Answer: 10x³

Step-by-step explanation:

n=0 1

n=1 1 2 1

n=2 1 3 3 1

n=3 1 4 6 4 1

n=4 1 5 10 10 5 1

The second term of the expansion is: 5(a)³(b)

= 5(x)³(2)

= 10x³

Which angle is an x-intercept for the function y = cos(1) A.0 B.2 C. £ D. 2£

noname [10]

Answer: C. $\pi$

=======================================================

Explanation:

The x intercept always occurs when y = 0.

Use the unit circle to determine that $\cos(\theta) = 0$ when $\theta = \frac{\pi}{2} \text{ and } \theta = \frac{3\pi}{2}$

So if $x = \pi$ , then we have

$y = \cos\left(\frac{1}{2}x\right)\\\\y = \cos\left(\frac{x}{2}\right)\\\\y = \cos\left(\frac{\pi}{2}\right)\\\\y = 0\\\\$

which shows us that $(\pi, 0)$ is the location of one of the infinitely many x intercepts for this function.
