Answer:
c) 1.8 miles
Step-by-step explanation:
Assuming Kayla walks at a constant speed, we have ...
miles/minutes = 3.2/45 = x/25
x = 25(3.2/45) = 1.777... ≈ 1.8 . . . . miles
Kayla walks about 1.8 miles in 25 minutes.
Answer:
a) J':(-7,7) K':(-5,2) L':(-2,3)
b) The x coordinates remained the same, the y coordinates swapped from negative to positive.
Step-by-step explanation:
Aside: I'm using J', K', and L' to denote the new locations of J,K,L after the reflection.
When an object is reflected over the x-axis, it means it's positive points will flip to negative y space, and negative points will flip to positive y space.
That said, J, for instance, will have the same X-coordinate, but its Y-coordinate will flip from negative to positive. Doing this with every vertex mirrors the triangle over the X-axis.
Therefore, J:(-7,-7) will become J':(-7,7), and likewise with K and L becoming K':(-5,2) and L':(-2,3).
A, B and C but I’m contemplating D too but it’s def not E or F
<span>For the answer to the question above, according to Weber's law, the perceptible differences are proportional to the initial perception. So, with just a 10% increase in area was perceptible, but an increase of 1-9% in the area is considered imperceptible. The 9% increase in area reflected by 200 to 218 would be perceived as the same size as before.
The <u><em>answer is 218</em></u></span>
