E and f are supplementary. If m e = (9x-38) and m f = (2x+42) find m f

The value of f (1) is 5.

The value of f (-7) is - 35.

The value of f (y + 2) is (-y²- 5y + 1).

What is Function?

A relation between a set of inputs having one output each is called Function.

The function is given as;

⇒ f(x) = -x² - x + 7

Now, To find value of f (1), substitute the value of x = 1 in given function and then calculate as;

⇒ f(x) = -x² - x + 7

⇒ f (1) = - (1)² - 1 + 7

⇒ f (1) = - 1 - 1 + 7

⇒ f (1) = 5

Hence, The value of f (1) is 5.

To find value of f (-7), substitute the value of x = -7 in given function and then calculate as;

⇒ f(x) = -x² - x + 7

⇒ f(-7) = -(-7)² - (-7) + 7

⇒ f(-7) = -49 + 7 + 7

⇒ f(-7) = - 35

Hence, The value of f (-7) is - 35.

To find value of f (y + 2), substitute the value of x = y+2 in given function and then calculate as;

⇒ f(x) = -x² - x + 7

⇒ f(y + 2) = -(y + 2)² - (y + 2) + 7

⇒ f(y + 2) = - (y² + 4y + 4) - y - 2 + 7

⇒ f(y + 2) = - y² - 4y - 4 - y - 2 + 7

⇒ f(y + 2) = -  y² - 5y + 1

Hence, The value of f (y + 2) is (-y²- 5y + 1).

So, The value of f (1) is 5.

The value of f (-7) is - 35.

The value of f (y + 2) is (-y²- 5y + 1).

The simplification of the given expression using laws of Indices is :

[tex]\frac{y^{14}}{z^{14}}[/tex]

How to use Laws of Indices?

We want to simplify the expression y raised to the negative second power times z raised to the third power end quantity over quantity z raised to the negative fourth power times y raised to the fifth power end quantity all raised to the negative second power.

The above can be expressed as :

[(y⁻² * z³)/(z⁻⁴ * y⁵)]^(-2)

Collecting like terms and When two terms that are divided have the same base and different exponents, we keep the base and subtract the exponents, hence :

= [(y⁻² * z³)/(z⁻⁴ * y⁵)]²

= [(z⁻⁴ * y⁵)/(y⁻² * z³)]²

= [(z⁻⁴/z³) x (y⁵/y⁻²)]²

= [z^{-4-3} x y^{5+2}]²

= [z^{-7} x y^{7}]²

Then both numerator and denominator exponents multiply by 2, hence the equivalent expression is :

= [tex][\frac{y^{7}}{z^{7}}]^{2} = \frac{y^{14}}{z^{14}}[/tex]

The simplification of the given expression 2 √-24+6 is 9.8 i + 6.

Complex numbers are helpful in finding the square root of negative numbers.

A complex number is the sum of a real number and an imaginary number.

Given the expression,

2 √-24+6

Now,

2 √-24+6 = 2√(-1 × 24) + 6

⇒ 2 √(-1) × √24 + 6

Since √(-1) is an imaginary number and is denoted by "i".

So,

2 √(-1) × √24 + 6 = 2i × √24 + 6

⇒ 2√24 i + 6

⇒ √4 × √24 i + 6

⇒ √(4×24) i + 6

⇒ √96 i + 6

⇒ 9.8 i + 6

Hence "The simplification of the given expression 2 √-24+6 is 9.8 i + 6".

The distance between base of tree and swing set is 24 feet.

We are given the angle of depression and the vertical height. Joining the three points, which are top and base of tree and swing set forms a right angled triangle. The height of tree will be perpendicular of triangle and base will be the distance between base of tree and swing set.

The angle at the swing set will be equal to 30.26°, as alternate angles are equal.

So, the angle formed can be related with perpendicular and base by -

tan theta = perpendicular ÷ base

Keep the values in formula to find the value of base

Base = perpendicular ÷ tan theta

Base = 14 ÷ tan 30.26°

Base = 14 ÷ 0.5834

Step-by-step explanation

There are 6 sides on a standard die (1, 2, 3, 4, 5, 6). Out of these numbers, only 3 and 6 are divisible by 3. Therefore, 2/6 numbers would be divisible by 3. As the die is rolled 4 times, we multiply 2/6 4 times - (2/6)(2/6)(2/6)(2/6) to get 1/81. The probability that the die shows a number divisible by three all four times is 1/81. Hope that helps!

The elephant can move 53.2 meters if it is charged for 1 minute.

Given,

The time that the elephant charged = 15 seconds

The distance that the elephant can travel by this charge = 13.3 meters

We have to find the distance moved by the elephant if it is charged for 1 minute:

That is,

15 seconds = 13.3 meters

Then,

1 minute (60 seconds) = x

Therefore;

15 × x = 13.3 × 60

x = (13.3 x 60) / 15

x = 798 / 15

x = 53.2

for the equation - 7 + 4 u = - 35, we get the value of u after solving it as - 7.

We are given the equation:

- 7 + 4 u = - 35

We need to solve the equation for u.

- 7 + 4 u = - 35

Add 7 to both the sides, we get that:

- 7 + 4 u + 7 = - 35 + 7
4 u = - 28

Divide both the sides by 4, we get that:

4 u / 4 = - 28 / 4

u = - 7

Therefore, for the equation - 7 + 4 u = - 35, we get the value of u after solving it as - 7.

Answer: C.

Step-by-step explanation:

The equation of this straight line is y = 50x + 100.

A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.

In order to determine the equation from this graph of a linear equation, we would find the slope of the straight line by using this formula as follows:

[tex]Slope,\;m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope,\;m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

Slope, m = 100/2

Slope, m = 50.

Mathematically, the standard form of the equation of a straight line is given by;

y = mx + c

Where:

At point (4, 300), we have:

y = mx + c

300 = 50(4) + c

300 = 200 + c

c = 300 - 200

c = 100.

Therefore, the equation of this straight line is y = 50x + 100.

On reflecting f(x) = 9x in the x-axis and vertical compression by a factor of 1/3 we get the transformation g(x) where, g(x) = -3x

Transformation of the function means that the curve representing the graph either moves to the left or right or up or down or expansion , compression or reflection of graph happens.

Rules for reflection over x axis  :  for an curve y = f(x) , replace y by -y and keep x as it is, we get -y = f(x) or y = - f(x)

Rules for vertical compression by a factor α : y becomes αy .If f(x) is compressed by a factor of 1/2 the the transformations becomes 1/2(f(x))

Given function is f(x) = 9x

When we reflect f(x) over x axis then the transformations becomes some h(x) where h(x) = -f(x) =-9x

Now we want to vertically compress it by a factor of 1/3 , then this transformation will become g(x) = 1/3(h(x)) = 1/3(-9x) =(-9/3)x =-3x

So let's take a = -19 as there is a decrease in the percentage and b = 15 as there is an increase.

So we get a single percentage = -19 + 15 - (19×15)/ 100

                                                    = - 4 -2.85
