?
The ordered pair which describes the location of M''M" is (4, -4).
What is a reflection?In Geometry, a reflection over the y-axis is given by this transformation rule (x, y) → (-x, y). This ultimately implies that, a reflection over the y-axis would maintain the same y-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.
By applying a reflection over the y-axis to the coordinates of the image coordinates include the following:
(x, y) → (-x, y)
Coordinate M = (-4, 4) → Coordinate M' = (-(-4), 4) = (4, 4).
Next, we would apply a reflection over the x-axis to the above coordinates as follows:
(x, y) → (x, -y)
Coordinate M' = (4, 4) → Coordinate M" = (4, -(4)) = (4, -4).

Why earthquakes with the greatest magnitude do not always cause the highest number of deaths?.
The earthquakes with the greatest magnitude do not always cause the highest number of death because other factors like area ( ground, water , sand etc.), soil structure, buliding constutor material etc. also affect the earthquake intensity.
The biggest earthquakes are not necessarily the most devastating ones. But other factors are also involved here. In areas of water-saturated sand, shaking loosens the sand particles from each other, causing them to "float" on the water and turn into quicksand. Sand at rest is still and hard, but when shaken it forms liquid mud. Buildings and other structures built on such sand simply sink and collapse. Other types of soil structures and terrain can amplify and resonate seismic waves, potentially causing more damage. Of course, if an earthquake occurs at sea, it can create a devastating tsunami. Also, certain structures and buildings are less susceptible to vibration than others due to how they are constructed and the materials used. For example, a large magnitude 9.0 earthquake might cause minor damage due to its remote location. But if 6.0 occurs in an underdeveloped and densely populated area, it could kill thousands.
The more people there are, the more people die. For example, the 2001 earthquake in India occurred in a densely populated area.

Can a negative number be an exponential function?.
Yes, it is possible for a negative number to be an exponential function.
The number of times a number is multiplied by itself is indicated by the positive exponent, as we are aware. In contrast, the negative exponent indicates how many times the base number must be divided. The negative exponent, in other words, indicates how many times the reciprocal of the base must be multiplied. 3-2 is a prime example of a negative exponent.Two negative exponents can be multiplied together in the same way as two numbers. Since we are aware that negative exponents can be reduced to fractions, simplifying negative exponents is simple. Converting the negative exponents to their fractional form is the first step in multiplying negative exponents, after which the procedure is the same as multiplying two fractional numbers.

1/6 of the whole garden is planted in cucumber.
What is cucumber ?
Cucumber is a type of vegetable that belongs to the cucurbit family, which also includes melons, squash and gourds. They are typically long, cylindrical in shape, and have a green skin that is typically eaten raw.
The proportion of the garden planted in cucumber is 1/3 of the vegetable part of the garden. To find out what proportion of the entire garden is planted in cucumber, we can use this proportion and multiply it by the proportion of the garden that is planted in vegetables.
Half of the garden is planted in vegetables, so the proportion of the garden planted in vegetables is 1/2.
1/3 of the vegetable part of the garden is planted in cucumber, so the proportion of the garden planted in cucumber is ,
(1/2) x (1/3) = 1/6
So, 1/6 of the whole garden is planted in cucumber.

What is the slope of a line whose equation is 3x 2y 8?.
The slope of the given equation is -3/2.
The equation of a line in the form 3x + 2y = 8 is not in the standard form of a linear equation, also known as slope-intercept form. In order to find the slope of the line, we need to express the equation in the form y = mx + b, where m is the slope of the line and b is the y-intercept.
To do this, we can start by isolating y on one side of the equation. We can subtract 8 from both sides, resulting in 3x + 2y -8 = 0.
Next, we can divide both sides by 2, which gives us (3/2)x + y - 4 = 0. This is the equation in the slope-intercept form.
The slope of the line is represented by the coefficient of x, which in this case is (-3/2). It tells us that for every 1 unit increase in x, the value of y will decrease by 3/2 units.

Two torage hed are to have the ame area. One i quare and one i rectangular. The rectangular hed i 3 meter wide and 12 meter long
By using the area of the square formula, it can be concluded that the side of the square shed is 6 meters.
The area of a square or a rectangle can be defined as the number of square units needed to fill it.
Area of a Square = side × side = side²
Area of a rectangle = width x length
Area of the square = area of the rectangle
Rectangle width = 3 meter
Rectangle length = 12 meter
To find the side of the square shed, we can do the following:
Area of the square = Area of the rectangle
side² = width x length
= 3 x 12
= 36
side = √36
= 6
Thus the side of the square shed is 6 meters.

How do you identify the horizontal asymptote of a graph?.
The horizontal asymptote of the graph is the horizontal line y = b and the graph approaches a straight line as the input approaches ∞ or −∞.
Horizontal Asymptote: As x moves towards infinity or -infinity, the curve approaches a constant value b, called a horizontal asymptote with equal numerator and denominator. The following are used to determine the horizontal asymptotes:
If the degree of numerator and denominator polynomials are equal, then the horizontal asymptotes is obtained by dividing the highest degree cofficientes.If the numerator degree is less than the denominator degree, the horizontal asymptote is y = 0.If the numerator degree is greater than the denominator degree, there is no horizontal asymptote.For example, function f(x) = 2x / (x - 3) and we have to determine the horizontal asymptotes. As we see the degree of polynomials both in numerator and denominator is equal. So, horizontal asymptotes is equal to number which is obtained by dividing the hightest degree coefficients i.e., 2/1 = 2. Thus, the function has only one horizontal asymptote which is y = 2.
