Check the picture.
we notice that for every pair (x, y) in Q, there is a point (-y, x) in Q',
this means that the transformation is a 90° counterclockwise rotation around the origin.
The transformation can be also noticed by sight in the figure.
Answer: 90° counterclockwise rotation
Answer:
p =
Step-by-step explanation:
Given that p varies inversely with q then the equation relating them is
p = ← k is the constant of variation
To find k use the condition p = 2 when q = 1, thus
k = pq = 2 × 1 = 2
p = ← equation of variation
Answer: 4.5 hours

Answer:
John ski down the mountain is 1285.37 feet.
Step-by-step explanation:
Given : John is skiing on a mountain with an altitude of 1200 feet. The angle of depression is 21.
To find : About how far does John ski down the mountain ?
Solution :
We draw a rough image of the question for easier understanding.
Refer the attached figure below.
According to question,
Let AB be the height of mountain i.e. AB=1200 feet
The angle of depression is 21 i.e.
We have to find how far does John ski down the mountain i.e. AC = ?
Using trigonometric,
Therefore, John ski down the mountain is 1285.37 feet.
Answer:
Step-by-step explanation:
The GCF doesn't have to be a number. In this case, it is -y because both the -2xy and -9y share it. It's also easier when you take out a negative. Once you take the GCF out, your new expression should be:
