Answer:
- 2
Step-by-step explanation:
f(2) = - 2
The ratios of bats to balls would be the number of bats over the number of balls:
15/12
This can be reduced because both numbers are multiples of 3, so divide each one by 3:
15/12 = 5/4
Answer: 5/4
p = 3r + 2s
p - 3r = 2s <em>subtract 3r from both sides</em>
(p - 3r)/2 = s <em>divide both sides by 2</em>
Answer: (p - 3r)/2
A’s increase is 1.8/1.5=6/5; B’s increase is 1/0.6=5/3.
A formula for A is A(t)=1.5(6/5)^t and for B, B(t)=0.6(5/3)^t where t is years since 2004.
When A=B, 1.5(6/5)^t=0.6(5/3)^t.
Taking logs: log1.5+tlog(6/5)=log0.6+tlog(5/3), t(log(5/3)-log(6/5))=log1.5-log0.6.
tlog(25/18)=log2.5, t=log2.5/log(25/18)=2.7893 approx.
This occurs during 2006 around mid-October.
Common sales=1.5(6/5)^2.7893=0.6(5/3)^2.7893=$2.4943 billion.
