Answer:
Here's what I get
Step-by-step explanation:
I plotted the triangles in the diagram below.
Part A
The scale factor for dilation is ½, because every coordinate has been halved.
P (8, 0) ⟶ P' (4, 0)
Q (6, 2) ⟶ Q' (3, 1)
R (-2, -4) ⟶ R' (-1, -2)
Part B
When you reflect a point (x, y) about the y-axis, the y-coordinate remains the same, but the x-coordinate gets the opposite sign. Thus,
P' (4,0) ⟶ P" (-4,0)
Q' (3,-1) ⟶ Q" (-3,-1)
R' (-1,-2) ⟶ R" (1,-2)
∆P"Q"R" has coordinates P" (-4,0), Q" (-3,-1), R"(1,-2).
Part C
∆PQR and ∆ P"Q"R" are not congruent, because corresponding sides are not equal.
Answer:
This is not a function.
Step-by-step explanation:
Note, that set A contains 3 elements that only map to 2 elements in set B. A function would require that each element of set A to match to only one element of set B.
Since set B contains an element with no mapping to an element in set A, this does not represent a function.
Solve what is in parenthesis first (5-9) = -4
Solve exponents next -4^3 = -64
Divide next
= -32
Lastly, subtract and resolve the negatives which become a positive number 125 - (-32) = 125 + 32 = 157
the answer is A cuz non of the number are repeated
Answer:
For t = 0.33 s, H = 14.0976 feet;
For t = 3 s, H = 0 feet;
For t = 16 s, H = -3328 feet;
For t = 48 s, H = -34560 feet.
Step-by-step explanation:
Assuming there's a typo on the problem and it wishes to determine the distance traveled by the ball in the given times instead of the time, we can solve it as shown below:
For t = 0.33 s:
For t = 3 s:
For t = 16 s:
For t = 48 s:
