The sum of two numbers is 39 . the smaller number is 13 less than the larger number. what are the numbers
The required numbers are given as 26 and 13.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
here,
let the number be x and y,
According to the question,
x + y = 39 - - - - (1)
x = y + 13 - - - - - (2)
Put value from equation 2, in equation 1
y + y + 13 = 39
2y = 39 - 13
y = 26/y
y = 13
Now,
x = 13 + 13
x = 26
Thus, the required numbers are given as 26 and 13.

First four terms of f(n)=3n-1
The first four terms of the function f(x) = 3n - 1 are 2, 5, 8, and 11.
Given,
f(n) = 3n - 1
We need to find the first four terms.
What is a function?A function has an input and an output.
Example:
f(x) = x + 1
x = 1,2,3 are inputs.
f(1) = 1 + 4 = 5
f(2) = 2 + 4 = 6
f(3) = 3 + 4 = 7
5, 6, and 7 are the outputs.
We have,
f(n) = 3n - 1
We can assume that the first four terms can be found with n= 1,2,3,4.
f(1) = 3 x 1 - 1 = 3 - 1 = 2
f(2) = 3 x 2 - 1 = 6 - 1 = 5
f(3) = 3 x 3 - 1 = 9 - 1 = 8
f(4) = 3 x 4 - 1 = 12 - 1 = 11
Thus the first four terms of the function f(x) = 3n - 1 are 2, 5, 8, and 11.

The function f(x) = ax^3 -x^2 + bx -24 has three factors. Two of these factors are x-2 and x+4. Determine the values of a and b, then determine the other factor. (My Nelson Advanced Functions Grade 12 book chapter 3)

The roots of any equation, always satisfies that equation.
Values of , a = - 2 and b = 22
Other factor of given function is (x - 3/2)
The given function [tex]f(x) = ax^3 -x^2 + bx -24[/tex]
Since, (x - 2) and (x + 4) are factors of given function
Therefore, x = 2 and x = -4 satisfies the given function.
[tex]f(2)=8a-4+2b-24=0\\8a+2b=28\\\\f(-4)=-64a-16-4b-24=0\\-64a-4b=40\\-16a-b=10[/tex]
Now , solving above two equation by elimination method
We get, a = -2 and b = 22
So, [tex]f(x) = -2x^3 -x^2 + 22x -24[/tex]
To find other factors , we divide above function by multiplication of (x - 2)(x+4).
So we get other factors, (x - 3/2)

You are playing a video game. For each diamond you collect, you earn 80 points. You also earn 100 bonus points by completing the level in less than 2 minutes. You need to earn more than 1220 points to continue on to the next level. Write and solve an inequality that represents the numbers dd of diamonds you must collect in less than 2 minutes to advance to the next level.
Given
For each diamond you collect, you earn 80 point
earn 100 bonus points by completing the level in less than 2 minutes.
earn more than 1220 points to continue on to the next level
Find the inequality that represents the numbers dd of diamonds you must collect in less than 2 minutes to advance to the next level.
To proof
As given in the question
For each diamond earn point = 80
bonus points by completing the level in less than 2 minutes = 100
earn more than 1220 points to continue on to the next level
Let us assume that the number of diamond = d
The inequality written in the form
we get
[tex]80d + 100 \geq 1220[/tex]
now solving the above equation
[tex]80d \geq1120[/tex]
[tex]d \geq14[/tex]
Thus the numbers of diamonds you must collect in less than 2 minutes to advance to the next level be 14.
Hence proved

Given :
A six sided die is tossed two times and '3' shows up both times
'3' shows up both the times .
When the dice is rolled third time. there are 6 possibilities comes up
In the third trial , we have six possibilities 1,2,3,4,5,6
Out of six possibilities , the chance of getting '3' is only once
So, the probability of a '3' on the third trial is [tex]\frac{1}{6}[/tex]
