To determine how many acres would minimize cost, we need to differentiate the expression given and set it to zero and obtain the value of x. We do as follows:
C(x) = 0.2x^2 - 12x +240
C'(x) = 0.4x - 12
0 = 0.4x - 12
x = 30 acres <---------amount of flowers needed to minimize cost
Answer:
School X: 8 points School Y: 2.6̅ or 6 repeating.
Step-by-step explanation:
When you know that School X has <em>8 points</em>, and School Y has <em>3 times less</em>, you have to divide 8 by 3. When you do that, you get 2.6̅, or 2.6 repeating, which means that you have 2 that goes into 3 goes into 8 3 times, because 3 x 3 would be 9, which is bigger than 8. Anyway, when you divide again because you have to add a decimal point after the number to keep dividing, <em>you keep getting 6</em>. it's never going to change, because thats what 6̅ is. 6 REPEATING.
I hope this helps! ;)
Answer:
<h2>3(2+4)÷(10-1) = 2</h2><h2 />
Step-by-step explanation:
3×(2+4)÷(10-1) = 3×(6)÷(9) = 18÷9 = 2
Translated down is changing y coordinate
(-2,4)
4-6 = -2
Coordinates of A’ is (-2,-2)
(-4,-7)
reflect over the y-axis
(x,y) -> (-x,y)
(-4,-7) -> (4,-7)
Coordinates of B’ is (4,-7)
Hope this helps!
11.99 x 0.1 = 1.20
11.99 - 1.20 = 10.79
10.79 x 0.07 = 0.76
10.79 + 0.76 = 11.55
Your final answer is $11.55
