Answer:
Area of the rectangle is increasing with the rate of 84 cm/s.
Step-by-step explanation:
Let l represents the length, w represents width, t represents time ( in seconds ) and A represents the area of the triangle,
Given,
Also, l = 12 cm and w = 4 cm,
We know that,
A = l × w,
Differentiating with respect to t,
By substituting the values,
Hence, the area of the rectangle is increasing with the rate of 84 cm/s.
Answer:
5/2
Step-by-step explanation:
Answer:
Part A: The scale factor of the dilation that transforms triangle PQR to triangle P'Q'R' is 1/3. This is because triangle P'Q'R is smaller than PQR by 1/3
Part B: The coordinates after P"Q"R" are P"(1, -2) Q"(0, -3) R"(-1, 0)
Part C: No the triangles are not congruent because they are not the same size. If there wouldn't have been a dilation or reflection then it would've been congruent.
Step-by-step explanation:
I did this Exam already and got a 100% good luck.
So I drew a number line , & I placed point e at 1 1/4 . The correct answer will be B . It couldn't be A because if point e was 1/4 to the left of 1 , point e will be located at 3/4 . But because it ask to put point e at 1 1/4 , you would look for 1 & just move up 1/4 .
