HELP WILL GIVE BRAINLIEST FOR ANSWER QUICKLY PLEASE HELP

Mathematics
1 answer:
Helen [10]3 years ago
5 0

Answer:

We have sinθ = 12/13

The  method here is to figure out the value of θ

Using a calculator sin^(-1)(12/13) =67.38°

67.38° is in quadrant 1  so we must substract 67.38° from 180° wich is π

  • 180-67.38= 112.61° ⇒ θ= 112.61°

Now time to calculate cos2θ and cosθ using a calculator

  • cosθ = -5/13
  • cos2θ =  -0.7

The values we got make sense since θ is in quadrant 2 and 2θ in quadrant 3

kiruha [24]

Answer:

option B

3

Step-by-step explanation:

Given in the question an expression

\sqrt\frac{48}{x}

Whole numbers are positive numbers, including zero, without any decimal or fractional parts.

Possible range of domain will be 1 ≤ x ≤ 48

We know that perfect square between 1 and 48 are

1 , 4 , 16 , 25 , 36

1)

x = 3

√48/3 = √16 = 4

2)

x = 12

√48/12 = √4 = 2

3)

x = 48

√48/48 = √1 = 1

-6n + (-12) + 4n = -6n  + 4n - 12 = -2n - 12

-2n - 12 is your answer
