Sin(x-y) if cos x =8/17 and cos y = 3/5

Dima020 [189]

$\sin(x-y)=\sin x\cos y-\sin y\cos x$

Since $\cos x=\dfrac8{17}$ , you have

$\sin x=\sqrt{1-\cos^2x}=\sqrt{1-\left(\dfrac8{17}\right)^2}=\dfrac{15}{17}$

and since $\cos y=\dfrac35$ , you have

$\sin y=\sqrt{1-\cos^2y}=\sqrt{1-\left(\dfrac35\right)^2}=\dfrac45$

So,

$\sin(x-y)=\dfrac{15}{17}\times\dfrac35-\dfrac45\times\dfrac8{17}=\dfrac{13}{85}$

Note that this assumes that both $\sin x$ and $\sin y$ are positive, or $0$ .

The percent of pure gold in 14-karat gold is about 58.3%. A 14-karat gold ring weighs 5.6 grams. About how many grams of pure go

lubasha [3.4K]

Answer:

1.044 ounces

Step-by-step explanation:

Given : One ounce of 14 karat gold = 0.58 ounce of pure gold.

i.e. Weight of pure gold in 1 ounce of 14 karat gold = 0.58 ounce of pure gold.

Then, Weight of pure gold in 1.8 ounces of 14 karat gold = 1.8 x (Weight of pure gold in 1 ounce of 14 karat gold)

Weight of pure gold in 1.8 ounces of 14 karat gold = 1.8 x ( 0.58) ounces of pure gold.

It implies 1.8 ounces of 14 karat gold = 1.8 x ( 0.58) ounces of pure gold.

= 1.044 ounces of pure gold.

Therefore, If a 14 karat gold necklace weighs 1.8 ounces that means it contains 1.044 ounces of pure gold.
