f(x) = log2 x
f(40) = log2 40
40 = 2^y
2^5 = 32 and 2^6 = 64
so f(40) lies between integers 5 and 6.
Answer:12
Step-by-step explanation:
The range is simply the highest number minus the smallest number. Since we are told that 2 members of the family have shoe size of 7 and the range is 5, then Melissa shoes size will be:
= 5 + 7
= 12
Answer:
x = 1/9.
Explanation:
-4(2x - 5) – (7 – 3x) = 4(x + 3)
-8x + 20 - 7 + 3x = 4x + 12
-8x + 3x - 4x = 12 + 7 - 20
-9x = -1
x = 1/9.
Answer:
You can travel 790 miles in one week for $328.50.
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
