The magnitude of the resultant force is given by:

|F| = [tex]sqrt((-7)^2 + 0^2) N|F| = 7 N[/tex]The direction of the resultant force is given by:

[tex]θ = tan^-1(0/-7)θ = tan^-1(0) = 0[/tex]

Therefore, the magnitude of the resultant force is 7 N, and its direction is along the negative x-axis.

1. Cartesian vector expression for five forcesThe five forces acting along the edges of a pentagon plate ABC are shown below:Force acting on AB = (6i + 6j) NForce acting on BC = (8i + 4j) NForce acting on CD = (-5i + 10j) NForce acting on DE = (-10i - 8j) NForce acting on EA = (4i - 12j) N2.

Cartesian vector expression of the resultant force of these five forcesThe resultant force acting on the pentagon plate ABC can be determined by finding the vector sum of the five forces. The cartesian vector expression of the resultant force can be found as follows:[tex]F = F1 + F2 + F3 + F4 + F5F = (6i + 6j) N + (8i + 4j) N + (-5i + 10j) N + (-10i - 8j) N + (4i - 12j) N= (-7i + 0j) N[/tex]

Therefore, the cartesian vector expression of the resultant force is (-7i + 0j) N.3. Magnitude and direction of the resultant forceThe magnitude and direction of the resultant force can be determined by using the cartesian vector expression of the resultant force obtained in the previous step.

The probability that a student chosen at random likes science given that he or she likes art is 41.4%

In our case, we want to find P(Science|Art), which is the probability of a student liking science given that he or she likes art. Using Bayes' theorem, we have:

P(Science|Art) = P(Art|Science) x P(Science) / P(Art)

We know that P(Art) = 0.35 and P(Science|Art) = 0.22. To find P(Art|Science), we can use the formula:

P(Art|Science) = P(Science|Art) x P(Art) / P(Science)

We don't know P(Science) yet, but we can calculate it using the fact that:

P(Science) = P(Science|Art) x P(Art) + P(Science|Not Art) x P(Not Art)

where P(Not Art) is the probability that a student does not like art, which is 1 - P(Art) = 0.65. We are given that P(Science|Not Art) = 0.15, which is the probability that a student who does not like art likes science. Substituting these values, we get:

P(Science) = 0.22 x 0.35 + 0.15 x 0.65 = 0.1855

Now we can substitute all the values into Bayes' theorem:

P(Science|Art) = 0.22 x 0.35 / 0.1855 = 0.414 or 41.4%

So the coordinates of point X' after dilation are (15, 11).

Polygon WXYZ is dilated by a scale factor of 3, with vertex W as the center of dilation. This means that the distances from vertex W to the other vertices are multiplied by 3, while W remains unchanged. Given the coordinates of point W are (3,2) and point X are (7,5), we can find the coordinates of point X' after dilation.

To do this, first determine the change in the x and y coordinates from point W to point X:

Δx =[tex]7 - 3 = 4\\[/tex]
Δy =[tex] 5 - 2 = 3[/tex]

Now multiply these changes by the scale factor of 3:

There is evidence of a statistically significant difference in the yields between fertilizer A and fertilizer B (0.01 < p < 0.05).

Step-by-step explanation:

Katherine's hike was 4.7 hours long. She spent 1 hour and 42 minutes going uphill, which was 20% of her hike. This means that her entire hike was (1 hour and 42 minutes) / (20%) = 4.7 hours long.

To calculate this, we need to divide the amount of time spent hiking uphill (1 hour and 42 minutes) by the percentage of her hike spent going uphill (20%). 1 hour and 42 minutes is equal to 102 minutes. 102 minutes / 20% = 4.7 hours. Therefore, Katherine's hike was 4.7 hours long.

We can use the following equation to calculate the answer:

Hike time = (uphill time) / (percentage of uphill time)

Hike time = (102 minutes) / (20%) = 4.7 hours

It is important to note that the calculation can also be done using the amount of time spent going downhill as well. The amount of time spent going downhill will equal the total hike time minus the amount of time spent going uphill. In this case, the amount of time spent going downhill would equal 4.7 hours - 1 hour and 42 minutes = 2.28 hours.

Answer:

The volume of a sphere is given by the formula:

V = (4/3)πr^3

where r is the radius of the sphere.

Since the diameter of Casper's balloon is 6 inches, the radius is 3 inches. Therefore, the volume of Casper's balloon is:

V1 = (4/3)π(3 inches)^3 = 113.1 cubic inches (approx.)

We know that Casper's balloon is seven times the volume of his brother's balloon. Let's call the volume of his brother's balloon V2. We can set up an equation:

V1 = 7V2

Substituting the value of V1, we get:

113.1 cubic inches = 7V2

Dividing both sides by 7, we get:

V2 = 16.2 cubic inches (approx.)

Therefore, the approximate volume of Casper's brother's balloon is 16.2 cubic inches.

