Solve the problem.
Lorico [155]

Answer:

<h2>560</h2>

Step-by-step explanation:

You must use a combination:

_nC_k=\dfrac{n!}{k!(n-k)!}

We have <em>n = 16</em>, <em>k = 3</em>.

Substitute:

_{16}C_3=\dfrac{16!}{3!(16-3)!}=\dfrac{13!\cdot14\cdot15\cdot16}{2\cdot3\cdot13!}\qquad\text{cancel}\ 13!\\\\=\dfrac{14\cdot15\cdot16}{2\cdot3}=\dfrac{7\cdot5\cdot16}{1}=560

If f(x) = x2 – 3x – 40 intersects the x-axis at points A and B, what is the sum of A and B?
Eduardwww [97]

Answer:

3

Step-by-step explanation:

Intersections on the x axis occur when y = 0. f(x) is another term for y, so set f(x) equal to zero and solve for the two possible x's.

0 = x^2 - 3x - 40

0 = (x-8)(x+5)

By solving for x, you get 8 and -5. 8 and -5 added together will equal 3.
