Answer:
31 trees per acre will maximize the harvest
Step-by-step explanation:
Given
trees/acre
bushels
Required
Number of trees to maximize harvest
From the question, we understand that:
Yield will decrease by 4 i.e. 25 - 4x
For every additional tree planted, i.e. 55 + x
So, the function is:
Open bracket
Rewrite as:
The maximum of a quadratic function is calculated as:
In the above equation:
So:
Recall that the number of trees to be planted is: 55 + x
So, we have:
Approximate
The group of three. they have a greater amount of berries to share and are also less
Answer:
4. 7/100
5. -3 85/99
6. 26/33
7. 2 27/50
Step-by-step explanation:
4.
0.07 = 7/100
5.
We need to change 0.8585... into a fraction.
100x = 85.8585...
(-) x = 0.8585...
-----------------------------
99x = 85
x = 85/99
-3.858585... = -3 85/99
6.
100x = 78.7878...
(-) x = 0.7878...
------------------------------
99x = 78
x = 78/99
x = 26/33
0.787878... = 26/33
7.
2.54 = 2 + 0.54 = 2 + 54/100 = 2 + 27/50 = 2 27/50
Y= -2(x-2)^2-3 you have y equal to parenthesis x minus 2 close parenthesis to the square minus 3
Answer:
256x - 81
Step-by-step explanation:
16x x 16=256x
You cannot add a number with a variable with a number without a variable so the answer is 256x - 81
