Answer:
Step-by-step explanation:
The formula of a circumference of a circle:
<em>r</em> - radius
The formula of an area of a circle:
<em>r</em> - radius
We have C = 176cm. Substitute to the formula and calculate the radius <em>r</em>:
Calculate the area:
According to the moderator, I should take 
. You can do it like that. In my opinion, my solution is correct.
Answer is 4.04 by adding both of the time of each then subtracting then from each others time
First, multiply the first equation by 2.
That turns the first equation into:
6x - 2y = 18
That way it can easily be added to the second equation:
6x - 2y = 16
x + 2y = 5
---------------
7x = 21
==========
As you can see, the y disappeared, which was the objective of this operation.
Now the equations can be solved easily:
7x = 21
x = 3
Insert x=3 in the original equation:
3*3 - y = 8
9 - y = 8
9 = 8 + y
y = 1
So the result is:
x = 3
y = 1
AB is not parallel to ED because if it were, it would have little arrows to indicate it. Also the measure of angle A is not 60 degrees it would be 140 degrees since angle B and C are 20.
Answer:
Step-by-step explanation:
<u>Given</u>
- u(x) = x^5 - x^4 + x^2 and v(x) = -x^2
<u>(u/v)(x) = </u>
- (x^5 - x^4 + x^2) /(- x^2) =
- - (x^3 - x^2 + 1) =
- -x^3 + x^2 - 1
Correct option is C
