Answer:
27
Step-by-step explanation:
Replace the x in f(x) by g(x) to get (f o g)(x)
= 2(4x - 3) - 7
= 8x - 6 - 7
= 8x - 13
so (f o g) (5)
= 8(5) - 13
= 27
Answer:
8.6 meters
Step-by-step explanation:
a² + b² = c² means leg² + leg² = hypotenuse ²
5² + 7² = hypotenuse²
25 + 49 = hypotenuse²
74 = hypotenuse ²
= hypotenuse
8.6 = hypotenuse
-1/3w = 5 3/8
-1/3w = 43/8
w = (43/8) / (-1/3)
w = (43/8) (-3)
w = -129/8
w = - 16 1/8
