d = 2 × 5inch

d = 10 inch

The radius is . . .

r = 5 inch

The circumference is . . .

C = πd

C = 3,14 × 10 inch

Focus tests suggest that costumers love the new gPhone X1, but they think the 5.82-inch long screen is too long. The engineers c

mojhsa [17]

Length of X1 = 5.82"
Length of X2 = 5.82" - 5/8 of an inch
= 5.82" - 0.625" = 5.195"

Length of Rover 6 = 5.2"

5.195" < 5.2 "

The X2 is going to be 0.005" shorter than the Rover 6

Which operations involving complex numbers have solutions represented by point A on the graph? PLEASE HELP

Alina [70]

Answer:

Option 3 and 4

Step-by-step explanation:

We have to find the solutions represented by point A on graph

The point A is represented by (-6,7i)

Lets check all options one by one

$2(1-2i)-(4+3i)\\= (2-4i)-(4+3i)\\=2-4i-4-3i\\=2-4-4i-3i\\=-2-7i$

This option is not correct

$2(1+2i)+(-4-3i)\\=(2+4i)-4-3i\\=2+4i-4-3i\\=2-4+4i-3i\\=-2+i$

This option is also not correct

$2(-1+2i)-(4-3i)\\=(-2+4i)-4+3i\\=-2+4i-4+3i\\=-2-4+4i+3i\\=-6+7i$

This solution is same as point A so this option is correct

$(-2+4i)+(-4+3i)\\=-2+4i-4+3i\\=-2-4+4i+3i\\=-6+7i$

Solution same as point A so this is correct option.

$(-2-4i)+(4-3i)\\=-2-4i+4-3i\\=-2+4-4i-3i\\=2-7i$

Not correct

The correct options are option no 3 and 4 ..
