Answer:
.
Step-by-step explanation:
We need to write an equation for the amount of chemical B as a function of the amount of chemical A.
...(1)
where, k is constant of proportionality.
It is given that fifteen grams of chemical A is used to produce 3 grams of chemical B. It means a=15 and b=3.
Substitute a=15 and b=3 in (1).
Substitute 
in (1).
Therefore, the required function is .
For different function different results are shown below.
<h3>What is Function?</h3>
A function is a process or a relation that associates each element 'a' of a non-empty set A , at least to a single element 'b' of another non-empty set B.
We have been given a graph of piecewise function. Using that we have to select the function from given choices which is represented by graph.
g(x) = −2x, −2 < x < 0
Answer:
NO. Because g(x) = −2x has negative slope so that means it goes downward also there is no y-intercept in g(x) = −2x but the only graph that has y-intercept in given graph goes upward so that can't be answer.
g(x) = −2, x < −2
Answer:
YES. Because g(x) = −2 is a horizontal line which is only on the left side of x=-2. Graph of this part is present in given graph. So yes it is answer.
g(x) = x − 2, −2 < x < 1
Answer:
NO. Because g(x) = x−2 has y-intercept at y=-2 and slope 1 so that means graph of g(x)= x-2 must be going upward and crossing at y=-2 but there is no such graph. Hence this can't be answer.
g(x) = −2x + 6, x ≥ 1
Answer:
YES. Because g(x) = −2x+6 satisfies the graph which is going downward.
g(x) = x/2+ 1, –2 ≤ x < 1
Answer:
YES. Because g(x) = x/2+ 1 satisfies the graph which is going downward.

A. 8 and x are the same length, so x is 8 and y is 16
B. Same thing. Y and 25 are the same, so y is 25 and x is 50
Answer: 3 ft 8 in
<u>Step-by-step explanation:</u>
The sum of their wingspan is the circumference of the tree.
Use the formula: C = πd to find the diameter (d) of the tree.
5'6" + 6' = 11'6" = 11.5 ft
11.5 ft = πd → 11.5/π = d → 3.66 ft = d
Next, convert the decimal (feet) into inches
which means the decimal of .66 ft rounds to 8 in
⇒ d = 3 feet 8 inches (3' 8")
