Answer:
The center is (5, -2) and the radius is 9/2
Step-by-step explanation:
The equation of a circle can be written in the form
(x-h) ^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x − 5)^2 + ( y + 2 )^2 = 81/4
(x − 5)^2 + ( y - -2 )^2 = (9/2)^2
The center is (5, -2) and the radius is 9/2
You have 2 dekagrams of brand x fertilizer and 9 grams of brand y fertilizer how much fertilizer do you have in grams
M=f+240
m+f=25000, using m from above in this equation gives you:
f+240+f=25000 combine like terms on left side
2f+240=25000 subtract 240 from both sides
2f=24760 divide both sides by 2
f=12380, and since m=f+240
m=12620
So there are 12620 males and 12380 females in the city.
If my math is right it should be b
