Answer:
-1
Step-by-step explanation:
The given function, f(x), has three distinct parts. We must find and choose the part whose domain includes x = 1.
This x = 1 is a member of the set 1 ≤ x < 2. Therefore, we choose the 2nd part of this function: evaluate -x^2 at x = 1. This comes out to -1^2, or -1. that's the second answer choice.
the units of measurement for the composite function f(w(h)) are - furniture/weeks
<h3>
What are composite functions?</h3>
function composition is an operation. that takes two functions f and g, and produces a function h = g . f such that h(x) = g. In this operation, the function g is applied to the result of applying the function f to x.
- Let as consider the work f(t) approximates how numerous pieces of furniture he paints per hour.
- It implies unit of this work is furniture/hours. The work w(h) speaks to how numerous hours per week Joey spends portray the pieces of furniture.
- It implies unit of this work is hours/weeks. We have to be discover the units of estimation for the composite work f(w(h)).
- It the work f(w(h)), to begin with we ought to apply the work w(h) after that f(t).
The units of measurement for the composite function f(w(h)) is furniture/weeks.

Answer:
C, 18
Step-by-step explanation:
<span>160 minutes.
The formula for Kristi's bill is (6.95 plus 0.07 per minute for a total of 18.15)
6.95 + 0.07m = 18.15
Subtract 6.95 from both sides
0.07m = 11.20
Divide both sides by 0.07
m = 11.20 / 0.07 = 160
So Kristi used 160 minutes.</span>
