Stan bought a monster truck for $2000 down payment of $450 a month for 5 years. Whats the total cost of the monster truck?
lorasvet [3.4K]

Answer:

$29,000

Step-by-step explanation:

2000 + ([12months x 5years] x 450)

12 times 5 equals 60, therefor Stan will have to pay $450 every month for 60 months.

450 x 60 = $27,000

Then simply add the bought price to the total cost of the down payment.

$27,000 + $2000 = $29,000

A sheet of metal that is 30cm wide and 600cm long is to used to make a rectangular eavestrough by bending the shett an equal amo
tensa zangetsu [6.8K]

Answer:

The sheet should be turned up 7.5cm on each side to obtain maximum volume.

Step-by-step explanation:

If we make a rectangular eavesdrop, by bending the sheet along dotted line, then.

Height of eaves trough = x cm

Length of eaves trough = 600 cm

Width of eaves trough =  (30 - 2x) cm

We know that Volume is given by:

V = Length · Width · Height

V = (x)(30 - 2x)(600)

V = -1200x² + 18000x

To maximize the volume, we take the derivative and put it equal to zero.

\frac{dV}{dx} =\frac{d}{dx}( -1200x^2 +18000x)=0\\\frac{d}{dx}( -1200x^2 +18000x) = 0\\-(2)1200x+18000=0\\-2400x+18000=0\\x=\frac{18000}{2400}\\ x=7.5cm
