1.) none are equivalent
2.) J = 1
False, it changes the side length but not the angles.
A^2+b^2=c^2
7^2+15^2=c^2
49+225=c^2
274=c^2
√274 = √c^2
16.55=c
Your missing side is 16.55 units long.
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.
If you would like to know the decimal number which is equivalent to 4/5, you can do this using the following steps:
4/5 = 8/10 = 0.8
The correct result would be 0.8.
