A cylinder of radius r cm and height h cm has a curved surface area A cm². Where –
a) We are asked to find formula for h.
First, overturn the equation
Divide both sides by 2πr
b) Again, we are given –
- Curved surface area, A = 93 cm²
- Radius, r = 2.5 cm
- π = 3.1
⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━
- Henceforth, height of the cylinder is 6 cm.
Answer:
If we have a function f(x) that has an inverse g(x), we have the relations:
f( g(x)) = x
g( f(x)) = x
Then if the coordinates for the function f(x) are points like (x₁, y₁)
The coordinates for the inverse, g(x), will be (y₁, x₁)
Now let's look at the table, here we can see that the coordinates for f(x) are:
(0, 650)
(100, 550)
(200, 450)
(340, 310)
(650, 0)
Then the coordinates of the inverse function will be:
(650, 0)
(550, 100)
(450, 200)
(340, 310)
(0, 650)
Step-by-step explanation:
2x2 is 4 4x4 is 16 16x1 is 16
Answer:
-9x
Step-by-step explanation:
Without the confusing parentheses, this "polynomial" becomes -8x + x -2x. If we take 2 away from -8, it becomes -10. If we add a positive x, it becomes -9x. Therefore, the answer is (the monomial) -9x.
