PLEASE HELP Trig Idenities

kari74 [83]

$\dfrac{\sin(A+B)}{\sin(A-B)}=\dfrac{\sin A\cos B+\cos A\sin B}{\sin A\cos B-\cos A\sin B}$

Divide through all terms by $\cos A\cos B$ . Then, for instance, the first term in the numerator becomes

$\dfrac{\sin A\cos B}{\cos A\cos B}=\dfrac{\sin A}{\cos A}=\tan A$

All other terms reduce similarly, giving the final product

$\dfrac{\tan A+\tan B}{\tan A-\tan B}$

Which continent is estimated to have more than 5.31 billion people by 2050? To solve find what percent 5.31 is of billion is of

emmasim [6.3K]

The continent which has 59% of the total population will have more than 5.31 billion people by 2050.

Step-by-step explanation:

It is given that,

The total number of people is 9 billion.
The estimated number of people in 2050 year is 5.31 billion.

Therefore, you need to find out which continent has the estimated number by finding the percentage value.

To find what percent 5.31 is of billion is of 9 billion :

Let x be the percentage to be calculated.

⇒ x percent of 9 billion is 5.31 billion.

⇒ (x/100) × 9 = 5.31

⇒ x = (5.31 × 100) / 9

⇒ x = 531 / 9

⇒ x = 59 %

∴ The continent which has 59% of the total population will have more than 5.31 billion people by 2050.

9(k-4)-7k=32-2(k-8)

IrinaK [193]

Answer: k=21

Step-by-step explanation:

1. Distribute the 9 to the k and the -4 in the parentheses.

9 · k = 9k and 9 · -4 = -36

You now have 9k - 36 - 7k. You can combine the like terms of 9k and -7k and get 2k, giving you 2k - 36.

2. For the other side of the equation, you also distribute -2 to the k and -8 in the parantheses.

-2 · k = -2k and -2 · -8 = 16

You now have 32 - 2k + 16. Combine the like terms 32 and 16 (32 + 16) and you get 48. This gives you the equation 48 - 2k.

3. Now you should have the equation 2k - 36 = 48 - 2k.

You want the k on one side of the equation so you need to cancel out one of them. I cancelled out -2k by adding 2k to it. You also need to add this 2k to your 2k on the other side of the equation.

Ex: 2k - 36 = 48 - 2k

+2k +2k

4. Now you should have 4k - 36 = 48. You need to get 4k by itself so cancel out -36 from both sides by adding 36 to -36 and adding 36 to 48.

You should now have 4k = 84 (48 + 36 = 84).

Divide both sides by 4 to get k by itself. 4 divided by 4 makes k and 84 divided by 4 equals 21. This makes k = 21, which is your answer.
