Answer: 12 inches
Step-by-step explanation: In this problem, since we're asked to find the length of the median, let's use our formula for the area of a trapezoid that involves the median which is shown below.
Area = median · height
We know that the area is 144 and the height is 9 so we can set up the equation 144 = M · 12. Now to solve for <em>m</em>, we divide both sides of the equation by 12 and we find that 12 = M.
So the length of the median of the trapezoid is 12 inches.
Answer:
Step-by-step explanation:
let width=x
length=3x
area=3x×x=3x²
3x²=192
x²=192/3=64
x=√64=8
width=8 m
length=3×8=24 m
ANSWER
An exponential growth function.
EXPLANATION
The given function is
This function is of the form,
Since k is positive , the function will grow exponentially and fall asymptote to the negative x-axis.
As x-values becomes bigger and bigger positively, the graph grows exponentially.
Answer:
x=25.5
Step-by-step explanation:
Lets do math:
Look we can do this: we can substitute f(x) with 6 because thats what the second equation says. So we get this equation.
6=2x+61-4
-6 -6
0=2x+61-4-6
0=2x+51
2x=-51
x=-25.5
The end
The amount that you get from rocking chairs is $100 × r which is $100r
and the amount that you gt from bar stools is $40×b which is $40b
The total amount will be the added amount of 100r + 40 b
so answer is 100r+40b
