Answer:
1 hr at the speed of 50 mph
Step-by-step explanation:
If you went 50 mph it would be 1 hour. 100mph = 30min.
This is x^3+x^2+1=-x in math terms, where x is the number. So x^3+x^2+x+1=0. We can write this: x^2(x+1)+(x+1)=(x^2+1)(x+1)=0. The only real solution is x+1=0, so x=-1.
Hopefully that makes sense
Answer:
edit: I could be off
If you mean y=1x+2 then at x=0 y=2, if x=1 y=3, x=2 y=4, x=3 y=5
Step-by-step explanation:
whatever x is equalled to, y is x plus 2
Answer:
x = 100 units
Step-by-step explanation:
C = 2.5x^2 + 75x + 25000
To find average cost per unit, divide C by x:
C/x or Average cost (AC) per unit = = 2.5x + 75 + 25000/x ⇔ 2.5x + 75 + 25000x^-1 (equation 1)
To find cost minimising, we use differentiation (differentiate equation 1 in respect to x and set it equal to 0):
d(AC)/dx = 0
d(AC)/dx ⇔ 2.5 - 25000x^-2 = 0
2.5 = 25000x^-2
2.5 =
2.5x^2 = 25000
x^2 = 10000
x =
x = 100 units
This is the answer my friend
