Solve by factoring. Check your answers. 2 x²+x=3
The factoring of the expression 2 x²+x=3 is (x-1) (2x+3)
By ordering the values, we get:
2x² + x - 3 = 0
To solve this exercise, we have to follow the rules of factoring:
1. Factor 1 from 1x:
2x² + x - 3 = 0
2x² + (-2 + 3) x -3 = 0
2. Apply the distributive property:
2x² - 2x + 3x - 3 = 0
3. Groups the first two terms and the last two terms:
(2x² - 2x) + 3x - 3 = 0
4. Factorize the greatest common denominator (GCM) of each group:
2x(x - 1) + 3(x - 1) = 0
5. Simplify the common term (x - 1) with the distributive property:
(x-1) (2x+3)

Simplify each expression.
ln e²
ln(e²) = 2, by properties of logarithm.
What is Logarithm?The opposite of exponentiation is the logarithm.This indicates that the exponent to which a fixed number, base b, must be raised in order to obtain a specific number x, is represented by the logarithm of that number.A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.
Now, as we know by properties of logarithm, [tex]log_b(a)^m = m(log_b(a))[/tex],
ln (e²) = 2 ( ln(e))
Also, as ln (e) = 1, ln (e²) = 2 (1) = 2.
Hence, ln(e²) = 2, by properties of logarithm.

Landscaping A homeowner is planting hedges and begins to dig a 3 -ft-deep trench around the perimeter of his property. After the first weekend, the homeowner recruits a friend to help. After every succeeding weekend, each digger recruits another friend. One person can dig 405 ft³ of dirt per weekend. The figure at the right shows the dimensions of the property and the width of the trench.
a. Geometry Determine the volume of dirt that must be removed for the trench.
The trench will require 9168 cubic feet of dirt to be removed.
Here, we are given that a homeowner is digging a 3 -ft-deep trench around the perimeter of his property.
Length of the property = 210 feet
Breadth of the property = 180 feet
Let us now consider one side of the 180-foot-long trench.
There are two such trenches, each with a width of 4 feet and a height of 3 feet.
Thus the volume of the trench = 2(length × breadth × height)
Volume = 180 × 4 × 3 × 2
= 4320 cubic feet
Now we are left with two other sides of the trench with the following dimensions-
Height = 3ft
Breadth = 4ft
Length = 210 - 8 = 202ft
Thus, volume = 202 × 4 × 3 × 2
= 4848 cubic feet
Thus, the total volume of the trench = 4848 + 4320 = 9168 cubic feet.
Hence, The removal of 9168 cubic feet of earth is necessary.

If the digits can be repeated, how many possible codes are there?
There are_______ different codes. ( Need this one answered)
There are 10000 different possible codes to guess the correct code on the first try..
A percentage, or a figure between 0 and 100 percent, can also be used to express probability. The likelihood of an event occurring increases with its probability value or percentage. How many potential outcomes an event has will determine how likely it is to occur.
1)There are 5040 possible codes if the digits are not repeated.
2)Probability of guessing correct code on first try p = 1/5040.
3)There are 10000 different codes, if the digits are repeated.
Given,
Total digits = 10.
{0,1,2,3,4,5,6,7,8,9}
4 digit code must be formed.
1. Code without repeating digits
→ 4 digit code
Therefore possible ways = 10×9×8×7
= 5040
2. Probability of guessing correct code on first try.
n(A)→ event which has correct code=1
n(S)→total possible ways=5040.
P(A) = n(A)/n(S) = 1/5040

tyrone likes to snack on his big bag of candy. he takes 888 pieces of candy from the bag each time he snacks. after he has snacked 181818 times, there are only 666 pieces of candy remaining in the bag. the number ccc of pieces of candy remaining in the bag is a function of sss, the number of snacks tyrone eats.
The function's formula is given by c=150-8s .
It is given in the question that
number of candies taken by tyrone in each snack = 8
number of times tyrone snacks = 18
Total candies= (number of times tyrone snacks)x(number of candies taken in each snack )
Total candies=18x8=144.
There are 6 candies left in the bag .
So total candies = 144+6=150.
It is also given that "s" is the number of snacks tyrone eats .
and "c" is the number of candies remaining.
number of candies tyrone eats in each snack = 8
number of candies tyrone eats in s each snack =8s
the number of candies remaining = (total candies) - (number of candies tyrone eats in s each snack ).

