Read my note at the end of problem 5 in another post.
You already know this table represents an exponential function
since each y-coordinate is always the previous y-coordinate multiplied by 6.
That means b = 6, and you have
y = a(6)^x
Now we find "a". When x = 0, y = 5. That means a = 5.
The equation is
y = 5(6)^x
The answer is (7/9, -5/9)
(7 over 9 and negative 5 over 9)
Answer- 42646.50 pounds
Area of flat surface = Area of rectangle + area of triangle
= 12.9*25 + 1/2* 7.2* 25
= 162.5 feet^2
Force exerted by wind =0 .004 * Area * velocity^2
= 42646.50 pounds
Brand A has a unit price of .37 cents
brand B has a unit price of .38 cents
so you get 2 more pencils for .1 cent each, so brand B is the better deal
