The  equation of the tangent plane to the parametric surface is 3x + 2y + 6 root2z = 0.

A tangent to a curve was a line that just touched the curve at that point and was "parallel" to the curve at that point. A well-tangent plane to a surface is a plane that just touches the surface at that point and is "parallel" to the surface at that point.

The tangent plane to surface S at point P0 includes all tangents to curves in S that pass through P0. For a plane tangent to a surface to exist at a point on that surface, it is sufficient if the function defining the surface is differentiable at that point.

The error that Vera made is she used the wrong number in her inequality to claimed the solution set on the number line represents the inequality.

In mathematics, "inequality" refers to a connection between two expressions or values that are not equal to one another. The equation-like form of the formula 5x 4 > 2x + 3 has an arrowhead in lieu of the equals sign. It is an illustration of inequity. This shows that the left half, 5x 4, is bigger than the right part, 2x + 3. Finding the x numbers for which the inequality holds true is what we are most interested in. An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.

Answer:

178.7 ft.

Step-by-step explanation:

The kite is (x + 5) ft above the ground. So we need to find x first.

Use the trigonometric identity Sine.

\(Sin\ \theta=\frac{perpendicular}{hypotenuse}\\\\sin44=\frac{x}{250} \\\\x=250*sin44\\x=250*0.69\\x=173.66\ ft\\\)

Rounding your answer to the nearest tenth would be 173.7 ft.

Now the kite is above the ground x + 5 which means

173.7 + 5 = 178.7 ft.

Given:

Height of the tree

To find the height of the tree, we use ratio/proportion.

So, we let x be the height of the tree and use the formula:

Height of man/length of man's shadow = x/length of the tree's shadow

Therefore ,the height of the tree is 20 ft.

The interest she earn in 7years is £287

Compound interest is the interest you earn on interest. This can be illustrated by using basic math: if you have $100 and it earns 5% interest each year, you'll have $105 at the end of the first year. At the end of the second year, you'll have $110.25.

The total amount to earn after a specified time if compound interest is :

A = P( 1+r/100)^t

where P is the principal, r is the rate and t is the time

A= 700( 1+ 5/100)⁷

A = 700( 1+0.05)⁷

A = 700(1.05)⁷

A= 700× 1.41

A = £ 987

interest =Amount - Principal

I = 987-700

I = £287

Person B will decide to exchange lands if the product of areaA and priceB is greater than the product of areaB and priceA.

To determine whether Person B should exchange their land with Person A, we need to compare the values of the two land parcels. The decision can be made based on the financial value of the lands, considering the size and price per square meter.If Person B's land has an area of areaB and a price of priceB per square meter, and Person A's land has an area of areaA and a price of priceA per square meter, Person B should compare the two products: areaA * priceB and areaB * priceA.

If the product of areaA and priceB is greater than the product of areaB and priceA (areaA * priceB > areaB * priceA), it means that the value of Person A's land is higher than that of Person B's land. In this case, Person B should decide to exchange their land with Person A.On the other hand, if areaA * priceB is less than or equal to areaB * priceA (areaA * priceB <= areaB * priceA), it indicates that the value of Person B's land is higher than or equal to that of Person A's land. Therefore, Person B should not exchange their land in this situation.

The program would take input from Person B for the area and price of both lands, perform the comparison mentioned above, and output the decision: "Yes, I like to exchange" or "No, I do not like to exchange" based on the result of the comparison.Therefore, Person B will decide to exchange lands if the product of areaA and priceB is greater than the product of areaB and priceA.

 num_gold_marbles = 0

 for _ in range(num_trials):

   marble = random.choice(["gold", "red", "blue", "green"])

   if marble == "gold":

     num_gold_marbles += 1

 return num_gold_marbles / num_trials

def main():

 num_trials = 10000

 probability = simulate_pulling_gold_marble(num_trials)

 print("The probability of pulling a gold marble is", probability)

if __name__ == "__main__":

 main()

This code simulates pulling a gold marble 10,000 times. Each time a marble is pulled, it is put back in the bag so that the probability of pulling a gold marble remains the same each time. The code then calculates the proportion of times a gold marble was pulled and prints the probability.

To run the simulation, you can save the code as a Python file and then run it from the command line.

Based on the given information, Jane should not search for the doll any more. The cost of searching outweighs the potential savings she might gain by finding a lower price.

In this scenario, Jane has already visited one shop and found the doll priced at $100. She knows that the doll is offered at three different prices: $120, $100, and $80, with unknown probabilities (represented as odds). Each additional search incurs a cost of $5.

To determine whether Jane should search for the doll again, we need to compare the expected cost of searching with the potential savings. Given the information provided, we do not have the probabilities associated with each price, so we cannot calculate the exact expected savings. However, we can make an informed decision based on the given information.

Since the current price of the doll is $100 and the potential savings from finding a lower price are uncertain, Jane should consider the cost of searching. With a search cost of $5 per search, it is unlikely that the potential savings from finding a lower price would offset the additional cost incurred by searching. Therefore, it is advisable for Jane not to search for the doll any more, as the cost of searching exceeds the expected savings.

It's important to note that a definitive decision would require more information, such as the probabilities associated with each price. However, based on the given information, the best course of action for Jane is to refrain from further searching.
