if n < 0
√(n^2) = ???
thank youuuuu

Answers

Answer 1

Answer:

-n

Step-by-step explanation:

The symbol √ means the principal square root.

The principal square root is always non-negative.

For example, even though the number 25 has two square roots, -5 and 5, since both (-5)² and (5)² equal 25, when you express the square root using the square root symbol, then √25 = 5, and not -5, since √25 means the principal square root of 25, and as a principal square root, it must be a non-negative number.

If n < 0, then you are dealing with negative numbers.

Once you square n to get n², n² is a positive number.

Then the square root of n², expressed with the square root symbol as √(n²) must be positive, so it equals -n.

Example:

Let n = -8.

Then n² = (-8)² = 64.

√(64) = 8

Compare 8 to -8. 8 is -(-8), just like we get -n.

Answer: -n

Given that the points (-32,-10) and (-74,11) lie on a line, what is the equation of the line

Answers

The equation of the line with the points (-21, -10) and (-74, 11) is

y = (-/12)x - 26.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

(-32,-10) and (-74,11)

The equation of a line is given as,

y = mx + c

m = (11 + 10) / (-74 + 32)

m = 21 / -42

m = -1/2

Now,

(-32, -10) = (x, y)

-10 = (-1/2)(-32) + c

-10 = 16 + c

c = -10 - 16

c = -26

Now,

The equation of the line is y = (-/12)x - 26.

6.234 x 10^-7

Step-by-step explanation:

When writing the number in standard form you have to look at the decimal point. If you already have a decimal point (like the question) then look for the first non-zero digit (in terms of the question, its 6). You have to move the decimal point to right until its after the first non-zero digit. Count how many spaces you moved, in this case its 7. If you are moving to the left you have to put a negative sign when writing the power of 10.

was available in Andrew's checking account to be transferred to savings after
all the transactions were completed?

Answers

$28.38

1.39 + 512.89= $514.28

3 + 18 + 38 + 100 + 314 = $473

.24 + .30 + .96 + .34 + .78 = $2.62

473 +2.62 = $475.62

514 - 475.62 = $38.38

38.38 - 10 = $28.38
