3,868,000,000 in scientific notation is 3.868*10^9
Answer:
y = 9 - 5x
[x = -1] 14
[x = 0] 4
[x = 4] -11
Step-by-step explanation:
Step 1: Define
y + 5x = 9
x = -1, 0, 4
Step 2: Solve for <em>y</em>
y = 9 - 5x
Step 3: Plug in values of <em>x</em>
y = 9 - 5(-1) = 14
y = 9 - 5(0) = 4
y = 9 - 5(4) = -11
Answer:
a) 16
b) Using is more accurate because it represents the exact and full value of pi, rather than an estimation or approximation like 3.14.
Step-by-step explanation:
The formula to find the volume of a cone is . We know the radius is 6, so all we need to find is the height, h. By using the Pythagorean theorem, we can see that the height is , or 8. Plugging in all the values into the formula gives us:
V =
V = 16
