What is implicit differentiation?The method of determining the derivative of an implicit function by differentiating each term separately, expressing the derivative of the dependent variable as a symbol, and solving the resulting expression for the symbol.
Here,
Let f(x) = y
Given function,
y = [3x -1]²
The inverse of the above function is given as,
f⁻¹(x) = [∛x + 1]/3
Differentiate the above inverse function,
[f⁻¹(x)]' = 1/[9x²/³]
Substitute x = 1/8
[f⁻¹(1/8)]' = 1/[9(1/8)²/³]
[f⁻¹(1/8)]' = 4 / 9
Thus, the required simplified value of the [f⁻¹(1/8)]' is 4 / 9. Option B is correct.

Assuming exponential decay, determine how many bacteriawill remain after 2 hours from the beginning of the experiment.(Note: First give an exactanswer, then round it to the nearest integer.)
Answer:
208
Step-by-step explanation:
Given that;
Given that;
y= a(1 - b)^t
Where;
wherein y is the final amount, a is the original amount, b is the decay factor, and x is the amount of time that has passed.
To obtain the constant b,
y= ae^-bt
Substituting values;
1000 = 3000 e^-b(50)
1000/3000 = e^b(50)
0.33 = e^b-(50)
ln (0.33) = ln(e^b(-50))
-1.1 = -50b
b= 1.1/50
b= 0.022
After two hours or 120 minutes;
y= 3000(1 - 0.022)^120
y= 207.8661772
y= 208

P(f) = 0.76
P(C) = 0.49
P(fnC) = 0.28
Suppose a shopper is selected from the store at random and learn that they buy clothes. What is the probability that the shopper also buys food?
P(f Given C) = P(f | C)

Suppose we want to test to see if a roulette wheel is balanced. The wheel is spun 100 time resulting in 58 red outcomes. Is this evidence that the roulette wheel is out of balance
Solution :
Here, [tex]$ \hat p$[/tex] = sample proportion of red outcomes
[tex]$ \hat p =\frac{58}{100}$[/tex]
[tex]$ \hat p$[/tex] = 0.58
So we have to test,
[tex]$H_0 : p = 0.5$[/tex]
V/S [tex]$H_a: p \neq 0.5 $[/tex]
The test statistic is
[tex]$z = \frac{\hat p - p}{\sqrt{\frac{p(1-p)}{n}}}$[/tex]
[tex]$z = \frac{0.58 - 0.5}{\sqrt{\frac{0.5(1-0.5)}{100}}}$[/tex]
[tex]$=\frac{0.08}{0.05}$[/tex]
= 1.600
P value using the z table is 0.110
So P value greater than 0.05
Therefore, there is no evidence that roulette wheel is out of balance.

Answer:
the answer is -8
Step-by-step explanation:
Well, first you have to make an equation for what x equals, if that makes sense. So you take the x-y=6 and add y on both sides to get x=(y+6). Then you plug that.

Which value is in the domain of f(x)?
Answer: x = 4
Step-by-step explanation:
Here we have a piecewise function.
One piece works for values of x such that: -6 < x < 0
And the other piece works for values of x such that: 0 < x ≤ 4
Then the domain of this function is:
D = (-6, 0) U (0, 4]
Notice that, becuse we use the symbols ><, the values of x:
x = -6
x = 0
Do not belong to this domain.
While becuase we use the symbol ≤ in the right end, the value x = 4 does belong to the domain.
Then for the given options, the only value that belongs to the domain is the third option, x = 4.
The graph shows the amount of profit in thousands of dollars for a toy each year .A scatter plot of the data is shown below with the line of best fit .
What statement are true related to the line of best fit ? Select all that apply
A.the amount of profit after the first year was around $0.
B.the amount of profit increases about $10,000 each year.
C.the amount of profit decreases about $10,000 each year.
D.the amount of profit after the first year was around $30,000.
E. The amount of profit after 10 years is approximately $120,000.
Answer:
Step-by-step explanation:
We want to confirm which of the given statement is true about the graph.
A) the amount of profit after the first year was around $0
-----------false
From the given graph, the amount of profit after year was far more $0. So the statement above is false.
B) The amount of profit increases about $10,000 each year ------------true
From the line of best fit shown in the graph, the amount of profit increases each year by approximately $10,000.
C) the amount of profit decrease about $10,000 each year ------------ False
From the line of best fit on the graph, we can observe that the amount of profit does not decrease. It rather increases every year.
D) the amount of profit after the first year was around $30,000 ------------true
From the given graph, the amount of profit after the first year is approximately $30,000.
So, the statement is true.
E) the amount of profit after 10 years is approximately $120,000 --------- true
At the year 10 on the graph , the corresponding amount of profit is $120,000.

Answer:
10 Gallons of water will weigh 1.2 pounds.
Step-by-step explanation:
Each gallon weighs 0.12 pounds, I got this answer from dividing 3 by 25 to see how much one gallon weighs. So if we multiply the weight of one gallon by 10, 0.12*10, then we will find out the weight of ten gallons.

10 Gallons of water will weigh 1.2 pounds.
Here, we have,
given that,
Morgan know that 3 gallons of water weigh 25 pounds.
now, we need to find how much do 10 gallons weigh.
so, we get,
3 gallons of water weigh 25 pounds.
so, to see how much one gallon weighs we divide 3 by 25 .
i.e. 3/25 = 0.12
Each gallon weighs 0.12 pounds,
So if we multiply the weight of one gallon by 10,
i.e. 0.12*10, then we will find out the weight of ten gallons.
so, we get,
10 gallons weigh = 0.12*10 = 1.2 pounds.

PLEASE PLEASE PLEASE HELP ME
Answer:
We get the value of x: x= 2
Step-by-step explanation:
Since the triangles are similar, the ratios of the lengths of corresponding sides are same.
We can use proportions to find the value of x
The proportion will be:
[tex]\frac{BD}{DA}=\frac{BE}{EC}[/tex]
Now putting there values we can find value of x
We have:
BD = 6, DA = 4, BE = x+1, EC =x
Putting values
[tex]\frac{BD}{DA}=\frac{BE}{EC}\\\frac{6}{4}=\frac{x+1}{x} \\Cross\:Multiply\\6x=4(x+1)\\6x=4x+4\\6x-4x=4x+4-4x\\2x=4\\x=\frac{4}{2}\\x=2[/tex]
So, we get the value of x: x= 2

what is the measure of E
Answer:
The measure of angle E is:
m∠E = 80°
Step-by-step explanation:
Given
The triangle ΔDEF
It is stated that DE=EF and G is the midpoint of EF.
It means the midpoint G has converted the triangle into two equal right-angles triangles ΔDEG and ΔDFG with the right-angle at G.
Given
m∠GDE = 10°
As the right-angle triangle, ΔDEG lies at the right-angle G.
So, m∠DGE = 90°
as
m∠GDE = 10°
m∠DGE = 90°
m∠E = ?
We know that the sum of angles of a triangle is 180°.
m∠GDE + m∠DGE + m∠E = 180°
10° + 90° + m∠E = 180°
100 + m∠E = 180°
m∠E = 180° - 100
m∠E = 80°
Therefore,
The measure of angle E is: m∠E = 80°
