Point B is the midpoint of line segment AC
so 2 * (AB) = AC
2(3x) = 5x + 21
6x = 5x + 21
x = 21

The graphs of can be obtained from the graph of the cosine function using the reciprocal identity, so:
But in this problem, the graph stands for the function:
Because the period is now 4π as indicated and for in the figure and this can be proven as follows:
Also, as indicated in the figure and this can be proven as:
Answer:
25
Step-by-step explanation:
20% of 25 is 5
We are given that the temperature is less than (<) -3 degrees Fahrenheit.
Since the temperature is represented by the variable "t", then t is less than -3.
So, the inequality which best describes the situation is:
t < -3
Checking the choices, we will find that the correct choice is:
<span>C: t < -3</span>
