For the answer to the question above, I'll provide a solution to my answer below
sin²θ + cos²θ = 1
<span>so, cos²θ = 1 - (5/6)² => 11/36 </span>
<span>=> cosθ = ±√11/6 </span>
<span>Also, tanθ = sinθ/cosθ => (5/6)/(±√11/6) </span>
<span>i.e. tanθ = ±5/√11
</span>I hope my answer helped you. Feel free to ask more questions. Have a nice day!
Answer:
94.5 days
Step-by-step explanation:
We are asked to calculate the time.
The formula to calculate the time for half life =
t = t½ × In (Nt/No)/-In2
t½ = half life = 16 days
No = Initial substance = 120mg
Nt = Amount of substances after time t = 2 mg
t = 16 × In (2/120)/-In2
t = 94.510249529736 days
Approximately = 94.5 days
Therefore, the time it would take for the substance to decay from 120mg to 2 mg is 94.5 days.
Answer:
$588
Step-by-step explanation:
As each shipment has 98 balls, to determine the total cost of playground balls in three shipments, you have to multiply 98 for 3. Then, after determine the amount of balls in the three shipments, you have to multiply that for the price of each ball:
Total amount= 98*3= 294
Total cost= 294*$2= $588
The total cost of playground balls in three shipments is $588.
