Step-by-step explanation:

the question is z²=1

taking square root on both sides

√z² = √1

the square root and the square cancel out each other

it gives

z=±1

that means either z=+1 or z=-1

so the solutions are 1 and -1

What steps would you use to plot (−3, −4, 0) in a 3-dimensional coordinate system?
eimsori [14]

Answer:

a. From the origin, move back 3 units and down 4 units

Step-by-step explanation:

Given:

The coordinates of a point in a 3-dimensional space is given as:

(-3, -4, 0)

The value of 'x' = -3

The value of 'y' = -4

The value of 'z' = 0

At the origin, the values of 'x', 'y', and 'z' are each equal to 0.

So, the coordinates of origin is (0, 0, 0). In order to reach the point (-3, -4, 0) from the point (0, 0, 0), we don't move along the z-axis as the 'z' value remains the same. We need to move along the 'x' and 'y' directions only.

Now, 'x' is equal to -3. Negative values of 'x' occur backwards from origin. So, we move back by 3 units. to reach the point (-3, 0).

Now, the value of 'y' is -4. Negative values of 'y' occur below the origin. So, we move down by 4 units to reach the point (-3, -4).

Therefore, the correct option is option (a)

A graph in 2 dimensional is shown in support of the answer.

The moon is about 240,000 miles from Earth. What is the distance written as a whole number multiplied by a power of ten?
spin [16.1K]

The answer is 24 * 10^4

Since we’re asked for a whole number, we count the number of zeros after the first nonzero numbers. In this case, our first non-zero numbers are 2 and 4 (24). The number of zeros after these numbers  are four (4). The number of zeros indicates the power number of 10.

Had we been asked for a decimal number   and a power of 10, then the answer  would have been 2.4 * 10^5
