Math Problems For 12th Graders

Question 1: Solve the following trigonometric equation for x in the interval [0, 2π]: 2sin^2(x) – 3sin(x) + 1 = 0

Answer 1: To solve the equation 2sin^2(x) – 3sin(x) + 1 = 0, we can factor it as follows: (2sin(x) – 1)(sin(x) – 1) = 0

Setting each factor to zero and solving, we get: 2sin(x) – 1 = 0 or sin(x) – 1 = 0

For the first equation, we have: 2sin(x) – 1 = 0 sin(x) = 1/2 x = π/6 or 5π/6

For the second equation, we have: sin(x) – 1 = 0 sin(x) = 1 x = π/2

So, the solutions in the interval [0, 2π] are x = π/6, π/2, and 5π/6.

Question 2: Determine the limit as x approaches infinity of the function f(x) = (3x^3 – 2x^2 + 5) / (4x^3 + 7x – 1).

Answer 2: To find the limit as x approaches infinity of the function f(x) = (3x^3 – 2x^2 + 5) / (4x^3 + 7x – 1), we need to compare the degrees of the numerator and denominator.

Since the degree of the numerator is 3 and the degree of the denominator is also 3, we can divide each term by the highest power of x, which is x^3.

Dividing the numerator and denominator by x^3, we get: f(x) = (3 – 2/x + 5/x^3) / (4 + 7/x^2 – 1/x^3)

As x approaches infinity, the terms 2/x and 5/x^3 go to zero, and the terms 7/x^2 and 1/x^3 also go to zero. Thus, the limit of f(x) as x approaches infinity is: f(x) = (3 – 0 + 0) / (4 + 0 – 0) = 3/4

Therefore, the limit of the function f(x) as x approaches infinity is 3/4.

Question 3: A car travels at a constant speed of 60 km/h. How far will it travel in 2.5 hours?

Answer 3: To determine the distance traveled by the car, we can use the formula: Distance = Speed × Time

In this case, the speed of the car is 60 km/h, and the time is 2.5 hours. Substituting the values into the formula, we get: Distance = 60 km/h × 2.5 hours Distance = 150 km Therefore, the car will travel a distance of 150 kilometers in 2.5 hours.

Question 4: Solve the quadratic equation: x^2 – 5x + 6 = 0

Answer 4: To solve the quadratic equation x^2 – 5x + 6 = 0, we can factor it as follows: (x – 2)(x – 3) = 0

Setting each factor to zero and solving, we get: x – 2 = 0 or x – 3 = 0 , For the first equation, we have: x –
