Work out the total amount of money tom earned on monday

Answer:

10 minutes

Step-by-step explanation:

if 70 words = 1minute

862 words will be 862÷70=12.31 minutes

1,562 words will be 1562÷70=22.31 minutes

time needed to finish will be 22.31-12.31= 10 minutes

So the total time needed to finish will be 10 minutes

I don't see any statements either.

anyway, the only thing that can be said about the 2 lines is that they are crossing each other at one point.

the lines are not parallel, they are not perpendicular (90° to each other), they are not identical.

nothing can be said about a specific point on the line of intercepts with the x- and y-axis.

they are also not parallel and not perpendicular to any of the x- or y-axis.

The function operation ( f + g )( x ) in the functions f( x ) = x² + 2x and g( x ) = 4x² - 3 is 5x² + 2x  - 3.

A function is simply a relationship that maps one input to one output.

Given the data in the question;

First, replace the function designators in f + g with actual functions.

( f + g )( x ) = ( f )(x) + ( g )( x )

( f + g )( x ) = ( x² + 2x ) + ( 4x² - 3 )

Remove the parenthesis

( f + g )( x ) = x² + 2x + 4x² - 3

Collect and add like terms

( f + g )( x ) = x² + 4x² + 2x  - 3

( f + g )( x ) = 5x² + 2x  - 3

Therefore, the function operation ( f + g )( x ) is 5x² + 2x  - 3.

Answer:

The first questions unknown equals

[tex] \frac{3025}{49} [/tex]

The second question is unclear. I assume it is to simplify if that is the case the answer will be.

[tex] \frac{1}{2} [/tex]

Step-by-step explanation:

First Question I made ?=x for simplicity.

[tex]7 \sqrt{x} = 55[/tex]

then I divide both sides by 7

[tex] \sqrt{x} = \frac{55}{7} [/tex]

then I square both sides

[tex]x = \frac{3025}{49} [/tex]

Question 2

I simplified by dividing both the denominator and the numerator by their HCF (highest common factor) which is 5

[tex] \frac{5 \div 5}{10 \div 5} [/tex]

which equals

[tex] \frac{1}{2} [/tex]

Answer:

[tex]\textsf{1.} \quad 7\sqrt{\dfrac{3025}{49}}=55[/tex]

[tex]\textsf{2.} \quad \dfrac{5}{10}=\dfrac{1}{2}[/tex]

Step-by-step explanation:

Let x be the unknown number:

[tex]\implies 7\sqrt{x}=55[/tex]

Divide both sides of the equation by 7:

[tex]\implies \dfrac{7 \sqrt{x}}{7}=\dfrac{55}{7}[/tex]

[tex]\implies \sqrt{x}=\dfrac{55}{7}[/tex]

Square both sides of the equation:

[tex]\implies \left(\sqrt{x}\right)^2=\left(\dfrac{55}{7}\right)^2[/tex]

[tex]\implies x=\dfrac{55^2}{7^2}[/tex]

[tex]\implies x=\dfrac{3025}{49}[/tex]

Divide the numerator and the denominator by the highest common factor:

[tex]\implies \dfrac{5 \div 5}{10 \div 5}=\dfrac{1}{2}[/tex]

Answer: See explanation

Step-by-step explanation:

For questions 1 - 4, it's asking you to plug in numbers into the original functions.

1. f(-2): You would plug -2 into f(x) = 2x^2 - 3x, getting

2(-2)^2 - 3(-2)

2(4) - (-6)

8 + 6 = 14

f(-2) = 14

2. f(x) - g(x): You're basically just subtracting the two functions

(2x^2 - 3x) - (2 - 5x)

2x^2 - 3x - 2 + 5x

Combine like terms

2x^2 + 2x - 2

3. You're multiplying them so (2x^2 - 3x)(2 - 5x)

4. f(g(x)): It's like f(-2), but instead of -2, you plug in the function of g(x)

So in 2x^2 - 3x, x would equal 2 - 5x:

2(2 - 5x)^2 - 3(2 - 5x)

And then simplify that.

For questions 5 - 6, it's asking for shifting from the parent function. Parent function is always f(x) or g(x) or whatever variable it is.

