Answer:
A. 4(x^2 + 2x + 1) + 15 - 4 = 0
Step-by-step explanation:
Because we have to make the expression in the brackets a perfect square by adding 1 and then, as we have introduce + 1 * 4 = + 4 into the equation, we must later subtract the 4.
Answer:
Step-by-step explanation:
P1 = (2000, 1000) in the form (x1,y1)
P2 = (2012, 3400) in the form (x2,y2)
m = (y2-y1 / x2-x1)
m = ( 3400-1000 ) / (2012 - 2000)
m = 2400 / 12
m = 200
y = 200x + 800
Answer:

Answer:
For the 1st question (4) For the 2nd question (1)
Step-by-step explanation:
(4) because 15000x+10000y needs to be less than or equal to 20000 or else they're going over the budget but x+y needs to be less than or equal to 15 as they can't make more than that.
(1) Divide both sides by pi and h then square root both sides.
