6.75% rounded to the nearest cent 6.80%

Sales tax is $2.01

$29.55 + $2.01 = $31.56

Find the volume of the solid by rotating the region bounded by y=x^3, y=8, and x=0 about the y axis.

dimulka [17.4K]

Answer:

Solution : Volume = 96/5π

Step-by-step explanation:

If we slice at an arbitrary height y, we get a circular disk with radius x, where x = y^(1/3). So the area of a cross section through y should be:

A(y) = πx^2 = π(y^(1/3))^2 = πy^(2/3)

And now since the solid lies between y = 0, and y = 8, it's volume should be:

V = ∫⁸₀ A(y)dy (in other words ∫ A(y)dy on the interval [0 to 8])

=> π ∫⁸₀ y^(2/3)dy

=> π[3/5 * y^(5/3)]⁸₀

=> 3/5π(³√8)⁵

=> 3/5π2^5

=> 96/5π ✓

Ronald is making hats and scarves for charity. He has enough yarn to make 5 hats and 8 scarves. Takes him 12 hrs to knit a hat,

kari74 [83]

Constraints are simply the subjects of an objective function.

The inequality that represents the constraint is: $12x + 6y \le 20$

Represent the number of hats with x, and the number of scarves with y.

From the question, we have:

He spends 12 hours to knit a hat
He spends 6 hours to knit a scarf

So, the equation of the total time spent is:

$Time = 12x + 6y$

This time spent is not more than 20 hours.

So, the inequality is

$12x + 6y \le 20$

Hence, the inequality that represents the constraint is: $12x + 6y \le 20$

Which of the following is the sum of all the odd integers between 5 and 102?

STALIN [3.7K]

Answer:

2601

Step-by-step explanation:

The integers between 5 and 102 are

7, 9, 11, 13, 15, 17,19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99, 101

The sum of the odd intergers between 2 and 105 can be calculated as follows

= (N + 1/2)^2

= (101 + 1 /2) ^2

= (102/2)^2

= 51^2

= 2601

Hence the sum of the odd intergers between 5 and 102 is 2601
