Answer:

Range of the relation is,  {1 , 0, -1}

Step-by-step explanation:

Given: Relation R = {(-4, 1), (-2, 0) , (8, -1)}

To find the range of the relation R;

In the set of ordered pairs, the domain is the set of the  first number in every pair, and the range is the set of the second number of all the pairs.

Then;

Domain of the relation: {-4, -2, 8}

Range of the relation is; {1 , 0, -1}

therefore, the range of the relation is,  {1 , 0, -1}

The range of the given relation is {-1, 0, 1}

The range of a relation refers to the set of all possible output values of the relation. In this case, the relation consists of three ordered pairs: (-4, 1), (-2, 0), and (8, -1). To find the range, we need to determine the set of all possible second values (y-values) in the ordered pairs. The range of the relation is {-1, 0, 1}.

Hello from MrBillDoesMath!

Answer:

No. That problem cited is one of 3 great unsolved problems of antiquity. See  https://en.wikipedia.org/wiki/Angle_trisection for details.

P.S.  I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!

Answer:

NO , an angle is not trisected using only a compass and a straight  edge.

Step-by-step explanation:

We are given two tools a compass and a straight edge

We need to tell if an angle is trisected using them or not.

Answer is NO , an angle is not trisected using only a compass and a straight  edge.

When we draw a semicircle by point pointer of compass at vertex of angle and then draw a line using points we get when semicircle intersects the arms of the angle. We get angle Bisection.

We again try to bisect we get four equal angles not Three.

So It is impossible to make odd numbers of equal angles from a given angle using a compass and a straight edge.

AB corresponds to AC. Both are the left diagonal lines of triangle ABE and triangle ACD. Both AB and AC are also the first two letters of ABE and ACD respectively

BE and CD correspond as well. They are the horizontal sides of the two triangles. BE and CD are the last two letters of ABE and ACD.

Set up the proportion below. Then solve for x

AB/AC = BE/CD

AB/(AB+BC) = BE/CD

x/(x+3) = 2/5

5x = 2(x+3)

5x = 2x+6

5x-2x = 6

3x = 6

x = 2

Answer: AB = 2

note how AB = x = 2, so AC = AB+BC = x+3 = 2+3 = 5. This forms the ratio AB/AC = 2/5 which is identical to the ratio BE/CD = 2/5

To find the value of AB in the similar triangles ABE and ACD, use the ratio of the corresponding sides.

Given that ∆ABE is similar to ∆ACD, we can write the ratio of the corresponding sides: AB/AC = AE/AD = BE/CD. Note that corresponding sides of similar triangles are proportional. Therefore, the value of AB can be determined by the ratio AB/AC.

For example, if the length of AC is 10 units and the ratio AB/AC is 3/5, we can find the length of AB by multiplying 10 by 3/5: AB = (3/5) * AC = (3/5) * 10 = 6 units.

So, the value of AB depends on the specific information given about the ratios of the sides of ∆ABE and ∆ACD.

Answer:

Approximately 20 complete pieces of 1 3/4 foot of ribbon can be obtained.

Step-by-step explanation:

You have a piece of ribbon 36 feet long that should be divided into pieces of 1 [tex]\frac{3}{4}[/tex] feet. In order to know the quantity of pieces of said measurement, the total length of the ribbon (36 feet) must then be divided by the desired measurement of each of the pieces (1 3/4 feet):

[tex]amount of pieces of ribbon=\frac{36}{1 \frac{3}{4} }[/tex]

1 [tex]\frac{3}{4}[/tex] is a mixed number. A mixed number or mixed fraction consists of a whole part (natural number) and a fractional part. All fractions greater than unity can be expressed as a mixed number.

To be able to make the division stated previously, it is convenient to pass the mixed number to an improper fraction (An improper fraction is a fraction in which the numerator is greater than or equal to the denominator). For this you multiply the denominator by the whole number. To the result, you must add the numerator. Then that number is placed over the original denominator. Expressed in general is:

[tex]a \frac{b}{c} =\frac{a*c+b}{c}[/tex]

In this case:

[tex]1 \frac{3}{4} =\frac{4*1+3}{4}=\frac{7}{4}[/tex]

Then the previously stated division is expressed as:

[tex]\frac{36}{\frac{7}{4} }[/tex]

One way to perform this division is to reverse the SECOND FRACTION, that is, change the denominator to the numerator and change the numerator to the denominator. Then, both numbers are multiplied.

[tex]\frac{36}{\frac{7}{4} } =36*\frac{4}{7}[/tex]

Given that 36 can be expressed as 36/1, the multiplication is done "online." That is, the numerator of the first fraction by the numerator of the second and the denominator of the first fraction by the denominator of the second.

[tex]\frac{36}{1} *\frac{4}{7} =\frac{36*4}{1*7} =\frac{144}{7}[/tex]

Now it will be passed from fraction to mixed number. For that, the numerator is divided by the denominator. The quotient of the division becomes the integer of the mixed number. The rest of the division is the numerator of the fraction. The denominator is the same as that of the fraction, being the divisor of the division.

