$\text{Apply Pythagorean theorem,}\\ \\~~~~~~12^2 = 3^2 + h^2\\\\\implies h^2 = 12^2 -3^2\\\\\implies h^2 = 144-9\\\\\implies h^2 = 135\\\\\implies h = \sqrt{135}\\\\\implies h = 3\sqrt{15}\\\\\implies h \approx 11.62$

What is the length, in meters, of the ramp, line segment AC, below? Round to the nearest whole number if necessary.

Brrunno [24]

10 meters.

Step-by-step explanation:

To find the missing side of a right triangle, we can use the Pythagorean theorem.

The Pythagorean theorem is...

$a^2+b^2=c^2$

Please be sure to note that a and b will always be the length of the sides and c will always be the hypotenuse, or in this case the ramp.

Since we know the values of both of the sides we can plug this into the theorem.

$6^2+8^2=c^2$

Now we can solve.

$36+64+c^2$

Add.

$100=c^2$

Many people will make the mistake of thinking 100 is the final answer, but since c is squared we need to find the square root of 100.

$\sqrt{100} =10$

c = 10

The ramp is 10 meters.

Amy purchased a house for $551,000 and obtained a mortgage for $519,000 she purchased 3 discount points and 2 origination points

Olegator [25]

Discount points are normally a type of prepaid interests that lowers the interest on subsequent payments for mortgage borrowers pay.

Each of the points is given by:

1 point = 1% of the mortgage value.

Therefore,
Cost of discount points = 0.01*519,000*3 = $15,570
Cost of origination points = 0.01*519,000*2 = $10,380

In this regard, option B. is the correct answer on the cost of discount and origination points respectively.
