Answer:

Step-by-step explanation:

The question is not well structuredand lack some information.

Restructured:

Another submarines dissent can be modeled as Y= -250 X, where Y is the vertical position and X is the. access time in hours. How long will it take the submarine to make dissent of -200ft?.

To get the time taken to dissent -200ft., we will have to substitute

Y = -200ft into the given expression as shown;

Y = -250X

-200 =-250X

Rearrange

-250X = -200

-25X = -20

Divide both sides by -25

-25X/-25 = -20/-25

X = 20/25

X = 4/5 hrs

Convert to minutes

X = 4/5 × 60

X = 4×12

X = 48minutes

Hence submarine will take 48minutes to dissent -200ft

The equation for the cost in dollars of producing automobile tires is c = 0.000015x2 - 0.03x + 35, where x is the number of tire
statuscvo [17]
The cost function is
c = 0.000015x² - 0.03x + 35
where x = number of tires.

To find the value of x that minimizes cost, the derivative of c with respect to x should be zero. Therefore
0.000015*2x - 0.03 = 0
0.00003x = 0.03
x = 1000

Note:
The second derivative of c with respect to x is positive (= 0.00003), so the value for x will yield the minimum value.

The minimum cost is
Cmin = 0.000015*1000² - 0.03*1000 + 35
          = 20

Answer:
Number of tires = 1000
Minimum cost = 20

The perimeter of a rectangle is less than or equal to 50 inches. The length of the rectangle is 10 inches. What inequality repre
kupik [55]

Answer:

w ≤ 15

Step-by-step explanation:

A rectangle is shape with 4 sides where 2 pairs of sides are equal and form 4 perpendicular angles. 1 pair of sides is the width and is distance w. 1 pair of sides is the length and is 10 inches. The total distance around the shape is the perimeter. We know the perimeter is 50 inches or less. Add each side together and let it be less than or equal to 50. Then solve for w.

P ≥ l + l + w + w

50 ≥ 10 + 10 + w + w

50 ≥ 20 + 2w

30 ≥ 2w

15 ≥ w
