Answer:
The common ratio of the sequence is -2.
Step-by-step explanation:
To find the common ratio of a sequence, we divide each term by it's predecessor.
So
-4/2 = 8/-4 = -16/8 = ... = -2
The common ratio of the sequence is -2.
Answer:
x = 3.
Step-by-step explanation:
x = 3 is not linear. By definition a linear function has 2 variables, a dependent and independent variable. This has only x and a constant. It is a linear equation but not a linear function.
You use the tan/cos/sin rules
So we know that the hypotenuse=46.8, opposite=44
We can use sin (negative) to find it
sin^-1=opp/hyp
sin^-1=44/66.8
=70 degrees
Hope this helps!! :)
You can make them have the same denominator and then compare
so as you can see,
