Answer:
Well it varies for how many lines you put on the graph, if you use desmos the answer comes out as 40 units; 25 units to the right of (-4,1) and 20 down
Step-by-step explanation:
Answer:
100, because 180 - 50 - 90 = 40
The vertical angles theorem is applied, so now angle DCE is 40
And since CE = ED, its isosceles triangle, so base angles are equal, so 40 and 40.
180 - 80 = 100 = Angle E.
Answer with Step-by-step explanation:
We are given that displacement of wave

Where y in cm and t in sec.
a.Compare it with

Amplitude of wave=A
We get A=1.5
Amplitude=A=1.5 cm
b.k=0.68


Using 
Wavelength of the wave=9.2 cm
c.Period=


The period of the wave=0.17 s
Speed of the wave=
Speed of the wave=54.1 cm/s
Answer:
D. All of these
Step-by-step explanation:
Requirements determination is the process of transforming a system's request into more detailed business statement that is clear and precise. It is the beginning sub phase of analysis, so all the given options in the question can be included.
4. Then you have x^2+4x+4 which gives you (x+2)(x+2) when you factor it.
