2. If f(x) = x – 5 and g(x) = x2 + 3, find f[g(-2)].
irina [24]

Answer:

= 2

Step-by-step explanation:

# g(x) = x^2 + 3 hence g(-2) = (−2)2+3=4+3=7

and so f(g(-2)) = f(7) = 7 - 5 = 2

If Samuel travels twenty kilometers north, fifty kilometers south, and forty kilometers west, what is the approximate magnitude
Gnom [1K]

Answer:

108.75km

Step-by-step explanation:

please find attached the diagram

total displacement can be determined by using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

length of x =

20² + 40²

= 400 + 1600

2000

square root of 2000

= 44.72km

length of y

40² + 50²

1600 + 2500 = 4100

square root of 4100

64.03km

total displacement = 44.72 + 64.03 = 108.75
