The graph of y = f(x) is shown below. What are all of the real solutions of f(x)
= 0?

Answers

Answer:

x = -8, 0 and 6

Step-by-step explanation:

Graphed function in the picture,

y = f(x)

Solutions of a function are defined by the points on x-axis where the graph intersects or touches.

In the given graph, curve of the function touches the x-axis at x = -8 and crosses the x-axis at x = 0, 6

Therefore, real solutions of the function 'f' will be x = -8, 0 and 6.

Answers

Answer:

[tex]-\frac{21}{10}[/tex] or [tex]-2.1[/tex] (they're the same)

Step-by-step explanation:

Simplify: [tex]-\frac{9}{6} + (-\frac{3}{5}) = -\frac{9}{6} - \frac{3}{5}[/tex]  Find a common denominator. The LCM of 6 and 5 is 30, so multiply the numerator and the denominator by the same thing: 6 × 5 = 30, -9 × 5 = -45, 5 × 6 = 30, 3 × 6 = 18Write the new fractions: [tex]-\frac{45}{30} - \frac{18}{30}[/tex]  Subtract: -45/30 - 18/30 = [tex]-\frac{63}{30} = -\frac{21}{10}[/tex]

Answers

Solution :

7658 - 7000 = 658 - blank

658 = 658

So here, blank is 0.

547 - 7000 = 658 - blank

-7111 = 658 - blank

Blank = 7769

14 - 7000 = 658 - blank

- 6986 = 658 - blank

Blank = 7644

They all have the passive word, "Visited," so that makes everything a bit more complicated. I can see why you asked the question. I'd go with C. Unless it's a trick question and you're supposed to see that or something.

An airline records data on several variables for each of its flights, model of plane, amount of fuel used, time in flight,
number of passengers, and whether the flight arrived on time. The number and type of variables recorded are
1 categorical, 4 quantitative (1 discrete, 3 continuous)
O 3 categorical, 2 quantitative (1 discrete, 1 continuous)
O 1 categorical, 4 quantitative (2 discrete, 2 continuous)
2 categorical, 3 quantitative (1 discrete, 2 continuous)
O 2 categorical, 3 quantitative (2 discrete, 1 continuous)

Answers

Answer:

The correct option is;

2 categorical, 3 quantitative (1 discrete, 2 continuous)

Step-by-step explanation:

A categorical variable which is otherwise known as a nominal variable is one which can be qualified as belonging to one class or category of objects or the other, depending on its attributes, and not based on order of the classes.

Therefore;

1) The model of the plane, and 2) whether the flight arrived on time, are categorical variable

A quantitative variable is a variable that indicates measurement and therefore, indicates the numerical magnitude of a measurement.

Therefore;

1) Amount of fuel used, 2) Time in flight, 3) The number of passengers are quantitative variables

Quantitative variables can be either discrete or continuous

A discrete quantitative variable is one that has a finite number of possible values or which may have an infinite but countable number of values

Therefore;

1) The number of passengers which is countable and exact is a discrete quantitative variable

A continuous variable is one whose exact or accurate value range is infinite or a variable with a limitless value set such as the range of values between two real numbers

Therefore;

1) Amount of fuel used and 2) Time of flight are continuous quantitative variables.

Answer:

[tex] \boxed{ \bold {\huge{ \text{30 \: cm}}}}[/tex]

Step-by-step explanation:

[tex] \star{ \sf{ \underline{ \: \: Given}}}[/tex]

Area of a rectangle ( A ) = 36 cm²

Width of a rectangle ( w ) = 3 cm

[tex] \star{ \sf{ \underline{ \: \: To \: Find}}}[/tex] :

Perimeter of a rectangle ( P ) = ?

First, finding the length of a rectangle ( l ) :

[tex] \boxed{\text{area \: of \: a \: rectangle = length ∗ width}}[/tex]

[tex] \dashrightarrow{ \sf{36 = length \times 3}}[/tex]

[tex] \dashrightarrow{ \sf{36 = 3 \: length}}[/tex]

[tex] \dashrightarrow{ \sf{3 \: length = 36}}[/tex]

[tex] \dashrightarrow{ \sf{ \frac{3 \: length}{3} = \frac{36}{3} }}[/tex]

[tex] \dashrightarrow{ \sf{length = 12 \: cm}}[/tex]

Length of a rectangle = 12 cm

Now, finding the perimeter of a rectangle having length of 12 cm and width of 3 cm

[tex] \boxed{ \text{perimeter \: of \: a \: rectangle = 2(l + w)}}[/tex]

[tex] { \sf{perimeter \: of \: a \: rectangle = 2(12 + 3)}}[/tex]

[tex] \dashrightarrow{ \sf{perimeter \: of \: rectangle = 2 \times 15}}[/tex]

[tex] \dashrightarrow{ \sf{perimeter \: of \: rectangle = 30 \: cm}}[/tex]

Perimeter of a rectangle = 30 cm
