Think of imaginary numbers on a complex plane as coordinates - take the real part, that's the x coordinate, the imaginary part that's the y coordinate.

Therefore, for the first blank, -1+3i lies in the shaded area, because its coordinates are (-1,3).
And following on from that for the second one, -4i does not lie in the shaded area, since its coordinates are (0,-4).

Tl;dr is taking a complex number a+bi and placing it on a complex plane, it will have coordinates (a,b)

Need help ASAP to this math question about how many gallons it will take to fill a pool

NARA [144]

1 cubic foot = 7.48 gallons

hence
$\frac{7.48 gal}{1 ft^3} =1$

unit conversion
$\frac{3000 ft^3}{} \times \frac{7.48 gal}{1 ft^3} = 3000 \times 7.48 gal$

3000 x 7.48 =22440

1. Find the value of x 2. Using complete sentences, describe your

aleksley [76]

Answer:

x = 40

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Consider the triangle on the left and calculate the third angle

Subtract the sum of the 2 angles from 180

third angle = 180° - (75 + 50)° = 180° - 125° = 55°

Consider the triangle on the right

The third angle = 55° ( vertical angles )

Subtract the sum of the 2 angles from 180

x = 180 - (55 + 85) = 180 - 140 = 40

Answer:

quotient: 10x +16
remainder: 28x^2 +10x +22

Step-by-step explanation:

The attachment shows the steps.

quotient: 10x +16

remainder: 28x^2 +10x +22

_____

Polynomial long division is easier than numerical long division because you only need to examine the first terms to determine the quotient term.

The first quotient term is 10x^4/x^3 = 10x.

The second quotient term is 16x^3/x^3 = 16.

When the leading dividend term is lower degree than the divisor, that dividend is the remainder.
