The pattern that is summed may be written as
S = 1 - 3 + 9 - 27 + . . .
= (-3)^0 + (-3)^1 + (-3)^2 + (3)^3 + . . .
The n-th term in the sum is (-3)^n, for n = 0,1,2,3, . . .
The sum may be written with summation notation as
Answer:
<h2>D. -15/8</h2>
Step-by-step explanation:
Given the following;
cosθ=8/17 and sinθ=−15/17
In trigonometry identity, tanθ = sinθ/cosθ
Substituting the given values in the equation;
tan θ = (−15/17)/(8/17)
tanθ = −15 /17 * 17/8
tanθ = -15/8

First change them all into fractions or decimals. Decimals a probably the easiest.
1/5= 0.2 12/25= 0.48 4/5= 0.8
Order: 0.2, 0.35, 0.48, 0.5, 0.8
Then you change the decimals that you converted back into the fraction form.
Answer: 1/5, 0.35, 12/25, 0.5, 4/5
