Answer:(15, 100)
Step-by-step explanation:
first find the coordinates of the point above (3, 20)
you just look at the x axis and where the point is in this case x would be 6 and then you find y which would be 40
so the coordinate would be (6, 40)
now subtract (6, 40) by (3, 20)
6-3= 3
40- 20= 20
you get the first coordnites which is what you add (12,80) to
12 +3= 15
80+ 20= 100
you get the coordinates (15, 100)
0.32323232323
I really dont got a stratgie im sorry if im wrong have a good day
I assume it is asking for the surface area of a cylinder. A cylinder is composed of 2 parts. It has 2 circles and one rectangle. So lets solve for the circles:
The area is πr^2. Given our radius, 2, we can substitute into our r.
That gives us 4π. But since we have two circles, it is 8π
Next we solve for our rectangle. Our height is 4 and our base is 2πr or 4π
4 * 4π = 16π
Finally we add.
We get 16π + 8π = 24π ≈ 75.398 cm^2
Answer:
Just 1
Explaination:
If one line has a positive slope and the other a negative slope, they are bound to intercept eventually, so that's why there can't be zero solutions. Two lines can't intercept each other twice, and if they have opposite slopes they can't have infinite solutions.
