If the coordinate is reflected over the y-axis, the resulting coordinates will be (1, 2).

Images that are reflected are mirror images of each other. For instance, given the coordinate points (x, y), if it is reflected across the y-axis, then the result of the expression is (-x, y).

Given the coordinate point (-1, 2), if the coordinate is reflected over the y-axis, the resulting coordinates will be (1, 2).

Note that the x-coordinate point is negated if the coordinate is reflected over the y-axis.

If we assume that I = E(R + r), then I/I = R/E + r/E​.

The inverse of a value of a number is known as the reciprocal of the number. The reciprocal can be found out by replacing the numerator with the denominator and vice versa. For example, reciprocal of a number x will be 1/x and vice versa.

Here, we are given that I = E/(R + r)

Taking reciprocals of both sides we get-

Reciprocal of I will be- 1/I

Reciprocal of E/(R + r) will be- (R + r)/ E

Thus,

1/I = (R + r)/ E

Simplifying the equation further, we get-

1/I = R/E + r/E

Hence, proved

Complex fraction 4²/₃ + 1/3 – 4¹/₃ = 2/3

A fraction defined as the part of the whole thing. For example, a pizza is divided into four equal pieces, then each piece is represented by ¼. Fractions help to distribute and judge the numbers easily and make the calculation faster.

Some steps to solve a fraction -

Step 1: Write the factors of numerator and denominator.

Step 2: Determine the highest common factor of numerator and denominator.

Step 3: Divide the numerator and denominator by their highest common factor (HCF). The fraction so obtained is in the simplest form.

For example -

If a sports fan believes that, the probability of the red team winning is 0.35 and that of the blue team winning is 0.40, then the fan expects the red team to win 9 matches less than the blue team in a season of 180 games.

As per the question statement, based on the records for the past several​ seasons, a sports fan believes that, the probability of the red team winning is 0.35 and that of the blue team winning is 0.40.

We are required to calculate the number of games, the fan expects the red team to win, lesser than the blue team in a season of 180 games.

As per the probability record, maximum number of games, the fan believes that the blue team can win all over the season of 180 games = [tex](0.40*180)=(\frac{40}{100}*180)=(4*18)=72.\\[/tex]

Similarly, maximum number of games, the fan believes that the red team can win all over the season of 180 games = [tex](0.35*180)=(\frac{35}{100}*180)=(7*9)=63.\\[/tex]

Step-by-step explanation:

We need to know the relation between height, time to solve this problem. The time taken by the object to be 6 feet above the valley floor is 25 seconds.

The distance an object falls is proportional to the time it took to fall because of gravitational force. Here we have been given an equation that shows us the relation between height of the object and the time taken to reach that height. We know that the initial height of the object is 406 feet, if we substitute the initial height in the equation we get time to be zero which shows us that this is the initial height. We need to find out the time taken by the object to be 6 feet above the valley floor.

h= -16t+406

6=-16t+406

-400=-16t

t=400/16=25 seconds

Therefore the time taken by the object to be at a height 6 feet above the valley floor is 25 seconds.

Answer: 1/10 of a pound

Step-by-step explanation:

The total weight was 7/10 of a pound. Cutting the fudge into 7 pieces implies dividing the fudge by 7.

7 is the same as 7/1.

When dividing fractions, we can multiply by the reciprocal. Essentially, we just flip the second number.

[tex]\frac{7}{10}/7 =\frac{7}{10} / \frac{7}{1} =\frac{7}{10} *\frac{1}{7}[/tex]

We can multiply this out to 7/70 and then simplify to 1/10,

or we could first cross simplify by dividing the 7s out of the numerator and denominator before multiplying. Either way, your answer ends up being 1/10 of a pound.

Step-by-step explanation:

Using Descartes's Rule of Signs:

There are four positive real zeros P can have.

There are zero negative real zeros P can have.

Descartes' rule of sign is used to determine the number of positive and negative real zeros of a polynomial function.

We have,

P(x) = 2[tex]x^{4}[/tex] - 7x³ + x² - 18x + 3

We have to look at the sign of the coefficient

Here,

  2[tex]x^{4}[/tex] - 7x³  +  x²  -  18x + 3

(+)---(-)(-)---(+)(+)--(-)(-)---(+)

There are 4 variations so there are 4 positive real zeroes.

For finding negative real zeroes we Put x = -x.

P(-x) =  2[tex]x^{4}[/tex] + 7x³ + x² + 18x + 3

   2[tex]x^{4}[/tex]  +  7x³  +  x²  +  18x  +  3

(+)---(+)(+)----(+)(+)--(+)(+)-- --(+)

There are no variations so there are zero negative real zeroes.

Thus,

a) Using Descartes's Rule of Signs, we know that there are four positive real zeros P can have.

b) Using Descartes's Rule of Signs, we know that there are zero negative real zeros P can have.

The  slope of the line y-3= 4(x+8) is  4 and (-8, 30 is a point on line y - 3 = 4(x + 8).

According to the given question.

We have a equation of a line y-3= 4(x+8).

Here, we have to find the slope of a line y-3= 4(x+8) and a point on the line.

Since we know that, the equation of a lines through a point (x1, y1) is given by y - y1  = m(x - x1), where m is the slope of the line.

And the equation of slope intercept form for a line is y = mx + c.

So, compare the given equation of line y-3= 4(x+8) with the standard equation of line y - y1  = m(x - x1)  which passes through the point (x1, y1), we get

point ( -8, 3) on line y-3= 4(x+8).

Now, the slope intercept form of the line y-3= 4(x+8) is

y - 3 = 4x + 32

⇒ y = 4x + 32 + 3

⇒ y = 4x + 35

Thereofore, the slope of the line y-3= 4(x+8) is  4.

Hence, the  slope of the line y-3= 4(x+8) is  4 and (-8, 30 is a point on line y - 3 = 4(x + 8).

Answer:

Function 3 is less steep.

Step-by-step explanation:

The steepness of a linear function is determined by its coefficient of x.

Since the coefficient of x in [tex]f_3(x)[/tex], 0.5, is smaller than that of [tex]f_1(x)[/tex], 2, function 3 is less steep than function 1.

Significance of the coefficient of x

We can think of the function as an equation of a line in the slope-intercept form. That is, y= mx +c, where m is the slope and c is the y-intercept.

Steepness and value of x

The larger the numerical value of m, the steeper the line is.

Significance of the sign of x

The sign (positive or negative) of m tells us the direction in which the line is sloping towards. A positive m value gives us a line sloping upwards from left to right, while a negative m value gives us a line that is sloping downwards from left to right.
