Answer:
(1,-1)
Step-by-step explanation:
if its asking for a reflection on the x-axis, change the y's to the opposite of what it is.
Example, (5,6) change it to (5,-6)
its the same thing for the reflection on the y-axis
(7,-8) change it to (-7,-8)
Answer:
1.5 h
Explanation:
We know that distance travelled (d) equals rate of travel (r) times time (t) spent in travel. In symbols,
d = rt or rt =d
When Leah starts, Raul is already 30 min (0.5 h) ahead.
So, let t time for Leah and t + 0.5 be the time for Raul.
For Raul: 3(t+0.5) = d
For Leah: 4t = d
When Leah catches up with Raul, both will have travelled the same distance. So,
3(t+0.5) = 4t Remove parentheses
3t + 1.5 = 4t Subtract 3t from each side
t = 1.5 h
It takes Leah 1.5 h to catch up with Raul.
===============
<em>Check:
</em>
Distance travelled by Raul = 3 × (1.5 + 0.5) = 3 × 2 = 6 mi
Distance travelled by Leah = 4 × 1.5 = 6 mi
The area of a circle is A=pi(r)^2. Since the diameter is 13, the radius would be 6.5. Doing the formula (3.14)(6.5)^2, the answer would be 132.665.

= 4.5 x 360 degrees
=1620
