Remember that the graph of the inverse of a function f(x) is the reflection of that graph in the line y=x. Draw the line y=x on top of the graph shown above, and then reflect the graph about the line y=x. The graph of the inverse of f(x) is identical to the graph of f(x).

Murrr4er [49]

Answer:

Use the equation h(t)=-b/2a to find the x value of the vertex, then plug that back into the equation to find the y value which is your height.

Step-by-step explanation:

You can also complete the square to get the equation into vertex form, then your height is the y value of your vertex. Remember the maximum height is always at the vertex of an inverted parabola.

In a lab experiment, the decay of a radioactive isotope is being observed. At the beginning of the first day of the experiment t

GaryK [48]

Using an exponential function, it is found that the mass of the radioactive sample at the beginning of the 13th day of the experiment was of 169.1 mg.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

$A(t) = A(0)(1 - r)^t$

In which:

A(0) is the initial value.

r is the decay rate, as a decimal.

At the beginning of the first day of the experiment the mass of the substance was 500 grams and mass was decreasing by 8% per day, hence A(0) = 500, r = 0.08, and the equation is given by:

$A(t) = A(0)(1 - r)^t$

$A(t) = 500(1 - 0.08)^t$

$A(t) = 500(0.92)^t$

At the 13th day, the mass is given by:

$A(13) = 500(0.92)^{13} = 169.1$

Answer: B

Explanation:
(75 + 90)/250 = 0.66 = 66% of students are 11 or 12
5/250 = 0.02 = 2% of students are 10
(90 + 70)/250 = 0.64 = 64% of students are 12 or 13
10/250 = 0.04 = 4% of students are 14
