What is the value of i^n if the remainder of n/4 is 2?

nydimaria [60]

Answer:

C and D

Step-by-step explanation:

i=√-1

n/4=x.5

since 2 is the remainder

n=2x

then i^n=i^2x

when x is even, i^n =1

when x is odd, i^n=-1

The graph of a linear relation passes through the point (-2,7) and has a slope of 1/6.

docker41 [41]

Answer:

Step-by-step explanation:

eq. of any line withslope 1/6 is

y=1/6x+c

∵ it passes through (-2,7)

so 7=1/6(-2)+c

c=7+1/3=22/3

eq. of line is

y=1/6x+22/3

At the end of each week, an employer gives some vacation hours to a few randomly selected employees. There are 25 employees in h

densk [106]

Answer: There are 177100 possible groups.

Step-by-step explanation:

Given: Total employees = 25

Number of employees wants to choose = 6

The combination of n things taken r at a time is given by:-

$^nC_r=\frac{n!}{r!(n-r)!}$

Put n = 25 and r= 6, we get

$^{25}C_6=\frac{25!}{6!(25-6)!}\\\\=\frac{25\times24\times23\times22\times21\times20\times19!}{6!19!}\\\\=177100$

Hence, there are 177100 possible groups.

Hurry 50 points for correct answer

Ad libitum [116K]

Answer: <em>"7 is a solution to the original equation. The value –1 is an extraneous solution."</em>

Step-by-step explanation:

The equation $x=\sqrt{6x+7}$ can be solved by squaring both sides:

$x^2 = 6x + 7\\\\x^2 - 6x - 7 = 0\\\\(x-7)(x+1) = 0$

We can see that -1 and 7 are solutions, but make sure they are not extraneous by substituting them in the original equation:

$1 = \sqrt{-1}\\ 7 = \sqrt{49}$

The square root of 49 equals 7, but the square root of -1 is an imaginary number.

The correct choice is <em>"7 is a solution to the original equation. The value –1 is an extraneous solution."</em>
