Answer:f=12.96
Step-by-step explanation:
f(-4.2)=3.25(-4.2)+22.41
f(-4.2)=-13.65+22.41
f(-4.2)=8.76
f=12.96
You can solve this problem with one variable, x.
If the helicopter flew 34 times on Friday, and an equal number of times on Saturday and Sunday, then you can use the equation:
34+2x=118
2x=84
x=42
The answer is B.

Explanation

where x is the number of days since the start of the job
and f(x) is the rate of change
Step 1
a)find the total expenditure if the job takes 12 days
so, as x represents the number of days, just replace and calculate
let x= 12

so
a) 51.1
Step 2
now, let's find the total spent on the job from the 10 to 20th day
a) find the x value ( number of days since the job started)
x= 20 days-10dys= 10
so
x= 10
