Answer:
D
Step-by-step explanation:
We need the formula for arc length (in radians) to solve this problem. The formula is:

Where
s is the arc length
r is the radius of the circle
is the intercepted angle
In this diagram, we can see that
is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20
Also, if we look, we see that the radius is 5 cm, so r = 5
Now, we substitute into formula and find
:

This is given in radians, so
is 4 radians
D is the correct answer choice.
Credit Cards: You don't have to worry about how much cash you have at hand. You can get money when you need it.
Money: You won't overspend. You won't have to worry about fees.
The prisoners could do a pattern that could signal who has already been in the room. So for example, one light off, both lights off, one light on, both lights off. But with left and right lights to make the sequence last as long as possible. Then after that sequence to have the last one be the signal that everyone has been in there. I dunno this is tricky lol
Answer:
the price of good x in 1999 dollars is 370.89 dollars
Step-by-step explanation:
Given that good x sold for $40 in 1945. the Cpi in 1945 was 18.0 and the cpi in 1999 was 166.6.
We have cpi and sale price have direct variation
In other words S = kC where C = CPi and S = sales price
In 1945, 40 = 18k or K = 20/9
Using this we can say
Sales price in 1999 would be k (166.6)
=
the price of good x in 1999 dollars is 370.89 dollars
Hello from MrBillDoesMath!
Answer:
Binomial with a degree of 6 (the second Choice)
Discussion:
(a^3b+9a^2b^2-4ab^5) - (a^3b-3a^2b^2+ab^5) =
(-4ab^5- ab^5) + ( a^3b-a^3b) + ( 9a^2b^2 + 3a^2b^2) =
(-4ab^5- ab^5) + 0 + ( 9a^2b^2 + 3a^2b^2) =
12 a^2 b^2 - 5 a b^5
This is a binomial with degree 6 (degree of last term = 1 + 5 = 6).
Thank you,
MrB
