For what value of theta does sin 2theta = cos(theta+30)?<br> Show steps

kolbaska11 [484]

Answer: Ф = 20

Step-by-step explanation:

sin2Ф = cos (Ф+ 30 )

if sinα = cosβ , then α and β are complementary ,that is they add up to be $90^{0}$ .

Therefore : 2Ф + Ф + 30 = 90

3Ф + 30 = 90

3Ф = 90 - 30

3Ф = 60

Ф = 20

Factor −1/4 out of −1/2x−5/4y..ㅤ

hammer [34]

Answer:

- 1/4 (2x + 5y)

Step-by-step explanation:

Divide each term by - 1/4 first

-1/2x ÷ (- 1/4) = 1/2x × 4 = 2x
-5/4y ÷ (- 1/4) = 5/4y × 4 = 5y

Now facor out - 1/4

- 1/2x - 5/4y =
- 1/4 (2x + 5y)

Perform the indicated operation. 10 3/7 + 19 5/9

DanielleElmas [232]

Given expression is

$10 \frac{3}{7} + 19 \frac{5}{9}$

Now convert mixed fraction as improper fraction as

$10 \frac{3}{7} + 19 \frac{5}{9} = \frac{10*7 + 3}{7} + \frac{19*9+5}{9}$
                                                         $= \frac{73}{7} + \frac{176}{9}$
                                                          $= \frac{73*9 + 176 * 7}{63}$
                                                         $= \frac{657 + 1232}{63} = \frac{1889}{63}$
Now we can convert $\frac{1889}{63 } = 29 \frac{62}{63}$

So the answer is $29 \frac{62}63}$

Use a form of the distributive property to rewrite the given algebraic expression without parentheses. 2(3x-3)

guajiro [1.7K]

Answer:

6x-6

Step-by-step explanation:

The Distributive property says that a(b+c) = ab+ac

In my example you distribute the value on the outside to the things on the inside

In your problem you have a two on the outside that needs to be distributed to a 3x and a -3

1) 2 multiplied by 3x equals 6x giving you the first part of your answer!

2) 2 multiplied by -3 equals -6 giving you the second part of your answer!

Don't forget that there is a - sign between the 3x and 3, don't drop it!

Put the two values together to get 6x-6

Let me know if you have any further questions :)
