Answer:
Yes
Step-by-step explanation:
To determine if this is a right triangle, use the pythagorean theorem and see if a^2 + b^2 is equal to c^2.
a^2 + b^2 = c^2
12^2 + 16^2 = 20^2
Evaluate the exponents.
144 + 256 = 400
Add them together.
400 = 400
Since a^2 and b^2 add up to equal c^2, this is a right triangle.
Answer:
D = √[(x2 - x1)² + (y2 - y1)²]
Step-by-step explanation:
Given a right-angled triangle, with sides: Hypotenuse D, and opposites (x2 - x1) and (y2 - y1).
Then by Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the opposite side.
That is,
D² = (x2 - x1)² + (y2 - y1)²
Now, taking square roots of both side, we have the formula for the distance or length D.
D = √[(x2 - x1)² + (y2 - y1)²]
Answer:
B
Step-by-step explanation:
5% of 500 is 25
if the interest rate is $25 every month so it will take 20 months to earn $500

good luck
