Answer:
The first three nonzero terms in the Maclaurin series is
Step-by-step explanation:
GIven that:
The Maclaurin series of cos x can be expressed as :
From equation(1), substituting x with (4x), Then:
The first three terms of cos (4x) is:
Multiplying equation (2) with (3); we have :
Finally , multiplying 5 with ; we have:
The first three nonzero terms in the Maclaurin series is
10% of 20 is half of 20% of 20
Answer:
The cost of 1 videotape = $ 3.4
Step-by-step explanation:
Let us assume the cost of each cassette tap = $ m
So, the cost of each videotape = 2 x ( Cost of 1 cassette) = 2 x m = 2 m
Now, the cost of 3 cassette tap = 3 x ( Cost of 1 cassette) = 3 x m = 3 m
Also, the cost of 5 videotape = 5 x ( Cost of 5 videotape) = 5 x (2m) = 10 m
So, the cost of 3 cassette tap + 5 videotape = 3 m + 10 m
Also, given 3 blank cassette tapes and 5 blank videotapes costs $22.10 .
⇒ 3 m + 10 m = $22.10
or, 13 m = 22.10
⇒ m = 22.10/13 =1.7
or, m = $1.7
Hence, the cost of 1 cassette = m = $1.7
And, the cost of 1 videotape = 2 m = 2x ($1.7) = $ 3.4
