Step-by-step explanation:
In order to solve this problem we must start by drawing a diagram of what the licence plates look like. (See Attached picture).
Now, each box in the picture will represent one digit of the plate. Some must be numbers and some must be letters. We know we have 9 posibilities for theh numbered boxes (1-9) and we have 26 possibilities for the boxes that are to contain letters. Repetitions allowed. So the possible character for each box is as follows:
box 1 = 1 to 9 = 9
box 2 = A to Z = 26
box 3 = A to Z = 26
box 4 = 1 to 9 = 9
box 5 = 1 to 9 = 9
box 6 = 1 to 9 = 9
box 7 = 1 to 9 = 9
so the total number of licence plates can be found by multiplying the possibilities for each box in the plate so we get:
# of plates = (9)(26)(26)(9)(9)(9)(9)
which can be simplified to:
A ship sails 30.50 mi due East and then turns 33.75 degree north of East. After sailing another 18.53 mi, where is it with reference to the starting point
<u>Answer:</u>
The ship is 18.269 miles distance north of east from starting point
<u>Solution:</u>
Given that ship sails 30.50 miles east
North of east = 18.53 miles
Angle between two sides = 33.75 degree
The figure is attached below
In the figure, A represents starting point
AB = c represents the ship distance with reference to starting point
By using law of cosines,
Ignore negative value as we measure distance in positive
c = 18.269
It is 18.269 miles distance north of east from starting point
