Answer:

C

Step-by-step explanation:

A doesn't make sense, because there are probably many people younger than 50.

Not B because that would be hard since there are probably not many people coming to the gallery by themselves.

Lastly,

Not D because that isn't very fair because since the women probably have different views than the men.

B makes the most sense because it does not rule anyone out and it lets everyone have an equal chance of being surveyed.

A circle has a center at A (4,5), Determine the radius of the circle given two end points of the circle are B (9,5) and C (-1,5)
Anna71 [15]

ANSWER :

The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r". This form of the equation is helpful, since you can easily find the center and the radius.

What is the surface area of 5, 8, and 3
Rashid [163]

Answer:

158

Step-by-step explanation:

5*8=40

8*3=24

3*5=15

Each of these measurements gets added twice, becasue there are 6 faces on a rectangular prism.

40 + 40 + 24 + 24 + 15 + 15 = 158

Select the graph of y=cot x.
Kisachek [45]

Because of the vertical asymptote and the change in concavity, we conclude that the correct option is B.

<h3>Which is the graph of cotangent of x?</h3>

Remember that cot(x) = 1/tan(x).

Then we can rewrite:

cot(x) = cos(x)/sin(x).

We know that for x = 0, we have:

cot(0) = cos(0)/sin(0) = 1/0

Then we have a vertical asymptote that tends to ± infinity.

The only graph that meets this condition is the second and the third one, and by the curvature (we need to have a change of concavity/convexity) in the tangent function.

From that, we conclude that the correct option is B.
