x^2 = x3
x^2 - 3x = 0
x(x - 3) = 0
x = 0 and x -3 = 0 or x = 3
x cannot equal zero, therefore the answer is three
The numbers that when squared equal to three times themselves are 0 and 3. This is found by solving the quadratic equation x² = 3x, which factors to x(x - 3) = 0.
To express this mathematically, we let 'x' represent the number, so the equation becomes x² = 3x. This is a quadratic equation that can be solved by rearranging the terms and factoring, resulting in x(x - 3) = 0. Applying the Zero Product Property, we have two potential solutions for x: 0 or 3. Therefore, the numbers that fit the condition are 0 and 3.
Compare the three functions below. Which has a greater period? A) y = 3cos(2x+1), B) y=5cos(4x +8), and C) y=cos(2x+4) (4.3)
Comparing the periods of the given cosine functions indicates that functions A) and C) both have the greatest period of π, which is longer than the period of function B), π/2.
Explanation:To compare the periods of the given functions, let's first understand what the general form of a cosine function tells us about its period.
The general form is y = A cos(Bx + C), where A is the amplitude, B affects the period, and C is the phase shift.
The period of such a function is given by 2π / |B|.
For function A) y = 3cos(2x+1), B = 2, thus its period is π.
For function B) y=5cos(4x +8), B = 4, yielding a period of π/2.
Lastly, for function C) y=cos(2x+4) (4.3), assuming the (4.3) is an unrelated notation and focusing on the given cos component with B = 2, its period is also π.
The function with the greatest period among A, B, and C is thus A) and C), both having the same period of π, which is greater than the period of B).

Simplify (x5/8)2/3 look at the picture
Answer:
[tex]x^{\frac{5}{12} }[/tex]
Step-by-step explanation:
In the question given we use the law of exponents;
[tex](a^{b})^{c} = a^{bc}[/tex]
If a base a is raised to a power b and the entire expression raised to a power c, the resulting expression is simply equal to the base a raised to the product of the two exponents b and c, that is bc.
In the case given,
a = x
b = 5/8
c = 2/3
To simplify the expression we simply multiply b and c;
bc = 5/8 * 2/3
= 5/12
The simplified expression is thus;
[tex]x^{\frac{5}{12} }[/tex]
Answer:
The correct answer is ((x⁵/⁸)²/³) = x⁵/¹²
Step-by-step explanation:
Points to remember:-
Identity
(xᵃ)ᵇ = xᵃᵇ
Here it is given that, ((x⁵/⁸)²/³)
To find the value of ((x⁵/⁸)²/³)
(5/8) * (2/3) = (5 * 2) /(8 * 3) = 10/24 = 5/12
By using identity (xᵃ)ᵇ = xᵃᵇ we can write,
((x⁵/⁸)²/³) = x⁽⁵/⁸⁾ˣ⁽²/³⁾
= x⁵/¹²
Therefore the correct answer is ((x⁵/⁸)²/³) = x⁵/¹²

Identify the excluded values of the rational expression x^2+2x-3/x^2+5x+6
Answer:
x cannot equal -3, and x cannot equal -2
Step-by-step explanation:
Answer:
The excluded values of the rational expression are -3 and -2.
Step-by-step explanation:
If a ration function is defined as [tex]R(x)=\frac{p(x)}{q(x)}[/tex], then the excluded values of the rational function are those values for which q(x)=0.
The given rational expression is
[tex]\frac{x^2+2x-3}{x^2+5x+6}[/tex]
Factories the numerator and denominator.
[tex]\frac{x^2+3x-x-3}{x^2+3x+2x+6}[/tex]
[tex]\frac{x(x+3)-1(x+3)}{x(x+3)+2(x+3)}[/tex]
[tex]\frac{(x+3)(x-1)}{(x+3)(x+2)}[/tex] .... (1)
Equate the denominator equal to 0.
[tex](x+3)(x+2)=0[/tex]
Using zero product property,
[tex]x+3=0\Rightarrow x=-3[/tex]
[tex]x+2=0\Rightarrow x=-2[/tex]
Therefore the excluded values of the rational expression are -3 and -2.
Cancel out the common factors of equation (1)
[tex]\frac{x - 1}{x + 2}[/tex] for (x≠-3)
It means x=-2 is vertical asymptote and x=-3 is hole.
PLEASE HELLLLLLLPPPPPP!!!!!
Answer:
A.
Step-by-step explanation:
First, let's define the types of numbers.
Real numbers: a value that represents a quantity along a continuous line
ex: 1, 5, -6, 0.125, 45.5258,
Integer: Zero, any positive or negative number
ex: -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5....
Whole numbers: a number without fractions [not negative]
ex: 0, 1, 2, 3, 4, 5.....
Rational numbers: any number that can be expressed as the quotient or fraction
ex: 1, 2, 3, 4, 5
Irrational numbers: any number that can't be expressed at the quotient or fraction
ex: pi, [3.14.... (never ending decimal)] square root of 2....
Based on this information, the false statment would be A. I believe, because
pi is a real number and it is an irrational number.

