When the exponent is 0, it will always equal 1.

For example:

$x^0=1$

$3^0=1$

Since you know the values of m and n, substitute/plug it into the equation:

$m^0-n^2$ Plug in 2 into "m" since m = 2, and plug in -1 into "n" since n = -1

$(2)^0-(-1)^2$

1 - (1)

Answer:

Median

Step-by-step explanation:

Center of distribution is the middle of a distribution, much like the median. The median of a set of numbers is the number in the middle. Since these two are pretty similar, median would be the best to describe the centers of distribution out of the terms provided.

Edit: I'm leaning towards B.) Both aren't symmetrical

Help please. ASAP.

Alex

Step-by-step explanation:

We can rearrange line M so it is in y = mx + b form.

2y - 10x + 3 = 0 -> 2y = 10x - 3 -> y = 5x -3/2. Since line L and line M have the same slope (which is the m value, 5), they are parallel.

I hope this helps! :)

2. If ¡2x+3 = i, where i = V-1, then which of the

Alexus [3.1K]

I assume you mean the equation

$i^{2x+3} = i$

Since i = √(-1), we have i⁴ = 1 and so i⁵ = i. Then 2x + 3 must be some multiple of 5.

Now just check for which of the given choices that this holds:

x = 16 ⇒ 2x + 3 = 35 (yes)

x = 11 ⇒ 2x + 3 = 25 (yes)

x = 10 ⇒ 2x + 3 = 23 (no)

x = 14 ⇒ 2x + 3 = 31 (no)

Scorpion4ik [409]

Answer:the expression is 5x - 2

Step-by-step explanation:

The number of customers in a store on the first day is represented by: (6x - 3).

The number of customers on the second day is represented by: (x - 1)

An expression to find how many more customers visited the store on the first day would be the difference between the number of customers that visited the store on the first day and the number of customers that visited the store on the second day. The expression becomes

6x - 3 - (x - 1)

= 6x - 3 - x + 1

= 6x - x - 3 + 1

= 5x - 2
