To illustrate the problem, refer to the following diagram, made with the ever-helpful notepad application:
|\ | \ | \h| \ | \ | \ |_____q\ x
Pretending as if that is a wonderfully-drawn triangle, we are given the distance x of the observer from the launch pad. The angle q is also stated, and is located in the diagram as shown. To look for the distance h of the tip of the rocket to the ground, we consider the following trigonometry function:
tan q = h/x
Since we are solving for h, we multiply both sides with x, giving us:
h = x * tan q
Among the choices, the correct answer is C.
Answer:
approx 7.81 Exactly: √61
Step-by-step explanation:
Use Pythag theorem: 5^2 + 6^2 = hyp^2 (line AS)
25 + 36 = 61
hyp = √61 or about 7.81
Answer: 7/145
Step-by-step explanation:
The probability that the first student walks to school will be: = 7/30.
The probability of selecting the second student that walks to school will be: = 6/29.
Then we multiply both together and this will be:
= 7/30 × 6/29
= 7/145
Answer:
y = 2x
Step-by-step explanation:
Note the relationship between x and y, that is
x = - 42 → y = - 84 ← that is y = 2x
x = - 14 → y = - 28 ← that is y = 2x
x = 14 → y = 28 ← that is y = 2x
x = 42 → y = 84 ← that is y = 2x
Thus the linear equation is y = 2x
