Answer:
Situation <u>3</u> does not represent a function.
This is because <u>the same number of credit cards can have different totals.</u>
(0,4) (0,-2) (-2,0)
for the reflection over the x-axis, all the y values go to their opposite (0,-4) (0,2) (2,0)
then at the rotation it goes (-x,-y) and becomes (0,4) (0,-2) (-2,0)
Answer:
30 hours.
Step-by-step explanation:
Richard can build 15 snowballs in 1 hour
But 2 snowballs melt every 15 minutes
In 1 hour, the number of snowballs that will have melted is:
× 2 = 8
The number of snowballs that will have remained = 15 - 8 = 7
So 7 snowballs will have remained in 1 hour
For 210 snowballs to have remained, it will take:
× 1 = 30 hours.
The smallest possible measure of angle h is 90 degrees. Since f and g are complementary angles ( add up to 90 degrees), the h has to at minimum be 90 degrees to equal 180 degrees (supplementary angles).
