Answer:
Step-by-step explanation:
The shaded region is 2/9 of whole circle.
Calculate the area of a circle:
- radius
Substitute 
Calculate the area of the shaded regions:
Answer:50
Step-by-step explanation:Since there are six friends and there are 500 oranges that would be 500 divided by 6 which equals 50
Answer: If the dimension of V is n, then V has n elements.
Now, dim(U) + dim(W) = n, this means that the addition of the dimensions of U and W also has n elements.
and because U and W are subspaces of V, you know that every element on U and W is also an element of V.
If U ∩ W = ∅, means that there are no elements in common between U and W.
Because there are no elements in common, then Dim(U) + Dim(W) = dim(U ∪ W) = n
So U ∪ W has the same number of elements as V, and every element of W and U is also an element of V
this means that U ∪ W = V.
I’ll give you the awnser from them all, but the show your work from just one. Hopefully you can figure it out. If not, reply with specific things you don’t understand and Ill try to talk it out with you. I struggled alot with this stuff when I was in your age too.
5) The answer is x = 3/4 or x= 0.75
12) x = 4
15) x = 2
Reasoning:
All m
The annual multiplier of the population is 1 +2.7% = 1.027. So, after x years, the population is multiplied by 1.027^x. You want to find the value of x that makes this multiplier be 2.
2 = 1.027^x
log(2) = x*log(1.027)
Then, at a growth rate of 2.7%, the doubling time of the population is
x = log(2)/log(1.027) ≈ 26.02 . . . . . . the number of years after 1987
The population of Country A is expected to be double its 1987 value in the year 2013.
