Answer:
Step-by-step explanation:
36/6 · 2 + 1
6 ·2 + 1
12 + 1 = 13
answer is 13
Answer:
y=32
Step-by-step explanation:
cross multiply
36/4 *144/y
144*8/36
=1152/36
y=32
A cosine is just a sine shifted to the left by π/2. A cosine of 4x is shifted to the left by only π/8 because of the factor 4. Sketch them.
The region we're looking for is this sausage-shaped part between the cos and the sin.
The x intercepts are at π/8 for the cosine and π/4 for the sine. The midpoint between them is at (π/8 + π/4)/2 = 3/16π.
The region is point symmetric around the x axis, so the y coordinate of the centroid is 0.
So the centroid is at (3/16π, 0)
Answer:
d. f opens upward with a y-intercept at (0, 2); h opens downward with a y-intercept at (0, -2)
The first step to getting this in vertex form would be to put this in proper standard form. This is so that you can split the middle term which is a step of completing the square.