Priya has completed 9 exam questions. This is 60% of the questions on the exam. How many questions are on the exam?
Answer:
15
Step-by-step explanation:
Since 9 questions is 60% of the exam, you must find 100%. You could find the value of 10% by dividing 60 by 6. You do the same to 9, divide by 6 to get 1.5. Now that you have the value of 10% you can multiply 10% by 10 to get 100. You also do the same to 1.5. Your answer should be 15, if not check your work again. Work hard!!
The total number of questions in the exam is 15 and this can be determined by using the unitary method.
Given :

Answer: Option B
[tex]f(g(x)) = 4x^2 -41x + 105[/tex]
Step-by-step explanation:
We have 2 functions
[tex]f(x) = 4x -\sqrt{x}[/tex]
[tex]g(x) = (x-5)^2[/tex]
We must find [tex]f(g(x))[/tex]
To find this composite function enter the function g(x) within the function f(x) as follows
[tex]f(g(x)) = 4(g(x)) -\sqrt{(g(x))}[/tex]
[tex]f(g(x)) = 4(x-5)^2 -\sqrt{(x-5)^2}[/tex]
By definition [tex]\sqrt{a^2} = |a|[/tex]
So
[tex]f(g(x)) = 4(x-5)^2 -|x-5|[/tex]
Since x is greater than 5 then the expression [tex](x-5)> 0[/tex].
Therefore we can eliminate the absolute value bars
[tex]f(g(x)) = 4(x-5)^2 -(x-5)[/tex]
[tex]f(g(x)) = 4(x^2 -10x + 25) -(x-5)[/tex]
[tex]f(g(x)) = 4x^2 -40x + 100 -x+5[/tex]
[tex]f(g(x)) = 4x^2 -41x + 105[/tex]

The cargo area of a truck is 8 1\2 feet long, 6 feet wide, and 10 1\2 feet high. The volume of the cargo area is cubic feet.
The formula for finding the volume of a rectangular prism (the cargo area of the truck is the shape of a rectangle in 3D; a rectangular prism) is V = (l)(w)(h); where l = length, w = width, and h = height.
First, substitute the known values into the equation:
l = 8.5
w = 6
h = 10.5
V = (8.5)(6)(10.5)
(Note: .5 = 1/2)
Now, all we need to do is simplify:
V = 535.5 ft³ OR 535 1/2 ft³
(Note: ft³ is the condensed form of cubic feet)
You can pick whichever form your test directs you to use. They are both the same value though.
Hope this helps!
The volume of the cargo area of the truck is 519.75 cubic feet.
The volume of the cargo area of the truck can be calculated by multiplying its length, width, and height. Given the dimensions in feet are:
Length = 8 1/2 feet = 8.5 feet = 8 + 1/2 feet
Width = 6 feet
Height = 10 1/2 feet = 10.5 feet = 10 + 1/2 feet
To find the volume, we convert the mixed numbers to improper fractions and then multiply:
Length in fractions = 8 + 1/2 = 17/2 feet
Width in fractions = 6 = 6 * 2/2 = 12/2 feet
Height in fractions = 10 + 1/2 = 21/2 feet
Now, multiply the dimensions to find the volume:
Volume = Length * Width * Height
Volume = (17/2 feet) * (12/2 feet) * (21/2 feet)
Volume = (17 * 12 * 21) / (2 * 2 * 2) cubic feet
Volume = 4158 / 8 cubic feet
Simplifying the fraction, we get:
Volume = 519.75 cubic feet

Which function is equivalent to f(x) = lnx?
f(x) = log3x
f(x) = log10x
f(x) = logbx
f(x) = logex
Answer:
[tex]f(x)=log_ex[/tex]
Step-by-step explanation:
By definition, we can write ln instead of log. WHEN??
Whenever the base of the logarithm is the number "e".
Hence, when we have:
[tex]Log_e[/tex]
We can write it in shortcut as:
[tex]Log_e=ln[/tex]
Hence, ln x can also be written as [tex]Log_ex[/tex]
Fourth answer choice is right.
Answer:
[tex]f(x) = log_e(x)[/tex]
Step-by-step explanation:
[tex]f(x) = ln x[/tex]
For logarithmic function ln(x) the base of ln is 'e'
[tex]f(x) = log_3(x)[/tex]
The base of log is 3 . so it is not equivalent to [tex]f(x) = lnx[/tex]
[tex]f(x) = log_{10}(x)[/tex]
The base of log is 10 . so it is not equivalent to [tex]f(x) = lnx[/tex]
[tex]f(x) = log_b(x)[/tex]
The base of log is b . so it is not equivalent to [tex]f(x) = lnx[/tex]
[tex]f(x) = log_e(x)[/tex]
The base of log is e . so it is equivalent to [tex]f(x) = lnx[/tex]

A right triangle △ABC with right angle C is inscribed in a circle. Find the radius of this circle if: Given m∠C = 90°, k(O, r) inscribed in △ABC, AC = 8 cm, BC = 6 cm. Find r.
Answer:
The radius is [tex]r=5\ cm[/tex]
Step-by-step explanation:
we know that
The inscribed angle is half that of the arc it comprises.
so
[tex]m<C =(1/2)[arc\ AB][/tex]
[tex]m<C =90\°[/tex]
substitute
[tex]90\°=(1/2)[arc\ AB][/tex]

That means----> The length side AB of the inscribed triangle is a diameter of the circle
Applying Pythagoras Theorem
Calculate the length side AB
[tex]AB^{2}=AC^{2}+BC^{2}[/tex]
[tex]AB^{2}=8^{2}+6^{2}[/tex]
[tex]AB^{2}=100[/tex]
[tex]AB=10\ cm[/tex] -----> is the diameter
Find the radius
[tex]r=10/2=5\ cm[/tex] -----> the radius is half the diameter
