Please Help Meeeeee, Amanda's house is due west of Stamford and due south of Newport. Stamford is 12 kilometers from Amanda's ho
lubasha [3.4K]

Answer:

  5 km

Step-by-step explanation:

It helps to draw a diagram.

The triangle between Stamford, Newport, and Amanda's house is a right triangle with one leg of length 12 and hypotenuse 13. The Pythagorean theorem can be used to find the remaining leg:

  13² = 12² + (distance to Newport)²

  169 -144 = (distance to Newport)²

  √25 = 5 = distance to Newport

Newport is 5 km from Amanda's house.

_____

It can be useful to remember this right triangle. 5-12-13 right triangles show up in a number of algebra and geometry problems.

Find the area of the isosceles triangle.​
Allushta [10]

Answer:

60in^2

Step-by-step explanation:

Area of a triangle = Height x Base X 1/2

Base = 10

Other 2 sides = 13

Now, let's split the Base into 2 parts.

=> 1 part = 5 and 2 part = 5

We can find the height using Pythagorean theorem

=> Isosceles triangle

=> (1 part of the base)^2 + Height^2 = The Hypotenuse^2  = the longer side of a triangle = 13^2

=> 5^2 + Height ^2 = 13^2

=> 25 + Height^2 = 169

=> 25 - 25 + Height ^2 = 169 - 25

=> Height^2 = 144

=> Height = Square root of 144

=> Height = 12

Area = 12 x 10 x 1/2

=> 12 x 5

=> 60 in^2

So, the Area is 60 in ^2

You pay 3.5% annual simple interest for 12 years on a loan, and you pay $1,512 in interest. How much is the principal?
Anika [276]
A = Pe^rt
Amount of interest paid = Principal*e^ (rate*time)
(The rate must be in decimal form)
3.15% / 100 = .0315

1,512 = P[e^(.0315*12)]
1,512 / e^(.0315*12) = P
1036.06 = P
$1036.06 was the Principal
** I left that value unrounded to the hundreds place because one doesn’t round with money. :)

Good luck!
