Answer:
1 comic book costs $3.50.
Step-by-step explanation:
21 ÷ 6 = 3.5
Rate of appreciation is based on an exponential function, i.e.
if r=rate of appreciation, after n years, the new value is
F=P(1+r)^n.
P=present worth
F=future worth.
Here,
P=126000
F=156000
n=8
so
156000=126000(1+r)^8
=>
(1+r)^8=(156000/126000)=26/21
=>
(1+r)=(26/21)^(1/8)=1.02706 (approx.)
=>
r=1.02706-1=0.02706, or
rate of appreciation is approximately 2.7%
Answer:
m = 0 or 5
Step-by-step explanation:
m² − 5m = 0
Factor out m:
m (m − 5) = 0
Set each term to 0:
m = 0
m − 5 = 0
Solve for m:
m = 0
m = 5
Answer:
x=2
Step-by-step explanation:
first divide by 3 left and right, then you get:
x+1 = 3
then subtract 1 left and right, then you get:
x=2
so, solutions appear by simplifying
