Attached is graphed piecewise function.

Take note, if the inequality is a less than or equal to or (more than or equal to), the dots will be solid, otherwise it will be hollow.

Since this is a piecewise function, here is one question you might want to ask yourself:

Does the limit exist when x approaches 4?

After 24 hours, 35.4% of the initial dosage remains on the body.

The exponential decay is written as:

[tex]f(x) = A*e^{-k*x}[/tex]

Where A is the initial value, in this case 2.8mg.

k is the constant of decay, given by the logarithm of 2 over the half life, in this case, is:

[tex]k = ln(2)/16h[/tex]

Replacing all that in the above formula, and evaluating in x = 24 hours we get:

[tex]f(24h) = 2.8mg*e^{-24h*ln(2)/16h} = 0.9899 mg[/tex]

The percentage of the initial dosage that remains is:

The z-scores of the scores are -1.34, -0.73, 0.48, 0.48 and 1.10

The sample scores are given as:

2, 3, 5, 5, 6.

Calculate the mean and the standard deviation using a statistical calculator.

From the statistical calculator, we have:

[tex]\bar x = 4.2[/tex] --- mean

[tex]\sigma_x = 1.64[/tex] --- standard deviation

The z-score is then calculated using

[tex]z= \frac{x - \bar x}{\sigma}[/tex]

Where:

x = 2, 3, 5, 5, 6.

So, we have:

[tex]z_1= \frac{2 - 4.2}{1.64} = -1.34[/tex]

[tex]z_2= \frac{3 - 4.2}{1.64} = -0.73[/tex]

[tex]z_3= \frac{5 - 4.2}{1.64} = 0.48[/tex]

The complement of the given set is:

A* = {-1, 0, 1, 4, 5}

For any set A on a universal set U, such that:

Sadly we don't have the original function f(x), but we can answer in a general form.

Remember that for a general function f(x), a horizontal translation of N units can be written as:

y=x^2+2x-3 is the similar to x^2+2x-3=0 because the letter y now represents zero. So, that's why we draw the line y=0 (a horizontal line at zero). Then, use it to find the x values.

Answer:

Step-by-step explanation:

the answer is the y intercept of the equation

Answer:

23m, at t=2s

Step-by-step explanation:

Putting the physics part aside, you can rewrite the height function as

[tex]h(t)= 23 - 5(t-2)^2[/tex]. Now you have a fixed value, 23, and you're subtracting to it a quantity that, being a square, is at least zero. The maximum value of that sum you have when you're not subtracting anything, that is 23. That happens when [tex]5(t-2)^2 = 0 \rightarrow t=2[/tex]

Step-by-step explanation:

Hello!

Solve for y by isolating the variable.

The solution is y = 2x + 3.

To Calculate :-

Solution :-

⇒ -20x + 10y = 30

☆ Transposing (-20x) to R.H.S. sign would be changed to positive.

⇒ 10y = 30 + 20x

⇒ y = 30 + 20x / 10

⇒ y = 10 (3 + 2x) / 10

☆ Cancelling 10,

⇒ y = 3 + 2x / 1

⇒ y = 2x + 3

medium, and large. A glove pattern is first stenciled onto leather in the Pattern Department. The stenciled patterns are then sent to the Cut and Sew Department, where the glove is cut and sewed together. Handy Leather uses the multiple production department factory overhead rate method of allocating factory overhead costs. Its factory overhead costs were budgeted as follows:

Pattern department Overhead                $140,700

Cut and sew Department overhead        $231,400

Total    $372100

Direct labor labor estimated for each department was as follows:
