Ghella [55]

Answer:

The number of ways are 40320.

Step-by-step explanation:

Consider the provided information.

Ms. Smith keeps eight different cookbooks on a shelf in one of her kitchen cabinets.

We need to determine the number of different ways to put eight cookbooks on the shelf.

We need to select 8 cookbooks taking 8 at a time.

So use the permutation formula: $^{n}P_{n}$

Substitute n=8 and simplify.

$^8P_8=\frac{8!}{(8-8)!}\\8!=40320$

Hence, the number of ways are 40320.

Given cosx= 4/5 when (3π/2) < x<2π find sin2x

jarptica [38.1K]

Answer:

D -24/25

Step-by-step explanation:

sin(2x) = 2sin(x)cos(x)

cos(x) = ⅘

sin²(x) = 1 - cos²(x) = 1 - (⅘)²

sin²(x) = 9/25

sin(x) = -⅗

(Because 4th quadrant)

sin(2x) = 2(-⅗)(⅘)

= -24/25