The tank contains 1050 milliliters of water when full or 1.05 liters.

To calculate the volume of the tank in milliliters, we multiply the length (15 cm), width (7 cm), and height (10 cm) together:

15 cm x 7 cm x 10 cm = 1050 cm³

Since 1 milliliter equals 1 cubic centimeter (cm^3), we know that the tank can hold 1050 milliliters of water.

To convert milliliters to liters, we can divide the volume in milliliters by 1000:

1050 mL ÷ 1000 = 1.05 L

Therefore, when full, the tank can hold 1050 milliliters of water or 1.05 liters.

Rent-A-Reck Incorporated should charge $95 to maximize its revenue and the company will rent 45 cars at a price of $95.

To determine the price that will maximize Rent-A-Reck Incorporated's revenue, we need to consider the relationship between the price of renting a car and the number of cars that are rented.

Based on the information provided, we know that the demand for rental cars decreases as the price increases. Specifically, for each $5 increase in price, two fewer cars will be rented.

Let's denote the price of renting a car as P and the number of cars rented as Q. Then we can express the relationship between price and quantity as:

Q = 60 - 2(P - 80)/5

This equation tells us that as the price P increases, the number of cars rented Q decreases. We can also use this equation to find the price that will maximize revenue. Revenue is calculated by multiplying the price by the number of cars rented, so we can write the revenue function as:

R = P(Q) * Q

= P * (60 - 2(P - 80)/5)

To find the price that maximizes revenue, we need to find the value of P that makes R as large as possible. One way to do this is to take the derivative of R with respect to P and set it equal to zero:

dR/dP = (60 - 2(P - 80)/5) - 2P/5 = 0

Solving for P, we get:

P = $95

To find the number of cars that will be rented at this price, we can substitute P = $95 into the demand equation:

Q = 60 - 2($95 - $80)/5

= 45

The inequality that represents the possible weight of the Maine Coon is 828 ≤ x ≤ 840

Let x be the weight of Linda's Maine Coon in pounds.

Since the difference in weight between the two cats is at least 6 pounds, we can write the following inequality:

|x - 834| ≥ 6

This inequality can be interpreted as "the absolute value of the difference between the weight of the Maine Coon and 834 pounds is greater than or equal to 6".

Simplifying the inequality, we get:

-6 ≤ x - 834 ≤ 6

Adding 834 to each side of the inequality, we get:

828 ≤ x ≤ 840

Therefore, the possible weight of Linda's Maine Coon is between 828 and 840 pounds, inclusive.

The bottom of the ladder is moving at a rate of 1.333 ft/sec when the top is 8 ft from the ground

The bottom of the ladder is moving at a rate of 6 ft/sec when the top is 8 ft from the ground. This can be found by using the equation v = d/t, where v is the velocity, d is the distance, and t is the time. The distance is 8 feet (from the top of the ladder to the ground) and the time is 1/6 seconds (since the ladder is sliding down at a rate of 6 ft/sec). Therefore, the velocity of the bottom of the ladder when the top is 8 ft from the ground is 8/1/6 = 8/6 = 4/3 = 1.333 ft/sec.

To understand this concept more clearly, imagine a ball rolling along the ground. Its velocity is constant until it hits a slope and begins to move down the slope. At this point, its velocity increases as it moves further down the slope, and its velocity is higher when it is further down the slope.

This is the same concept as the ladder sliding down the wall; the bottom of the ladder is moving faster than the top, so the velocity of the bottom of the ladder increases as the top of the ladder gets closer to the ground.

In conclusion, the bottom of the ladder is moving at a rate of 1.333 ft/sec when the top is 8 ft from the ground. This can be found using the equation v = d/t, where v is the velocity, d is the distance, and t is the time. The distance is 8 feet and the time is 1/6 seconds since the ladder is sliding down at a rate of 6 ft/sec.

Put the function into desmos and create a table.

Siona bought 7 shirts and 3 pairs of shorts when she spent a total of $36.50. The problem can be solved using a system of equations.

Let's use a system of equations to solve this problem:

Let x be the number of shirts that Siona bought, and y be the number of pairs of shorts that she bought. Then we have:

Equation 1: x + y = 10 (Siona bought 10 outfits in total)

Equation 2: 3.50x + 4.00y = 36.50 (The total cost of the outfits is $36.50)

To solve for x and y, we can use substitution or elimination. Let's use substitution:

From Equation 1, we can solve for x in terms of y:

x = 10 - y

Substitute this expression for x into Equation 2:

3.50(10 - y) + 4.00y = 36.50

Simplify and solve for y:

35 - 3.50y + 4.00y = 36.50

0.50y = 1.50

y = 3

Now we can substitute y = 3 back into Equation 1 to solve for x:

x + 3 = 10

x = 7

Therefore, Siona bought 7 shirts and 3 pairs of shorts when she spent a total of $36.50.
