Answer:−√33/7


Step-by-step explanation:

Second quadrant implies cos negative, as cos is projection from

unit circle to x axis.

sin^2+cos^2=1

cos= sqrt(1-sin^2)

sin^2 = 16/49

1-sin^2 = 33/49

sin= -sqrt(33)/7

F(x)=16^X<br> 1. F(x)=4 x/4<br> 2.f(x)=2^4x<br> 3. F(x)=2 x/4<br> 4. F(x)=4^4x
kicyunya [14]

Answer:

2.f(x)=2^4x

Step-by-step explanation:

16^x

We can rewrite 16 as 2^4

2^4^x

We know that a^b^c is equal to a^ (b*c)

so 2^(4*x)

2^(4x)
