Answer/Step-by-step explanation:
Recall: if two figures are similar, we know that the ratio of their areas = the square of the ratio of their corresponding sides
Apply this knowledge to solve the problems given.
✔️Problem 1 (4-sided polygon):
Let the missing area be x cm²
Therefore,
Multiply both sides by 9
x = 9*4
x = 36 cm²
✔️Problem 2 (3-sided polygon):
Let the missing area be y cm²
Therefore,
Multiply both sides by 240
y = ¹/16 × 240
y = 15 cm²
✔️Problem 3 (5-sided polygon):
Let the missing area be z cm²
Therefore,
Multiply both sides by 40
z = 90 cm²
Answer:
I belive it is 15
PLZ CORRECT ME IF I AM WRONG PLEASE AND THANK YOU
Step-by-step explanation:
Hello!
Scientific notation is a number multiplied by 10 to the power of something
So the answers are the first one and the last one
Hope this helps!
We will have the following:
A. The function is compressed in the y-axis by a factor of 0.5 and then it is inverted in its direction; since it is a line the line is then decreasing instead of increasing.
B. The function is increased by a factor of 2 in the y-axis and then it is moved 3 units up:
C. The function is increased by a factor of 5/3 (Approximately 1.67) in the y-axis and then it is made so it is no longer increasing, but decreasing:
D. The function is increased in the y-axis by a factor of 9 and then it is moved 9 units down:
Using transformation rules, it is found that the correct option is:
No, A'C'B' is located at A(-1,1), C'(-3,4) and B'(-5,1).
--------------------
- The transformation rule for a reflection over the x-axis is
- The transformation rule for a rotation of 180º is
- After the reflection over the x-axis:
- Taking the reflection, and rotating:
. - Not the same rule, that is,
, so it would not map figure onto itself. - A(1,1) would be mapped to A(-1,1), for example, thus, the correct option is:
No, A'C'B' is located at A(-1,1), C'(-3,4) and B'(-5,1).
