Answer:
Option A) y = -2x + 15
Step-by-step explanation:
step 1
Find the slope of the line perpendicular to the given line
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
The equation of the given line is
so
The slope of the given line is 
therefore
The slope of the line perpendicular to the given line is
step 2
Find the equation of the perpendicular line in point slope form
we have
substitute
---> equation in point slope form
Convert to slope intercept form
284970469.111 is the answer
Answer:
A greater percentage of blue T-shirts were sold.
see the explanation
Step-by-step explanation:
we know that
To find out the percentage sold, divide the number of shirts sold by the total number of shirts and multiply by 100
so
<em>White t-shirts</em>
total shirts 200
shirts sold 120
<em>Blue t-shirts</em>
total shirts 300
shirts sold 240
Compare
therefore
A greater percentage of blue T-shirts were sold.
V=(1/3)πr²h
∴ dV/dt
=(π/3)[r²(dh/dt)+h2r(dr/dt)]
=(π/3)[(30)²(-2)+40(2)(30)(2)]
=(π/3)[-1800+4800]
=1600π in³/sec
Answer: 1600π in³/sec
