Answer:

Step-by-step explanation:

Given that vector a has starting point (2,3) and end point (5,7)

Direction ratios of AB = (5-2, 7-3) = (3,4)

Magnitude = \sqrt{3^2+4^2} =5

a) Starting point (0,2)

Distance= 5 units from (0,2) and direction ratios (3,4)

So the point will be of them (0+3t, 2+4t)

Distance = 5t units.  So t =1

So point is (3,6)

b) When starting point =(0,5)

End point with same direction would be

(0+3, 5+4) = (3,9)

Say you wanted to give someone 35000 berries, but every time you give someone berries, it takes away 30%. How could you calculat
VladimirAG [237]

Answer:

What I understand is that I need to give someone an exact number so that when 30% is taken, they keep exactly 35,000

To make the statement above true, we would need to divide 35,000 by 7 since the answer would be 10% of the number we need. Once we do this we get 5000 which is 10% now we multiply 5000 by 10 to get 100% and we get 50.000 once we give this amount to the person and 30% is taken away they are left with 35,000
