Answer:
I BELIVE IT IS -2
Step-by-step explanation:
Answer:
41.9 units³
Step-by-step explanation:
(please see attached for reference)
The volume of a cone is given by:
V = (1/3) πr²h where,
V = volume (we are asked to find this)
π = 3.142
r = radius = given as 2
h = height = given as 10
Substituting the known values into the above equation,
V = (1/3) πr²h
= (1/3) (3.142) (2²)(10)
= 41.893
= 41.9 units³ (nearest tenth)
Answer:
- domain (-∞, ∞)
- range (-∞, 4]
- increasing (-∞, 0)
- decreasing (0, ∞)
- constant (only at x=0, not on any interval)
Step-by-step explanation:
The graph is of the equation y = -x^2 +4. It is a polynomial of even degree, so has a domain of all real numbers: (-∞, ∞).
The vertical extent of the graph includes y=4 and all numbers less than that:
range: (-∞, 4]
The graph is increasing to the left of its vertex at x=0, decreasing to the right.
increasing (-∞, 0); decreasing (0, ∞)
There is no interval on which the function is constant. It has a horizontal tangent at x=0, but a single point does not constitute an interval.
