Answer:
90, there are 32 ninetys in 32 X 90 and there are 33 ninetys in 33 X 90, meaning there is one more 90 in 33 X 90 than 32 X 90
Answer:
31,250 ft²
Step-by-step explanation:
Let x represent the length of fence parallel to the river. Then the ends of the rectangle will have dimesion (500-x)/2, and the total area will be ...
... A = x(500-x)/2
This function describes a parabola with zeros at x=0 and x=500. The vertex (maximum) will be located halfway between these, at x=250.
The maximum size pen has area ...
... A = 250(500 -250)/2 = 31,250 . . . . sq ft
If the y-intercept is at -69, meaning the point is (0, -69), thus x = 0, y = -69

Divide both side by
and rearrange terms to get a linear ODE;

Multiply both sides by
:

The left side can be condensed as the derivative of a product:

Integrate both sides, then solve for
:

Answer:
Step-by-step explanation:
Proportional relationship means,
x ∝ y
x = ky
where 'k' is the proportionality constant.
From table (1),
Therefore, relationship is not proportional.
From table (2),

True.
So the relationship will be proportional.
From table (3),

Which is constant.
Therefore, relationship will be proportional.
From table (4),

Which is constant for every term.
Therefore, relationship will be proportional.
