Given :
We know the identity
We use this property to simplify the left hand side
So
we know ,
when then
For
Add on both sides
Finally we add 2npi for general solution
So options C and D are correct
1.8 TIMES 3 = 5.4. Therefore, the new price is 12.6.
Answer:
Third option <3, 9>
Step-by-step explanation:
u and v are two vectors and we know the Cartesian components of these vectors.
We must find the sum of u + v.
If we have the Cartesian components of both vectors then the sum of both is done by adding the components of u with the components of v.
Where i is the vertical component and j is the horizontal component
Then u + v is
So Regina has 120 coins=total
120=total
we will use q=number of quarters and d=number of dimes
120=d+q
she has 10 more dimes than quarters
d=q+10
so if we susitute this into the equation then we get
120=(q+10)+q
add like terms
120=2q+10
subtract 10 from both sides
110=2q
divide both sides by 2
55=q
she has 55 quarters
subtitute into second equation
d=10+55
d=65
dimes=65
quarters=55
