Answer: when looking at the graph, anything that is going down is decreasing and anything that is going up is increasing. Maybe that can help you.
Step-by-step explanation:
Answer: 
Step-by-step explanation:
You have the following information given in the problem:
- The number of soccer fans that are going to a soccer game is 27.
- A ticket to the game costs $18 per person.
- The cost of the lunch for all 27 fans is $172.
-
represents the total cost of attending the game for all 27 fans.
Therefore, keeping the above on mind you can write the following expression that closely estimates the total cost of attending the game for all 27 fans:

If the apple is on the ground, then the height y is 0. To find t, just plug in 0 for y:




So the answer is 2.74 seconds.
Note that taking the square root of 7.5, mathematically, gives you both 2.74 and -2.74. But because we know that time did not go backwards, only the positive value for t was considered.
Answer:56.8 inches
Step-by-step explanation:
For perimeter we must find the lengths of the 2 diagonal sides of the triangle which are the same because it is isosceles.
the triangle is cut directly in half so both halves of the base are 17/2
17/2 = 8.5
solve through pythagoren theorum
altitude^2 + (half of base)^2 = (diagonal length)^2
18^2 + (8.5)^2 = (diagonal length)^2
324 + 72.25 = (diagonal length)^2
396.3 = (diagonal length)^2
= diagonal length
diagonal length = 19.9
diagonal length + diagonal length + base = perimeter
19.9 + 19.9 + 17 = perimeter
56.8 inches = perimeter
