Write the expression 2i^15-i^7 in the standard form a + bi

elixir [45]

$\bf 2i^{15}-i^7\qquad 
\begin{cases}
i^2=\sqrt{-1}\cdot \sqrt{-1}\implies \sqrt{(-1)^2}\implies -1\\\\
i^4=i^2\cdot i^2\implies -1\cdot -1\implies 1
\end{cases}\\\\
-----------------------------\\\\
2i^{4+4+4+2+1}-i^{4+2+1}\implies 2i^4i^4i^4i^2i^1-i^4i^2i^1
\\\\\\
(2\cdot 1\cdot 1\cdot 1\cdot -1\cdot i)-(1\cdot -1\cdot i)\implies -2i-(-i)
\\\\\\
-2i+i\implies -i\implies \boxed{0-i}$

Here are ten numbers

ser-zykov [4K]

Solution,

Given data=3, 7 , 2 , 4, 7, 5, 7, 1, 8, 8

a.Mode= 7 because it has more frequency in comparison to others.

b.Arranging the data in ascending order:

: 1,2,3,4,5,7,7,7,8,8

N(total number of items)=10

Median=(N+1/2)th item

 = (10+1/2)th item

 = (11/2)th item

 = 5.5th item

Again,

5th item+6th item/2

 = 5+7/2

=12/2

= 6

c. summation FX=52

 N=10

Mean= summationfx/N

 =52/10

 =5.2

D. Range= highest score- lowest score

 = 8-1

 =7

Hope it helps

Good luck on your assignment

If the endpoints of AB are at (-4, 5) and (2, -7), what is the length of AB?

Sonbull [250]

Answer:

The length of AB is $6\sqrt{5}$ units

Step-by-step explanation:

The rule of the distance between two points (x1, y1) and (x2, y2) is

$d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}$

∵ The endpoints of AB are (-4, 5) and (2, -7)

→ Let point (-4, 5) be (x1, y1) and point (2, -7) be (x2, y2)

∴ x1 = -4 and y1 = 5

∴ x2 = 2 and y2 = -7

→ Substitute them in the rule above to find the length of AB

∵ $AB=\sqrt{(2--4)^{2}+(-7-5)^{2} }=\sqrt{(2+4)^{2}+(-12)^{2}}$

∴ $AB=\sqrt{(6)^{2}+144}=\sqrt{36+144}$

∴ $AB=\sqrt{180}=6\sqrt{5}$

∴ The length of AB is $6\sqrt{5}$ units
