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.
Answer: 2
Explanation:
The average rate of change is the net change of the function, i.e. final value less initial value, divided by the interval:
f(b) - f(a) f(1) - (f(-3)
average change rate from a to b = ---------------- = ---------------
b - a 1 - (-3)
f(1) = -(1/2) (1 + 2)² + 5 = -(1/2) (3)² + 5 = 5 - 9/2 = 1/2
f(-3) = -(1/2) ( -3 + 2)² + 5 = -(1/2) (-1)² + 5 = 5 - 1/2 = 9/2
(1/2) - (9/2)
average change rate = -------------------- = 2
1 - 3
That is the answer.

Answer:
The answer to this is C. The dinosaur is about 5 feet taller than the person.
Step-by-step explanation:
The reason why is because the human is 4 feet since it says that 1/2 inch on the scale is 2 feet and the human is 1 inch on the scale so the human is 4 feet.
The dino is 8 feet since it goes to 2 inches on the scale which means 8 feet. The difference between 4 and 8 is 4, so 5 feet is the approximate for this problem.
<span>Player 1 jump than Player 2 i know this because if you look at the problem twice you see the 0.9 is bigger then 0.8</span>
