Answer:
I think it’s 1
Step-by-step explanation:
Because it’s a right triangle and it’s equal to 90° So
and 2,3,4 is less than 90 so
P=20x-0.01x^2-240
P=20(300)-0.01(300)^2-240
P=6000-0.01(90000)-240
P=6000-900-240
P=4860
Remember PEMDAS
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
EXPLANATION: first Is Parentheses, which would be 300, multiply that by 20, that would be 6000.
Next is Exponents, which would be the (^2) so you would Multiply the 300 by itself 2 times. which is 90000
Next is Multiplication, Multiply 0.01 by 90000, which would be 900.
There is nothing to divide or add so skip that.
Next is subtraction, subtract 6000-900-240 and the answer would be 4860.
so Faith's prediction profit for this season would be 4860 when her orchard produces 300 bushels of apples.
I hope that helped! Good Luck!

1 2/
5
Step-by-step explanation:
We use quadratic formula for that one
remember that √-1=i
so
for
ax^2+bx+c=0
![x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-b%2B%2F-%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D)
so
given
5x^2-6x+2=0
a=5
b=-6
c=2
![x=\frac{-(-6)+/-\sqrt{(-6)^2-4(5)(2)}}{2(5)}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-%28-6%29%2B%2F-%5Csqrt%7B%28-6%29%5E2-4%285%29%282%29%7D%7D%7B2%285%29%7D)
![x=\frac{6+/-\sqrt{36-40}}{10}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B6%2B%2F-%5Csqrt%7B36-40%7D%7D%7B10%7D)
![x=\frac{6+/-\sqrt{-4}}{10}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B6%2B%2F-%5Csqrt%7B-4%7D%7D%7B10%7D)
![x=\frac{6+/-2i}{10}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B6%2B%2F-2i%7D%7B10%7D)
