Answer for y is = 5x/2 - 17/2
Answer:
1. 23.59 feet
2. 32.9°
Step-by-step explanation:
1. See the diagram attached.
The man is 11 feet distance from the bottom of the tree.
And the angle of elevation from the man to the top of the tree is 65°.
Now, we need to approximate the height of the tree,
Using the trigonometry, we can write
⇒ h = 11 tan 65° = 23.59 feet (Approx.) (Answer)
2. See the diagram attached.
From the given right triangle the hypotenuse is 25 feet and the base is 21 feet.
And the angle between the hypotenuse and the base is the pitch of the ram of a NASCAR turn.
Using trigonometry, we can write
⇒
(Answer)
Answer:
The median score of class A is 73
The interquartile range of class B is 8
The difference of the medians of class A and class B is 9
the interquartile range of either data set should be 8 because that is what b was.
Step-by-step explanation:
The interquartile range is the difference between the upper quartile and the lower quartile. In example 1, the IQR = Q3 – Q1 = 87 - 52 = 35. The IQR is a very useful measurement. It is useful because it is less influenced by extreme values as it limits the range to the middle 50% of the values.
Answer:
about 7.2 I think
Step-by-step explanation:
if his pay went up all the way to 770 it would be going up either 7.8 or 7.2
3^6 power. it would be 3 to the 6th power
