I got this answer from someone else so I’m not sure this is correct but I really hope it helps...
Step-by-step explanation:
Look for patterns in the derivatives.
y=cos2x
y'=-2sin2x
y''=-4cos2x
y'''=8sin2x
y''''=16cos2x
Notice that sin and cos alternate every derivative. Also, they alternate positive and negative every 2 derivatives.
The constant is just 2^(derivative#).
Every odd derivative has sin and every even derivative has cos, so you know that the 30th derivative will be cos.
If you follow the pattern of negatives and positives, you find that the 30th derivative will be negative.
y^(30)= -2^30cos2x
y^(30)= -1073741824cos2x
1 hours to fill the dish
for 1/2 of the dish
think
1/2 times 2=2/2=1 so therefor it takes 1 less doubling so
60 mins
1 less double
(double is 6 mins so )
60-6=54
the answe ris 54 mins or a
Answer:
AW=10
Step-by-step explanation:
In a parallelogram opposite sides are congruent meaning XA and AZ are congruent. YA and AW are congruent. So...
Solving for XA and AZ
XA=AZ
3m=5m-4
-2m=-4
m=2
If YW=10m then 10 x 2 = 20
20 divided by 2 = 10
Total number of hours she schduled to play the game = 3
hours.
Let us convert mixed fraction into improper fraction
Duration of each round = 
.
In order to find the number of rounds Nicole can play, we need to divide total number of hours by duration of each round.
÷
Converting division sign into multiplication flips the second fraction.
Crossing out 12 by 4, we get 3 on the top of second fraction.
Because problem is about number of rounds.
So, total number of round would be 5.
