Help please. I'll give the Brainliest.
sdas [7]

Answer:

Options 1,2,3 are correct statements

The first values in an ordered pair ( the coordinates) are the domain : ( -3,-2,-1,0,1)

The second values are the range : (-1,1,2,3,4,5)

One input should have only one output for a function.

But -1 input has 2 outputs: -1 and 3.

Thus, it is a relation and not a function.

Hope it helps :)

Mark it Brainliest pls:)

A seller of the property listed at $200,000 excepted a 90% offer the home appraised at $185,000 and the buyers obtained a loan f
Elza [17]

Answer:

$637.50

Step-by-step explanation:

According to the Question,

  • Given That, A seller of the property listed at $200,000 excepted a 90% offer the home appraised at $185,000 and the buyers obtained a loan for 85% for 30 years at 5% interest

Thus, the first months interest is

$200,000 list price x 0.90 = $180,000 contract sales price.

Since lender always uses the less of the appraised value or the contract sales price, use $180,00 for the remainder of the calculations.

  • $180,000 contract sales price x 0.85 LTV = $153,000 loan.
  • $153,000 loan x 0.05 interest rate = $7,650 annual interest.
  • $7,650 ÷ 12 = $637.50 monthly interest payment for the first month.

HELP ASAP how do I solve this problem
puteri [66]
Answer:

C. 5/3 (5 sqrt 3) (8.66...)

Explanation:

You would use the SohCahToa to find out side x.

First, label your sides (10 is hypotenuse, x is the opposite, and blank side is the adjacent).

Second, figure out which part you have to use (Sin, Cosine, or Tangent). A good way to tell is of you have the missing side on top of the fraction, makes things easier.

Third, once you figure that out then plug stuff in...

Sin(theta) = O/H
Sin(60) = X/10
10sin(60) = X
8.66... = X
