The graph shows the speed of a vehicle during the final 50 seconds of a journey. At the start of the 50 seconds the speed is k metres per second.
The distance travelled during the 50 seconds is 1.7 kilometres.
b) Work out the value of k.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:
