CP=12, CM=20. CP is the altitude of the triangle. ACP is a right triangle, so you can solve for CP using Pythagorean's theorem. CP=\sqrt(AC^2-CP^2)=\sqrt(15^2-9^2)=12. AM=AP+PM=9+16=25. Triangle ACM is another right triangle, and CM=\sqrt(AM^2-AC^2)=\sqrt(25^2-15^2)=20.
Answer:
midpoint is y2+y1/2, x2+x1/2 therefore 3+1/2,-6+-4/2,4/2,-10/2 and the answer is (2,-5 )
Answer:
Step-by-step explanation:
Given
- f(x) = 2x
- g(x) = x² - 1
- (f - g)(x) = ?
Solution
- (f - g)(x) = 2x - (x² - 1) = 2x - x² + 1 = -x² + 2x +1
- (f - g)(x) = -x² + 2x +1
