Answer:
They sound like objectives for a unit of a math or economics class.
Step-by-step explanation:
Data collection would most likely mean analyzing collected data (looking for trends).
Constructing graphs would probably mean making graphs from a set of data (plotting the information).
Interpreting graphs would mean the opposite of the above definition: would look at a graph and then put that information into written form/
Drawing a line of best fit means making a line on a graph that represents the average of all of the data on the graph.
I hope that this helps!
Is it 5+7+11 ???????????????????????????
Answer:
20.00+12.76 would give you that sum
Step-by-step explanation:
Answer: 23.09 m
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Tan α = opposite side / adjacent side
Where α is the angle of elevation that the dog is looking up, the opposite side (x) is the height of the tree house, and the adjacent side is the distance between the dog and the tree house base.
Replacing with the values given:
Tan 30 = x/ 40
Solving for x
tan30 (40) =x
x= 23.09 m
Feel free to ask for more if needed or if you did not understand something.
Answer:
a=9
Explanation:
The triangle is a 45-45-90 triangle, so the sides have a 1-1-root 2 ratio. So, if 9 root 2 is to root 2, then find a to 1. You can solve this by setting up the ratio and solving for a:
a/1=9root2/root2
a/1=9
a=9
