Miguel has a total of 27 dimes and nickels. The total value of the coins is $1.80. How many dimes and nickels does he have?

soldi70 [24.7K]

Answer:

There are 9 dimes and 18 nickels.

Step-by-step explanation:

Let d = be the number of dimes

n = be the number of nickels

d + n = 27...eq.1

0.10d + 0.05n = 1.80...eq.2

Solve the system of equations

d + n = 27

10d + 5n = 180 ( multiply eq.2 by 100 )

-5d - 5n = -135

5d = 45

d = 9 , there are 9 dimes so,0.90

n = 27 - 9 = 18, there are 18 nickels so, 0.90

To check: 9 dimes + 18 nickels = 27 coins

0.90 + 0.90 = $ 1.80 total value of the coins

Integration of (cosec^2 x-2005)÷cos^2005 x dx is

kondor19780726 [428]

We are asked in the problem to evaluate the integral of (cosec^2 x-2005)÷cos^2005 x dx. The function is an example of a complex function with a degree that is greater than one and that uses special rules to integrate the function via the trigonometric functions. For example, we integrate
2005/cos^2005x dx which is equal to 2005 sec^2005 x since sec is the inverse of cos. The integral of this function when n >3 is equal to I=∫sec(n−2)xdx+∫tanxsec(n−3)x(secxtanx)dx
Then,
∫tanxsec(n−3)x(secxtanx)dx=tanxsec(n−2)x/(n−2)−1/(n−2)I
we can then integrate the function by substituting n by 3.

On the first term csc^2 2005x / cos^2005 x we can use the trigonometric identity csc^2 x = 1 + cot^2 x to simplify the terms
