Answer:
c
Step-by-step explanation:
x²+y²+4x+6y=0
compare with x²+y²+2gx+2fy+c=0
centre is (-g,-f)=(-2,-3)
radius=√(g²+f²-c)=√((-2)²+(-3)²-0)=√13
4(2 + 3) - [7 - [4 - (8 + 5)]]
First, do the parentheses:
4(5) - [7 - [4 - 12]]
Then complete the rest from the inside out:
20 - [7 - (-8)]
20 - 15 = 5
Answer:
1
Step-by-step explanation:
5 *1+48+7*1= 60
12(x+4)=60
Answer:
After 13 minutes have past, there will be a volume of 18.762 L of punch.
Step-by-step explanation:
In this problem, we are asked to find the volume at 13 minutes. We are given this equation...
<em>y = -2.485x + 51.067</em>
We can use this equation to solve our problem. 13 represents our x-value so, we will plug 13 in for x in the equation above.
y = -2.485(13) + 51.067
Multiply -2.485 by 13.
y = -32.305 + 51.067
Now, add the numbers together.
y = 18.762
So, after 13 minutes have past, then the volume of the punch would be 18.762 L.
