Answer:
see explanation
Step-by-step explanation:
These are the first 4 terms of a geometric sequence with n th term
= a₁ 
where a₁ is the first term and r the common ratio
r = 36 ÷ 24 = 54 ÷ 36 = 81 ÷ 54 = 1.5 and a₁ = 24, hence
= 24 
← explicit formula

Answer:
-8/15
Step-by-step explanation:
So remember what sin, cos, and tan are.
sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent
Now, using what we know of sin and cos, lets find opposite and adjacent to solve for tan.
Sin=-8/17
So this must mean that opposite is -8, and the hypotenuse is 17.
Next, lets find adjacent. Cos = 15/17
So this must mean that adjacent is 15, and again, hypotenuse is 17.
Now lets take the -8 of the opposite, and 15 of the adjacent, and get tan.
<u>Tan: -8/15. </u>
17 is not included in this whatsoever, since hypotenuse is not included in tan. And remember that it cannot be -15/8, since its opposite/adjacent, not adjacent/opposite.
Hope this helps!
Answer:3(x-9) is expressed as 3x-27
Step-by-step explanation: 3(Xminus9)
3(X-9)
Use 3 to open the bracket by using 3 to multiply everything in the bracket.
Then you will get
3x-27
