Answer:

4\sqrt{4}

Step-by-step explanation:

This is an isosceles and right triangle at the same time

In fact, this triangle is called 45-45-90 special right triangle and the side lengths for this special triangle is as follows:

The sides that see the angle with measure 45 is represented with x

and

The side that sees the angle with measure 90 is represented with  x\sqrt{2}

one of the sides that has angle measure 45 is given as 4\sqrt{2}

to find the length of BC we we need to multiply 4\sqrt{2}  with \sqrt{2}

4\sqrt{2} *\sqrt{2} = 4\sqrt{4}

30 points if you can answer this question and tell me how to do it
vlabodo [156]

Answer for a)

Since the coordinates are arranged as (x, y, z), then 3 would be for x, 0 would be for y, and 1 would be for z. The x is the length, the y is the height, and the z is the width. It is said that the x-axis value is 3 so there are 4 letters on the 3 value which are: P, S, B, and A. Now, let's look at the 0 on the y-axis. Since the y-axis is the height, then there are 2 letters remaining: A and B. Now, the z-axis is 1. So the letter for point (3, 0, 1) is... B.

Answer for b)

For the x-axis, P is at 3. For the y-axis, P is at 2. For the z-axis, P is at 1. So the coordinate of P is: (3, 2, 1).

How much time does it take light to travel from the moon to the earth, a distance of 384000?
gulaghasi [49]

V = speed of light = 3 x 108 m/s

d = distance = 384000 x 103 m = 3.84 x 108 m

time taken = t = d/V = 3.84 x 108 /(3 x 108 ) = 1.28 sec
