is the following relation a function (1 point)
-101

Answer:

8

Step-by-step explanation:

x = 2/x <=== It must be: x ≠ 0. Solve for x. Multiply both sides by x.

x^2 = 2.

Hence:

x = ±√2.

Both -√2 and √2 give 8 when they are raised to the power of 6.

(-√2)^6 = (√2)^6 = 8.

The value of the given expression [tex]x^6[/tex] is 8 and this can be determined by using the arithmetic operations.

Given :

A number x is twice its reciprocal.

The following steps can be used in order to determine the value of [tex]x^6[/tex]:

Step 1 - The arithmetic operations can be used in order to determine the value of [tex]x^6[/tex].

Step 2 - The mathematical expression of the given statement "A number x is twice its reciprocal" is:

[tex]x = \dfrac{2}{x}[/tex]

Step 3 - Simplify the above expression in order to determine the value of 'x'.

[tex]x = \pm\sqrt{2}[/tex]

Step 4 - Now, substitute the value of 'x' in the given expression.

[tex]x^6= (\sqrt{2} )^6\\x^6 = 8[/tex]

So, the value of the given expression [tex]x^6[/tex] is 8.

Answer:

Homework #1-18: Answer yes or no, if no give the reason

1) Is A ⊆ B given A = silver, B = {gold, silver, diamond}

A is not a set, so it can’t be a proper subset.

Answer: no, because A is not a set

3) Is C ⊆ D given C = {Phoenix}, D = {Phoenix, Glendale, Peoria, Scottsdale}

I need two rules to work.

C is a set so rule 1 is satisfied.

Every element of C is also an element of D, so rule 2 is satisfied.

Answer: yes

5) Is A ⊆ B given A = {2,3} , B = {1,2,3,4,5}

I need two rules to work.

A is a set so rule 1 is satisfied.

Every element of A is also an element of B, so rule 2 is satisfied.

Answer: yes

7) Is A ⊆ B given A = a, B = {| }

A is not a set, so it can’t be a proper subset.

Answer: no, because A is not a set

9) Is A ⊆ B given A = { }, B = {1,2,3,4,5}

Answer yes: the empty set is a subset of every set.

11) Is S ⊂ T given, S= ∅, T = {1,2,3,4,5}

Answer yes: the empty set is a subset of every set.

13) Is A ⊂ B given A = {1,2,3}, B = {3,2,1}

This is not a true statement. The sets are equal and this symbol does not allow sets to be equal.

Answer: no, sets are equal

15) Is C ⊂ D given C = {1,2,3,4,5}, D = {1,2,3,4}

Answer: no, C is not contained in D, so this is not true

17) Is A ⊂ B given A = {4,3,2,1 }, B = {1,2,3,4,5}

A is a set so rule 1 is satisfied,

A is contained in B so rule 2 is satisfied

A is not equal to B so rule 3 is satisfied

Answer: yes (all 3 rules are satisfied)

Step-by-step explanation:

In this problem we are expected to solve for the time taken for the second person to meet with the first.

given that

first person's speed=0.2mph

let time taken be= x

we know that

velocity= distance/time

0.2=distance/x

distance=0.2x----1

second person's speed= 0.25mpm

time taken=x-1

we know that

velocity= distance/time

0.25=distance/x-1

distance=0.25(x-1)

distance=0.25x-0.25-----2

equating equation 1 and 2 we have

0.2x=0.25x-0.25

0.2x-0.25=-0.25

-0.05x=-0.25

divide both sides by -0.05 we have

x=-0.25/-0.05

x=5

we know that the second person's time is described by

=x-1

=5-1=4min

The second person will catch up after 4 minutes

Answer: 5/153

Step-by-step explanation:

Well, you'd just have to plug in 40 for n.

5/(40*4 - 7) = m

5/(160-7) = m

5/153 = m

An equation is formed of two equal expressions. As per the literal equation m=5/4n-7, the value of m when the value of n is 7 is 42.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The value of m from the given equation can be found by substituting the value of n as 7 in the given equation as shown below.

m = (5/4)n - 7

Substitute the value of n as 40,

m = (5/4)40 - 7

m = (5/1)10 - 7

m = 50 - 7

m = 42

Hence, as per the literal equation m=5/4n-7, the value of m when the value of n is 7 is 42.

Answer:

Speed of Jennifer on Sunday [tex]=45[/tex] mi/hr

Step-by-step explanation:

Let speed of Jennifer on Saturday be x mi/hr

On Saturday morning, it took Jennifer 3.6 hours to drive to her mother's house for the weekend.

Distance travelled by Jennifer on Saturday = Speed × Time [tex]=3.6x[/tex] miles

Speed of Jennifer on Sunday = [tex](x-5)[/tex] mi/hr

On Sunday evening, due to  heavy traffic, it took Jennifer 4 hours to return home.

