Answer:
A
Explanation:
You must know the basics of Trigonometry to solve this.
First, you must know that
lies in the second quadrant, so sin is negative.
Next, since
pi/4, is the reference angle of 3 pi/4, this means that we can set up a right triangle with pi/4 as an angle, we get
So the answer is A

Answer:
Son
Explanation:
Just got 100%, but further explanation: Es and esta are both easy to rule out, as neither of them refers to "they" (Alan y Enrique), and estan does not work because of the weird rules. Tbh I feel like you just have to memorize them except in some cases where one just clearly makes more sense than the other.
To find the values of a and b, we can use the given information about the function f(x) and its derivatives at x = 0.
First, we know that the value of f(0) is 1, which means that when we plug x = 0 into the function, we get f(0) = 20 + a0 + b*0^2 - 0 + 2 = 1. Solving this equation for b, we get b = -1.
Next, we know that the derivative of the function f(x) at x = 0 is ƒ'(0) = 1. The derivative of a polynomial function is given by ƒ'(x) = 2x + ax + bx^2 - 1. Plugging in x = 0, we get ƒ'(0) = 20 + a0 + (-1)*0^2 - 1 = 1. Solving for a, we get a = 1.
Therefore, the values of a and b are a = 1 and b = -1. The sum of these values is a + b = 1 + (-1) = 0.
