Answer:
C the soyabean on the various plots of land.
Step-by-step explanation:
The experiment is to measure the yield of soyabean plant across the various 12 portions of land labelled A's ,B's and C's .
withdraw means subtract, deposit means add
152 withdraws 20 deposits 84
152 -20 + 84
152 - 20 + 84 = 132 + 84 = 216
Now she has $216 in the bank

2 rectangle shaped
1) Length = 160 mi ; Width = 40 mi
2) Length = 440 mi - 160 mi ; Width = 240 mi - 70 mi
1 triangle shape
1) base = 70 mi ; height = 440 mi - 160 mi
Area Rectangle 1 = 160 mi * 40 mi = 6,400 mi²
Area Rectangle 2 = 280 mi * 170 mi = 47,600 mi²
Area Triangle 1 = ((440 mi - 160 mi) * 70mi)/2 = (280mi * 70mi)/2 = 9,800 mi²
Total Area = 6,400 mi² + 47,600 mi² + 9,800 mi² = 63,800 mi²
Rewrite it into vertex form with completing the square:
f(x) = x^2 - x + 2 = (x^2 - x) + 2 = (x^2 - x + 1/4) + 2 + 1/4 = (x - 1/2)^2 + 9/4;
So the vertex is (1/2, 9/4).
Answer:
X > (whatever the symbol is) 0
Step-by-step explanation:
kinda like algebra:
x + 2 > 2
X > 0
