Answer:
yes
Step-by-step explanation:
Yes this triangle is right angled and can be justified using the Pythagorean theorem. The theorem states that:
. Substitute using the given values:
(9^2)+(12^2)=15^2
81 + 144 = 255
255 = 255.
It satisfies the theorem therefore it is a right angle triangle.
Step-by-step explanation:
-0.45 = 9/20
2.77= 2 7/9
5.55 = 5 5/9
Answer:
See below...
Step-by-step explanation:
For a function whose formula is in this pattern:

Amplitude: 
Period: 
Phase Shift: C
In this question, 
Amplitude: 4
Period: 
Phase Shift: 
There is no vertical shift, so the midline is the x-axis whose equation is y = 0.
Also, because there is no vertical shift, the maximum is 4 and the minimum is -4.
The graph is attached.
Divide both sides by -5
Sqrt(x) = 3
We want to isolate x to solve for it. The opposite of a square root is a square, so square both sides.
x = 9
It can't be -9 because the square root of negative numbers are not real numbers.
