Answer: Each age is 12 more than the last so the rate of change would be twelve. Yes it is linear, every twelve pounds is 2.5 more millimeters of dosage.
We have to use the function A(t)= a(1 +/- r)^t
So A is going to be the answer- the area after 8 years. t is going to be 8, because t is time. a is 2400 because that's the starting value. Finally, we're going to turn 5.75% into it's decimal form of .0575. That's going to be r, and because the area is decreasing, we will subtract r from 1.
Our new function is:
A=2400(1-.0575)^8
Simplify a little bit.
A=2400(.9425)^8
Bring .9425 to to power of 8 and then multiply by 2400 because PEDMAS.
A=1494.38366866
The rounded answer is 1494 kilometers squared.
Important: represent your unknowns. You might represent "number of adult tickets sold" by "a" and "number of student tickets sold" by "s."
How many tickets were sold, altogether? Express this sum algebraically, using "a" and "s."
How does the number of student tickets sold compare with the number of adult tickets sold? Express this algebraically in therms of "a" and "s."
<span><span>Yes, it meets the requirements. 1/12 simplifies to 0.0833 and 4/50 simplifies to .08. .</span>413398#respond</span>
