Y = cos x begins at (0,1), descends to (pi/2,0), descends to (pi,-1), ascends to (3pi/2,0), and then ascends to (2pi,1). This covers only one full period.
The graph of y = 2cost x is the same, except that the amplitudes (y-values) are 2x as great as before:
(0,2), (pi/2, 0), and so on.
Answer:
Step 3, because the values for x for which y^1 < y^2 also include values between 3 and 5.

Answer:
<em>There were 204 ladies and 136 gentlemen in the conference</em>
Step-by-step explanation:
Let's set the variables:
L = number of ladies in the conference
G = number of gentlemen in the conference
We know 340 people participated in the conference, thus:
L + G = 340 [1]
We are also given the ratio of ladies and gentleman as 3:2, thus:
L/G = 3/2
Cross-multiplying:
2L = 3G [2]
From [1]:
L = 340 - G
Substituting in [2]:
2(340 - G) = 3G
Operating:
680 - 2G = 3G
5G = 680
G = 680/5 = 136
G = 136
L = 340 - 136 = 204
L = 204
There were 204 ladies and 136 gentlemen in the conference
4x=5 Answer: so 5/4
Step-by-step explanation: 8x-4 = 4x + 1
add like terms so 4x=5 then divide
