Answer:

A. Real numbers from 0 to 8.

Step-by-step explanation:

Since, the given graph represents the depth of water pumped out of the backyard pound,

So, time ( in minutes ) must show the input value and depth ( in inches ) must show the output value,

Also, by the given graph,

Time is defined from 0 to 8 minutes,

Thus, the possible input values of the function of the graph are all the real number between 0 to 8,

Now, we know that the set of all possible input values is called domain of the function,

Hence, the domain of the given graph is,

Real numbers from 0 to 8.

Option 'A' is correct.

We are able to set 4x+32 equal to 6x-8 because these are congruent vertical angles

4x+32=6x-8
4x+40=6x (add 8 to both sides)
40=2x (subtract 4x from both sides)
X=20 (divide both sides by 2)

Then we plug in 20 for x into 6x-8 to find the answer

6(20)-8
=120-8
=112

Hope this helps!

The density of titanium is 4.51 g/cm^3

forsale [732]

The volume of titanium is 20.86 cubic inches

Solution:

The volume is given by formula:

$volume = \frac{mass}{density}$

From given,

Density of titanium = 4.51 $g/cm^3$

Mass = 3.4 lb

Let us convert the mass to grams

1 pound = 453.592 grams

Therefore, 3.4 pound is equal to:

$3.4 \text{ pound } = 3.4 \times 453.592 \text{ grams }\\\\3.4 \text{ pound } = 1542.2128\text{ grams }$

Now substitute the values into formula:

$volume = \frac{1542.2128}{4.51}\\\\volume = 341.95 cm^3$

Let us convert cubic centimeter to cubic inches

1 cubic centimeter = 0.0610237 cubic inches

Therefore,

$341.95\ cm^3 = 0.0610237 \times 341.95\ in^3 = 20.86\ in^3$

Thus volume of titanium is 20.86 cubic inches

Sixty seven percent of the employees in a company have managerial positions, and 58 percent of the employees in the company have

Kazeer [188]

Answer: The proportion of employees who either have MBAs or are managers are 0.58.

Step-by-step explanation:

Since we have given that

Probability of employees having managerial positions = 67%

Probability of employees having MBA degrees = 58%

Probability of managers having MBA degrees = 67%

So, using probability formulas, we get that

$P(A\cup B)=P(A)+P(B)-P(A\cap B)\\\\P(A\cup B)=0.67+0.58-0.67\\\\P(A\cup B)=0.58$

Hence, the proportion of employees who either have MBAs or are managers are 0.58.

The image below shows the graph of a sound recorded on an oscilloscope. What are the period and the amplitude? (Each unit on the

Serhud [2]

Remember that the period of a sinusoidal function is the vertical distance between the t-axis and one of the extreme points. From the graph we can infer that the period of the function is 4.5.

Also, the amplitude is the distance between two consecutive maximum or two consecutive minimum points. From the graph we can infer that the amplitude of the function is 0.05 seconds.

We can conclude that the correct answer is: 0.05 seconds; 4.5
