X = - 4; y = 3; z = 2;
2 x² - 2 z^4 + y² - x² + z^4 =
= 2 * (-4)² - 2 * 2^4 + 3² - ( -4)² + 2^4 =
= 2 * 16 - 2 * 16 + 9 - 16 + 16 =
= 32 - 32 + 9 - 16 + 16 = 9
Answer:
The percentage of people is 60%
Step-by-step explanation:
The reasoning this is the answer is because you to find the percentage you take the amount which does the thing or the part of the whole which is included in the slection ad you divide it by the total and multiply that by 100 so (2100/3500)*100 and that gives you 60%
6x=4.50
x = price per container
x=4.50 / 6
x= .75 per container
.75 * 8containeers = $6
I'm not sure I think the answer 7
General form for circle is
(x - a)^2 + (y - b)^2 = r^2
so if center is at (3,-2) we can plug in a and b:-
(x-3)^2 + (y+2)^2 = r^2
Now plug in x = 7 and y =1 (from the point R)
4^2 + 3^2 = r^2
r^2 = 25 making r = 5
so its diameter = 2*5 = 10
