Answer:

  276.460 mi²

Step-by-step explanation:

You want the surface area of a cylinder with radius 4 mi and height 7 mi.

The area of a cylinder is given by the formula ...

  A = 2πr(r +h)

  A = 2π(4 mi)(4 mi +7 mi) = 88π mi² ≈ 276.460 mi²

The area of the cylinder is about 276.460 square miles.

The expected value of the winnings in this game is $1.23.

We have,

The expected value of a random variable is the sum of the products of each possible outcome and its probability.

In this case, the random variable is the winnings from the game and the payout probability distribution specifies the probabilities associated with each possible payout.

The expected value of the winnings is found by multiplying each payout by its probability and summing the products.

Expected value = (0)(0.50) + (1)(0.25) + (2)(0.13) + (4)(0.06) + (8)(0.06)

= 0 + 0.25 + 0.26 + 0.24 + 0.48

Step-by-step explanation: finding x

4x-32=2(3x-21) || 4x-32=6x-42 || 10=2x || 5=x

Answer:  From the calculations, the pair of points with a slope of 4 is option c. (0, -3), (1, 1).

Step-by-step explanation:  

To determine the slope between two points, we can use the formula:

slope = (change in y) / (change in x)

Let's calculate the slope for each pair of points:

a. (1, 4), (–1, 4)

The change in y is 4 - 4 = 0

The change in x is -1 - 1 = -2

slope = 0 / -2 = 0

b. (0, 4), (4, 0)

The change in y is 0 - 4 = -4

The change in x is 4 - 0 = 4

slope = -4 / 4 = -1

c. (0, –3), (1, 1)

The change in y is 1 - (-3) = 4

The change in x is 1 - 0 = 1

slope = 4 / 1 = 4

d. (3, 0), (–1, –1)

The change in y is -1 - 0 = -1

The change in x is -1 - 3 = -4

slope = -1 / -4 = 1/4

Answer:

c. (0, –3), (1, 1)

Step-by-step explanation:

To find the slope, we use the slope formula

m = ( y2-y1)/(x2-x1)

a. (1, 4), (–1, 4)

m = (4-4)/(-1-1) = 0/-2 = 0

b. (0, 4), (4, 0)

m = ( 4-0)/(0-4) = 4/-4 = -1

c. (0, –3), (1, 1)

m = ( -3-1)/(0-1) -4/-1 = 4

d. (3, 0), (–1, –1)

m = (0--1)/(3 - -1) =1/4

a) The possible pairs of mutually exclusive outcomes are given below:

b) The Three of the outcomes that are said to be all mutually exclusive are:

c) The probability of having B and D is written as P(B or D) = P(B) + P(D)

Mutually exclusive events cannot happen at the same time, like rolling a kick the bucket and getting a 1 and a 2. In this case, there are four conceivable results: A, B, C, and D, a few of which we commonly select.

For example, If A is the outcome, C or D cannot be. To find mutually exclusive pairs, we check which outcomes cannot occur together. A and B are mutually exclusive because they cannot both be true.

We have,

The three steps that should be taken to calculate the volume of the prism are:

- Use the formula A = b h to find the area of the base, where b is the length of the base and h is the width of the base.

For a rectangular prism, the base is a rectangle, so the formula is:

A = length x width.

- Use the formula V = B h to find the volume of the prism, where B is the area of the base and h is the height of the prism.

For a rectangular prism, the formula.

V = length x width x height.

- Substitute the given values into the formulas and solve for the volume. For the given rectangular prism with a length of 9 and one-half feet, a width of 24 feet, and a height of 6 feet, we can find the volume by using the formula V = B h.

First, we find the area of the base by using the formula:

A = length x width:

A = (9.5 ft) x (24 ft)

= 228 sq ft

Next, we use the formula V = B h to find the volume:

V = (228 sq ft) x (6 ft)

= 1368 cubic feet

Therefore,

The volume of the prism is 1368 cubic feet.

