A. 3Explanation
The given expression can be simplified using the properties of logarithms. Using the property log(a) + log(b) = log(ab) and log(a) - log(b) = log(a/b), we can rewrite the expression as log(12^2) + log(10^2) - log(15^2). Simplifying further, we get log(144) + log(100) - log(225). Using the property log(a) - log(b) = log(a/b), we can rewrite the expression as log(144 * 100 / 225). Simplifying the numerator and denominator, we get log(64). The logarithm of 64 to the base 2 is equal to 6. Therefore, the answer is 3.Rate this question:

Correct Answer
A. 2x + y = 4Explanation
The equation of a straight line that passes through the point (3, -2) and is perpendicular to the line x - 2y + 2 = 0 can be found by using the fact that the slopes of perpendicular lines are negative reciprocals of each other. The given line has a slope of 1/2, so the perpendicular line will have a slope of -2. Using the point-slope form of a line, we can write the equation as y - (-2) = -2(x - 3), which simplifies to y + 2 = -2x + 6. Rearranging the equation, we get 2x + y = 4.Rate this question:

18.000 m
-
27.000 m
-
36.000 m
-
40.000 m
Correct Answer
A. 18.000 mExplanation
The equation given represents the height of the rocket as a function of time. To find the maximum height, we need to find the vertex of the parabolic function. The vertex can be found using the formula t = -b/2a, where a and b are the coefficients of the quadratic equation. In this case, a = -5 and b = 600. Plugging these values into the formula, we get t = -600 / (2*(-5)) = 60 seconds. Substituting this value back into the equation, we get h(60) = 600(60) - 5(60)^2 = 18,000 meters. Therefore, the maximum height reached by the rocket is 18,000 meters.Rate this question:

The given inequality is 2(x - 3) ≥ 4(2x + 3). Simplifying this inequality, we get 2x - 6 ≥ 8x + 12. Rearranging the terms, we have 6x ≤ -18. Dividing both sides by 6, we get x ≤ -3. Therefore, the solution set of the inequality is {x | x ≤ -3}.Rate this question:

Correct Answer
A. x + y ≤ 25; 3x + 4y ≤ 84; x ≥ 0; y ≥ 0Explanation
The correct answer is x + y ≤ 25; 3x + 4y ≤ 84; x ≥ 0; y ≥ 0. This is because the shaded region in the graph represents the feasible region where all the inequalities are satisfied. In this case, the shaded region is below the line x + y = 25 and below the line 3x + 4y = 84. Additionally, the region is also limited to the positive values of x and y, as indicated by x ≥ 0 and y ≥ 0. Therefore, the correct answer is the option that includes all these conditions.Rate this question:

Correct Answer
A. x + y ≤ 30; 5x + 4y ≥140 ; x ≥ 0; y ≥ 0Explanation
The given model represents the constraints for the problem correctly. The inequality x + y ≤ 30 represents the constraint on the total number of TVs that can be bought, which cannot exceed 30. The inequality 5x + 4y ≥ 140 represents the constraint on the total cost of the TVs, which must be at least 140. The inequalities x ≥ 0 and y ≥ 0 represent the non-negativity constraints, meaning that the number of TVs of each brand cannot be negative. Therefore, the given model accurately represents the problem.Rate this question:

The shaded area in the diagram represents the feasible region of the linear inequality system. The objective function f(x, y) = 3x + 2y represents a linear function that needs to be maximized. To find the maximum value, we need to find the point within the feasible region that yields the highest value for the objective function. By evaluating the objective function at each corner point of the feasible region, we can determine that the maximum value is 12.Rate this question:

The correct answer is iv because when we multiply a vector by a scalar, it means we are scaling the vector by that scalar. In this case, 2p means we are scaling vector p by a factor of 2. Adding q to 2p means we are combining the scaled vector p with vector q. Therefore, 2p + q represents the vector obtained by scaling vector p by 2 and then adding vector q to it.Rate this question:

