Answer: Choice D
y = cos(x+pi)
============================================
Explanation:
Make sure your calculator is in radian mode.
If we plug x = 0 into each answer choice, we get the following
Choice A: y = cos(x+pi/2) = cos(0+pi/2) = 0
Choice B: y = cos(x+2pi) = cos(0+2pi) = 1
Choice C: y = cos(x+pi/3) = cos(0+pi/3) = 1/2 = 0.5
Choice D: y = cos(x+pi) = cos(0+pi) = -1
Only choice D has x = 0 lead to y = -1.
Therefore (0,-1) is a point on the equation of choice D. The graph shows this visually through the y intercept, where the graph crosses the y axis.
13+13 (because there are two sides of one triangle that both equal 13) then with that answer multiply by 10 (because 10 is the base) and that is the area of one triangle, then multiply the area of one triangle by 2 (because there’s two triangles)
Answer:
Well the fundamental theorem of algebra states that a polynomial raised to a power can only have the same number of roots as the power or an even number of roots fewer than the power.
Step-by-step explanation:
For example, a quadratic polynomial is raised to the power of 2, therefore this polynomial can have 2 roots or 0 roots.
A cubic polynomial, which is raised to the power of 3, can either have 3 or 0 roots
