Im not sure wym but i think the answer is 20
Answer:
y=2x-19
Step-by-step explanation:
I'm guessing you mean slope intercept form y=mx+b
If so, first you would have to find the slope of the line
To do that, use the formula y2-y1/x2-x1
Remember you can pick any coordinate pair for this
I will pick 1=y2 -5=y1 10=x2 and 7=x1
When I put that in the equation I get 1-(-5)/10-7
Overall I get 6/3, or 2
Now to find the y intercept, you plug in the slope and one of the coordinates(any is fine)
I will pick (10,1)
1=y and 10=x and 2=m
1=2(10)+b
this simplifies to 1=20+b
now subtract 20 from both sides and get -19 = b
Now you have your equation y=2x-19
The cross section would be a semicircle because a cross section of the whole thing would be a circle
Hope this helps
<h3>Answer: Step-by-step explanation:
You have to make an addition with the individual times: 56.25+59.89+58.55+55.4=230.17 seconds. Now you should to convert it into a minutes and seconds. 1 minute= 60 seconds
2 minute= 120 seconds
3minute= 180 seconds
4minute= 240 seconds
In this way you they have 3 minutes and the remainder is 50 seconds.
So, the time for the team is 3 minutes and 50.17 seconds.</h3>
