anastassius [24]

Answer:

$32

Step-by-step explanation:

The lady charges $2.00 for gas which means over a 4 hour period we would do

4 x 2 = 8

She makes a total of 8 dollars

She also gains $3.00 per half hour of work

This means we would do 3 x 8

24

We add these values to get $32

In the triangle shown, B=60 and AC=9√3 how long is AB answer exactly, use a radical if needed
zavuch27 [327]

Length of AB is 18

Step-by-step explanation:

  • Step 1: Find length of AB when AC = 9√3 and ∠B = 60°. Use trigonometric ratio sine.

sin 60 = opposite side/hypotenuse = 9√3/x

x = 9√3/sin 60

   = 9√3/√3/2 = 9√3 × 2/√3 (∵ a ÷ b = a×1/b)

   = 18

A rectangular storage container with an open top is to have a volume of 10 m3. the length of this base is twice the width. mater
BartSMP [9]
Refer to the diagram shown below.

The volume of the container is 10 m³, therefore
x*2x*h = 10
2x²h = 10
h = 5/x²        (1)

The base area is 2x² m².
The cost is $10 per m², therefore the cost of the base is
(2x²)*($10) = 20x²

The area of the sides is
2hx + 2(2xh) = 6hx = 6x*(5/x²) = 30/x m²
The cost is $6 per m², therefore the cost of the sides is
(30/x)*($6) = 180/x

The total cost is
C = 20x² + 180/x

The minimum cost is determined by C' = 0.
That is,
40x - 180/x² = 0
x³ = 180/40 = 4.5
x = 1.651
The second derivative of C is
C'' = 40 + 360/x³
C''(1.651) = 120 >0, so x = 1.651 m yields the minimum cost.

The total cost is
C = 20(1.651)² + 180/1.651 = $163.54

Answer: $163.54
