Y=2cos3x How do I graph this with labels in radians

Mathematics
1 answer:
aleksandrvk [35]3 years ago
3 0

Answer:

Linked an image

Step-by-step explanation:

Okay, basically since it is y=2co3x you know that the amplitude is 2, so rather than going to +1 and -1, you now go to +2 and -2.  Since it's cosine, you also know that you start at the maximum rather than the intercept, so the starting point is at (0,2).  

I'm assuming that you need to graph 2 periods, and to find the periods you divide 2pi/b, so, in this case, 2pi/3

Then lastly you need to find the four points between 0 and 2pi/3, so you divide 2pi/3/4 to get 2pi/12=pi/6

If you have any other questions just comment and I'll respond when I see it.

Answer:

If f(x)=g(x), the solution is x=-2

Step-by-step explanation:

We are given:

f(x)=3x+3\\g(x)= (-1/2)x-4

We need to find the solution if f(x)=g(x)

Now solving for f(x)=g(x)

f(x)=g(x)\\3x+3=(-\frac{1}{2}x)-4\\3x+3=-\frac{1}{2}x-4\\3x+\frac{1}{2}x=-4-3\\\frac{3x*2+x}{2}=-7\\\frac{6x+x}{2}=-7\\\frac{7x}{2}=-7\\x=-7*\frac{2}{7}\\x=-2

If f(x)=g(x), the solution is x=-2

When x = -2, we use the second part of the function, so g(-2)=0.

Similarly, g(4) = -4.

Simplify the following completely
Akimi4 [234]

Answer:

A= 360 and B=2 .

Step-by-step explanation:

because the deniminator (bottom) is 4 you have to simplify it down to 2, because that's the lowest you can go. 720/2 is 360 (2 is the lowest that it can go) and 4/2 is 2

Question 1:

For this case we must rewrite the following equation:

-3x + y = 5

If we add 3x to both sides of the equation we have:

y = 5 + 3x

Thus, we have that an equivalent expression is option C.

Answer:

Option C

y = 5 + 3x

Question 2:

For this case we must solve the following equation:

-5x + 5 = -40

Subtracting 5 from both sides of the equation we have:

-5x = -40-5\\-5x = -45

Dividing between -5 on both sides of the equation we have:

x = \frac {-45} {- 5}\\x = 9

Answer:

Option B
