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 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

That is, the elephant can move 53.2 meters if it is charged for 1 minute.

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.

The length of the segment when J is between H and K will be HJ = 21 and JK = 12.

From the information given, J is between H and K and we want to use the segment addition Postulate to solve for x.

It should be noted that:

HJ=4x+9,

Jk=3x+3,

HK=33

Therefore, we will equate the values. This will be:

4x + 9 + 3x + 3 = 33

7x + 12 = 33

Collect like terms

7x = 33 - 12

7x = 21

Divide

x = 21 / 7

x = 3

HJ=4x+9, = 4(3) + 9 = 21

Jk=3x+3 = 3(3) + 3 = 12

Therefore, the length of the segment when J is between H and K will be HJ = 21 and JK = 12.

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, 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

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 equation given is
