Can someone please help me, i am almost done with this class except for this lesson!
1. Write a piecewise function for the graph
http://www.sc.whitmoreschool.org/sec/classes/images/1995/piecewisegraph2.jpg
2. On your own paper, draw a graph to represent the total cost of the locker and the time. Then answer the questions.
If you are a member of Buff Up Gym, you can rent a locker by the hour. The cost is $2.00 per hour.
a. Is this a piecewise function? Why or why not?
b. What would the total cost be to rent a locker for 3 hours and 15 minutes?
c. Write an equation for this function.
Thank you! I don't see why they make it harder than what it really is! This really helped me !
Use the following images for questions 6 through 10:
6. In the figure above, line segment MC is equal to imaginary line segment MI.
7. In the figure above, line segment EJ is equal to line segment JM.
8. In the figure above, the measure of angle AMC is 90 degrees.
9. In the figure above, the measure of arc AC is 90 degrees
10. In the figure above the measure of angle AME is x degrees, then the measure of angle EMB is 180-x degrees.
11. In a right triangle where one side is 3, and the hypotenuse is 5, the remaining side must be 4.
12. In a triangle, if I have two angles that add up to 50 degrees, the remaining angle must be 130 degrees.
13. The diameter of a circle always passes through the midpoint of the circle.
14. If a central angle is 30 degrees, then the arc it defines is also 30 degrees.
15. The area of a sphere is 4 times the area of a circle with the same radius.
16. If a radius bisects a chord, then the lengths of the parts of the radius on either side of the chord are equal.
17. If a circle has a central point M, and both point A and point D are on the circle, then ls_MA and ls_MD will be equal.
18. If I have two points, (-2, -3) and (-4, 4) then the distance between them is sqrt(53).
19. The given points (4, -8), (4, -5), and (-2, -6) make a right triangle.
20. The given points (2, -3), (-7, -7), (2, -7), and (-7, -2) make a square.
There's a picture to go along with this. I don't know if it posted. Will have to get on the laptop tomorrow. Goodnight.
It's 10:30 here. Just email me when you get the chance and ill most likely be awake. Doesn't matter what time.
I don't really understand I have two lesson left in my online course and then I'm done but the way they format the problems make them Confusing. I can't access the questions right now to show all of them, I think there's 20 questions in total so I'll get back to you tomorrow.
Someone please help! I am stuck on proofs!
State whether the following are given, unfounded or covered by a particular definition. Provide the explanation for your selection:
1. If I have two coplanar lines, I must have a plane.
2. There are two adjacent angles whose outside edges form a straight line. The measure of the first angle is 100 degrees, so the measure of the other must be 80 degrees
3. I have drawn a polygon with eight sides, so it must be an octagon.
4. A square has two diagonals.
5. If the diameter of the circle is 12, the radius must be 6.
Thank you! I finally got the answers right! Now I am stuck on proof, could you help ?
Someone please help! I have tried to get the answers. My teacher has explained it to me but I still don't understand.
18. The translation of triangle BPU (-36, 20), (28, 16), and (8, 12) after a dilation is (9, -5), (-7, -4), and (-2, -3). What is the dilation? The scale factor is a fraction. The triangle is smaller than the original. The dilation is a contraction.
19. The translation of triangle GEP (-4, 10), (-9, -3), and (-6, 6) after a dilation is (-28, 70), (-63, -21), and (-42, 42). What is the dilation? The triangle is getting bigger than its original size.
20. The translation of triangle KTS (6, -36), (-60, 72), and (-54, -36) after a dilation is (1, -6), (-10, 12), and (-9, -6). What is the dilation? The triangle is getting smaller than the original, this is a contraction.
Hi;
I am working on the same thing and its asking for reasons as to why these are True or False.
can someone please help. I got the answers stating true or false but I cannot figure out why.
