whats the rest? :)
Step-by-step explanation:
Answer:
(x-2)²+(y+3)²=9
Step-by-step explanation:
We know that the formula for the area of the circle is:
(x-h)²+(y-k)²=r²
-h,k being the center coordinates
-r being the radius
In this case, (2,-3) are the center coordinates and 3 the radius, so simply plug these into the equation giving us:
(x-2)²+(y+3)²=9
Answer:
We also know that for Wedneday we have two times tickets for adults compared to child so we have
And using this condition we have:
And solving for X we got:
So then the number of tickets sold for child are 36
Step-by-step explanation:
For this problem we can set upt the following notation
X = number of tickets for child
Y= number of tickets for adults
And we know that the total revenue for Wednesday was 831.60. So then we can set up the following equation for the total revenue
We also know that for Wedneday we have two times tickets for adults compared to child so we have
And using this condition we have:
And solving for X we got:
So then the number of tickets sold for child are 36
It would be 7.68 because you divided
