What is the length of the unknown side?
777dan777 [17]

Answer:

Hi there!

The correct answer is: 20

Step-by-step explanation:

knowing this a right triangle you can solve this problem in two ways

Method One: Pythagorean Theorem

a^2 + b^2 = c^2 then plug in the values

(12)^2 + (16)^2 = c^2 this will come out to be 400 = c^2

square root both sides and you get c = 20

Method Two: Pythagorean Identities

if you ever learned the Pythagorean identity 3,4,5

this triangle is indeed a 3,4,5 triangle it's just that each side is multiplied by the factor 4

so in this case since you know the missing side should be 5 you just multiply 5 by 4 and you get 20

In the summer of 2014, the average listing price for homes for sale in the Hollywood Hills was $2,663,995.
Wewaii [24]

Answer:

  • monthly payment: $15,903.61
  • interest: $2,368,664.10

Step-by-step explanation:

a) The loan amount is 90% of the price shown, so is ...

  0.90 × $2,663,995 = $2,397,595.50

The monthly loan payment is given by the amortization formula:

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

  A = $2,397,595.50(0.0525/12)/(1 -(1 +0.0525/12)^(-12·30))

  A = $13,239.61

The monthly escrow payment will be 1/12 of the annual amount:

  0.012 × $2,663,995 / 12 = $2664.00

So, the total monthly payment on the house will be ...

  $13,239.61 +2664.00 = $15,903.61

__

b) The sum of monthly loan payments is ...

  $13,239.61 × 360 = $4,766,259.60

so the interest on the $2,397,595.50 loan is ...

  $4,766,259.60 -2,397,595.50 = $2,368,664.10

ANSWER

D. A'(-5,0), B'(0,9) and (2,6)

EXPLANATION

The coordinates of triangle ABC are A(0,-5), B(-9,0) and C(-6,2).

A rotation of 90° clockwise about the origin has the mapping,

(x,y)\to (y,-x)

Therefore the image triangle has vertices

A'(-5,0), B'(0,9) and C'(2,6)

The correct choice is D.
