Step-by-step explanation:
Remark
The first step is the critical one. Take the base and raise it to x. Then take the log of the base and the number whose log you need. x (the power)is brought down and the logs divided.
2^x = 1024
log 2^x = log(1024)
x log(2) = log(1024)
x * 0.30102 = 3.0102
x = 30102/0.30102
x = 10
You could use the e system to solve this as well
2^x = 1024
ln(2^x) = ln(1024)
x * ln(2) = ln(1024)
x 0.6931 = 6.9315
x = 6.9315/0.69315
x = 9.999959
x = 10
Answer:
12
Step-by-step explanation:
multiply 12 by 5 and you get 60
Move the -18 across so that x^2+11x+18<0
then solve as if equal to 0
(x+9)(x+2)<0
x=-9 and x=-2 put these on a graph and it is less than 0 when within the graph hence x>-9 and x<-2
C = total rental cost, m = # of miles you drive, w = # of week you rent
Place #1
C = $10 per week * number weeks + $0.29 per mile * number of miles
C = 10w + 0.29m
Place #2
C = $0.35 per mile * number of miles
C = 0.35m
You’re told you’ll rent it for 3 week, so m=3.
Place #1: C = 10*3 + 0.10m
Place #2: C = 0.35m
Both agencies “charge the same” means the costs are the same. So set the two equations equal and solve for m.
