GEOMETRY QUESTION, HELP PLEASEEE.

Answers

Answer 1

Answer:

The pre-image C is (2, 5)

Step-by-step explanation:

If the point (x, y) rotated about the origin by angle 90° clockwise, then its image is (y, -x)If the point (x, y) rotated about the origin by angle 180° clockwise, then its image is (-x, -y)If the point (x, y) rotated about the origin by angle 270° clockwise, then its image is (-y, x)

∵ Point C was rotated 270° clockwise around the origin

∵ C' = (-5, 2)

→ By using the 3rd rule above

∵ The image of the point (x, y) is (-y, x)

∴ (-y, x) = (-5, 2)

→ That means -y = -5 and x = 2

∴ x = 2

∴ -y = -5

→ Divide both sides by -1

∴ y = 5

∴ The pre-image C = (2, 5)

a waterslide has an angle of elevation of 20 degrees whats is the rise for a run of 2.6 m?

Answers

Answer:

Therefore, the rise will be 0.95 m

Step-by-step explanation:

As the waterslide has an angle of elevation of 20 degrees.

Ф = 20°

And we have to determine the rise for a run of 2.6 m.

All we need is to use the trigonometric ratio of tan Ф

Because

tan Ф = rise/run

run = 2.6 m

Ф = 20°

tan Ф = rise/run

tan (20) = rise/run

rise = tan (20) × 2.6

rise = 0.95 m

Therefore, the rise will be 0.95 m

x+5y=20
x+3y=14

x=
y=

Answers

Answer:y = − 1 5 x + 4

Step-by-step explanation:

Do elimination
x + 5y = 20
x + 3y = 14
Subtract both equations
2y = 6
y = 3
Plug in 3 for y and solve for x
x + 5(3) = 20
x + 15 = 20
x = 5
In conclusion, x = 5, y = 3

Which equation best describes the line in the graph?

Answers

Answer:b

Step-by-step explanation:

Give brainliest

Answer:

Step-by-step explanation:

The question is looking for an equation in slope-intercept form which is y=mx+b where m is the slope and b is the y-intercept. The y-intercept is +4, which all of the answers show, so you must find the slope.

The slope is the change in y over change in x, more commonly referred to as rise over run. So count how many units the graph changes vertically and horizontally, in this case, 1 up and 2 right, so the slope is equal to 1/2. If you have a graph where the line shifts up and left, or down and right, then the slope is negative. Additionally, one way to visually check your work is to remember slopes equal to less than -1 or greater than +1 will be steeper while fraction slopes will make the slope flatter; basically the closer to zero the less steep.

Paying off a consumer loan prior to its maturity Paying Off Installment Loans Some installment loans include terms that charge a penalty if the borrower pays off the loan earlier than its maturity date. The specific terms can vary so its important to know if a loan youre considering provides for a prepayment penalty and if it does, what its exact terms are. A common way to compute a penalty is the sum-of-the-digits method. You and your friend recently took out installment loans. You expect to pay off your loan before its maturity date, so you made sure that the contract: Provides for the use of the Rule of 78s Does not contain a prepayment penalty clause Provides for the use of the sum-of-the-digits method Your friend didnt anticipate being able to pay off the loan before its maturity dateuntil he won a lot of money in the lottery, enough to pay it off. He decided to pay off the loan today rather than invest his winnings. Whats the most likely reason why? The loan contract would use the sum-of-the-digits method to compute interest if your friend paid off the loan before its maturity date. The interest rate on the loan is lower than the rate of return your friend would earn on his investment. The contract does not contain a prepayment penalty clause. True or False: Computing interest using the sum-of-the-digits method allocates more interest at the beginning of a loan than at the end of the loan.
