The center of the clock is taken as the origin.The clock is a circle with a diameter 10 units.Radius is half the diameter .Radius = 10 ÷2= 5 units.

The clock is divided in four quadrants .On x axis y=0 and on y axis x=0.

When it is  12 o'clock the hour hand is on positive of y axis.Coordinates of the point at 12 o'clock=(0,5)

When it is 3 o 'clock the hour hand is on positive of x axis .Coordinate of the point at 3o'clock is (5,0)

When it is 6 o'clock the hour hand is on negative of y axis .The coordinates of the point at 6o'clock is (0,-5)

At 9o'clock the hour hand is on negative of x axis .The coordinate of the point at 6o'clock is(-5,0)

(8+5i) + (10+6i)-(3+6i)
Natali [406]

Answer:

15 + 5i

Step-by-step explanation:

(8+5i) + (10+6i)-(3+6i) \\  \\  = 8 + 5i + 10 + 6i - 3 - 6i \\  \\  =( 8 + 10 - 3 )+ (5i + 6i - 6i )\\  \\  = 15 + 5i

Find the length of the altitude drawn to a side of an equilateral triangle whose perimeter is 30.
enot [183]
To solve this problem, you must find the altitude, represented by a dashed line in this picture.

To do this, use the Pythagorean theorem: a^2 + b^2 = c^2

The hypotenuse (longest side in a triangle) is always the c value. So plug that into your equation for c.
This leaves you with:
a^2 + b^2 = 10^2

Next, plug in your one side length of the triangle that you have besides the hypotenuse, which is a 5. This will be your b value.
This leaves you with:
a^2 + 5^2 = 10^2

After that, square your number values to simplify the equation. To square a number, you multiply it by itself. In this case, 5 x 5 = 25 and 10 x 10 = 100.
So when you rewrite your equation you have:
a^2 + 25 = 100

To start to isolate your variable, subtract 25 on both sides of the equation to keep it balanced.
This results in:
a^2 = 75

To isolate your variable, square root the a variable and square root the other side to keep it balanced. A square root cancels out a square, so that’s how you know you can do this.

Since 75 isn’t a perfect square, find the highest perfect square that’s able to be multiplied to get 75. This is 25. 25 x 3 = 75 so put that under a radical sign.
After that, simplify the radical by taking the perfect square out of the “jail” (square root sign) this causes the perfect square to be square-rooted as it moves across to the other side of the sign. So, your final answer has a five on the outside of the radical sign with a 3 left inside.

So your final answer is:
5 radical sign 3.

How much time do you actually save by speeding?
navik [9.2K]
Is this a genuine question? If so, you would calculate how long it would take for you to reach your destination based on the speed limit. If the speed limit is 40 mph and you need to drive 100 miles, divide the distance by the speed and you find it would take you 2.5 hours. If you speed and go, let’s say 50 mph, divide 100 miles by 50 mph and you will find that it will take 2 hours, saving half an hour of time. Use this strategy to find out how much time you save.
