Answers:
A''(3, 0); B''(3, 2); C''(1, 1); D''(1, -1)
Explanation:
We perform the reflection across y=x first. This reflection switches the x- and y-coordinates; this maps:
A(2, 4)→A'(4, 2)
B(4, 4)→B'(4, 4)
C(3, 2)→C'(2, 3)
D(1, 2)→D'(2, 1)
Next we perform the translation. This translation shifts the figure 1 unit left and 2 units down, by subtracting 1 from the x-coordinate and 2 from the y-coordinate. This maps:
A'(4, 2)→A''(3, 0)
B'(4, 4)→B''(3, 2)
C'(2, 3)→C''(1, 1)
D'(2, 1)→D''(1, -1)
Answer:8
Step-by-step explanation:
Answer:
<em>0.15</em>
Step-by-step explanation:
Given the expression that relates the distance and the time with the expression:
d = 0.15t
d is the distance
t is the time
To determine how fast it is flying (Speed), we will need to use the formula
Speed = distance/time
s = d/t
From the given equation we can se that 0.15 = d/t
Comparing this to the general equation, we will see that s = 0.15
<em>Hence the airplane is flying at 0.15</em>
