Step-by-step explanation:

The domain of the function is x < 2 and it is discontinuous at x = 2

The domain of a function is the range of input values to the function.

Given that the above function f(x) = √[(x² + 1)/(2 - x)]

The domain of the function is the range of values of x that make the denominator greater than zero

So, the domain is √(2 - x) ≥ 0

2 - x ≥ 0

2 ≥ x

x ≤ 2

So, the function is valid for x < 2 and discontinuous at x = 2 since at x = 2, √(2 - x) = √(2 - 2) = 0

So, we see that the function is valid for x < 2 and discontinuous at x = 2

So, the domain of the function is x < 2 and it is discontinuous at x = 2

The hypothesis is the phrase following the word if = " The hypothesis is: You have a driver's license."

The conclusion is the phrase following the word then = " The conclusion is: You are at least 16 years old."

A specific, verifiable prediction of what the researcher(s) believe the study's results will be is known as a hypothesis (plural: hypothese). It is stated at the outset of the investigation.

Most often, this entails speculating on a potential correlation between two variables: the independent variable (what the researcher modifies) and the dependent variable (what the research measures).

The null hypothesis and the alternative hypothesis (known as the experimental hypothesis when the technique of examination is an experiment) are traditionally written as two separate forms of the hypothesis in research.

The first five terms of a geometric sequence with first term -100 and common ratio 1/5 are  -100, -20, -4, -4/5, -4/25

The given parameters:

a₁ = -100, r = 1/5

r is the common ratio, hence, the given sequence is a geometric sequence.

In a geometric sequence, the formula for the nth term is given by:

      a(n) = a(1) . rⁿ⁻¹

We can also find the terms using recursive formula. The nth term of a geometric sequence is equal to the (n-1)th term times the common ratio, r. Mathematically,

      a(n) = a(n -1) . r

Let us start from n = 1

a(1) = -100  (given)

a(2) = a(1) . r = (-100) . 1/5 = -20

a(3) = a(2) . r = (-20) . 1/5 = -4

a(4) = a(3) . r = (-4) . 1/5 = -4/5

a(5) = a(4) . r = (-4/5) . 1/5 = -4/25

Therefore, the first five terms are  -100, -20, -4, -4/5, -4/25

The coordinates of the midpoint M are (-4,6)

Midpoint is the middle point of line segment. Measuring the distance between the two end points and divide the result by 2 this distance is known as midpoint of that line. Adding two end point of x and y and divide the sum by 2 we get coordinates of midpoint.

We can calculate the coordinates of midpoint by Midpoint formula

[tex]=\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}[/tex],

Endpoints of AB are A(-8,5) and B(0,7)

[tex](x_1,y_1)=(-8,5) and (y_1,y_2)=(0,7)[/tex]

Put the value of x and y in the above formula we get

All outcomes in a die are 1,2,3,4,5, and 6.

Even outcomes = 2,4, and 6

Odd outcomes = 1,3, and 5

Hence,

Total number of odd outcomes = 3

Total number of outcomes = 6

We know that,

Probability of an event = Number of possible outcomes of the event/ Total number of outcomes

A right triangle with a right angle and two sharp angles that are congruent to one another is known as an isosceles right triangle. A right triangle that is also isosceles is known as an isosceles triangle. It therefore has two sides that are identical and one right angle.

A right triangle with two equal-length legs is called an isosceles right triangle. The corresponding angles would also be congruent because the lengths of the two legs of the right triangle are equal. As a result, the two acute angles and two legs of an isosceles right triangle are congruent.

The equation of the line in slope-intercept form passing through the point (1 , -1) and parallel to y = (2/5)x - 3 is y = (2/5)x - 7/5.

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The slope-intercept form of the equation of a line is given by the formula:

y = mx + b

where m is the slope of the line

b is the y- intercept

If the line is parallel to y = (2/5)x - 3, then their slopes are equal.

y = (2/5)x - 3 : m = 2/5

m = 2/5

Substitute the values of the slope and the point to solve for the y-intercept, b.

y = mx + b

-1 = 2/5(1) + b

b = -7/5

Write the equation of the line by plugging in the value of the slope and y-intercept.

y = mx + b

y = (2/5)x - 7/5

According to the translation rule, The translation of the rectangle is (x, y) → (x – 3, y + 5). Thus option C is correct.

According to the statement

We have to find that the translation rule.

So, For this purpose, we know that the

Translation is refers to the movement of a shape from one point to a different, without altering its appearance.

From the given information:

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left.

With this in mind,

Once there's an upwards or downwards movement, there's a shift within the y coordinate

A move to the left or right movement, the x- coordinate is affected and moving left is negative

Hence,

y-coordinate is positive

x-coordinate is negative

Therefore, the rectangle translating 5 units up and three units to the left would be: (x, y) → (x – 3, y + 5)

So, According to the translation rule, The translation of the rectangle is (x, y) → (x – 3, y + 5). Thus option C is correct.
