If cos theta = -4/7 what are the values of sin theta and tan theta?

1 answer:

4 0

cosθ = ⁻⁴/₇
cos⁻¹(cosθ) = cos⁻¹(⁻⁴/₇)
θ = 124.8499046

sinθ = sin(124.8499046) = 0.820651806
tanθ = tan(124.8499046) = -1.436140661

Answer:

The answer to your question is the first option

Step-by-step explanation:

64 $^{1/4}$

Process

1.- Find the prime factors of 64

64 2

32 2

16 2

8 2

4 2

2 2

64 = 2⁶

2.- Express 64 as a fractional exponent

64 $^{1/4} = 2^{6/4}$

3.- Simplify

64 $^{1/4} = 2^{4/4} 2^{2/4}$

64 $^{1/4} = 2^{1} 2^{2/4}$

64 $^{1/4} = 2\sqrt[4]{2^{2}}$

4.- Result

64 $^{1/4} = 2\sqrt[4]{4}$
