Answer:

In the interval (-∞, -5)

Step-by-step explanation:

Average rate of change of any graph is represented by the slope of the function in the given interval.

Rate of change =

= change in the y-coordinates

= change in the x-coordinates

If  = 0, then the rate of change will be zero in that interval

From the graph attached,

From x = -∞ to x = -5, we find a flat line, showing

Therefore, average rate of change of h(x) in the interval (-∞, -5) is zero

The solution of the given linera equation in one variable 12=2-k is at k = 10.

According to the given question.

We have a linear equation in one variable 12 = 2 - k.

As we know that, linear equation in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

Therefore, the solution of the linear equation in one variable 12 = 2 - k is given by

12 = 2 - k

⇒ 12 - 2 = -k         (subtracting 2 from both the sides)

⇒ 10 = -k

⇒ k = 10  

Hence, the solution of the given linera equation in one variable 12=2-k is at k = 10.

Yes, the product of an integer and a natural number will always be an integer.

         A natural number refers to a whole number that does not have any kind of fraction or decimal. Some examples of natural numbers are 1, 2, 3, 4, and so on. Zero is not a natural number.

        Integers refer to all numbers that can be positive and negative. It should not have a fractional part or a decimal part in the number. Integers can be depicted by the positive or the negative sign. Zero is an integer.

       Whenever we are multiplying a natural number with an integer, we are ultimately getting the result as a positive number, negative number, or zero. Thus, it will become an integer.

       Example 1: We can take the natural number 10 and the integer -5. Its product will be -50. Thus, it is an integer.

The orthocenter is the point where a triangle's three altitudes intersect, and the centroid is the point where the three medians intersect.

The coordinates of the orthocenter of Δ RST is (–4, –4).

An orthocenter of a triangle is the point at which altitudes drawn perpendicular from the vertex to the opposite sides of a triangle intersect. A triangle typically has three altitudes, and the intersection of all three altitudes is known as the orthocenter.

The orthocenter is the point where a triangle's three altitudes intersect, and the centroid is the point where the three medians intersect.

The slope of RS is (5-8)/(-1+4)  or –1. So, the slope of the altitude, which is perpendicular to RS is 1.

Now, the equation of the altitude from T to RS is:

y - 5 = 1(x - 5)

y  = x

Use the same way to find the equation of the altitude from R to ST. That is,

Y - 8 = -1/0 (X + 4 ) or x = -4

x = -4 and y = -4

Solve the equations to find the intersection point of the altitudes. So, the coordinates of the orthocenter of Δ RST is (–4, –4).

Using translation concepts, the coordinates of G after it is ROTATED 90 DEGREES CLOCKWISE are given by: (3,4).

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x). Examples are shift left, shift right, shift down, shift up, vertical stretching, horizontal stretching, vertical compression, horizontal compression, reflection over the x-axis, reflection over the y-axis, and rotations by a determined amount(in degrees). All these translations have predetermined rules that we apply to the figures.

The rule for a 90º clockwise rotation is given by:

(x,y) -> (y, -x).

From the figure given for the problem, the coordinates of G are given as follows:

G(-4,3).

Applying the rule, we have that:

(-4,3) -> (3, 4), as y = 3, -x = -(-4) = 4.