Distance travelled by Jennifer on Sunday = Speed × Time [tex]=4(x-5)[/tex] miles

As distance is obviously same on both Saturday and Sunday,

[tex]3.6x=4(x-5)\\3.6x=4x-20\\20=4x-3.6x\\20=0.4x\\x=\frac{20}{0.4}\\ x=50[/tex]

Therefore,

Speed of Jennifer on Sunday = [tex](50-5)=45[/tex]  mi/hr

Step-by-step explanation:

Answer:

26 coaches and 143 players

Step-by-step explanation:

we can set up a proportion: [tex]\frac{coaches}{players}[/tex]

Our original proportions, 4/22 and 2/11 simplify to 2/11

We basically need a proportion that simplifies to 2/11, So let's simplify each proportion

24 coaches and 120 players: 24/120 simplified ⇒ 1/5

26 coaches and 143 players: 26/143 simplified ⇒ 2/11

28 coaches and 168 players: 28/168 simplified ⇒ 1/6

30 coaches and 180 players: 30/180 simplified ⇒ 1/6

The porportion, 26 coaches and 143 players simplifies to our orginal

proportion, 2/11, therefore it is proportional

[tex]5.50c+5.50a[/tex]

Step-by-step explanation:

Cost of 1 ticket = $5.50

Total number of children who brought tickets = c

Total number of adults who bought tickets = a

Amount earned from selling tickets to children = 5.50 c

Amount earned from selling tickets to adults = 5.50 a

Therefore,

Total money earned by the company from the sale of tickets = [tex]5.50c+5.50a[/tex]

Answer:

The formula which should be used is  [tex]m=\frac{E}{c^{2}}[/tex] ⇒ A

Step-by-step explanation:

To solve an equation of different variables to one of these variables do that

Let us do that with the question

∵ E = mc²

→ E is the total energy

→ m is the total mass

→ c² is the speed of light

∵ We need to solve the equation for the total mass m

→ We need to take c² to the other side

∵ c² is multiplied by m

∴ Divide both sides by c² to move it from the right side to the left side

∴ [tex]\frac{E}{c^{2}}=\frac{mc^{2}}{c^{2}}[/tex]

→ Cancel c² with c² on the right side

∴ [tex]\frac{E}{c^{2}}=m[/tex]

→ Switch the two sides

∴ [tex]m=\frac{E}{c^{2}}[/tex]

The formula which should be used is  [tex]m=\frac{E}{c^{2}}[/tex] ⇒ A

Answer:qsq

Step-by-step explanation:

Answer:

Step-by-step explanation:

The answer to this is 1 or 7:

To find the range for the number of measures played to satisfy our solution, we must solve for x using s = 80.

Next, we subtract 50 from both sides of the equation.

Next, we divide both sides of the equation by 10

Next, to eliminate the absolute value bars, we will add a ± sign in front of our s value, 3.

Finally, we add 4 to both sides of our equation giving us 4 ± 3 = x

Separating this into two equations, we get 4 - 3 = x and 4 + 3 = x

Therefore, x, the number of measures of music played, must be either 1 or 7.

Answer:

[tex]\displaystyle y=-\frac{a}{b}x+\frac{c}{b}[/tex]

Step-by-step explanation:

The equation of the line, expressed in slope-intercept form is:

[tex]y=mx+y_o[/tex]

Where m the slope and yo the y-intercept.

Since we are given the line in standard form:

ax+by=c

To find the slope-intercept form, we just solve it for y:

[tex]\boxed{\displaystyle y=-\frac{a}{b}x+\frac{c}{b}}[/tex]

Comparing the last equation with the slope-intercept form:

[tex]\displaystyle m=-\frac{a}{b}[/tex]

[tex]\displaystyle y_o=\frac{c}{b}[/tex]

Answer:

ax + by = c

-ax     -ax

by=ax+c

then dived both sides by b to get y by itself

y= a/bx +c

Answer

1360

Step-by-step explanation:

4x10 is 40 so you'd have to multiply 40x34 which is 1360

136×10 is the amount of water used by the airplane to deliver 34

trips.

Multiplication is a method of finding the product of two or more numbers

Given that Airplanes are sometimes used to fight fires.

A certain airplane can deliver 4 x 10 liters of water in one trip.

We need to find how much water can the  airplane deliver in 34

trips

Let us find the water used for one trip.

1 trip is 4 x 10 liters which is 40 litres.

Now we have to find for 34 trips.

We have to multiply 34 with 40 litres

34×40

Thirty four times forty

1360

Now we have to convert it to the scientific notation 136×10

Hence, 136×10 is the amount of water used by the airplane to deliver 34

trips.
