In a Bridge span, 19 beams are equally spaced. From the center of the first beam to the center of the last beam, it measures 204.75' . What is the center-to-center spacing between the beams?

The measure of v is 61 degree.

We have,

Interior angle = (v - 19) or v

Exterior angle = v + 42

Using exterior Angle Property

Exterior angle= Sum of opposite interior angle

v + 42 = v - 19 + v

v + 42 = 2v - 19

v - 2v = -19 - 42

-v = -61

v= 61

Thus, the value of v is 61.

By evaluating the function related to the second derivative f''(x) = - 25 · sin 5x is equal to f(π / 5) = (14π - 50) / 25.

In this question we find the definition of the second derivative of a function, this function must be found by integrals and initial values. First, write the entire function:

f''(x) = - 25 · sin 5x

Second, determine the first derivative:

f'(x) = (1 / 5) · cos 5x + C₁

f(0) = (1 / 5) · cos 0 + C₁

3 = 1 / 5 + C₁

C₁ = 14 / 5

f'(x) = (1 / 5) · cos 5x + 14 / 5

Third, determine the function:

f(x) = (1 / 25) · sin 5x + (14 / 5) · x + C₂

f(0) = (1 / 25) · sin 0 + (14 / 5) · 0 + C₂

- 2 = (1 / 25) · sin 0 + (14 / 5) · 0 + C₂

- 2 = C₂

f(x) = (1 / 25) · sin 5x + (14 / 5) · x - 2

Fourth, evaluate the function:

f(π / 5) = (1 / 25) · sin π + (14 / 5) · (π / 5) - 2

f(π / 5) = 14π / 25 - 2

The equation has a slope of 2/3 and the y-intercept is -1. The graph is aatched with the answer below.

An equation of a line is a mathematical expression that describes the relationship between the x and y coordinates of all the points on a straight line. It takes the form y = mx + b, where m is the slope of the line and b is the y-intercept (the point where the line intersects the y-axis). This equation allows us to easily calculate the y-coordinate of any point on the line, given its x-coordinate.

A linear graph, also known as a straight-line graph, is a graph that represents a linear equation. The x and y coordinates of each point on the line are plotted on a graph, with the x values on the horizontal axis and the y values on the vertical axis.

The resulting graph is a straight line that passes through the y-intercept (the point where the line intersects the y-axis) and has a slope equal to the coefficient of x in the equation.

Linear graphs are useful in many fields, including mathematics, science, engineering, economics, and business, as they allow us to visualize and analyze relationships between two variables that are directly proportional to each other.

The length of Tim's deck is 1/15th of the length of Al's deck.

Finding the expressions for the length of each deck.

For Al's deck:

Area of a rectangle = length × width

60x + 40 = length × 4

length = (60x + 40) / 4

length = 15x + 10 ft

For Tim's deck:

Area of a rectangle = length × width

21x + 14 = length × 7

length = (21x + 14) / 7

length = 3x + 2 ft

Now we can find no. of times the length of Tim's deck is Al's deck by dividing the length of Al's deck by the length of Tim's deck:

(15x + 10) / (3x + 2)

Simplifying this expression:

(3(5x + 3) + 1) / (3x + 2)

(3(5x + 3) / (3x + 2)) + (1 / (3x + 2))

15 + (1 / (3x + 2))

Therefore, the length of Tim's deck is 1/15th of the length of Al's deck.

Result:

The probability of getting a sum greater than 25 = 1/9.

The answer is not among the given options.

To find the probability, we would need to consider the possible combinations of the spinner and number cube that result in a sum greater than 25.

First, note that the highest possible sum we can get is 12 (that is 6 from the spinner and 6 from the number cube). Therefore, we can remove all combinations that result in a sum of 24 or less.