The gradient of the line is change in y/ change in x
Thus meaning the gradient is 1. (defined as x)
The line crosses through the y-axis on the point (0,6)
So your euqation will be y = (1 - the gradient) x + (interception of y-axis) 6
Answer:
y = x + 6
Step-by-step explanation:
The general form of an equation of a line is
y= mx+b
y = slope ·x + y-intercept
Find the slope of the line, m:
-Pick any 2 points on the line, for example lets pick the points (0, 6) and (3, 10)
-Start at any of the points and go towards the other while note the path
start at (0, 6) and to go to (4, 10) we have to
go up (rise) 4 units from 6 to 10 and
go to the right (run) 4 from 0 to 4.
Slope = m = rise/run = 4/4 = 1
m = 1

For each annual rate of change, find the corresponding growth or decay factor. -0.1%
The decay factor for the annual rate of change of -0.1 % is 0.999.
A quantity must vary by a specific percentage each time period in order for growth or decay to be exponential.
With the function displayed to the right, you may represent exponential growth or decay.
A(x) = a( 1 + r)ˣ
Where A is the amount after x time periods, a is the initial amount, x is the number of time periods, and r is the rate of change.
Now, we have the annual rate of change as:
r = - 0.1 % = - 0.1 / 100 = - 0.001
From the function A(x) = a( 1 + r)ˣ , the corresponding factor is 1 + r.
So, let B = 1 + r
B = 1 + r
B = 1 + (- 0.001)
B = 1 - 0.001
B = 0.999
Now, the value of B is less than 1 therefore, the corresponding decay factor is 0.999.

Does every function have an inverse which is a function? Does every relation have an inverse which is a relation?
No, all functions do not have an inverse functions. Those that do exists named invertible.
What is meant by inverse function?The inverse function of a function f in mathematics exists a function that reverses the operation of f. If the inverse of f exists, it is shown by the f⁻¹. The inverse of f exists if and only if f is bijective.
An inverse in mathematics is a function that "undoes" another function. In other words, if f(x) produces y, then y entered into the inverse of f produces x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f ⁻¹.
In mathematics, an inverse function (or anti-function) exists as a function that "reverses" another function: if the function f used to an input x gives a result of y, then using its inverse function g to y gives the result x, i.e., g(y) = x if and only if f(x) = y.For a function f: X → Y to have an inverse, it must have the property that for every y in Y, there is exactly one x in X such that f(x) = y. This property ensures that a function g: Y → X exists with the necessary relationship with f.No, all functions do not have an inverse functions. Those that do are called invertible.

A university's freshman class has 8600 students. 1634 of those students are majoring in Economics. What percentage of the freshman class are Economics majors?
Answer:

PercentagesPercentages are evaluated values that say how much of a whole is occupied by that value. For example, if we were to say 75% of a strawberry pie remained, we could also see this as 3/4, or three-fourths.
To solve this particular problem, we will need to divide two values and convert a decimal to a percentage.
SolveFirst, set up the fraction of economics majors that are freshman students to the total number of freshman students.
[tex]\displaystyle \frac{1634}{8600}[/tex]
Then, divide the two using a calculator or long division.
[tex]\displaystyle \frac{19}{100}[/tex]
Finally, to convert this to a decimal, use a calculator.
[tex]0.19[/tex]
To convert a decimal to a percentage, multiply the decimal by 100.
[tex]0.19 \times 100 = 19\%[/tex]
The final answer is [tex]19\%[/tex].

[tex]\frac{1634}{8600}[/tex]
Our next step is to grab a calculator and input 1634 ÷ 8600. You can alternatively use the long division method but a calculator would work best. After calculating, your answer should come out to be 0.19
Now, you need to multiply it by 100 so that you can create a percentage.
0.19 × 100 = 19%
