Answer:

The middle two terms cancel out each time, and the final product is x2 plus the product of the positive coefficients of i in the original expression. All imaginary parts either cancel out or get replaced with -1, leaving an expression that doesn’t include imaginary numbers.

Step-by-step explanation:

If the center of a circle is (1, 1), and it has a radius of 5, which is another point on the circle?
Rufina [12.5K]

Answer:

(4,5)

Step-by-step explanation:

The equation of a circle that has centre coordinates (a,b) and radius r is

(x-a)^2+(y-b)^2=r^2

so (4,5) satisfy the equation

3^2+4^2=9+16=25

Does anyone know the equation to this graph
Eduardwww [97]

Answer: The equation of this graph can be written in slope intercept form which is what I am assuming you want.  If you do not want that form you can convert to any other form that you so desire.  The slope intercept equation for this graph would be y = -1x - 2.  The -1 is the slope of the line and the -2 is the y intercept.

ive been stuck on this question for a while :( i was absent for the first half of this lesson so i dont completely know what im
Deffense [45]

Answer:

(0, 9 ) and (- 4, 1 )

Step-by-step explanation:

To determine which ordered pairs lie on the graph substitute the x- coordinate of the point into the right side of the equation and compare the value obtained with the y- coordinate

(- 20, - 49 )

2x + 9 = (2 × - 20) + 9 = - 40 + 9 = - 31 ≠ - 49

(1, 10 )

2x + 9 = (2 × 1) + 9 = 2 + 9 = 11 ≠ 10

(0, 9 )

2x + 9 = (2 × 0) + 9 = 0 + 9 = 9 ← point lies on graph

(- 4, 1 )

2x + 9 = (2 × - 4) + 9 = - 8 + 9 = 1 ← point lies on graph

(- 3, 40 )

2x + 9 = ( 2 × - 3) + 9 = - 6 + 9 = 3 ≠ 40

Find the area of the composite figure.
irga5000 [103]

Answer:

Option C, 488 square centimeters

Step-by-step explanation:

<u>Step 1:  Determine the area of the rectangle</u>

A = l * w

A = 22\ cm * 17\ cm

A = 374\ cm^2

<u>Step 2:  Determine the area of the triangle</u>

A=\frac{h*b}{2}

A=\frac{19\ cm * (22\ cm-10\ cm)}{2}

A=\frac{19\ cm * (12\ cm)}{2}

A=\frac{228\ cm^2}{2}

A=114\ cm^2

<u>Step 3:  Determine the total area</u>

A_{total} = 374\ cm^2 + 114\ cm^2

A_{total} =488\ cm^2

Answer:  Option C, 488 square centimeters
