Name the algebraic property demonstrated in the example below: If x = 3 and 3 = y, then x = y.

NemiM [27]

Its the transitive property. Transitive means that is a=b and b=c then a=c. It matches with what they're asking for.

Please help me please help me the problems are up above

fomenos

The volume of a sphere with radius $r$ is $\frac{4}{3}\pi r^3$ . If the radius is multiplied by a constant $k$ , then the new volume is $\frac{4}{3} \pi (kr)^3$ , which is equal to $k^3 \cdot \frac{4}{3} \pi r^3$ . This means that the volume of the sphere is multiplied by $k^3$ .

a. If the radius is doubled, the volume is multiplied by 8

b. If the radius is tripled, the volume is multiplied by 27

c. if the radius is quadrupled, the volume is multiplied by 64

What is the simplified form of i^13

Nikitich [7]

Answer:

Step-by-step explanation:

$\begin{array}{lclcr}i^{1} & = &(\sqrt{-1})^{1}&=& i\\i^{2} & = & (\sqrt{-1})^{2}& =&-1\\i^{3} & = & (\sqrt{-1})^{3}&=&-i\\i^{4} & = & (\sqrt{-1})^{4}& = &1\\\end{array}$

Multiplying by i repeats the pattern .

Thus, any i⁴ⁿ = 1

If n = 3, 4n = 12, so

i¹² = 1 and

i¹³ = i¹ = i
