Answer:
D. 135.37 in²
Step-by-step explanation:
We have that the gift paper consists of two circles and a square.
Thus, we will need to find the area of the circles and the square.
Now, as the diameter of the circle = 4 inches
So, the radius of the circle = = 2 inches
Since, the area of a circle =
This implies that area of the two circles =
i.e. Area of the circles =
i.e. Area of the circles =
i.e. Area of the two circles = 25.133 in²
Further, one side of the square = 10.5 inches
Thus, the area of the square =
i.e. Area of the square =
i.e. Area of the square = 110.25 in²
So, the overall area of the gift paper = 25.133 + 110.25 = 135.37 in².
Hence, the amount of paper used by Angela is 135.37 in².
Answer:
The Slope of Line 1 is ->
The Slope of Line 2 is ->
These two lines are - > Perpendicular
Step-by-step explanation:
To find the slope of line one, you follow these steps:
First Coordinate 10 -> x1, 5 -> y1
Second Coordinate -8 -> x2, 9 -> y2
Then insert the assigned values into this equation: ->
which equals
which simplifies to
Then do the same process to find the slop of line 2:
First Coord: 2 -> x1, -4 -> y1
Second Coord: 11 -> x2, -6 -> y2
Then insert the values into this equation: ->
which equals
.
We know the lines are perpendicular by:
a. Typing the equations of the lines into a graphing calculator and observing the graph
b. Looking at the slopes. By looking at the slopes, we see that the slope of line 1 is the reciprocal of line 2, and vice versa. Since reciprocal slopes indicate perpendicular lines, the lines 1 and 2 are perpendicular to each other.
Hope this helps!
