Answer:

So ummmm..... I personally think that all of your answers on the first page should be flipped.

Second page:

#9: domain= [0,6] range=[-6,6]

#10: Domain= (-infinity, infinity) range: (-infinity, infinity)

#11: Domain= (-infinity, infinity) range: [-2, infinity)

11. The given graph can be described by the following real life situation;

Second page;

The domain and range of a

The domain of a function is set values of the input to the function where the function is defined

The range of a function are is the set of the output values of the function

9. The given figure of a square is not a function

10. The graph extends to infinity towards the top right, and the bottom left

11. The graph of the function extends infinity at the top left and top right

The graph has a minimum at y = 2, while it extends to infinity as the y-values increases, therefore;

12. The graph of a circle is not a function

13. The end behavior of the graph is as follows;

The graph is repeating and extending to infinity at the left and right ends

Therefore;

The maximum y-value is y = 4, the minimum y-value is y = -2, therefore;

14. The graph of the function is an horizontal line, y = 1, extending to infinity to the left and right, therefore;

Therefore;

Answer:

She went on the slide 8 times and on the roller coaster 4 times

Step-by-step explanation:

We convert each statements to a mathematical equation.

Firstly, let's represent the number of times she went on the coaster with R and the number of times on the slide with S. We know quite well she went on 12 rides. Hence the summation of both number of times yield 12.

Mathematically, R + S = 12. ........(i)

Now we also know her total wait time was 3hours. Since an hour equals 60 minutes, her total wait time would equal 180 minutes.

To get a mathematical representation for the wait time, we multiply the number of roller coaster rides by 25 and that of the slides by 10.

Mathematically, 25R + 10S = 180 .......(ii)

Here we now have two equations that we can solve simultaneously.

From equation 1 we can say R = 12 - S. We can then substitute this into equation 2 to yield the following:

25(12 - s) + 10s = 180

300 - 25s + 10s = 180

300 - 25s + 10s = 180

300 - 15s = 180

15s = 300 - 180

15s = 120

S = 120/15

S = 8

S = 8 , and R = 12 - S = 12 - 8 = 4

Answer:

The most number of layers he can afford is 2

Step-by-step explanation:

We automatically have a fee of 17 so we know we have 13 dollars remaining. Using this information, we know that one layer is 5 dollars which means we can get 2 layers which is equal to 10 dollars which turns our total fee to $27. Hope this helps!

Answer: 166.667 miles

Step-by-step explanation:

For the first company, the cost can represented by the equation: y=0.25m +50+15

Which is the same as y=0.25m +65

For the second company, the cost can represented by the equation:0.35m+40

m is the miles driven

To find at after how many miles they cost the same, I will set both equations equal to each other to solve for m

0.25m+65=0.35m+40

-0.25m -0.25m

65=0.15m+40

-40 -40

25=0.15m. Divide both sides by 0.15

166.667=m

So after 166.667 miles, the companies charge the same.

You can also round it again: 166.67 or 166.7 or 167

Answer:

42.5%

Step-by-step explanation:

First we have to complete the table. We know that there are forty part time students so sum(f)=n=40. So, for two courses frequency is 40-11-12=17.

The relative frequency is the proportion of respective frequency and the sum of frequency. So, the missing relative frequency for 1st course is 11/40=0.275.

The missing relative frequency can also be computed as by subtracting given relative frequencies from 1 as sum of relative frequencies is 1. So, 1-0.425-0.3=0.275.

The cumulative frequency of respective class is the sum of frequency of previous classes and frequency of respective class. The missing cumulative frequency is 11+17+12 or 28+12= 40.

So, the complete table is

# of Courses Frequency Relative Frequency Cumulative Frequency

1                        11                   0.275                    11

2                        17                  0.425                    28

3                         12                  0.3                        40

The percent of students takes exactly two courses=0.425*100=42.5%

Answer:

10 Hours

Step-by-step explanation:

I believe the question is saying they rode for 8 days and of those 8 days they rode the whole 24 hours, so by that logic:

8 days x 24 hours: 192 Hours

192/18 people = 10.66

10.66 ~ 10 Hours

Logarithmic Equations

The following equation is given:

Step-by-step explanation:

a function is when a number has one corresponding number (some say exponent or other words)

A relation may or may not represent a function

The relations that represent a function are: (a) first ordered pair and (c) the linear graph

For an ordered pair to be a function, each x values must not point to several y-values

For a graph to represent a function, it must pass the vertical line test.

Based on the above highlights, the relations that represent a function are:

Answer:

10^12.

Step-by-step explanation:

You need to solve 10^6 * 10^2 without using standard notation. As with variables, if you had x^6 * x^2 you would add the exponents. Replace x with 10. Your answer is 10^8. As a sidenote, only multiply exponents when raising a power to another power, e.g. (10^6)^2 = 10^12.

present age of charlie is  45 years

present age of priya is  25 years

Step-by-step explanation:

Let start from five years ago

Let at that age of Priya was x years

given that

Charlie was twice older than Priya

age of Charlie = 2x

_____________________________________________

present age of charlie = age 5 years ago + 5 years = 2x + 5

present age of priya = age of priya  5 years ago + 5 years x + 5 = x + 5

_________________________________________________

age of charlie 3 years from now = present age of charlie + 3 years

age of charlie 3 years from now =2x + 5 + 3 = 2x + 8

age of priya 3 years from now = present age of priya + 3 years

age of priya 3 years from now =x + 5 + 3 = x + 8

Given that

in 3 years the sum of their ages will be 76

thus

sum of their ages in 3 years from now = x + 8 + 2x + 8 = 76

=> 3x + 16 = 76

=> 3x = 76-16 = 60

=> x = 60/3 = 20

Thus,

present age of charlie =  2x + 5 = 2*20 + 5 = 45 years

present age of priya = x + 5 = 20 + 5 = 25 years

Answer:

Step-by-step explanation:

let the apprentice duration of work be x hours

so that the electrician worked (x+4)hours

53*(x+4)+22*x=624.50

opening the bracket we have

53x+212+22x=624.50

collect like terms we have

53x+22x+212=624.50

75x+212=624.50

75x=624.50-212

75x=412.5

divide both sides by 75 we have

x=412.5/75

x=5.5

The electrician worked a total of (x+4)

5.5+4=9.5 hours or 9hours 30min

given that the electrician earns $53 per hour

then,for the work he would make 53*9.5=$503.5

Answer: I think the answer is D

Step-by-step explanation:

Option - C is the correct option.

We have a statement - If a polygon has exactly 4 sides, it is a quadrilateral.

We have to write the contrapositive of this conditional statement.

A combination of the converse and the inverse is called Contrapositive of the Conditional statement. Contrapositive will replace if with then and vice - versa and after that both parts are negated.

According to the question, we have a statement -

If a polygon has exactly 4 sides, it is a quadrilateral.

Firstly, replace ' if ' with ' they ' and vice - versa. We get -

If a polygon is a quadrilateral, than it does have exactly four sides.

Now, negate it -

If a polygon is not a quadrilateral, it does not have exactly 4 sides.

Hence, Option C is correct.
