Hi there!
Using the formula - n-2*180 -, we know that the interior angles of a pentagon add up to 540. We can use the values we're given and add them together and set them all equal to 540, then solve.
WORK:
540 = 204 + 12x
336 = 12x
x = 28
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
no i don't think so the answer will be (3,0)
Answer:
4 coins
Step-by-step explanation:
First, let's find out how much she gave the teller:
2($20)=$40
Now, let's find out how much change the teller owes her:
$40.00-$39.63=$0.37 or 37 cents
The largest coin (under 37 cents), is a quarter which is worth 25 cents...
37-25=12 cents
The largest coin (under 12 cents), is a dime which is worth 10 cents...
12-10=2
The largest coin (under 2 cents), is a penny which is worth 1 cent...
2-1=1
And one more penny...
1-1=0
Therefore the fewest amount of coins she can get in change are a quarter, a dime, and two pennies, which is 4 coins.
Given the equation:
Let's identify the type of polar graph for the equation.
To identify the type of polar graph, use the formula below to get the Cartesian form:
Thus, we have:
![(x^2+y^2)=3\sqrt[]{x^2+y^2}-5x](https://tex.z-dn.net/?f=%28x%5E2%2By%5E2%29%3D3%5Csqrt%5B%5D%7Bx%5E2%2By%5E2%7D-5x)
We have the graph of the equation below:
We can see the graph forms a Limacon with an inner loop.
Therefore, the type of polar graph for the given equation is a limacon with inner loop.
