Answer:

The function can have its own inverse, that is, [tex]$f^{-1}(x)=f(x)$[/tex] and this type of function is called an involution. Example f(x)=6-x.

Step-by-step explanation:

A statement that a function can be its own inverse is given.

It is required to explain whether a function has its own inverse. Then explain whether the given statement satisfies the condition.

Step 1 of 3

Consider a function is f(x)=6-x.

This function is a continuous function for all values of x. This function is also a linear function. So, every continuous linear function is a one-to-one function.

So, this function is one-to-one.

Step 2 of 3

Consider f(x) as y and rewrite the equation.

The equation becomes [tex]$y=6-x$[/tex]

Solve the rewritten equation.

Add -6 on both sides of the equation.

[tex]$$\begin{aligned}&y=6-x \\&y-6=6-x-6 \\&y-6=-x\end{aligned}$$[/tex]

Step 3 of 3

Multiply by -1 on both sides.

[tex]$$\begin{aligned}&y-6=-x \\&(-1)(y-6)=(-x)(-1) \\&-y+6=x \\&x=6-y\end{aligned}$$[/tex]

Interchange x and y in solved equation.

[tex]$$\begin{aligned}&x=6-y \\&y=6-x\end{aligned}$$[/tex]

So, the inverse of the given function is [tex]$f^{-1}(x)=6-x$[/tex].

The function and inverse of the function are the same, that is, [tex]$f^{-1}(x)=f(x)$[/tex]

So, a function can have its own inverse. This type of function is called an involution.

The volume of rectangular prism = lwh

where

Therefore,

height of fluffy cage can be calculate as follows:

4340 = 20 × 14 × h

4340 = 280h

h = 4340 / 280

h = 15.5 inches

height of Kenneth cage can be calculate as follows:

5250 = 20 × 15 × h

5250 = 300h

h = 5250 / 300

The cost of electricity consumed by the TV per month is $4.968.

In the question, we are given that a TV set consumes 120W of electric power when switched on. It is kept on for a daily average of 6 hours per day. The number of days in the month is given to be 30 days. The cost per unit of electricity is 23 cents per kWh.

We are asked to find the cost of electricity the TV consumes in the month.

The daily energy consumed by the TV = Power*Daily time = 120*6 Wh = 720 Wh.

The monthly energy consumed by the TV = Daily energy*Number of days in the month = 720*30 Wh = 21600 Wh = 21600/1000 kWh = 21.6 kWh.

Hence, the total cost of electricity the TV consumes = Monthly energy*Per unit cost = 21.6*23 cents = 496.8 cents = $496.8/100 = $4.968.

Therefore, the cost of electricity consumed by the TV per month is $4.968.

The equation connecting L, m, A is L = [tex]\frac{1.8m}{A}[/tex]

Variation is a mathematical relationship that shows how a certain variable behaves when other variables depending on it increase or decrease.

The types of variation are: Direct, indirect, joint and partial.

Analysis:

L ∝ [tex]\frac{m}{A}[/tex]

introducing a constant K to replace the proportionality sign,

L = [tex]\frac{Km}{A}[/tex]

when L = 18, m = 0.4, A = 0.4

Answer:

(a) 1416

(b) 2 × 2 × 2 × 3 × 59

Step-by-step explanation:

The prime numbers between 0 and 10 are 2, 3, 5,7 (1 is not considered prime)
Therefore m = 2357

The square numbers between 0 and 10 are  1, 4, 9 and in descending order 9,4.1so n = 941

m - n = 2357 - 941 = 1416

Unique prime factors of 1416 are 2,3,59

1416 as a product of prime factors = 2 × 2 × 2 × 3 × 59

Answer:

The cost of 30 gallons of gas is $74.7.

Step-by-step explanation:

Step 1 of 3

Here we need to find the cost of 30  gallons.

Given that the price that Tyler pays for gas varies directly with the number of gallons he buys.

The cost of 24  gallons is $59.76  to him.

