Answer:
(the relation you wrote is not correct, there may be something missing, so I will simplify the initial expression)
Here we have the equation:
We can rewrite this as:
Now we can add and subtract cos^2(x)*sin^2(x) to get:
We can complete squares to get:
and we know that:
cos^2(x) + sin^2(x) = 1
then:
This is the closest expression to what you wrote.
We also know that:
sin(x)*cos(x) = (1/2)*sin(2*x)
If we replace that, we get:
Then the simplification is:
Answer:
Tax is C 4.12
Tip is E 15.00
total =94.10
Step-by-step explanation:
Tax = bill * tax rate
= 74.98 * 5.5%
= 74.98 * .055
= 4.1239
To the nearest cent = 4.12
Tip = bill * tip rate
= 74.98 * 20%
= 74.98 *.2
= 14.996
To the nearest cent = 15.00
The total bill is
Final = bill + tax+ tip
= 74.98 + 4.12+15
= 94.10
Answer:
c < -1
Step-by-step explanation:
There is an open circle at -1 That means it is not equal to
The line goes to the left
That means less than
c < -1
