Answer:
The car must have a speed of 25 kilometres per hour to stop after moving 7 metres.
Step-by-step explanation:
Let be 
, where 
is the stopping distance measured in metres and 
is the speed measured in kilometres per hour. The second-order polynomial is drawn with the help of a graphing tool and whose outcome is presented below as attachment.
The procedure to find the speed related to the given stopping distance is described below:
1) Construct the graph of 
.
2) Add the function 
.
3) The point of intersection between both curves contains the speed related to given stopping distance.
In consequence, the car must have a speed of 25 kilometres per hour to stop after moving 7 metres.
Answer:
A parallel line is something that is equivalent on the other end. This mean if you cut a shape, a square for example, in half,the sides will be of equal length.
32x^3+4x^2+41x-35
hope it helps
Answer:
A
Step-by-step explanation:
Look at the graph of the relationship. Find the y-value of the point that corresponds to x = 1. That value is the unit rate
The value that could me added to 2/5 that could make the sum greater than 1/2 is 1/5 possibly. Hope this helps! :)
