Charge per day = $90 / 15 = $ 6
<span>Charge per year = $ 6 * 365 1/4 ( If the year contains 365 1/4 days) </span>
<span>= $ 2191.5 </span>
<span>As a percentage = 2191.5 / 1460 * 100 = 150 %
So the answer should be 150%</span>
Answer: x^2 + y^2 -10y = 0
Step-by-step explanation:
Cartesian coordinates, also called the Rectangular coordinates, isdefined in terms of x and y. So, for the problem θ has to be eliminated or converted using basic foundations that are described by the unit circle and the right triangle trigonometry.
r= 10sin(θ)
Remember that:
x= r × cos(θ)
y= r × sin(θ)
r^2= x^2 + y^2
Multiply both sides of the equation by r. This will give:
r × r = 10r × sin(θ)
r^2 = 10r × sin(θ)
x^2 + y^2= 10r × sin(θ)
Because y= r × sin(θ), we can make a substitution. This will be:
x^2 + y^2= 10y
x^2 + y^2 -10y = 0
The above equation is the Rectangular coordinate equivalent to the given equation.
Answer:
7
Step-by-step explanation:
2 x (3-1) + 3
Evaluate using PEMDAS
Parenthesis
Exponents
Math and Division ( left to right )
Addition and Subtraction ( left to right )
2 x (3-1) + 3
According to PEMDAS we do the operations inside of the parenthesis first
3 - 1 = 2
We now have: 2 x 2 + 3
Next we do exponents
There are no exponents so let's move on to multiplication and division
There is indeed multiplication so we do it
2 x 2 = 4
We now have: 4 + 3
Finally we do the addition
4 + 3 = 7
The answer is 7
