Write the equations:
Substitute for h:
Solve for s:
There were 280 downloads of the standard version. There were 1120 downloads of the high-quality version.
When height turns to 3 times height or 3h
we can replace h with 3h and see what happens
A=1/2b(3h)
A=3/2bh
A=3(1/2bh)
well, the area is trippled
Answer:
(- 1, - 6 )
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 270°
a point (x, y ) → (y, - x ), thus
(6, - 1 ) → (- 1, - 6 )
$20,000
Because 1,000 divided by 5% = 20,000
The equation of a circle with center at (h,k) and radius r is
we are given
center is at (3,2)
solving for y
take the derivitive to find the slope at any point
we can use point slope form
for apoint (h,k) and slope m, the equation is
y-k=m(x-h)
not sure if you want in terms of what
I'll just say for a point (h,k)
so we get
where
that's the equation of the tangent line at (h,k) for arbitrary values of r
do the plots and other stuff yourself