Correct Answer
A. 604Explanation
The surface area of a cone can be calculated using the formula: A = πr(r + l), where r is the radius of the base and l is the slant height. In this case, the diameter of the base is given as 14 cm, so the radius is 7 cm. The slant height can be calculated using the Pythagorean theorem: l = √(r^2 + h^2), where h is the height of the cone. Substituting the given values, we get l = √(7^2 + 24^2) = √(49 + 576) = √625 = 25 cm. Plugging these values into the formula, we get A = π(7)(7 + 25) = 3.14(7)(32) = 703.36 cm^2. Rounded to the nearest whole number, the surface area is 704 cm^2.Rate this question:

Correct Answer
A. Jika Agus tidak lulus ujian maka nilai UN matematikanya kurang dari 5,00.Explanation
The correct answer is "Jika Agus tidak lulus ujian maka nilai UN matematikanya kurang dari 5,00." This is the inverse of the given statement. The original statement states that if Agus's math score on the national exam is greater than 5.00, then he passes the exam. The inverse of this statement is that if Agus does not pass the exam, then his math score on the national exam is less than 5.00.Rate this question:

Jika servis restoran tidak baik, maka restoran itu tidak mendapat untung.
-
Jika restoran ingin mendapat untung, maka servisnya baik.
-
Jika restoran itu tamunya banyak, maka servisnya baik.
-
Jika restoran servisnya tidak baik, maka tamunya tidak banyak
Correct Answer
A. Jika servis restoran baik maka restoran itu mendapat untungExplanation
The conclusion can be inferred from the premises because the first premise states that if the restaurant service is good, then the restaurant will have many customers. The second premise states that if the restaurant has many customers, then the restaurant will make a profit. Therefore, it can be concluded that if the restaurant service is good, then the restaurant will make a profit.Rate this question:

Correct Answer
A. VExplanation
The correct answer is v. The value of Sin 2A can be determined using the double angle formula for sine. Since A is an acute angle, we can use the formula Sin 2A = 2Sin A * Cos A. Given that Sin A = 3/4, we can substitute this value into the formula to get Sin 2A = 2 * (3/4) * (Cos A). Since A is an acute angle, Cos A is positive. Therefore, the value of Sin 2A is positive.Rate this question:

The correct answer is iii. (5, 5). This is because in polar coordinates, the first value represents the distance from the origin (5 units) and the second value represents the angle from the positive x-axis (45 degrees). To convert to Cartesian coordinates, we use the formulas x = r * cos(theta) and y = r * sin(theta). Plugging in the values, we get x = 5 * cos(45) = 5 * 0.7071 = 3.5355 and y = 5 * sin(45) = 5 * 0.7071 = 3.5355. Therefore, the Cartesian coordinates are (3.5355, 3.5355), which is equivalent to (5, 5) when rounded.Rate this question:

Correct Answer
A. 45Explanation
There are 6 men and 3 women, and the committee needs to consist of 3 men and 2 women. The number of ways to choose 3 men from 6 is given by the combination formula C(6,3) = 6! / (3! * (6-3)!) = 20. Similarly, the number of ways to choose 2 women from 3 is C(3,2) = 3! / (2! * (3-2)!) = 3. Therefore, the total number of ways to form the committee is 20 * 3 = 60. However, since the order of selection does not matter, we need to divide by the number of ways to arrange the committee members, which is 2! = 2. Therefore, the final answer is 60 / 2 = 30.Rate this question:

The correct answer is v. The question asks for the probability of getting a sum of 9 when two dice are rolled together.

There are 4 ways to get a sum of 9: (3,6), (4,5), (5,4), and (6,3). Since there are 36 possible outcomes when two dice are rolled (6 possible outcomes for each dice), the probability of getting a sum of 9 is 4/36, which can be simplified to 1/9.

The correct answer is iii. The question asks for the standard deviation of the data set 4, 5, 6, 7, 8. Standard deviation is a measure of how spread out the data is from the mean. To calculate the standard deviation, we first find the mean of the data set, which is (4+5+6+7+8)/5 = 6. Then, we subtract the mean from each data point, square the result, and find the average of these squared differences. Finally, we take the square root of this average to get the standard deviation. The standard deviation of the given data set is approximately 1.58.Rate this question:
