4 by (10-4) or 4 by 6, meaning the area is 24 cm^2.

Then address the circle, with an area of pi * r^2.

pi * r^2

3.14 *(4)^2

3.14 * 16

50.24

Then, because the figure shows 1/4 of a circle, divide 50.24 by 4.

50.24/4

12.56

Then add 24 to 12.56 to get 36.56.
