How do I find the inverse of the relation

Answer:

1/2

Step-by-step explanation:

a)  minimum of nine hikers might have covered the distance between 6 and 17 miles because it falls within the standard interval of 10 ≤ x ≤ 15.

b) The maximum no. of hikers who might have covered the distance between 6 and 17 miles is 19.

What do minimum and maximum value mean?

Rearrange the function using fundamental algebraic concepts to get the value of x when the derivative equals 0. This response gives the x-coordinate of the function's vertex, which is where the maximum or minimum will occur. To find the minimum or maximum, rewrite the solution into the original function.

The length AE of the rhombus is √195 units

From the question, we have the following parameters that can be used in our computation:

AD = 4x + 2

DC = 7x - 13

BD = 34

All the four sides of a rhombus are congruent

This means that

DC = AD

Substitute the known values in the above equation, so, we have the following representation

7x - 13 = 4x + 2

Evaluate the like terms

3x = 15

Divide both sides by 3

x = 5

Substitute x = 5 in AD = 4x + 2

So, we have

AD = 4 x 5 + 2

AD = 22

The length AE of the rhombus is then calculated as

AE² = AD² - (BD/2)²

Substitute the known values in the above equation, so, we have the following representation

AE² = 22² - (34/2)²

Evaluate

AE² = 195

Take the square roots

AE = √195

Hence, the length is √195 units

Based on the provided information, Jerry's Z score will be negative, while Corey's Z score will be positive.

A Z-score refers to a numerical measurement that defines the raw value's relationship to the mean of a group of values. It is measured in terms of standard deviations from the mean. If a Z-score is 0, it means that the data point's score is identical to the mean score. A negative z-score indicates that the data point is below average or mean and a positive z-score indicates that the data point is above average or mean. Consider the formula for z score which is given by:

z = (x - µ)/σ where x is the given data value, µ is the mean, and σ is the standard deviation.

Hence, if the x < µ, the z score will be negative while if x > µ, the z score will be positive. As Corey scored higher than the mean on his SAT, his z score will be positive, and Jerry scored lower than the mean on his SAT, his z score will be negative.

We want to study the population formula of a given US state according to exponential equation.

a) 23.1 millions.

b) in 2013 - 2014

What is exponential equation?

The exponential function may be a function denoted by f(x)=\exp or e^. Unless otherwise fixed, the term usually refers to the positive-valued operate of a true variable

Main body:

The population state is:

A = 23.1*e^(0.0153*t)

In millions.

Where t represents the number of years after 2000.

a) For the population at the year 2000, we need to evaluate the function at t = 0 (2000 is 0 years after 2000).

A(0) = 23.1*e^(0.0153*0) = 23.1

The population at year 2000 was 23.1 millions.

b) Now we want to solve:

A(t) = 28.3 = 23.1*e^(0.0153*t)

        28.3/23.1 = e^(0.0153*t)

       1.23 = e^(0.0153*t)

Now we can apply the natural logarithm to both sides:

ln(1.23) = ln( e^(0.0153*t) )

ln(1.23) = 0.0153*t

ln(1.23)/0.0153 = t = 13.5

Hence, 13.5 years after 2000 the population will be 28.3 million.

We have to find the most general antiderivative of the function on the interval (-π/2, π/2).

We know that,

Take the function,

f(x)=7sinx -4secx tanx.

The antiderivative is

= [tex]\int {7sinx-4secxtanx} \, dx[/tex]

= [tex]7\int{sinx} \, dx -4\int {secxtanx} \, dx[/tex]

The equation of the transformed graph will be y = -3(2ˣ) + 2.

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).

Suppose the equation of the given graph is y = A 2ˣ + k.

Substitute,(0,-1)

-1 = A 2⁰ + k

A + k = -1                (1)

Substitute, (1,-4)

-4 = A 2¹ + k

2A + k = -4            

A + k/2 = -2            (2)

Subtract 1 - 2 as

k - k/2 = -1 + 2

k/2 = 1

k = 2

And, A = -2 - 2/2

A = -3

Thus y = -3(2ˣ) + 2

Hence "The equation of the transformed graph will be y = -3(2ˣ) + 2 ".

What is Compound interest?  

Compound interest is interest charged on a loan and is determined by both the principal amount and the rate of interest compounding per year.

The formula for the Amount when compound interest is calculated is given by

                  Amount, A = P(1+r/n)^nt  

P = Principal amount

r = Rate of interest

n = Number of compounds

t = Time period in years

Given:

Principal amount = $ 900

Rate of interest = 6% = 6/100 = 0.06

Number of compounds = 12    [ ∵ compounded monthly]

We need to find the time period

Assume that after 't' years the amount will be doubled

From the given data and formula,

Amount, A = 900(1+0.06/12)^12t        

                  = 900(1+0.06/12)^12t

                  = 900(1 + 0.005)^12t

                  = 900 (1.005)^12t  

As we assumed after 't' years the amount is double

=> 900 (1.005)^12t  = 2 × 900

=>         (1.005)^12t  = 2    

Applying log on both sides

=>  log (1.005)^12t  = log 2

=>    12t log(1.005) = log 2

=>                     12t = log 2/log(1.005)

=>                     12t = 0.30108/ 0.00216  

=>                     12t = 139.888

=>                         t =  11.61

Hence, after  11.61 years the given principal amount of $900 will be double.

Step-by-step explanation:

The solution to the logarithmic expression log²x + log²(x + 10) = log²11 is;

x = -11 and 1

We are given the logarithmic expression as;

log²x + log²(x + 10) = log²11

By the power rule of logarithm, we know that; log²x = 2log x

Thus;

log²x + log²(x + 10) = log²11 can be expressed as;

2log x + 2log (x + 10) = 2log 11

Divide through by 2 to get;

log x + log (x + 10) = log 11

We know from product rule of logarithm that log (ab) = log a + log b. Thus; log x + log (x + 10) = log 11 is;

log x(x + 10) = log 11

Log cancels out to get;

x² + 10x - 11 = 0

4/10 is the fraction that is equivalent to the given fraction model

What is an equivalent fraction ?

According to equivalent fractions, two or more fractions are considered to be equal if, following simplification, both provide the same fraction. Let's imagine that a/b and c/d are two fractions. If these fractions are simplified to produce comparable fractions, such as e/f, they are then equal to one another.

For instance, if we simplify 5/15, the resulting fraction is the same as 1/3, hence that is the equivalent fraction of 1/3.

The fractions with distinct numerators and denominators but the same value are said to be equivalent fractions. For instance, since 2/4 and 3/6 both equal the 12, they are identical fractions. An element of a whole is a fraction. The same amount of the whole is represented by equivalent fractions.

Step-by-step explanation:

to find the zeros set f(x) = 0 , that is

x³ - 3x² - 5x + 15 = 0 ( factor the first/second and third/fourth terms )

x²(x - 3) - 5(x - 3) = 0 ← factor out (x - 3) from each term

(x - 3)(x² - 5) = 0

equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x² - 5 = 0 ( add 5 to both sides )

x² = 5 ( take square root of both sides )

x = ± [tex]\sqrt{5}[/tex]
