The result of the function f(x)=x+6 when x= -2,0 and 5 is

f(-2)= 4

f(0)= 6

f(5) = 11

The function  is f(x) = x+6

The function is an expression that shows the relationship between one variable and another variable.  One variable will be independent variable and another variable will be dependent variable.

The given function f(x) = x+6 when x =-2, 0 and 5. Here we have to substitute the values of x in the given function

f(x)  = x+6

f(-2) = -2+6

= 4

f(0) = 0+6

= 6

f(5) = 5+6

= 11

Hence, the result of the function f(x)=x+6 when x= -2,0 and 5 is

f(-2)= 4

f(0)= 6

find the angles of this​

Answers

Angles of ∠y is 45° and ∠x is 135°.

What are angles?

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.

Given Data

SRQ = 130°

∠R = 130°

As PR is the same line

So. angles of the line is 180°.

∠Y + ∠R = 180

∠y = 180 - 135

∠y = 45°

Now, PQ is the straight line

∠y +∠x = 180

∠x = 180-45

∠x = 135°

Angles of ∠y is 45° and ∠x is 135°.

At 1 hour, 3 hours and 6.5 hours she travels 36 miles, 108 miles and 234 miles respectively using the concept of average speed of an object.

As per the question statement, Clare covers a distance of 0 miles, 72 miles, 144 miles and 216 miles in 0 hours, 2 hours, 4 hours and 6 hours respectively.

We are supposed to find out the distance travelled by her in 1 hour, 3 hours and 6.5 hours.

We will use the concept of average speed of an object which is as follows

average speed = total distance divided by the total time taken

average speed = 216/6 = 36 miles per hour

Hence at 1 hour, distance = 1 * 36 = 36 miles

at 3 hours, distance = 3 * 36 =108 miles

at 6.5 hours, distance = 6.5 * 36 = 234 miles

two gears, A and B. are arranged so that the teeth of one gear is mesh with the teeth of another. Gear A turns clockwise and has 54 teeth. Gear B turns counterclockwise and has 36 teeth. If gear A makes 5.5 rotations, how many turns will gear B make?

Answers

The number of turns gear B will make is 8.25 turns

How to find the number of turns gear B will make

Given data

Gear A turns clockwise and has 54 teeth

Gear B turns counterclockwise and has 36 teeth

gear A makes 5.5 rotations

One of the gears is driving the other hence the distance covered by each of the gears is constant.

The distance is the product of the number of rotations and the number of teeth and this should be a constant

Therefore, let the number of rotations of gear B be x

54 teeth * 5.5 rotations = 36 teeth * x rotations

x rotations = ( 54 teeth * 5.5 rotations ) / 36 teeth

x rotations = 54/36 * 5.5

x rotations = 1.5 * 5.5

x rotations = 8.25

We can therefore say that gear B will make 8.25 rotations

Number cars sold 5 6 7 8 9 10
Salary 2750 3200 3650 4100 4550 5000

a. Is this linear? How do you know?
b. Suppose Mr. G thought he could sell 23 cars during one month. What would his total monthly pay be? Show your work!
c. If the gross pay is $6,800, how many cars were sold? Show your work!

Answers

The relation on the table of values is a linear model,

The total monthly pay is $10850 when he sells 23 cars in one monthThe number of cars is 14 if the gross pay is $6,800

How to determine if the relation is linear?

The table of values is given as

Number cars sold 5 6 7 8 9 10

Salary 2750 3200 3650 4100 4550 5000

On the table of values, we can see that:

As the number of cars increase by 1, the salary increases by 450

This means that the table has a constant rate of 450

Relations that have a constant rate are  linear relations

Hence, the table of values is a linear relation

The total monthly pay

In (a), we have

Slope, m = 450

A linear equation is represented as

y = m(x - x1) + y1

So, we have

y = 450(x - 5) + 2750

Evaluate

y = 450x + 500

When the number of cars is 23, we have

y = 450 x 23 + 500

Evaluate

y = 10850

Hence, the total monthly pay is $10850

The number of cars

Here, we have

y = 6800

This gives

450x + 500 = 6800

This gives

450x = 6300

Evaluate

x = 14

Hence, the number of cars is 14

What does probability mean in math?

Probability is a way to gauge how likely something is to happen. Many things are hard to predict with complete certainty. We can only forecast how likely an event is to occur using it, or how likely it is to occur.

The probability is typically defined as the proportion of positive outcomes to all outcomes in the sample space. Probability of an event P(E) = (Number of favourable outcomes) is how it is stated (Sample space).

based on the facts provided;

p(0) = p(w,w)

= 0.29² = 0.0841

p(1) = p(t, w+t) + p(w, t)

= 2p(w,t) +p(t,t) = 2·.29·.37 + .37² = 0.3515

p(2) = p(f, w+t+f) +p(w+t, f)

= 0.16(2(.29+.37)+.16) = 0.2368

p(3) = p(s, w+t+f+s) +p(w+t+f, s)

= 0.18(2(.29+.37+.16) +.18) = 0.3276

In summary, your pmf is ...

Here we have the elements:

a₃ = 0

a₄ = 6

a₅ = 12

a₆ = 18

So each term adds 6 to the previous one, so trivially the relation is of the form:

aₙ = aₙ₋₁ + 6

Now we need to find the first term.

We can rewrite the above equation as:

In mathematics, an inequality is a connection between two expressions and values that aren't equal to each other.

Rule 1: Once inequalities are linked, they can be crossed. As a result, if an is greater than b and b is higher than c, a will be greater than c as well.Rule 2: When you swap the values, this same sign also flips.Rule 3: An inequality could be either > or, but not both at the same time.

As per the given question;

The total budget of Salma is $75.

The flat cost is $55.

The cost per gigabytes is $5.

Let the number of gigabytes used be 'x'.

Then, the inequality becomes.

55 + 5x < 75

Subtracting 55 from both sides.

55 + 5x - 55 < 75  - 55

She employed her in meanest work of the house: she scoured the dishes, tables, etc., and scrubbed madam's chamber and those of misses, her daughters; she lay up in a sorry garret, upon a wretched straw bed, while her sisters lay in fine rooms, with floors all inlaid, upon beds of the very newest fashion, and where they had looking-glasses so large that they might see themselves at their full length from head to foot. The poor girl bore all patiently and dared not tell her father, who would have rattled her off; for his wife governed him entirely. When she had done her work she used to go into the chimney-corner and sit down among cinders and ashes, which made her commonly be called a cinder maid; but the youngest, who was not so rude and uncivil as the eldest, called her Cinderella. However, Cinderella, notwithstanding her mean apparel, was a hundred times handsomer than her sisters, though they were always dressed very richly.How does the author use juxtaposition in this excerpt to guide the reader's perspective on the characters? The characterization of Cinderella as lazy contrasts with her stepsisters' hardworking nature, which makes the reader question Cinderella's motives. The description of Cinderella's mother contrasts with the characterization of the stepmother, which makes the reader happy that Cinderella has a kinder caretaker. The mean and evil nature of the stepmother contrasts with the good nature of Cinderella, which makes the reader sympathize more strongly with the protagonist. The uncaring nature of Cinderella's father contrasts with Cinderella's kind and hardworking nature, which makes the reader dislike the father. fully describe the pathway that water flows through a plant?
