Answer:
Step-by-step explanation:
A is correct. csc x = 1/ sin x
B is correct. y = sin x is a continuous funtion, for all real numbers, x
C is correct. The function y = sin x is a periodic function, and the cycle repeats every 2 radians (or 360°).
D is incorrect. It doesn't actually say anything false, but it does not accurately describe the behavior of the sine function. Look at the graphic I have attached. If you start at the origin, you see y = 0, then increases to 1 when x = π/2, <u>then decreases back to zero when x = π,</u> then decreases even more to -1 when x = 3π/2, then increases back up to zero when x = 2π.
Answer D leaves out the underlined part.

We know that
<span>the isosceles triangle has two equal sides
</span>
<span>let's analyze two cases
</span>
first case
perimeter=22 cm
<span>let's suppose that the known side of 6 cm is one of the two equal sides
</span>perimeter=6+6+x
22=6+6+x-----> x=22-12----> x=10 cm
answer first case
<span>the possible lengths of the other two sides are
</span>6 cm
10 cm
second case
let's suppose that the known side of 6 cm is the side that is not equal
perimeter=22 cm
perimeter=6+x+x
22=6+x+x----> 2x=22-6----> 2x=16-----> x=8 cm
answer second case
the possible lengths of the other two sides are
8 cm
8 cm
I would say she should spin the wheel because, if she rolled the dice it would take a long time to get 2 5's on both dice at one time.

<span>The slope of a line tells us how something changes over time. If we find the slope we can find the </span>rate of change<span> over that period </span>of change means.
A great website that could help you understand this is http://www.algebra-class.com/rate-of-change.html. But I can help you with this.
