Answer:
8xy
Step-by-step explanation:

Answer:
163 degrees and 17 degrees
Step-by-step explanation:
x+y = 180
x-y = 146 then x = 146+y
substitute for x
146+y+y = 180
2y = 34
y = 17
x = 17+146 = 163
GG easy
I=(r)(t)(P)P=principalr=rate in decimalt=timei=interest
so just plug in what you know to solve for what you don't know
first oneI=(0.05)(3)(100)
I=15
2nd one20=(0.04)(t)(500)20=20tdivide by 20 both sides1=tt=1
3rd one35=(0.10)(7)(P)35=0.70Pdivide both sides by 3550=PP=50
4th one6=(r)(2)(200)
6=400rdivide both sides by 4000.015=rconvert to percent1.5%=r
What you should do for this casp is to use the given expression and clear the value of x.
We have then:
y = 1.245x - 3.684
Clearing x:
1.245x = (y + 3.684)
x = (y + 3,684) / (1,245)
Substituting the value of y:
x = ((40) +3,684) / (1,245) = 35.09
x = 35

Answer:
a. C(1,000) = 420,491.11
b. c(1,000) = 420.49
c. dC/dx(1,000) = 429.72
d. x = 900
e. c(900) = 420
Step-by-step explanation:
We have a cost function for x units written as:

a. The total cost for x=1000 units is:

b. The average cost c(x) can be calculated dividing the total cost by the amount of units:

c. The marginal cost can be calculated as the first derivative of the cost function:

d. This value for x, that minimizes the average cost, happens when the first derivative of the average cost is equal to 0.

e. The minimum average cost is:
