Triangle END is reflected across the line y = x using the rule (x, y) → (y, x) to create triangle E′N′D′. If a line segment is d

rawn from point E to point E′, which statement would best describe the line segment drawn in relation to the line y = x?
A-Both are congruent to each other.
B- Both create diameters of concentric circles.
C- They are parallel.
D- They are perpendicular.

Answer:

They are perpendicular.

Step-by-step explanation:

Step-by-step explanation:

For example, if we have the point E (1, 2) and E' (2, 1)

we can get the slope as follows

m' = (yE' - yE) / (xE' - xE)

⇒ m' = (1 - 2)/(2 - 1) = -1 / 1 = -1

Now we have the slope of the line y = x, which is m = 1

we can apply

m*m' = (1)*(-1) = - 1

we can say that they are perpendicular.

A ball is thrown upward from the top of a building. The function below shows the height of the ball in relation to sea level, f(
gavmur [86]
We have the following function:
 f(t) = −16t2 + 34t + 546
 By definition, the average rate of change is:
 Avr = (f (t2) - f (t1)) / (t2 - t1)
 We have then:
 For t1 = 5:
 f (5) = -16*(5)^2 + 34*(5) + 546
 f (5) = 316
 For t2 = 5:
 f (7) = -16*(7)^2 + 34*(7) + 546
 f (7) = 0
 Substituting values:
 Avr = (0 - 316) / (7 - 5)
 Avr = -158
 Answer:
 The average rate of change of f (t) from t = 5 seconds to t = 7 seconds is -158 feet per second.
