Answer:
f(x) = 10(10)+3 = 103 when x = 10
Step-by-step explanation:
Given a function piecewise as
f(x) = 2x-4 if -3<x<10
= x^2+3, if 10<=x<13
We see from the definition of f(x) that the function has domain as (-3,13) and two sets defined from (-3,10) and [10,13).
Since 10 less than or equal to sign is there in the second function interval, we find that 10 is included in that.
Hence for finding f(10) we use the function defined for interval including 10 i.e. x^2+3
Substitute 10 for x in x^2+3
f(10) = 10^2+3
=103
Hence answer is 103
Answer:
$57.60
Step-by-step explanation:
Marcus lays a slab of concrete in 3 hours. Tony lays the same size slab in 2 hours. The number of hours used by both men will be:
1/3x + 1/2x = 1
2x + 3x = 6
5x = 6
x = 6/5 = 1.2 hours.
The cost of labor will be:
= 1.2 hours × $48
= $57.60
