Step-by-step explanation:
If a triangle is rotated 90° about the origin.
The rule that describes the transformation is
(x, y) → (–y, x)
Answer:
Step-by-step explanation:
Area of the figure = Area of the arc with radius 10 yd and central angle 90° + Area of rectangle with dimensions (10 + 5 - 3 = 12) 12 yd and (7 + 6 - 4 = 9) 9 yd + Area of square with dimension 4yd + Area of rectangle with dimensions 3 yd by 2 yd + Area of triangle with base 3 yd and height (5 + 3 = 8) 8 yd.

Answer:
Graph (C)
Step-by-step explanation:
If Bob traveled 'y' miles in 'x' hours,
Distance traveled ∝ Time taken to cover the distance
y ∝ x
y = mx
Here, m = proportionality constant Or slope of the line
Since, Bob covered 45 miles in 1.5 hours,
m = 
m = 30 miles per hour
From the given graphs,
Graph (C) shows the slope = 
= 
= 30 miles per hour
Therefore, Graph (C) will show the relationship.