5. f(x - 8) + 9: The 9 is the y value shift, meaning the parent function is shifted up 9 units. For -8, think of what x needs to be for (x - 8) to be 0. If that number is positive, function shifts right; if negative, shift left. In this case, x needs to be 8 in order for (x - 8) to be 0. Therefore, f(x) is shifted right 8 units.

6. -3f(x) - 2: From the previous question, we now know that -2 means f(x) is shifted down 2 units. When you have 3f(x), you're multiplying the entire function by 3, so it's called a vertical stretch of 3. The negative means it's reflected over the x-axis since the y value is the opposite of what it used to be.

a)

If the triangles are similar, the corresponding sides vary on the same proportion, so the ratios between the corresponding sides are equal.

For

To solve for x you have to multiply both sides of the expression by 20

b)

Following the same logic, the ratio between x and 20 is the same as the ratio between 6 and 8

6/8 can be simplifies as 3/4. Then multiply both sides by 20 to determine the value of x.

As mentioned above, when two triangles are similar, the corresponding sides are always in the same ratio, that is why the results in a and b are the same.

The sequence's numbers are all multiples of 30. Every number can be divided by 30.

If two integers are divided equally, leaving no remainder, then we say that one integer divides the other (we sometimes say, "with no remainder," but that is not technically correct). Mathematicians express this more explicitly as follows: If a and b are integers (with a not zero), then a divides b if c is an integer such that b = ac. Sequence: 1 51, 2 52,....., n 5n,....n 5n=n(n 4 1)=n(n1)(n1)(n+1)(n 2 +1)

Answer:

it depends on the question

Usually if it a triangle with 2 angles and an x

you will add the 2 angles and rearrange to give the answer

Step-by-step explanation:

Hope this helps!!!

Answer:

A right triangle has one angle measuring 90 degrees. The side opposite this angle is known as the hypotenuse (another name for the longest side). The length of the hypotenuse can be discovered using Pythagoras's theorem, but to discover the other two sides, sine and cosine must be used. These are trigonometric functions of an angle.

In the diagram below, one of the angles is represented by the Greek letter θ. (pronounced "the - ta"). Side a is known as the "opposite" side and side b is called the "adjacent" side because of their positions relative to the angle θ.

The vertical lines "||" around the words below mean "length of."

So sine, cosine and tangent are defined as follows:

Step-by-step explanation:

So sine, cosine and tangent are defined as follows:

sine θ = |opposite side| / |hypotenuse|

cosine θ = |adjacent side| / |hypotenuse|

A graph of the linear function (y = 2x - 3) which matches the answer is shown in the image attached below.

A graph refers a type of chart that's commonly used for the graphical representation of data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

Generally speaking, the graph of any proportional relationship such as a linear function is characterized by a straight line with the points passing through the origin (0, 0) because as the values on the x-axis decreases or increases, the values on the y-axis decreases or increases simultaneously as shown in the image attached below.

In conclusion, a graph representing the given linear function shows a proportional relationship between the value of x and y.

For 4 years, Deirdre paid $2 in dues.

Deirdre paid each year for three years = 3 × 10 = 30.

Let's consider x as the number of years,

As Deirdre paid $2 for x years the value she paid will be 2x,

Deirdre paid = $2x (in x years)

Deirdre has paid $10 for three years each, a total of $38 in dues. So the final equation will be,

38 = 30 + 2x

38 - 30 = 2x

8 = 2x

x = 4

Thus, Deirdre has paid $2 in dues for 4 years.

After using Arithmetic we'll get - Total of her paycheck $250

What is Arithmetic ?

The study of the characteristics of the standard operations on numbers, including addition, subtraction, multiplication, division, exponentiation, and root extraction, constitutes the fundamental subject of arithmetic. Giuseppe Peano, an Italian mathematician, formalised arithmetic in the 19th century with the help of his Peano axioms, which are still crucial to the modern study of mathematical logic. There are only a few artefacts from the early history of mathematics that may have shown how addition and subtraction were first thought of. The best-known of them is the disputedly interpreted Ishango bone from central Africa, which dates from between 20,000 and 18,000 BC.
