Lna^b = blna
let y = lne^e
so y = lne^e = e lne
lne = 1
y = e which is a constant (Euler's number) ~= 2.718
For Euler's number estimating methods request in a comment.
Answer:
2%
Step-by-step explanation:
Find the sales tax rate by dividing the amount of sales tax by the original cost:
6.40/320
= 0.02
So, the sales tax rate is 2%
F(x) = x + 3
y = x + 3
x = y - 3
Inverse is h(x) = x - 3
Answer:
t ≥ 18
Step-by-step explanation:
He has run 12 miles plus some more miles t. He need to run at least 30 miles
12+t ≥ 30
Subtract 12 from each side
12+t-12 ≥ 30-12
t ≥ 18
Answer:
x=50/3y
y=50/3x
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
