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:
51.08 in.²
Step-by-step explanation:
S.A = (l x b) + (l × h) + (b × h)
= (8.2 in. × 3.4 in.) + (8.2 in. × 2 in.) + (3.4 in. × 2 in.)
= 27.88 in.² + 16.4 in.² + 6.8 in.²
= 51.08 in.²
The answer is 5 to this expression
