Answer:
A)94.5 cm
Step-by-step explanation:
height = 9cm
Base 1 = 5cm
Area of a Trapezoid = 1/2 × (b1 + b2)h
h = 9cm
b1 = 5cm
b2 = (9 cm + 5cm + 2cm) = 16cm.
Area of Trapezoid
= 1/2 (5 + 16) × 9
= 1/2 × 21 × 9
= 94.5 cm
Option A is the correct answer
So we multiply both sides by 7 to make 2/7 a whole number. You get 2(4q+7/2)-21q=63. Then take 4q+7/2 out of parentheses and you get 8q+7-21q=63. Subtract 7 on both sides and add the q’s together, -13q=56. Divide both sides by -13 and you get around 4.3
247,000
Because the number to the right of the seven is a 0.

![\frac{dy}{dx}=-[(\frac{5x+24}{36x-6x^2})]](https://tex.z-dn.net/?f=%5Cfrac%7Bdy%7D%7Bdx%7D%3D-%5B%28%5Cfrac%7B5x%2B24%7D%7B36x-6x%5E2%7D%29%5D)
Step-by-step explanation:
Given function:
y =
we know
= ln(A) - ln(B)
thus,
y = 
or
also,
ln(Aⁿ) = n × ln(A)
thus,
y = 
therefore,
![\frac{dy}{dx}=[(\frac{3}{2})\times\frac{1}{(6-x)}\times(0 - 1)] - [ (\frac{2}{3})\times\frac{1}{x}\times1]](https://tex.z-dn.net/?f=%5Cfrac%7Bdy%7D%7Bdx%7D%3D%5B%28%5Cfrac%7B3%7D%7B2%7D%29%5Ctimes%5Cfrac%7B1%7D%7B%286-x%29%7D%5Ctimes%280%20-%201%29%5D%20-%20%5B%20%28%5Cfrac%7B2%7D%7B3%7D%29%5Ctimes%5Cfrac%7B1%7D%7Bx%7D%5Ctimes1%5D)
