Answer:
(D) an = 5n - 1
Step-by-step explanation:
The sequence is generated by substituting a value for n.
The first term of the sequence is 4
So when n = 1
The formula is an = 5n - 1
a1 = 5(1) - 1
a1 = 5 - 1
a1 = 4
The second term of the sequence is 9.
So n = 2
a2 = 5(2) - 1
a2 = 10 - 1
a2 = 9
To find the next value you just have to substitute the next value for n.
To find median you set up the number least to greasiest and then cross each one out one side at a time until you get to the middle
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
Answer:
40
Step-by-step explanation:
15/6 = x/16 6x=240 divide 240 by 6 to get 40
