Answer:
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
one of the sides that has angle measure 45 is given as 4
to find the length of BC we we need to multiply 4 with
4 * = 4
The volume in cubic cm, is 108 cm cubed (or to the 3rd power). The formula used to find the volume is Length times Width times height.
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).
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
