F(x) = 2 * 2 ^x
f(-2) = 2 * 2^-2
f = 0.5
Answer: The correct answer is Volume Cone = one-third pi t squared k
Step-by-step explanation: The first important detail to note here is that both cylinder and cone have the same base and the same height This implies that when writing out the formula for calculating the volume of either of the two shapes, the radius and the height will be the same number or value.
The volume of a cylinder is given as;
Volume cylinder = pi x r squared x h (that is πr²h)
Also the volume of a cone is given as;
Volume cone = one-third x pi x r squared x h (that is 1/3*πr²h)
However, the variables have been changed such that the radius r is now represented by t while the height h is now represented by k.
Therefore the volume of the cone should now be re-written as;
Volume cone = one-third pi t squared k <em>(that is 1/3 *πt²k)</em>
Two whole numbers will end up like this: 8x8=64,but multiplying a whole and a decimal will end up like this 8x8.1=64.1
or 8x8=8 to the second power.
this should be sufficient information.
Answer: of whattt???
Step-by-step explanation:
-10x + 5y = 15
Divide everything by 5.
-10x/5 + 5y/5 = 15/5
-2x + y = 3
So, we can imagine some values to this equality
If x = -1 and y = 1 we have
-2.(-1) + 1 = 3
2 + 1 = 3
3 = 3
Another way we can say:
-10x + 5y = 15
5y = 10x + 15
Divide everything by 5.
y = 2x + 3
So just imagine values to x, let's make 0, 1 and 2.
y = 2.0 + 3
y = 0 + 3
y = 3
y = 2.1 + 3
y = 2 + 3
y = 5
y = 2.2 + 3
y = 4 + 3
y = 7
So, when x = 0, y = 3.
When x = 1, y = 5.
When x = 2, y = 7.
