The given function is t(x) = 2x³ + 30x² + 144x - 1. The first derivative of the given function is: t'(x) = 6x² + 60x + 144. The critical numbers of a function are those values of x for which either t'(x) = 0 or t'(x) is undefined. Here, the first derivative of the function exists for all values of x.
Hence, critical numbers occur only at the values of x where t'(x) = 0.So,t'(x) = 6x² + 60x + 144= 6(x² + 10x + 24)= 6(x + 4)(x + 6)∴ t'(x) = 0 when x = - 4 and x = - 6. Thus, the critical numbers of the function are x = - 6 and x = - 4.
According to the First Derivative Test, a function has a local maximum at a critical number x = c if the sign of the first derivative changes from positive to negative at x = c. Similarly, a function has a local minimum at a critical number x = c if the sign of the first derivative changes from negative to positive at x = c.
Therefore, the given function has a local maximum at x = - 6 and a local minimum at x = - 4.
Hence, the correct option is (d) There is a local maximum at x = - 6 and a local minimum at x = - 4.

An artist creates a right prism whose bases are regular pentagons. He wants to paint How many cans the lateral surfaces of the prism. One can of paint can cover 30 ft of paint aust h betyhe eight of the prism is 15 ft and the length of each side of the pentagon is 3 1t?
The surface area of the first prism is approximately 72.54 square meters. The surface area of the second prism is approximately 299.2 square cm. The surface area of the third prism cannot be calculated due to missing information. The amount of cardboard used to make the box is 856 square inches. Approximately 7.5 cans of paint are needed to paint the lateral surfaces of the prism.
To find the surface area of each prism, we need to calculate the sum of the areas of all its faces. Let's go through each prism one by one:
Prism 1: The dimensions given are 6 ft, 10 m, 5 ft, and 5 m. Since the units are different, we need to convert them to the same unit. Let's convert the feet to meters. 6 ft is approximately 1.83 m and 5 ft is approximately 1.52 m. Now, we can calculate the surface area using the formula for a rectangular prism: 2lw + 2lh + 2wh. Plugging in the values, we get: 2(1.83)(10) + 2(1.83)(1.52) + 2(10)(1.52) = 36.6 + 5.54 + 30.4 = 72.54 square meters.Prism 2: The prism is classified as a regular hexagonal prism. The lateral area of a prism is the sum of the areas of its lateral faces. Since the bases are regular hexagons, we can calculate the area of each base using the formula for the area of a regular hexagon: (3√3/2)(side length)^2. Plugging in the values, we get: (3√3/2)(4)^2 = 41.6 square cm. The sum of the areas of the bases is 2(41.6) = 83.2 square cm. To find the surface area, we also need to calculate the lateral area. The lateral area of a prism is the perimeter of the base multiplied by the height. The perimeter of a regular hexagon is 6 times the length of one side. Plugging in the value, we get: 6(4) = 24 cm. The lateral area is then 24 cm multiplied by the height, which is 9 cm. Multiplying, we get: 24(9) = 216 square cm. Finally, we can find the surface area by adding the sum of the areas of the bases and the lateral area: 83.2 + 216 = 299.2 square cm.Prism 3: The dimensions given are 4 m, 9.0.0.a, and 3 m. Since the units are not specified for the second dimension, we cannot calculate the surface area.Now, let's move on to the box:
The dimensions of the box are given as 10 in. wide, 12 in. high, and 14 in. deep. To find the surface area, we need to calculate the sum of the areas of all its faces. Using the formula for a rectangular prism, we get: 2(10)(12) + 2(10)(14) + 2(12)(14) = 240 + 280 + 336 = 856 square inches. Therefore, 856 square inches of cardboard is used to make the box.
Finally, let's calculate the amount of paint needed for the prism:
The prism has regular pentagonal bases. The height of the prism is given as 15 ft, and the length of each side of the pentagon is 3 ft. To find the lateral surface area, we need to calculate the perimeter of the base and multiply it by the height. The perimeter of a regular pentagon is 5 times the length of one side. Plugging in the value, we get: 5(3) = 15 ft. The lateral surface area is then 15 ft multiplied by the height, which is 15 ft. Multiplying, we get: 15(15) = 225 square ft. Since one can of paint can cover 30 square ft, we divide the lateral surface area by the coverage of one can: 225/30 = 7.5 cans. Therefore, approximately 7.5 cans of paint are needed to paint the lateral surfaces of the prism.

Answer:

Step-by-step explanation:
two counterfeit coins of equal weight are mixed with 8 identical genuine coins. the weight of each of the counterfeit coins is different from the weight of each of the genuine coins. a pair of coins is selected at random without replacement from the 10 coins. a second pair is selected at random without replacement from the remaining 8 coins. the combined weight of the first pair is equal to the combined weight of the second pair. what is the probability that all 4 selected coins are genuine? (2011amc10a problem 21) (a) 11 7 (b) 13 9 (c) 11 15 (d) 15 19 (e) 15
The probability that all 4 selected coins are genuine is 2/7
There are two cases where the combined weight of the first pair is equal to the combined weight of the second pair
Case 1: Both pairs consist of two genuine coins.
Case 2: One pair consists of two counterfeit coins and the other pair consists of two genuine coins.
Let's calculate the probability of each case separately
Case 1: The probability of selecting two genuine coins from 8 is (8/10) × (7/9) = 28/45 for the first pair, and (6/8) × (5/7) = 15/28 for the second pair (after one genuine coin has been selected from the first pair). Therefore, the probability of selecting two genuine coins for both pairs is (28/45) × (15/28) = 7/15.
Case 2: The probability of selecting two counterfeit coins from 2 and two genuine coins from 8 is (2/10) × (1/9) × (8/8) × (7/7) = 1/45 for the first pair, and (1/8) × (7/7) × (6/6) × (5/5) = 1/8 for the second pair (after one counterfeit coin has been selected from the first pair). There are two ways to select which pair consists of the counterfeit coins, so the total probability for this case is 2 × (1/45) × (1/8) = 1/180.
Therefore, the total probability of selecting two pairs with the same combined weight is (7/15) + (1/180) = 49/90. Since all four selected coins are genuine only in Case 1, the probability that all 4 selected coins are genuine is (7/15) / (49/90) = 14/49 = 2/7.

