Answer:

The range is from -6 to 4 (inclusive).

The range is the set of y values for which the relation exists.

Looking for bottom to top the curve exists everywhere from y=-6 (lowest y) to y=4 (highest y).

The range is [-6,4] in interval notation.

The range is -6 \le y \le 4 in inequality notation.

If x=1+√2, evaluate x³+1/x³.
aleksandr82 [10.1K]

Answer:

10√2

Step-by-step explanation:

If x=1+√2, evaluate x³+1/x³

--------

  • x³+1/x³= (x+1/x)(x²-x*1/x+1/x²)=(x+1/x)(x²+1/x²+2-3)= (x+1/x)((x+1/x)²-3)
  • x+1/x= 1+√2 + 1/(1+√2)= 1+√2+(1-√2)/(1-√2)(1+√2)= 1+√2 - (1-√2)= 2√2
  • x³+1/x³= 2√2((2√2)²-3)= 2√2(8-3)= 10√2

Using the feasible region below, determine which x and y values will maximize the profit, P, in the equation P = 40x + 55y * 1 p
Kay [80]

Answer:

B (300, 400)

Step-by-step explanation:

The profit maximization will be when the sum of the products will be greater. The maximum profit will be when x is 300 and y is 400. If we put in the equation :

P = 40x + 55 y

A - When x =  0 , y = 500

P = [40 * 0] + [55 * 500]

P = 27500

B -

When x =  300 , y = 400

P = [40 * 300] + [55 * 400]

P = 34000

C -

When x =  380 , y = 200

P = [40 * 380] + [55 * 200]

P = 26200

D -

When x =  400 , y = 0

P = [40 * 400] + [55 * 400]

P = 16000
