The standard equation of a circle is given by:
(x-a)²+(y-b)²=r²
where:
(a,b) is the center and r is the radius.
Given that (a,b) is (-8,-3) and r=2 units
then the equation of the circle will be:
(x-(-8))²+(y-(-3))²=2²
simplifying the above we get:
(x+8)²+(y+3)²=4
A:
black,blue
black,red
blue,red
B:
red,black
red,blue
red,green
black,blue
black,green
blue,green
1 centimeter is equivalent to 10 millimeters. So 15x10=150 millimeters.
Hope this helped! :D
Answer:
I'm gonna estimate about 240 miles one way
Explanation:
You have a guide on the bottom right-hand corner of the map that tells you how many miles per that amount of distance. As you can see it is split off into tiles incremented by 30. What you do is take a ruler and measure that guide. For example, let's say the map is 9.5cm and the guide is 2cm per 60 miles. The next thing I would do is to measure the distance in centimeters of the physical map between point a and point b which is 8cm. Finally, I convert the centimeters into miles which is (8/2)*60 = 240.
Answer: You do not need calculus for this problem, as it is currently stated. Is something missing from the problem statement? If not, then just find the difference between the volumes. That will be the additional air required to inflate from the lower volume to the higher volume. For r in inches and V(r) in inches cubed,
V1(r) = (4/3)πr3
V2(2) = (4/3)π(r + 1)3
V2(r) - V1(r) = (4/3)π[(r + 1)3 - r3]
That is your function. You can simplify it further if you wish.
brainliest answer plz
hope this helps BTW