Next, we can consider the combinations that result in a sum of 25 like this:

Spinner lands on 6, number cube lands on 5

Spinner lands on 5, number cube lands on 6

Spinner lands on 6, number cube lands on 4

Finally, we can consider the combinations that result in a sum greater than 25:

Spinner lands on 5, number cube lands on 5

Spinner lands on 6, number cube lands on 5

Spinner lands on 5, number cube lands on 6

Spinner lands on 6, number cube lands on 6

Here, 4 possible combinations can result in a sum greater than 25 from a total of 6 x 6 = 36 possible outcomes.

So, the probability of getting a sum greater than 25 is 4/36 = 1/9.

Therefore, none of the given answer choices matches this result.

The coordinates of endpoint T are (5,18).

The midpoint formula is expressed as:

Midpoint = [(x₁ + x₂)/2, (y₁ + y₂)/2]

Where (x₁, y₁) and (x₂, y₂) are the coordinates of the two endpoints of the line segment.

Let's call the coordinates of point T (x,y).

Since S is the midpoint of RT, we can use the midpoint formula to find the coordinates of S:

Midpoint = [(x₁ + x₂)/2, (y₁ + y₂)/2]

((13+x)/2, (-8+y)/2) = (9,5)

Solving for x:

(13+x)/2 = 9

13 + x = 2 × 9

13 + x = 18

x = 18 - 13

x = 5

Solving for y, we get:

(-8+y)/2) = 5

-8 + y = 5 × 2

-8 + y = 10

y = 10 + 8

y = 18

Answer:

The 80.6 square foot roll is less expensive per square foot since it costs $0.03/square foot compared to the other which costs $0.02/square foot

Step-by-step explanation:

Because the question asks which of the two paper towel rolls is less expensive per square foot, we must find the unit rate of both rolls (specifically, cost per 1 square foot)

We can find the unit rate using a proportion:

53.7 square foot roll

[tex]\frac{1.49}{53.7}=\frac{x}{1} \\1.49=53.7x\\0.0277=x\\0.03=x[/tex]

80.6 square foot roll

[tex]\frac{1.89}{80.6}=\frac{x}{1} \\1.89=80.6x\\0.0234=x\\0.02=x[/tex]

Thus, per square foot, the 80.6 square foot roll is less expensive than the 53.7 square foot roll

There are 6 such paths, so there are 6 outcomes in the sample space that show Casey winning.

We can use a tree diagram to visualize the different outcomes of Casey's rolls:

Each branch of the tree represents one roll of the number cube.

The first two rolls are independent and equally likely to be any of the six numbers.

If the first two rolls are the same number, then Casey gets to roll again. If the third roll is a 6, she wins.

We can count the number of outcomes in the sample space that show Casey winning by counting the number of paths in the tree that lead to a 6 on the third roll.

These are:

1-1-6

2-2-6

3-3-6

You want to know the number of hours Liz worked at each job, when the total pay for a total of 28 hours work was $175.80. Job A paid $6 per hour, and job B paid $6.60 per hour.

We can let 'b' represent the number of hours worked at job B. Then (28-b) is the number of hours worked at job A. Liz's total pay was ...

  6(28 -b) +6.60(b) = 175.80

Simplifying the equation gives ...

  0.60b +168.00 = 175.80

  0.60b = 7.80 . . . . . . . . . . . subtract 168

Answer:

Since the first blue marble is replaced before the second draw, the probability of drawing a blue marble on the second draw is still 3/8, the same as the probability of drawing a blue marble on the first draw.

To find the probability of both events occurring, we can multiply the probabilities of each event:

P(drawing two blue marbles in a row) = P(drawing a blue marble on first draw) x P(drawing a blue marble on second draw)

P(drawing two blue marbles in a row) = (3/8) x (3/8)

P(drawing two blue marbles in a row) = 9/64

Therefore, the probability of drawing two blue marbles in a row is 9/64.

Initially the graph f (x) is shifted horizontally to the right.

When the graph shifts to right the function then becomes

f (x) → f (x-b)

Where b is the units by which it is shifted towards right .

So, in the figure we can see that it is shifted 2 units to the right .

So, f(x) → f(x-2)

Since f(x) is,
