The radius of a cylindrical gift box is (3x + 2) inches. The height of the gift box is twice the radius. What is the surface area of the cylinder?

Answers

Answer 1

The radius of a cylindrical gift box is ​(3x+2​) inches. The height of the gift box is twice the radius. The surface area of the​ cylinder is 54πx² + 84πx + 32π square inches.

What is the surface area of a cylinder?

The surface area of a cylinder is given as:

2πr(r + h)

The radius of a cylindrical gift box is ​(3x+2​) inches. The height of the gift box is twice the radius.

We need to find the surface area of the​ cylinder.

The radius of a cylindrical gift box is ​(3x+2​) inches.

The height of the gift box is twice the radius = 2(3x + 2) inches

= 6x + 4 inches

The surface area of the cylinder is:

= 2 × π × (3x + 2)( 3x + 2 + 6x + 4) square inches

= 2 × π × (3x + 2)(9x + 8) square inches

= 6πx + 4π( 9x + 8) square inches

= 6πx (9x + 8) + 4π( 9x + 8) square inches

= 54πx² + 48πx + 36πx + 32π square inches

= 54πx² + 84πx + 32π square inches

Hence, The surface area of the​ cylinder is 54πx² + 84πx + 32π square inches.

Answers

Answer:

y = 3x + 3

Step-by-step explanation:

when you check, only that equation delivers the correct x and y pairs.

x = 0, => y = 3×0 + 3 = 3

x = 1, y = 3×1 + 3 = 3+3 = 6

x = 2, y = 3×2 + 3 = 6 + 3 = 9

x = 3, y = 3×3 + 3 = 9 + 3 = 12

Find the surface areas of the rectangular prism and the triangular prisms separately.
Triangular: S = (1/2)lP+B, where l is slant height, P perimeter, and B base area.
14(4)= 56 perimeter of base
13 slant height
B = 14x14 = 196
put together:
S = (1/2)(13 x 56) + 196
S = 560 in^2

Now the rectangular prism
S = 2lw + 2lh + 2wh, where l is length, h height, w width. (delete the first 2lw since they share one side/they're combined shapes.
S = 2(14x8.9) + 2(14x8.9)
S = 498.4 in^2

Add them together: 498.4 + 560 = 1058.4 in^2

Solve the equation 14x + 7y= 28 for x.
O A. x-y-2
OB. x = 28-7y
O C. x = 2-y
O D. x = 4-y

Answers

The equation that represents the solution of x is x = 2 - y/2

How to solve the equation?

The equation is given as:

14x + 7y = 28

Divide through by 7

2x + y = 4

Subtract y from both sides

2x = 4 - y

Divide both sides by 2

x = 2 - y/2

Hence, the equation that represents the solution of x is x = 2 - y/2

Degree Male Female
Associate 245 433
Bachelors 598 858

Answers

P(the recipient is male)= 40.5%

p(the degree is a bachelors) = 52%

p(the recipient is female, given that the degree is advanced)  = 56.2%

p( the degree is not an associates, given that the recipient is male) = 78.4%

What are the probabilities?

Probability determines the chances that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

P(the recipient is male) = total number of males / total number of recipients

1136/2803 = 40.5%

p(the degree is a bachelors) = total number of bachelors degree / total number of degree

= 1456 / 2803 = 52%

p(the recipient is female, given that the degree is advanced) = total number of females with advanced degree / total number of advanced dgree

376 / 669 = 56.2%

p( the degree is not an associates, given that the recipient is male) = number of males that that have degrees other than associates / total number of males

How to calculate the limits?

The expressions are given as:

[tex]3^{2n} + 1[/tex]

[tex]4^{n + 2} - 3[/tex]

The limits of the expressions as they approach infinity are represented as:

[tex]\lim_{n \to \infty} 3^{2n} + 1[/tex] and [tex]\lim_{n \to \infty} 4^{n + 2} - 3[/tex]

Substitute [tex]\infty[/tex] for n in both expressions

[tex]\lim_{n \to \infty} 3^{2 * \infty} + 1[/tex] and [tex]\lim_{n \to \infty} 4^{\infty + 2} - 3[/tex]

Solve both expressions independently;

[tex]\lim_{n \to \infty} 3^{2n} + 1 = 3^{2 * \infty} + 1[/tex]

Evaluate the product

[tex]\lim_{n \to \infty} 3^{2n} + 1 = 3^{\infty} + 1[/tex]

Evaluate the exponent

[tex]\lim_{n \to \infty} 3^{2n} + 1 = \infty + 1[/tex]

Evaluate the sum

[tex]\lim_{n \to \infty} 3^{2n} + 1 = \infty[/tex]

Also, we have:

[tex]\lim_{n \to \infty} 4^{n + 2} - 3 = 4^{\infty + 2} - 3[/tex]

Evaluate the sum

[tex]\lim_{n \to \infty} 4^{n + 2} - 3 = 4^{\infty} - 3[/tex]

Evaluate the exponent

[tex]\lim_{n \to \infty} 4^{n + 2} - 3 =\infty - 3[/tex]

Evaluate the difference

[tex]\lim_{n \to \infty} 4^{n + 2} - 3 =\infty[/tex]

Step-by-step explanation:

Sum of n terms of an A S with first term 1 and common difference 1:-

496 = (n/2)(2(1) + 1(n - 1))

496 = (n/2)(n + 1)

n^2/2 + n/2 = 496   Multiply through by 2:-

n^2 + n = 992

n^2 + n - 992 = 0

(n - 31)(n + 32) = 0
