Mathematics
1 answer:
bagirrra123 [75]3 years ago
3 0

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

• 1 + cot² x = csc²x and csc x = \frac{1}{sinx}

• sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x

Consider the left side

sin²Θ( 1 + cot²Θ )

= sin²Θ × csc²Θ

= sin²Θ × 1 / sin²Θ = 1 = right side ⇔ verified

-----------------------------------------------------------------

Consider the left side

cos²Θ - sin²Θ

= cos²Θ - (1 - cos²Θ)

= cos²Θ - 1 + cos²Θ

= 2cos²Θ - 1 = right side ⇒ verified

What numbers would you multiply -3/4 by to equal 1?
Sonja [21]
You would multiply by -4/3. That's cuz to get to 1, you have to cancel out the negative, with another negative. You then have to multiply by the reciprocal. 

Hope this helps!

Step-by-step explanation:

0.25 x 63 = 15.75

0.05 x 63 = 3.15

----------------------------

0.25 x 50 = 12.50

                    +         = $13.15

0.05 x 13 = 0.65

----------------------------

0.25 x 25 = 6.25

                   +        = $8.15

0.05 x 38 = 1.90

----------------------------

0.25 x 30 = 7.50

                   +         = $9.15

0.05 x 33 = 1.65

--------------------------

0.25 x 35 = 8.75

                   +        = $10.15

0.05 x 28 = 1.40

-------------------------

0.25 x 38 = 9.50

                   +        = $10.75

0.05 x 25 = 1.25

------------------------------

I hope this helps!
