Simplify showing all steps:
$4i( (1)/(2)i)^2(-2i)^2$

Answers

Answer 1

Answer: we know that i=√-1
so we do pemdas
$(1)/(2) i$ = $( √(-1) )/(2)$
exponents
$( ( √(-1) )/(2) )^(2)= (( √(-1) )^(2))/(2^(2))$ = $(-1)/(4)$
then $(-2i)^(2)$ =-2 times -2 times i times i=4 times -1=-4
now we have

$4i( (-1)/(4) )(-4)$ = $( (-4i)/(4) )(-4)$ = $( -i)(-4)$ =4i=aprox 4√-1

the answer is 4i

Which is the graph of linear inequality 2y > x – 2?

Answers

The graph of linear inequality (2y > x – 2) can be drawn by determining the x-intercept and y-intercept of the equation (2y = x - 2).

Given :

Inequality -- 2y > x – 2

The graph of the inequality can be drawn by using the following steps:

Step 1 - First find the y-intercept by putting (x = 0) in equatiuon (2y = x – 2).

$2y = -2$

y = -1

Step 2 - Now, find x-intercept by putting (y = 0) in equatiuon (2y = x – 2).

$0=x-2$

x = 2

Step 3 - Now, draw the line that passes through (0,-1) and (2,0).

Step 4 - Now, shade the upper part of the line, the resulting graph is the graph of (2y > x – 2).

Therefore, the correct option is C).

A cylinder has a height of 13 meters. It's volume is 4,082 cubic meters. What is radius of the cylinder?

Answers

Answer:

the radius is 10 m apprx

Step-by-step explanation:

height of the cylinder = $\pi r^(2) h$ = 4082 $m^3$

then $r^(2)= (4082)/(13\pi ) = 99.9493$

r= $√(99.9493)$ =10.0 m
