Answer:
extra money earn by typical person earning = $1850
Step-by-step explanation:
earned = $50,000 per year
retained = 2%
credit on their federal tax return = $850
amount of taxes = $850
typical person earning = $50,000
to find out
extra money did a typical person earning receive due to the tax cuts
solution
extra money earn by typical person earning is
extra money earn by typical person earning = 2% of $50000 + $850
extra money earn by typical person earning = $1000 + $850
extra money earn by typical person earning = $1850
Well, negative slope has the word negative in it right? So, it will be the negative number. Answer: -5 (negative 5)
Let x be the shorter side, and y be the longer side
There would be 4 fences along the shorter side, and 2 fences along the longer side
4x + 2y = 800
Rewrite in terms of y:
y = 400 − 2x
The area of the rectangular field is
A = x*y
Replace Y with the equation above:
A = x(400 − 2x)
A = − 2x^2 + 400x
The area is a parabola that opens downward, the maximum area would occur at the parabola vertex.
At the vertex
x = −b/2a
= −400/[2(−2)]
= 100
y = 400 −2x
y = 400 -2(100)
y = 400-200
y = 200
The dimension of the rectangular field that maximize the enclosed area is 100 ft x 200 ft.
