Answer:
10408 ft
Step-by-step explanation:
convert miles to ft
4 miles/hr * 5280 ft/ mile = 21120 ft/hr
convert hr to min
21120 ft/hr * 1hr/60 min = 352 ft/ min
multiply by 40 minutes
352 ft/min * 40 min =14080 ft
First we need to calculate t(4) because x=4 for 4 shifts.
t(4) = 4*4 +3 = 19
Now because function "c" is declared as c(t(x)) for value x=4 we are searching c(19)! because t(4) = 19
c(19) = 2*19 + 5 = 43.
Answer is 43
The first one is -763.1 and the second one is -24
X. Y
12 —> 4
8 —> 8/3
13 —> 13/3
Substitute x values for y.
y = 1/3(12)
y=4
