The boulder's maximum height is 242.6 feet.

It takes the boulder 3.79 seconds to reach its maximum height

Motion is the phenomenon in which an object changes its position with respect to time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed.

here, we have,

From the question, we are to determine the maximum height of the boulder

First, we will calculate the time it took the boulder to reach its maximum height

Using the formula,

v = u - gt

Where v is the final velocity

u is the initial velocity

g is the acceleration due to gravity (g = 32.1741 ft/s²)

and t is the time

From the given information

u = 122 ft/s

At maximum height, v = 0 ft/s

Putting the parameters into the equation, we get

0 = 122 - 32.1741t

32.1741t = 122

t = 3.79 s

This means it takes the boulder 3.79 seconds to reach its maximum height.

Now, substitute the value of t into the function that gives the height of the boulder

From the given information,

The height of the boulder is given by

H(t)= -16t² + 122t + 10

Then,

H(3.79) = -16(3.79)² + 122(3.79) + 10

H(3.79) = -229.8256 + 462.38 + 10

H(3.79) = 242.5544

H(3.79) ≅ 242.6 ft

Hence, the boulder's maximum height is 242.6 feet.

Answer:

737 cooks are required to prepare a meal for 737 people in 5 hours

Step-by-step explanation:

According to the given information, 10 cooks can prepare a meal for 536 people working for 8 hours each.

Let's calculate the total work done by the 10 cooks in 8 hours.

Total work done = Number of cooks * Hours worked

Total work done = 10 * 8 = 80

Now, let's calculate the work done by one cook in one hour.

Work done by one cook in one hour = Total work done / (Number of cooks * Hours worked)

Work done by one cook in one hour = 80 / (10 * 8) = 1

Therefore, one cook can prepare food for 1 person in 1 hour.

Now, let's calculate the number of cooks required to prepare a meal for 737 people in 5 hours.

Total work required = Number of people * Hours required

Total work required = 737 * 5 = 3685

Number of cooks required = Total work required / (Hours worked * Work done by one cook)

Number of cooks required = 3685 / (5 * 1) = 737

Therefore, 737 cooks are required to prepare a meal for 737 people in 5 hours.

Answer: The equation x = 7y + 2 is a linear equation in two variables, x and y. To find ordered pairs of x and y that satisfy this equation, we can choose values of y and then solve for x.

For example, if we choose y = 0, then:

x = 7y + 2

x = 7(0) + 2

x = 2

Therefore, the ordered pair (2, 0) satisfies the equation x = 7y + 2.

Similarly, if we choose y = 1, then:

x = 7y + 2

x = 7(1) + 2

x = 9

Therefore, the ordered pair (9, 1) satisfies the equation x = 7y + 2.

We can continue in this manner to find more ordered pairs. However, note that there are infinitely many ordered pairs that satisfy this equation, as the equation represents a line with a slope of 7 and a y-intercept of (0, 2). Therefore, we can choose any value of y and obtain a corresponding value of x that satisfies the equation.

The quantity provides the best measure of the television show’s popularity is the number of streams per episode.

We anticipate that independent variables will have an impact on dependent variables. What occurs as a result of the independent variable is referred to as a dependant variable.

The dependant variable is what changes as a result of the independent variable, which is what you modify.

The most accurate indicator of a television show's popularity on a streaming service is the number of streams each episode.

This is because, rather than just the length of the episodes or the number of episodes every season, the number of streams directly represents the number of viewers who are actively choosing to watch the show.

The number of streams also considers re-watchability and binge-watching, which are further indicators of how popular a show is.

To calculate the probability that Cindy will get at least 48 orange Stattles in her next 14 ounce bag, we need to use the binomial probability formula:

P(X >= 48) = 1 - P(X < 48)

Where

To calculate P(X < 48), we need to use the binomial probability formula:

P(X = x) = (nCx) * p^x * q^(n-x)

Where

nCx is the binomial coefficient, which can be calculated using the formula:

nCx = n! / (x! * (n-x)!)

where ! denotes the factorial function.

We can use a cumulative binomial distribution table or a binomial calculator to find the probability of getting less than 48 orange Stattles in a 14 ounce bag. For example, using an online calculator, we find that:

P(X < 48) = 0.871

Therefore, the probability that Cindy will get at least 48 orange Stattles in her next 14 ounce bag is:

P(X >= 48) = 1 - P(X < 48) = 1 - 0.871 = 0.129

The highest height of the ball, to the closest foot, is stated to be around 88 feet.

