What is f(x)=3 x¹/₃ for x=1/125 ?
(F) 15 (G) 3/5 (H) ∛3/5 (I) 5∛3
The value of the given expression for x=1/1250is 3/5. The correct option is (G).
Given the expression is f(x)=[tex]3x^{\frac{1}{3}}[/tex].
The cube root of a number is the factor that we want multiply by itself three times to get that number. The symbol for the cube origin is 3 cube roots, the last cube root. Finding the cube root of any number is the opposite of cubing a number.
We will simplify the given expression by using substitution method and cube root.
Firstly, we will substitute x=1/125 in the given expression f(x)=[tex]3x^{\frac{1}{3}}[/tex], we get
f(x)=[tex]3\left(\frac{1}{125}\right)^{\frac{1}{3}}[/tex]
As we know that the cube root of √125 is 5.
Now, we want to simplify the above equation, we get
f(x)=3(1/5)
f(x)=3/5
Hence, the value of [tex]f(x)=3x^{\frac{1}{3}}[/tex] for x=1/125 is 3/5.

What is an equation of the line that passes through the points (7,-3) and
(-8,-3)?
Answer:
Step-by-step explanation:
m= [ -3-(-3)] ÷ [-8-7} = 0
Therefore, the slope of the line is 0.
Now use the slope and either of the two points to find the y-intercept.
y= mx+b
-3= (0)(7)+b
b=-3
Write the equation in slope intercept form as:
y= mx+b
y= (0)x-3
y= -3
Hence, the equation of the line is y= -3.

if f (2) =-5, what does 5 represent
We can state that, 5 represents the output of the function at x = 2.
How to Interpret Functions?A function is a relation whereby each input gives only one possible output for the function.
For example, "f(x)" is the output of a typical function that is given by an input of "x".
Given the function statement, f(2) = -5, the input is x = 2, the output is -5. This means that, the function that has an input of 2, will give an output of -5.
-5, therefore, represents the output of the function when the input, x = 2, that is, f(-2) = -5.
Thus, we can state that, 5 represents the output of the function at x = 2.

(A) 45% of 120
Multiply 45/100 with 120 =(45/100) x 120 = (45 x120) / 100 = 54.
(B) 81 is 75%
Formula = Number x 100/Percent
= 81 x 100/ 75 = 108
Following shows the steps on how to derive this formula and find out 75% of what number is 81. Then take 100% of that figure. Setup the equation
81/75% = Y/100%
Solve for Y
Using cross multiplication of two fractions, we get

In a sale, normal prices are reduced by 25%. Freddie bought a car in the sale. The sale price of the car was £7500. Work out the normal price of the car.
The normal price of the car on the basis that the sale price of the car was £7500 is £10,000.
What percentage of the normal price is the sales price?The fact that the normal prices are reduced by 25% means that the actual price paid eventually is 75%, which is 100% minus discount of 25%, hence, the actual price of £7500 paid eventually represents 75% of normal price

Jake is a factory manager for a company that produces batteries. Occasionally, some are found to be defective. Based on previous results, Jake estimates that 12 batteries will be defective for a certain month. However, 10 were actually defective. What is the percent error of Jake’s estimate?
Based on the estimated number of defective batteries and the number of batteries that were actually defective, the percent error of Jake's estimate is 20%
How to find the percent error?The percent error of a problem can be found by the formula:
= (Expected results - Actual results) / 100%
Expected results = 12 defective batteries
Actual results = 10 defective batteries
Jake's percentage error is therefore:
= (12 - 10) / 100%
= 2 / 10 x 100%
= 0.2 x 100%
= 20%

Write an equation for each situation, in terms of t , t, and determine the number hours, t , t, that would make the cost of each company the same.
Answer:
At 10 hours both companies charge the same rate. So Company A is cheaper if the time is less than 10 hours and after 10 hours, company B is cheaper.
Step-by-step explanation:
It is given that Chloe is deciding between two landscaping companies for her place of business. Company A charges $70 per hour and a $150 equipment fee. Company B charges $55 per hour and a $300 equipment fee. Let A A represent the amount Company A would charge for t t hours of landscaping, and let B B represent the amount Company B would charge for t t hours of landscaping.
Now, we need to write an equation for each situation, in terms of t , t, and determine the number hours, t , t, that would make the cost of each company the same.
Now,
Let A(t) = 70t + 150
Let B(t) = 55t + 300
Further, on equating both the equations at same rate to determine the time t;
=> 70t + 150 = 55t + 300
=> 15t = 150
=> t = 10
Therefore, at 10 hours both companies charge the same rate. So Company A is cheaper if the time is less than 10 hours and after 10 hours, company B is cheaper.

