Answer:
The farmer should plant 14 additional trees, for maximum yield.
Step-by-step explanation:
Given
So, we have:
Required
The additional trees to be planted for maximum yield
The function is:
Open bracket
Rewrite as:
Differentiate
Equate to 0 and solve for x to get the maximum of x
Divide by -4
The farmer should plant 14 additional trees, for maximum yield.
Answer:
30
Step-by-step explanation:
Work backwards:
- 6 is 3/5 of a number, and that number is 10
- 10 is 1/3 of a number, and that number is 30
Check your work:
- 2/3 of 30=20 toy to Sarah
- 30-20=10 toys left
- 2/5 of 10=4 toys to Ryan
- 10-4=6 toys left
<h2><u>Answer</u>:-</h2>
1) -11 + <u>2</u><u>6</u> = 15
2) <u>2</u> - (-3) = 5
3) <u>1</u><u>1</u> + (-4) = 7
4) <u>5</u> + -8 = -3
5) -2 + <u>3</u> = 1
6) <u>8</u> - 12 = -4
Answer:
8x - 7y = 56
Step-by-step explanation:
in order for lines to be parallel they need to have the same slope, the easiest way to determine if they have the same slope is to change the equations into y = mx + b form by solving for y and seeing where m=8/7
so 8x - 7y = 56
-7y = 56 - 8x
y = 56/-7 -8x/-7
y = -8 + 8/7 x
When a number is followed by an exclamation point (!) it means that number gets multiplied by all the numbers below it.
So 7! = 7*6*5*4*3*2*1 = 5040
4! = 4*3*2*1 = 24
6! = 6*5*4*3*2*1 = 720
Now the equation is:
5040 * 24 -720
5040 *24 = 120960
120960 - 720 = 120240
The answer is A.
