Step-by-step explanation:
First thing I would do is square the 14, and put it under the radical. Itll make the calculations a little bit easier.
14sqrt(2) = sqrt392
Use the definition of sine to find the value of a
sin(45) = opposite/hypotenuse = a/sqrt392
a = 14
Answer:
i believe the answer is 1
Step-by-step explanation:
Assuming that the expression equals 0
3x+9=0

3x= -9
-9/3= -3
x= -3
I'm not sure if this is correct because of the amount of information given but I think it might 9m.... If you still need help and want to explain it differently I will gladly help!
The total distance covered by Mary is 6miles
total time spent is 2 and half hours
average speed is given by,total distance divided by total time
so,6/2.5=2.4miles per hour
