In the diagram below AH, AD, and DH are each tangent to circle Q.AT=9,AH=13, and AD= 15 what is HD

If f(2) = 5, f(3) = 2, f(4) = 5, g(2) = 6, g(3) = 2 and g(4) = 0, find (f · g)(2) + f(g(3)). ... f(x) = { c2x − c x ≤ 1 cx − x x > 1. Solution. The partial functions of f(x) are continuous for x < 1 and x > 1 ... 5 , we have f (x) = 5. 3 x. 2. 3 +. 6(−3. 5. )x−8. 5 = 5. 3√ x2. 3. − 18. 5. 5√ x8 . 8. ... x2 − 2x = −1 =⇒ (x − 1)(x − 1)=0=⇒ x = 1.
