1/8k + 80 = 1/2k + 120

Step 1: Subtract 1/2k from both sides.

1/8k + 80 - 1/2k = 1/2k + 120 - 1/2k

-3/8k + 80 = 120

Step 2: Subtract 80 from both sides.

-3/8k + 80 - 80 = 120 - 80

-3/8k = 40

Step 3: Multiply both sides by 8/(-3).

(8/-3) x (-3/8k) = (8/-3) x (40)

Answer: k = -320/3 or −106.667

I need help with this questions

SSSSS [86.1K]

Answer:

Picture 1

Your choice C is correct

(x - (-2))² + (y - 9)² = 5² ⇒
(x + 2)² + (y - 9)² = 25

Picture 2

(x + 5)² + (y - 6)² = 36
(x - (-5))² + (y - 6)² = 6²
r = 6, (h, k) = (-5, 6)

Correct choice is C

Picture 3

(x + 5)² + (y + 2)² = 81
(x - (-5))² + (y - (-2))² = 9²
r = 9, (h, k) = (-5, -2)

Correct choice is C

What is the second term in the binomial expansion of (2r-3s)12?

Reptile [31]

$(a+b)^n=\displaystyle\sum_{k=0}^n\binom nka^{n-k}b^k$

where $\dbinom nk=\dfrac{n!}{k!(n-k)!}$ . The second term of the expansion occurs when $k=1$ .

So the second term of the expansion of $(2r-3s)^{12}$ is

$\dbinom{12}1(2r)^{12-1}(-3s)^1=12(2r)^{11}(-3s)=-73728r^{11}s$