When dividing 144 by 7 the quotient is 20, the remainder is 4 and the divisor is 7. Then the mixed number formed is [tex]20 \frac{4}{7}[/tex]

This indicates that approximately 20 complete pieces of 1 3/4 foot of ribbon can be obtained.

Correct.

Answer:

x=-5, y=-2

Step-by-step explanation:

6x+ 28 =y

5x-y=-23

Substitute 6x+28 in for y in the second equation

5 x-(6x+28)=-23

Distribute the negative sign

5x -6x-28 = -23

-x -28 = -23

Add 28 to each side

-x-28+28 = -23+28

-x = 5

Multiply by -1

x = -5

Now we need to solve for y

y = 6x+28

Substitute x=-5

y = 6(-5) + 28

y = -30+28

y = -2

arc length = circumference × fraction of circle

                 = 84 ×[tex]\frac{90}{360}[/tex] = 21 cm

The answer would be  (3/8) (d+2)

The expression 3/8d + 3/4 is factored by first factoring out the common factor of 3, resulting in the factored form 3*(1/8d + 1/4).

The student's question involves the factoring of a linear algebraic expression. The given expression is 3/8d + 3/4, where 'd' is a variable. To factor this expression, we need to look for common factors in each term. Here, both terms contain a factor of 3, which we can factor out. This results in:

Thus, the fully factored expression is 3/8d + 3/4 = 3*(1/8d + 1/4), with the understanding that 1/4 has been converted to 2/8 to have a common denominator.

Answer:

Step-by-step explanation:

Given is a polynomial in x

[tex]F (x)= x^4 + 12x^3 + 30x^2 - 12x + 70[/tex]

We have to find the remainder when the above polynomial is divided by x+5

Remainder theorem says that f(x) gives remainder R when divided by polynomial x-a means f(a) = R

Applying the above theorem we can say that value of the function when x =-5

= Remainder when f is divided by x+5

= F(-5)

Substitute the value of -5 in place of x

= (-5)^4 + 12(-5)^3 + 30(-5)^2 - 12(-5) + 70

= 625-1500+750+60+70

= 5

Hence answer is 5

Answer:

[tex]f(-5)=[/tex] 5

Step-by-step explanation:

According to the polynomial remainder theorem, when a polynomial f(x) is divided by a linear polynomial (x - a), the remainder of that division will be equal to f(a).

Therefore, substituting the value of x as -5 in the given function to find its value:

[tex]f(x)[/tex] = [tex]x^4 + 12x^3 + 30x^2 - 12x + 70[/tex]

[tex]f(-5)[/tex] = [tex](-5)^4 + 12(-5)^3 + 30(-5)^2 - 12(-5) + 70[/tex]

[tex]f(-5)[/tex] = [tex]625+(-1500)+750-(-60)+70[/tex]

[tex]f(-5)[/tex] = [tex]5[/tex]

Therefore, the value of the given function when x = -5 is 5.

Answer:

8 , 20, 50, 125, 625/2           option D

Step-by-step explanation:

Given that,

first term a₁ = 8

common ratio (r) = [tex]\frac{5}{2}[/tex]

We need to find the five  terms of the geometric progression

We know that the nth term formula :

aₙ = a₁rⁿ-¹

where a₁ is first term and r is the common ratio

n is the number of terms

Second term (n=2)

a₂ = 8*[tex](\frac{5}{2} )^{2-1}[/tex] = [tex]\frac{8*5}{2}[/tex] = 20

Third term (n = 3)

a₃ = 8*[tex](\frac{5}{2} )^{3-1} = 8*(\frac{5}{2} )^{2}  = (\frac{8*25}{4} ) = 50[/tex]

Forth term (n=4)

a₄ = [tex]8(\frac{5}{2} )^{4-1} = 8*(\frac{5}{2} )^{3}  = (\frac{8*125}{8} ) = 125[/tex]

Fifth term (n=5)

a₅ = [tex]8(\frac{5}{2} )^{5-1} = 8*(\frac{5}{2} )^{4}  = (\frac{8*625}{16} ) = \frac{625}{2}[/tex]

So, five terms are :

8 , 20, 50, 125, 625/2

Final answer:

Bailey spends more time getting dressed, which is 1/2 of an hour (30 minutes), whereas she spends 1/4 of an hour (15 minutes) eating breakfast.

Explanation:

The question is asking which activity Bailey spends more time on in the morning: getting dressed or eating breakfast. Since Bailey has an hour to get ready, 3/6 of an hour is spent getting dressed, and 1/4 of an hour is spent eating breakfast.

First, we simplify the fraction for getting dressed, as 3/6 can be reduced to 1/2. Thus Bailey spends 1/2 hour or 30 minutes getting dressed. To find how much time is spent eating breakfast, we calculate 1/4 of an hour, which is 15 minutes.

Comparing the two, we see that Bailey spends more time getting dressed (30 minutes) than eating breakfast (15 minutes).
