Y = -5x -5
To check, we can insert 0 for y and -1 for x
0 ? (-5X-1) - 5
0 ? 5 - 5
0 = 0
So yes, the equation is correct
Let
v-------> <span> the volume of a sphere
s-------> t</span><span>he surface area of the sphere
r------> </span><span>the radius of the sphere
we know that
v=(4/3)*pi*r</span>³-----> v=(r/3)*4*pi*r²------> equation 1
and
S=4*pi*r²-----> equation 2
substitute equation 2 in equation 1
so
v=(r/3)*4*pi*r²-------> v=(r/3)*s
the answer is
the equation that <span>represents the relationship between these three measures
</span> v=(r/3)*s
32, 60, 68

Solving the quadratic function, it is found that the range is of:
between 200 and 250; inclusive
The profit for x tours is modeled by the following equation:

It is concave down, so the monthly profit will be of at least $60,000 between the two roots when
. Thus:


Simplifying by 2:

Which has 
Then:

At least $60,000 includes $60,000, thus the interval is inclusive, and the correct option is:
between 200 and 250; inclusive
