We are given with the equation
y = e^-9x with the restriction of x <span>≥ 0
If rotated about the x-axis the area of the resulting surface is
A = </span>π ∫ y² dx
Substituing
A = π ∫ (e^-9x)² dx
A = π ∫ e^-18x dx
The limits are from 0 to positive infinity.
I think the answer is y=6x
The total cost for the production of x bags of the chips is equal to the sum of the fixed cost, $1400, and the variable cost which is dependent on the number of bags produced. The final expression for the total cost,
total cost = 1400 + 0.10x
Answer:
-145
Step-by-step explanation:
-5-15-25-x=100
First, get all the numbers(including 100) on one side and x on the other side(make sure x is POSITIVE, not negative)
-5-15-25-100 = x
Two negatives = addition
-5 - 15 = -20
-25 - 100 = -125
Now add, 20 and 125, and keep the negative
-125 - 20 = -145