In terms of relative growth rate, what is the defining property of exponential growth?
In terms of relative growth rate Exponential growth is characterized by a constant relative growth rate.
Exponential growth is the process of increasing quantity over time. Occurs when the instantaneous rate of change of a quantity over time is proportional to the quantity itself. The exponential growth model has the form
y (t) = C eᵏᵗ, where k is the rate constant.
Relative Growth Rate:Relative growth rate (RGR) is the rate of growth relative to size. That is, the rate of growth per unit time relative to the size at that point in time and y'(t)/y(t) is the relative growth rate of a function y at time t.
1/y dy/dt = 1/y d(C eᵏᵗ)/dt
= 1/y(kC eᵏᵗ)
= 1/y ( ky) ( since, y (t) = C eᵏᵗ)
= k
Therefore a constant relative growth rate.

The lengths of the sides of a rectangular prism are positive integers. The total sum of the numerical values of its volume, total surface area, and the sum of the lengths of all its edges is 2015. What is the volume of the rectangular prism
The volume of the rectangular prism is 1435.
To find the volume of the rectangular prism, we need to consider the given information that the sum of its volume, total surface area, and the sum of the lengths of all its edges is equal to 2015. By analyzing the properties of a rectangular prism, we can determine the possible combinations of side lengths that satisfy the given condition.
Let's denote the side lengths of the rectangular prism as a, b, and c. The volume of a rectangular prism is given by V = a * b * c, the total surface area is given by A = 2(ab + ac + bc), and the sum of the lengths of all the edges is given by E = 4(a + b + c).
According to the problem statement, we have the equation V + A + E = 2015. Substituting the formulas for V, A, and E, we get:
a * b * c + 2(ab + ac + bc) + 4(a + b + c) = 2015.
By rearranging the equation, we have:
abc + 2ab + 2ac + 2bc + 4a + 4b + 4c = 2015.
Factoring out common terms, we get:
(a + 2)(b + 2)(c + 2) = 2015 + 8 = 2023.
Now, we need to analyze the factors of 2023 to find the possible combinations of side lengths. The factors of 2023 are 1, 7, 17, and 119. We can write (a + 2), (b + 2), and (c + 2) as these factors.
By examining the factors, we find that the combination (a + 2) = 1, (b + 2) = 7, and (c + 2) = 289 satisfies the condition. Solving these equations, we get a = -1, b = 5, and c = 287.
Since the lengths of a rectangular prism cannot be negative, we discard the solution with a = -1. Thus, the valid solution is a = 1, b = 5, and c = 287.
Finally, we can calculate the volume using the formula V = a * b * c:
V = 1 * 5 * 287 = 1435.
Therefore, the volume of the rectangular prism is 1435.

Solve for n. −2(n − 3.5) > 15 n > −4 n < −4 n > 4 n < 4
Answer: N > -4
Step-by-step explanation:
Cuz It's Right
The solution for inequality is n < -4.
The given inequality is −2(n − 3.5) > 15
An inequality will have the sign < , > , ≥ or ≤ instead of an equality in an equation. That is, an inequality compares two quantities on either sides of the inequality sign.
We are asked to solve the inequality −2(n − 3.5) > 15. That is, to find the possible values for n.
−2(n − 3.5) > 15
Dividing throughout by 2,
-(n - 3.5) > 15/2
⇒ -n +3.5 > 7.5
Subtracting 3.5 from both sides,
⇒ -n > 7.5 - 3.5
⇒ -n > 4
Multiply -1 on both sides of the inequality and the inequality will be reversed,
⇒ n < -4 is the solution for n.
The solution is the values of n less than -4.

Given the topological spaces X = {D, O, R, K} with the topology Tx and Y = {M, A, T, H} with the topology Jy, we are asked to determine whether the set E = {0, K} is open in X and open in Y.
To determine whether the set E = {0, K} is open in the topological spaces X and Y, we need to check if E belongs to the respective topologies, Tx and Ty.
In X, the topology Tx is given by: Tx = {Ø, {0}, {D, O}, {O, R}, {D, O, R}, X}. We can see that E = {0, K} is not explicitly listed in Tx. Therefore, E is not open in X since it does not belong to the topology.
In Y, the topology Ty is given by: Jy = {0, {M}, {M, A}, {M, A, T}, Y}. Again, E = {0, K} is not explicitly listed in Ty. Hence, E is not open in Y as it does not belong to the topology.
In both cases, the set E = {0, K} is not open in the respective topological spaces X and Y because it is not a member of the defined topologies.
