Answer:
6.71
Step-by-step explanation:
From Pythagoras theorem, we know that;
x^2 = 6^2 + 3^2
x^2 = 36 + 9
x^2 = 45
x = sqrt(45)
x = 6.71
Are you looking for the solution of x, y, or the equation??
Answer:
yes
Step-by-step explanation:
10 separated into 5 groups is 10/5
5 goes into 10 2 times.
10/5=2
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.