Let, x  be the number of gallons and y  be the cost or price for gas.

Use the formula for direct variation which is given by y=kx.

Step 2 of 3

Now substitute the value y=$59.76 and x=24.

Put value in y=kx, we get

[tex]$$\begin{aligned}&59.76=k \times 24 \\&k=2.49\end{aligned}$$[/tex]

Substitute value of k is y=kx, we get y=2.49x

Step 3 of 3

Now we need to find the value of y that is the cost for 30 gallons.

Again use direct variation formula y=kx and value of k and x, we get [tex]$y=2.49 \times 30$[/tex]

[tex]$$y=74.7$$[/tex]

Step-by-step explanation:

[tex]\sqrt{-64}[/tex] and [tex]\sqrt{-16}[/tex] can be expressed in complex form, with [tex]\sqrt{-1}[/tex] = i

[tex]\sqrt{-64}[/tex] = [tex]\sqrt{64(-1)}[/tex] = [tex]\sqrt{64}[/tex] × [tex]\sqrt{-1}[/tex] = 8i

[tex]\sqrt{-16}[/tex] = [tex]\sqrt{16(-1)}[/tex] = [tex]\sqrt{16}[/tex] × [tex]\sqrt{-1}[/tex] = 4i

the factors can then be expressed as

(6 + 8i)(3 - 4i) ← expand using FOIL

= 18 - 24i + 24i - 32i² [ i² = ([tex]\sqrt{-1}[/tex] )² = - 1 ]

= 18 - 24i + 24i + 32 ← collect like terms

There are three solutions of the equation ||2x-3|-m|=m have if m>0.

We have to estimate the number of solutions of the equation ||2x - 3| - m| = m where m > 0.

As we know in the modulus function

|x|= x if x>0

     -x if x<0

      0 if x=0

here given m > 0

if |2x-3|-m>0 then the modulus value will be ||2x-3|-m|=  |2x-3|-m

Then, |2x - 3| - m = m

⇒|2x - 3| = m+m= 2m

⇒2x - 3 = 2m    or      -(2x-3)=2m

⇒2x - 3 = 2m    or      2x-3=-2m

⇒2x = 3 ± 2m

⇒x = (3 ± 2m)/2

⇒x= (3 + 2m)/2  or   (3 - 2m)/2

If  |2x-3|-m<0 then then the modulus value will be | |2x-3|-m| = -(|2x-3|-m)

-(|2x-3|-m)=m

⇒m-|2x-3|=m

⇒-|2x-3|= m-m

⇒ |2x - 3| = 0

⇒2x = 3

⇒x = 3/2

Therefore The solution of the equation will be (3 + 2m)/2, (3 - 2m)/2, and 3/2.

Therefore there are three solutions of the equation ||2x-3|-m|=m have if m>0.

In contrast to intuition or guessing, objective probability refers to the chances or odds that an event will occur based on the examination of certain measurements. Each metric is based on factual observation, a documented observation, or a long history of data collection.

Instead of being dependent on anecdotes, firsthand knowledge, or hunches, the objective probability is based on statistics, experiments, and mathematical measures. Using objective probability is crucial in the realm of finance to prevent making irrational investment decisions.

The largest possible volume of the given box is; 96.28 ft³

Let b be the length and the width of the base (length and width are the same since the base is square).

Let h be the height of the box.

The surface area of the box is;

S = b² + 4bh

We are given S = 100 ft². Thus;

b² + 4bh = 100

h = (100 - b²)/4b

Volume of the box in terms of b will be;

V(b) = b²h = b² * (100 - b²)/4b

V(b) = 25b - b³/4

The volume is maximum when dV/db = 0. Thus;

dV/db = 25 - 3b²/4

25 - 3b²/4 = 0

√(100/3) = b

b = 5.77 ft

Thus;

h = (100 - (√(100/3)²)/4(5.77)

h = 2.8885 ft

Thus;

Largest volume = [√(100/3)]² * 2.8885
