Find the area under the curve y = 13/x3 from x = 1 to x = t. Evaluate the area under the curve for t = 10, t = 100, and t = 1000
zvonat [6]

Answer:

t = 10

A = 32496.75

t = 100

A = 324999996.8

t = 1000

A=3.25\times 10^{12}

Step-by-step explanation:

The area under the curve is calculated by using the following definite integral:

A = \int\limits^t_ {1} \,{13\cdot x^{3}}  dx

A = 13 \int\limits^t_1 {x^{3}} \, dx

A = \frac{13}{4}\cdot (t^{4}-1)

Evaluated areas are presented below:

t = 10

A = 32496.75

t = 100

A = 324999996.8

t = 1000

A=3.25\times 10^{12}

Which of the following would be the most appropriate unit to measure the volume of oil in a large tank?
Elenna [48]

Answer:

Option C

Step-by-step explanation:

Option D's unit is not used in volume measurement. A "ton" is 2,000 lbs. Pounds are not used to measure volume.

Since we are looking at the volume of a "large tank", then a quart and a pint would be too small, and therefore, not the most appropriate units to measure the volume of the tank with.

A "kiloliter" is equivalent to 1,000 liters. Note that the prefix "Kilo-" means 1,000. A kiloliter would be appropriate for measuring the volume of a large object, in this case a oil tank. It is the most appropriate out of the options given.

Option C should be the correct answer.
