Standard Equation for trig function: y = A cos (B (x - H))+ K
*Here, we are just dealing with A (amplitude) and B (period)
Period = 2π/ b
8 = 2π/ b
Solve for b: 2π/8 or π/4
Equation: y = 2 cos (π/4 (x))
The answer is Option B
We know that this inequality doesn't require any negative number division, there's no need to switch the ≤'s into ≥'s.
So now, all we have to do is subtract 25 from every number, giving us <u>5≤x≤50</u>
1.7n +1
I think the is the answer
I hope this helps :)
Hope you could get an idea from here.
Doubt clarification- use comment section.
5x + 6 = 1
Subtract 6 from both sides.
5x = -5
Divide from both sides.
x = -1 (ANSWER)
hope this helps!!