Good Evening. Please I really need help for this Further Math Question. Thanks
You should be aware of the fundamental theorem of algebra (FTCoA). If a quadratic has roots at [tex]r_1[/tex] and [tex]r_2[/tex], then we can factorize it as
[tex](x - r_1) (x - r_2)[/tex]
Expanding, this is equivalent to
[tex]x^2 - (r_1 + r_2) x + r_1 r_2[/tex]
Now, if we can also write this
[tex]x^2 + bx + c[/tex]
then we must have
[tex]x^2 + bx + c = x^2 - (r_1 + r_2) x + r_1r_2 \\\\ ~~~~ \implies \begin{cases} b = -(r_1 + r_2) \\ c = r_1r_2 \end{cases}[/tex]
(By the way, these are known as Vieta's formulas.)
We're told that the quadratic,
[tex]p(x) = 3x^2 - 6x + 8,[/tex]
has roots [tex]x=\alpha[/tex] and [tex]x=\beta[/tex], so by the FTCoA, we can write
[tex]p(x) = 3 (x - \alpha) (x - \beta)[/tex]
Expanding this last form, we have the identity and exact values
[tex]3x^2 - 6x + 8 = 3 (x^2 - (\alpha + \beta) x + \alpha\beta) \\\\ ~~~~ \implies x^2 - 2x + \dfrac83 = x^2 - (\alpha + \beta) x + \alpha\beta \\\\ ~~~~ \implies \begin{cases} \boxed{\alpha + \beta = 2} \\\\ \boxed{\alpha\beta = \frac83} \end{cases}[/tex]
(i) We want to construct a new quadratic [tex]p_{\rm i}(x)[/tex] such that its roots are [tex]x=\alpha^2[/tex] and [tex]x=\beta^2[/tex]. By the FTCoA, we would have
[tex]p_{\rm i}(x) = (x - \alpha^2) (x - \beta^2)[/tex]
Expanding,
[tex]p_{\rm i}(x) = x^2 - (\alpha^2 + \beta^2) x + \alpha^2\beta^2[/tex]
Now, notice that
[tex]\alpha^2 + \beta^2 = (\alpha + \beta)^2 - 2\alpha\beta = 2^2 - 2\cdot\dfrac83 = -\dfrac43[/tex]
[tex]\alpha^2\beta^2 = (\alpha\beta)^2 = \left(\dfrac83\right)^2 = \dfrac{64}9[/tex]
It follows that
[tex]p_{\rm i}(x) = x^2 + \dfrac43 x + \dfrac{64}9[/tex]
which we can rewrite with integer coefficients by scaling each term by a factor of 9 to get
[tex]p_{\rm i}(x) = \boxed{9x^2 + 12x + 64}[/tex]
(ii) Now we want a quadratic [tex]p_{\rm ii}(x)[/tex] with roots at [tex]2\alpha[/tex] and [tex]2\beta[/tex]. This means
[tex]p_{\rm ii}(x) = (x - 2\alpha) (x - 2\beta) \\\\ ~~~~~~~~ = x^2 - 2 (\alpha + \beta)x + 4\alpha\beta[/tex]
[tex]\implies p_{\rm ii}(x) = x^2 - 4x + \dfrac{32}3[/tex]
or more cleanly, scaling by 3,
[tex]p_{\rm ii}(x) = \boxed{3x^2 - 12x + 32}[/tex]
(iii) Now the roots are [tex]x=\frac\alpha2[/tex] and [tex]x=\frac\beta2[/tex], which gives
[tex]p_{\rm iii}(x) = \left(x - \dfrac\alpha2\right) \left(x - \dfrac\beta2\right) \\\\ ~~~~~~~~ = x^2 - \dfrac{\alpha + \beta}2 x + \dfrac{\alpha\beta}4[/tex]
[tex]\implies p_{\rm iii}(x) = x^2 - x + \dfrac8{12}[/tex]
[tex]\implies p_{\rm iii}(x) = \boxed{12x^2 - 12x + 8}[/tex]
(iv) If the roots are [tex]x=\frac\alpha{\alpha+1}[/tex] and [tex]x=\frac\beta{\beta+1}[/tex], we have
[tex]p_{\rm iv}(x) = \left(x - \dfrac\alpha{\alpha+1}\right) \left(x - \dfrac\beta{\beta+1}\right) \\\\ ~~~~~~~~~= x^2 - \left(\dfrac\alpha{\alpha+1} + \dfrac\beta{\beta+1}\right) x + \dfrac{\alpha\beta}{(\alpha+1)(\beta+1)}[/tex]
Note that
[tex]\dfrac\alpha{\alpha+1} + \dfrac\beta{\beta+1} = \dfrac{\alpha(\beta+1) + \beta(\alpha+1)}{(\alpha+1)(\beta+1)} \\\\ ~~~~~~~~~~~~~~~~~~~~ = \dfrac{2\alpha\beta + \alpha + \beta}{\alpha\beta + \alpha + \beta + 1} \\\\ ~~~~~~~~~~~~~~~~~~~~ = \dfrac{\frac{16}3 + 2}{\frac83 + 2 + 1} \\\\ ~~~~~~~~~~~~~~~~~~~~ = \dfrac{22}{17}[/tex]
[tex]\dfrac{\alpha\beta}{(\alpha+1)(\beta+1)} = \dfrac{\alpha\beta}{\alpha\beta + \alpha + \beta + 1} \\\\ ~~~~~~~~~~~~~~~~~~~~~ = \dfrac{\frac83}{\frac83 + 2 + 1} \\\\ ~~~~~~~~~~~~~~~~~~~~~ = \dfrac8{17}[/tex]
[tex]\implies p_{\rm iv}(x) = x^2 - \dfrac{22}{17}x + \dfrac8{17}[/tex]
[tex]\implies p_{\rm iv}(x) = \boxed{17x^2 - 22x + 8}[/tex]

What exactly is a function's inverse?Inverse functions are those that cancel one another out. In other words, if g(x) is f's inverse, then f(g(x)) = g(f(x)) = x. (x). Given an equation for which we want the inverse, we have a fantastic method we can utilize to do this.
Not every function has a counterpart. If f(x) has an inverse, it is clear to see that it will never again have the same value. We give this resource a special name.
Inverse variation is y = k. 1/x
given y = 7
x = 3
So, 7 = k. 1/3
So, the value of k = 21
We can conclude that the value of constant variation is 21