The area of the triangle is 18.6 units²

Given data ,

Let the triangle be represented as ΔABC

Now , the sides of the triangle are

We can use the law of cosines to find the length of the third side of the triangle:

c² = a² + b² - 2ab cos(C)

c² = 5² + 8² - 2(5)(8)cos(79°)

c ≈ 9.05

Now, we can use Heron's formula to find the area of the triangle:

s = (5 + 8 + 9.05)/2 = 11.525

A = √(s(s-a)(s-b)(s-c))

A = √(11.525(11.525-5)(11.525-8)(11.525-9.05))

A ≈ 18.6

The equation of line L2 in the form y = mx + c is y = (2/3)x + 23/3.  the x-intercept of L3 is -14/3. the y-intercept of L3 is -7. The point of intersection between L2 and L3 is (-88/13, 41/13).  The x-intercept of L3 is -14/3.

(a) To find the equation of line L2 perpendicular to line L1, we need to determine the slope of L1 and then use the negative reciprocal of that slope for L2.

Given the equation of line L1: 3x + 2y = 12

Rearrange the equation to isolate y:

2y = -3x + 12

y = (-3/2)x + 6

The slope of L1 is -3/2.

Since L2 is perpendicular to L1, the slope of L2 is the negative reciprocal of -3/2, which is 2/3.

Using the slope-intercept form y = mx + c, where m is the slope and c is the y-intercept, we can write the equation of L2:

y = (2/3)x + c

To find c, we substitute the coordinates of the point (2,9) into the equation:

9 = (2/3)(2) + c

9 = 4/3 + c

c = 9 - 4/3

c = 27/3 - 4/3

c = 23/3

Therefore, the equation of line L2 in the form y = mx + c is:

y = (2/3)x + 23/3

(b)(i) To find the equation of line L3 parallel to line L1, we can use the same slope as L1, which is -3/2, and substitute the given point (-4,-1) into the point-slope form y - y1 = m(x - x1):

y - (-1) = (-3/2)(x - (-4))

y + 1 = (-3/2)(x + 4)

y + 1 = (-3/2)x - 6

y = (-3/2)x - 7

Therefore, the equation of line L3 in the form ax + by = c is:

(3/2)x + y = -7

(ii) To find the x-intercept of L3, we set y = 0 and solve for x:

0 = (-3/2)x - 7

(3/2)x = -7

x = (-7)(2/3)

x = -14/3

Therefore, the x-intercept of L3 is -14/3.

To find the y-intercept of L3, we set x = 0 and solve for y:

y = (-3/2)(0) - 7

y = -7

Therefore, the y-intercept of L3 is -7.

(iii) To find the point of intersection between L2 and L3, we can set the equations of L2 and L3 equal to each other and solve for x and y:

(2/3)x + 23/3 = (-3/2)x - 7

To solve for x:

Multiply both sides by 6 to eliminate the fractions:

4x + 46 = -9x - 42

4x + 9x = -42 - 46

13x = -88

x = -88/13

Substitute the value of x back into either equation to solve for y:

y = (2/3)(-88/13) + 23/3

y = -176/39 + 299/39

y = 123/39

y = 41/13

Therefore, the point of intersection between L2 and L3 is (-88/13, 41/13).

To evaluate for y₁ in the equation m = (y₂ - y₁) / (x₂ - x₁), we can apply algebraic manipulation to isolate y₁.
In the first step, we  multiply both sides of the equation by (x₂ - x₁) to eliminate the denominator. Therefore,
m(x₂ - x₁) = y₂ - y₁
In the second step, we can subtract y₂ from both sides of the equation to isolate y₁.
Therefore,

To determine the height of the building, we can use the           trigonometric relationship involving the angle of elevation, the height of the building, and the length of its shadow.

Let's denote the height of the building as h. The length of the shadow cast by the building is given as 68 ft, and the angle of elevation of the sun is 34 degrees.

Using the tangent function, we have the equation:
