Step-by-step explanation:

(sin(2n) − 1) / (sin n − cos n)

-(1 − sin(2n)) / (sin n − cos n)

-(1 − 2 sin n cos n) / (sin n − cos n)

-(sin² n − 2 sin n cos n + cos² n) / (sin n − cos n)

-(sin n − cos n)² / (sin n − cos n)

-(sin n − cos n)

cos n − sin n

Limit as n approaches π/4 is 0.

Harrison has $9.30 in his coin collection all in pennies and dimes the number of dimes is three times the number of pennies how
Vsevolod [243]

Answer:

Number of Pennies = 30

Number of Dimes = 90

Step-by-step explanation:

Let the number of pennies be p and number of dimes be d

We can write 2 equations and use substitution method to solve.

<u>Total value of all the coins is 9.30:</u>

We can write:

0.01p + 0.1d = 9.30

Note: value of penny is 0.01 and dime is 0.1, in dollars

<u>Number of dimes is 3 times number of pennies:</u>

We can write:

d = 3p

Now putting 2nd equation in first and solving for p:

0.01p + 0.1(3p) = 9.30

0.01p + 0.3p = 9.30

0.31 p = 9.30

p = 9.30 /0.31

p = 30

Now we know d = 3p, so d = 3 (30) = 90

Hence

Number of Pennies = 30

Number of Dimes = 90
