Solve for q. k = 4pq²

Sergeeva-Olga [200]

k = 4pq^2 //Divide both sides by 4p

k/4p = q^2 //Square root on both sides

+- √(k / 4p) = q

q = √k / 2√p and - √k / 2√p

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.
