Ab=81, a=81/b
s=a+b using a from above in this we get:
s(b)=81/b +b
s(b)=(81+b^2)/b
ds/db=(2b*b-81-b^2)/b^2
ds/db=(2b^2-81-b^2)/b^2
ds/db=(b^2-81)/b^2
d2s/db2=(2b^3-2b^3+81)/b^4
d2s/db2=81/b^4 since b is positive we know that the acceleration is positive so that when ds/db=0 it is a minimum for s(b)
ds/db=0 only when b^2-81=0, b^2=81, b=9
The two positive numbers are 9 and 9.
Add 4 to the right side of the equation to get sex then divide that by 2X and you get 3

Answer:
<em>y = - 4x + 5 </em>
Step-by-step explanation:
y = mx + b
(0, b) y-intercept
m = 
~~~~~~~~~~
( - 2, 13)
(0, <em>5</em>) <----- y-intercept
(3, - 7)
(4, - 11)
<em>m =</em> 
= <em>- 4</em>
<em>y = - 4x + 5</em>
Answer:
<u>10.75%</u>
Step-by-step explanation:
so, you need the total price, which would be 17,850+2,150=20,000 as the whole price of the car, then you need to find what precent 2,150 is of 20,000. then use this formula for finding the precent.
2150/20000 times 100%=10.75%
