The range of the exponential function y based on its equation and the context of the problem is; 0 < y ≤ 45529

The range of a function is the set that contains all possible output values for the function.

In this question, the function is given as: y = 45,529(0.78)^x.

It is an exponential function with initial value 45,529 and rate of change  of 0.78.

Now, it should be noted that exponential functions that are not shifted down, such as this one, are never negative nor zero. Thus, the range also has the restriction y > 0, and is given by:

By using the concepts of line segment and collinearity of line segments, the numerical length of the line segment JK within the line segment IK is 21 units.

In this problem we find two collinear line segments IJ and JK, two line segments are collinear if they are contained by the same line. The mathematical expression that represents the two collinear line segments are shown below:

IJ + JK = IK

If we know that JK = x + 6, IJ = 9 and IK = 2 · x, then the numerical length of JK is:

9 + (x + 6) = 2 · x

x + 15 = 2 · x

15 = 2 · x - x

15 = x

x = 15

JK = x + 6

JK = 15 + 6

Ratio :

A ratio can be defined as the relationship or comparison between two numbers of the same unit to check how bigger is one number than the other one. For example, if the number of marks scored in a test is 7 out of 10, then the ratio of marks obtained to the total number of marks is written as 7:10.

Total Ivan and Tanya share = £150

Ivan and Tanya share in the ratio of 4:1 respectively.

Let 4x be the money got by Ivan and x be the money got by Tanya.

Then, according to the question, we have

4x+x= 150

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

The graph of the function f(x) = x, as an illustration is attached

The transformation of linear functions are:

Horizontal shifts;

f(x + h); A shift of h units left

f(x - h); A shift of h units right

Vertical shifts;

f(x) + m; A shift of m units up

f(x) - m; A shift of m units down

Whereby the y-intercept of f(x) is 0, we have;

Let f(x) = x, therefore;

g(x) = f(x) + 3

      = x + 3

The graph has to be shifted 3 places up to get g(x), therefore;

Step-by-step explanation:

the area of any triangle is

baseline × height / 2

so, in our case

12 × height / 2 = 48

6 × height = 48

height = 48/6 = 8 units

m with the height and half of the baseline creates a right-angled triangle. and we can use Pythagoras to get m.

c² = a² + b²

c is the Hypotenuse (the side opposite of the 90° angle), which is m for this right-angled triangle.

a and b are the legs, which are in our case the height of the main triangle and half of the baseline of the main triangle.

so we get

m² = 8² + (12/2)² = 8² + 6² = 64 + 36 = 100

m = 10 units

The new mean after adding a 6-inch high platform is 73 inches, while the median changes from 66 inches to 72 inches.

The mean refers to the average of a data set and is the result of the sum of the values of the data set divided by the number of items.

The median is the middle value in the data set when arranged in an ascending or descending order.

Answer:

AB and CD are congruent.

Step-by-step explanation:

Given points:

After plotting the given points (see attachment), we can easily determine that AB is 7 units and CD is 7 units.  Therefore, AB and CD are congruent.

Alternatively, as points A and B share the same x-coordinate, the length of AB is the difference between the y-coordinates:

⇒ AB = 8 - 1 = 7 units

Similarly, as points C and D share the same y-coordinate, the length of CD is the difference between the x-coordinates:

⇒ CD = 5 - (-2) = 7 units

Finally, we can prove that AB and CD are congruent by calculating their lengths using the distance formula.

[tex]\boxed{\begin{minipage}{7.8 cm}\underline{Distance Formula}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the two endpoints.\end{minipage}}[/tex]

[tex]\begin{aligned}\implies AB & =\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\& =\sqrt{(-4-(-4))^2+(8-1)^2}\\& =\sqrt{(0)^2+(7)^2}\\& =\sqrt{0+49}\\& =\sqrt{49}\\& =7\end{aligned}[/tex]

[tex]\begin{aligned}\implies CD & =\sqrt{(x_D-x_C)^2+(y_D-y_C)^2}\\ & =\sqrt{(5-(-2))^2+(-5-(-5))^2}\\ & =\sqrt{(7)^2+(0)^2}\\ & =\sqrt{49+0}\\ & =\sqrt{49}\\ & =7\end{aligned}[/tex]

Therefore, as AB = CD, this proves that AB and CD are congruent.

The total of yes voter present in the election are 3048.

Now, for the given question;

Let the number of yes voters be 'x'.

Let the number of no voters  be 'y'.

The ratio of yes to no voters is 4:3.

Thus,

x/y = 4/3

or x = 4y/3

Now there are total 5334 voters;

Thus,

x + y = 5334

Put the value of x.

4y/3 + y = 5334

On simplification;

7y = 16002

y = 2286 (no voters)

Now, calculate 'x'.

x = 5334 - 2286

x = 3048 (yes voters)

The centre is at the midpoint of the endpoints of the diameter and r is the distance from the centre to either of the 2 endpoints

Find centre using the ' midpoint formula'

(a , b) = [  (3 - 7),  (4 + 6) ] = (-2 , 5)

to find r use the ' distance formula '

The measure of the angle of the straight line is equal to 180 degrees. the measure of the ∠HLI and ∠ILM is equal to the which is 30 degrees. Thus option 4 is the correct option.

An endlessly long row of evenly spaced dots that spans in both directions makes up a line. Its length is the only dimension it has. A geometry called an angle is created when two line segments, lines, or rays intersect.

Given information-

The measure of the angle KLH is 120 degrees.

The image is attached below for the given problem.

The angle of the straight line

The measure of the angle of the straight line is equal to 180 degrees.

The line KLM is a straight line thus the angle of the line KLM is equal to 180 degrees.

The value of the angle ILH is 30 degrees given in the figure.

The value of the angle KLH is given in the question which is equal to 120 degrees. Thus,

∠KLM = ∠ILM + ∠KLH + ∠ILH

Take the angle KLH and the angle ILH on the other side,

∠ILM = ∠KLM - ∠KLH - ∠ILH

∠ILM = 180 - 120 - 30

∠ILM = 30

Thus the measure of the is 30 degrees.

As the measure of the is equal to the which is 30 degrees. Thus option 4 is the correct option.
