<span>To get my answer, I multiplied
$2075 by 0.3 to get 622.50. Then I subtracted 622.50 from 2075 to get
1452.50.
Hope this helps,

Answer:
Step-by-step explanation:
If I'm interpreting that correctly, you are trying to solve this equation:
for theta. To do this, you will need a trig identity sheet (I'm assuming you got one from class) and a unit circle (ditto on the class thing).
We need to solve for theta. If I look to my trig identities, I will see a double angle one there that says:
We will make that replacement, then we will have everything in terms of sin.
Now get everything on one side of the equals sign to solve for theta:
We can factor out the common sin(theta):
By the Zero Product Property, either
or
Now look at your unit circle and find that the values of theta where the sin is 0 are located at:
The next one we have to solve for theta:
simplifies to
and
Look at the unit circle again to find the values of theta where the sin is -1/2:
Those ar your values of theta!
C.
No value of x has two values of y, thus it is a one-to-one function.
Answer: .
Step-by-step explanation:
Total amount remaining = Initial amount in the card-( Cost per cup × (Number of cups) )
Each cup of coffee costs $1.50 and after buying 4 cups of coffee, the card had a $9 remaining balance.
i.e. 9 = Initial amount in card - (1.50 × 4)
⇒ 9 = Initial amount in card - (6)
⇒ Initial amount in card = 9+-6 =15
⇒ Initial amount in card = $15
Let A be the amount money remaining on the card after buying x cups of coffee.
So, A = 15 - 4x
Hence, the required equation is .
