3. Janet is flying a kite on a string that is 75m long. The kite is 62m above the ground. Estimate the distance between Janet an
konstantin123 [22]
Answer: a) It will be a right triangle with a hypotenuse of 75 and a vertical leg that is 62. 
b) The length of the kite string is 75 (given in the problem). However, I believe you are looking for the distance from the spot on the ground beneath the kite to Janet. That is about 42.2 m.

To find the missing distance in the right triangle. You have to use the Pythagorean Theorem.  I set it up and solve it below.

a^2 + b^2 = c^2
x^2 + 62^2 = 75^2
x^2 + 3844 = 5625
x^2 = 1781
x = 42.2 (about)

A treasure map says that a treasure is buried so that it partitions the distance between a rock and a tree in a 5:9 ratio. Marin
Tanya [424]
Let the coordinates of the treasure be (x,y).
Let d_{1} =  distance from the rock to the treasure.
Let d_{2} =  distance from the tree to the treasure.
 d_{1} = \sqrt{(x\2 + (y-2)^2}
d_{2} = \sqrt{(16-x)^2 + (21-y)^2}
We want \frac{ d_{1} }{ d_{2} } = 5/9 in order to locate the treasure. 

Note that 5/9 = 0.556 (approx)
Test (11.4, 14.2)
d1 = 14.8, d2 = 8.2, d1/d2 = 1.8           Incorrect
Test (7.6, 8.8)
d1 = 8.2,  d2 = 14.8,  d1/d2 = 0.554    Correct
Test (5.7, 7.5)
d1 = 6.13,  d2 = 16.98,  d1/d2 = 0.36   Incorrect
Test (10.2, 12.6)
d1 = 12.8,  d2 = 10.2,  d1/d2 = 1.255   Incorrect

Answer: The correct answer is (7.6, 8.8)

Answer:

\boxed{f(6) = 34}

Step-by-step explanation:

Composition of functions occurs when we have two functions normally written similar or exactly like f(x) & g(x) - you can have any coefficients to the (x), but the most commonly seen are f(x) and g(x). They are written as either f(g(x)) or (f o g)(x). Because our composition is written as (f \circ g)(2), we are replacing the x values in the g(x) function with 2 and simplifying the expression.

g(2) = 3(2)

g(2) = 6

Now, because we are composing the functions, this value we have solved for now replaces the x-values in the f(x) function. So, f(x) becomes f(6), and we use the same manner as above to simplify.

f(6) = (6)^2-2

f(6) = 36-2

f(6) = 34

Therefore, when we compose the functions, our final answer is \bold{f(6) = 34}.