Velocity may be referred to as the speed when something moves toward a particular location. as the rate of a car driving northwest on a highway or the pace at which a rocket takes off.

The function h(t) = −16t² + v0t + h0 models the vertical motion of the ball, where t is time in seconds, v0 is the initial velocity in feet per second, and h0 is the initial height in feet.

In this case, the beginning height is 4 feet, and the velocity of the fluid equals 75 feet per second. As a result, the following outlines the function h(t) which it simulates the ball's vertical motion:

h(t) = -16t² + 75t + 4

The point of the concave function h must be located in order to determine the ball's peak (t) = -16t² + 75t + 4.

The t-coordinate of the vertex is given by t = -b/2a, where a = -16 and b = 75. Substituting these values, we get:

t = -75 / (2 x (-16)) = 2.34375

We enter this t quantity into the procedure h(t) to get the maximum height:

h(2.34375) = -16(2.34375)² + 75(2.34375) + 4 = 87.74

To the nearest foot, the ball therefore achieves a peak of 88 feet.

Since it doesn't make sense for Timothy to have negative money, we can conclude that there is no solution to this problem.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

Let's assume that Timothy has x dollars when he enters the first store.

According to the problem, he spends 1 dollar more than half of what he has.

So, the amount he spends in the first store is:

1/2 * x + 1

After spending this amount, he will have:

x - (1/2 * x + 1) = 1/2 * x - 1

dollars left.

He then goes to the second store and spends 1 dollar more than half of what he has left, which is:

1/2 * (1/2 * x - 1) + 1 = 1/4 * x + 1/2

After spending this amount, he will have:

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

dollars left.

He repeats this process for each of the five stores.

Therefore, the amount of money Timothy has left after visiting all five stores is:

1/4 * x - 3/2 - (1/4 * x + 1/2) - (1/4 * x + 1/2) - (1/4 * x + 1/2) - (1/4 * x + 1/2) = -5/4 * x - 5

Since he has spent all his money, the amount of money he has left must be 0:

-5/4 * x - 5 = 0

Solving for x, we get:

x = -20

However, since it doesn't make sense for Timothy to have negative money, we can conclude that there is no solution to this problem.

So what you need to do is split who is part of each:

1/2:

Wife:$?

1/2:

Daughter:$40,000

Butler:$?

Charity:$6,000

This makes it much easier to see as you know the charity and Butler received the same amount. You take your total (x) and do a simple equation of x=$40,000+6,000+6,000 as you know the butler must have also received the $6,000 the charity did. You will get x=$52,000 and you know that is half of the estate as he gave the other half to his wife. This is the same as knowing the butler and charity received the same amount as halves are equal to each other. SO now all you have to do is add $52,000+$52,000=$104,000 getting your answer.  

Answer:

Let's start by finding how much money Mary has left after buying the gift cards:

$250 - $130 = $120

Now, to find the greatest number of candy bars Mary can buy, we need to divide the amount of money she has left by the cost of each candy bar:

$120 ÷ $1.50 = 80

So Mary can buy up to 80 candy bars with the rest of her money.

We can check which inequality represents this situation by plugging in the numbers:

130 + 1.50x ≤ 250

where x represents the number of candy bars Mary buys.

If we subtract 130 from both sides, we get:

1.50x ≤ 120

Finally, if we divide both sides by 1.50, we get:

x ≤ 80

This matches our answer, so the correct inequality is:

D. 130 +1.50x ≤ 250

Answer:

D. 130 +1.50x ≤ 250

Step-by-step explanation:

Answer: To draw a trend line that models the given data set, we first need to plot the points on a graph. We can use a scale of 1 unit on the x-axis and 5 units on the y-axis to plot the points as follows:

(1, 27.5)    ●

(4, 35)      ●

(7, 42.5)    ●

(10, 50)     ●

(13, 57.5)   ●

We can see that the points roughly form a straight line. To find the equation of the trend line, we can use linear regression, which involves finding the line that best fits the data.

Using a calculator or software, we can find that the equation of the trend line is:

y = 3.5x + 24

This means that for every increase of 1 unit in x, y increases by 3.5 units. The y-intercept of the trend line is 24, which represents the value of y when x = 0.
