Answer: yes it is a right angle triangle
Step-by-step explanation:
a^2 + b^2 = c^2
8^2+ 5^2 = ?
64 + 25 = square root of 89
square root of 89 = 9.4
when we round 9.4 it is 9
so
22- (8+5) =
22 - 13 = 9
so our answer is correct
The central angle AOC subtended by arc AC has measure equal to 46% of a complete revolution, or , so .
Answer:
D. 4 23/24
Step-by-step explanation:
1 7/8 = 1 21/24
6 5/6 = 6 20/24
6 - 1 = 5
20 - 21 = -1
5 - 1/24 = 4 23/24
Answer:
Domain: all real numbers
Step-by-step explanation:
This graph is a parabola. It's equation looks like it should be:
y = x^2 - 1
If you have a graph and are looking for the domain, you are determining where the graph exists. For what x's the graph exists. If you have the equation then the domain is what x's may be put into the equation. There are no limitations on what numbers can go into this equation so the domain is all real numbers.
There are several ways to write the domain is all real numbers, set builder notation and interval notation. But the main idea is that it is all real numbers.
Answer:
Below in bold.
Step-by-step explanation:
y = 2x²-4
First find x in terms of y:
2x² = y - 4
x² = (y - 4)/2
x = √ [(y - 4)/2]
Now replace x by the inverse f-1(x) and y by x:
f-1(x) = √ [(x - 4)/2] (Note: it's the positive square root only)
