<u>Step-by-step explanation:</u>
Use the formula y = A cos (Bx - C) + D where
- A = amplitude
- Period = 2π/B
- Phase Shift = C/B
- D = vertical shift (aka midline)
Given: Max = 8, Min = 2, (1/2)Period = 20 → Period = 40
Amplitude (A) = (Max - Min)/2
= (8 - 2)/2
= 6/2
= 3
Midline (D) = (Max + Min)/2
= (8 + 2)/2
= 10/2
= 5
Period = 2π/B
→ B = 2π/Period
= 2π/40
= π/20
Notice that the Minimum touches the y-axis (not the Max) so there is no phase shift but there is a reflection → C-value = 0 & A-value is negative
Now, let's put it all together:
A = -3, B = π/20, C = 0, D = 5

20 x 5 = 100 so just 18 x 5 = 90. 100 - 90= 10
the answer is 10%
Answer:
64??? take it with a grain of salt but i think its 64
Step-by-step explanation:
There are 6 sides to a die and if its rolled twice thats 12 possible answers and then a standard deck has 52 cards so thats 12+52=64
If it is including herself then Kali would've started with 17 pieces of candy. But if it isn't herself then she would've started with 10 pieces of candy. Hope that helps.
