Part A) x-intercepts simply show that when the value of the function is zero. Vertex coordinates show that when the function obtains its maximum value. When x=50, function obtains its maximum value and it's 75. The function is increasing in the interval (0, 50) and decreasing in the interval (50, 100). In regard to the height and distance of the tunnel, these numbers show that decreasing and increasing intervals are symmetric. Each number from the intervals has its own pair in the corresponding interval and they are located in the same distance from the midpoint (50,75)

Part B) In order to calculate the average rate of change, we can first write the function. Using the information about the x-intercept and the vertex coordinates, we find that our function is f(x)=-0.03x^{2}+3x.
Plugging 15 and 35 in x, we can find the values of the function, i.e. 
f(15)=38.25 and f(35)=68.25.
Then, the average change is \frac{68.25-38.25}{35-15}=1.5

Help me with both questions <br>plz read carefully so you can help me
Scrat [10]

Answer:

2. Both

3. e = 3, f = -5, g = 2

Step-by-step explanation:

2. Order doesn't affect product

3. You get e • f = -15, e • g = 6, f • g = -10 from the problem.

   e = -15/f    (solve for e)

   (-15/f) • g = 6    (plug into second equation)

   (-15g/f) = 6    (multiply)

   -15g = 6f    (multiply)

   (-5g/2) = f    (divide)

   (-5g/2) • g = -10    (plug into last equation)

   (-5g^2)/2 = -10    (multiply)

   -5g^2 = -20    (mulitply)

   g^2 = 4    (divide)

   g = 2    (square root)

   e • g = 6    (plug in for g, solve for e)

   e • 2 = 6

   e = 3

   f • g = -10    (plug in for g, solve for f)

   f • 2 = -10

   f = -5

I don't know if your teacher made a typo because I tried this multiple times and got the same answer. I don't know how e is negative.

A tangent is &gt;insert answer here&lt; to the radius that shares the point of tangency
tatuchka [14]
A tangent line is always perpendicular to the radius that shares the point of tangency.  In other words, where your tangent line touches the circle (at only one point), that line is perpendicular to the radius at that point.

What is the domain of f(x)=(1/4)^x?
atroni [7]

\huge \bf༆ Answer ༄

The domain of given function is <u>All real numbers</u>

\sf \: f(x) = { \bigg( \dfrac{1}{4}  \bigg) }^{x}

For each value of x the function is defined.

Example -

  • For x = 1

The value is \sf\frac{1}{4}

  • For x = -1

The value is 4
