To solve this inequality you need to add 2 to both sides.
Which means the answer is add, but I will solve it in this explanation too.

15 in.
22/35 in.
15 3/7 in.
15 5/7 in.
Answers
Answer:
step 1. The circumference (c) of a circle is equal to the diameter of a circle x pi. c = d(pi) = 5pi
step 2. c = 5pi = 5(22/7) = 110/7 = 15 5/7.

Step-by-step explanation:
a) Let P(t) be written as
P(t) = a cos[b(t - d)] + c
The minimum Pmin and the maximum Pmax of P(t) are given.
Pmin = 4
Pmax = 20
c = (Pmax + Pmin) / 2 = (20 + 4) / 2 = 12
|a| = (Pmax - Pmin) / 2 = (20 - 4) / 2 = 8
We now need to find the number of days t after January 1st at which P(t) is maximum by counting the days of the months from January to May and adding 21 days in June.
t = 31 + 28 + 31 + 30 + 31 + 21 = 172
We now use the period to find b (b > 0) as follows
period = 365 = 2π / b
hence b = 2π / 365
A cosine function without shift has a maximum at t = 0. P(t) has a maximum at t = 172. We can model P(t) by a cos(x) function shifted by 172 to the right as follows:
P(t) = 8 cos[(2π / 365)(t - 172)] + 12
check that P(t) is maximum at t = 172: P(172) = 8 cos[(2π / 365)(172 - 172)] + 12 = 8 cos[(0)] + 12 = 20
b) The graph of P(t) is shown below.

Which is greater, 0.28 or 0.205? Explain how you know.
Answers
Answer:
Step-by-step explanation:
0.28 is roughly the same as 0.280, which has 3 significant digits (same as 0.205 has 3 significant digits). It's easier when we compare numbers having the same number of decimal places.
Comparing 0.280 to 0.205, we see that the hundredths place of 0.280 (which is 8) is greater than the hundredths place of 0.205 (which is 0). Thus 0.28 is greateer than 0.205.

5.7 is increased to 7.8
What is the percentage of increase?
Answers
Answer:
7.8%
Step-by-step explanation:
Answer:
The percentage of increase is 37%
Step-by-step explanation:
The way to find the percentage of increase is to divide The difference between the two numbers by the number before the increase
7.8 - 5.7 = 2.1
The difference between 7.8 and 5.7 is 2.1
So now we divided 2.1 by the number before the increase, in this case, 5.7
2.1 ÷ 5.7 = 0.3684
0.3684 rounded to the nearest hundredth is 0.37
Thus the percentage of increase is 37%

Answers
Answer:
I believe the answer is C.
Step-by-step explanation:
Answer:
B.Step-by-step explanation:
It would be B. since both triangles are right triangles. They also are on the same line. So neither of them are at a different angle.
Now to verify that this is correct, we need to eliminate some of the other answers.
Let's start with A.. Congruent means that they are the same shape and size and can be mirrored/backwards. These triangles are the same shape and mirrored but it IS NOT the same size. This means we can eliminate answer A..
Now answer C.. As originally stated, the triangles are similar because they are both right triangles, but they have the same slope since they are on the same line. The line is not changing so the slope will not change either.
And finally answer D.. Answer D. has been proven wrong from the answers B. and C., so we can eliminate it.
This means all the answers are eliminated but B.
