21. How many times larger is the volume of a cone if the height is multiplied by 3?

Answers

The volume of a cone increases by a factor of 27 when its height is multiplied by 3, as the volume of a cone scales with the cube of its linear dimensions.

The question asks how many times larger the volume of a cone becomes if its height is multiplied by 3. The volume of a cone is given by the formula V = ([tex]\frac{1}{3}[/tex]1/3)πr²h, where r is the radius and h is the height. If you multiply the height by 3, the volume will increase by a factor of 3 since volume scales with the third power of the linear dimensions. Therefore, the new volume would be 3³, or 27 times the original volume. This result can also be demonstrated by the mathematical expression Vnew = ([tex]\frac{1}{3}[/tex])πr²(3h) = 27Voriginal.

Please someone help me

Answers

Answer: Third option.

Step-by-step explanation:

When you divide fractions you can multiply the first fraction by the reciprocal of the second fraction.

To find the reciprocal of the fraction, you need to flip it. Then the original denominator will be the new numerator and the original numerator will be the new denominator.

Then, the reciprocal of the fraction [tex]\frac{1}{3}[/tex] is:

 [tex]\frac{3}{1}=3[/tex]

Therefore, you can find the quotient of [tex]8[/tex]÷[tex]\frac{1}{3}[/tex]  by multiplying [tex]8[/tex] by [tex]3[/tex]:

[tex]8[/tex]÷[tex]\frac{1}{3}=8*3=24[/tex]

When dividing fractions these are the steps you will take:

1. The first number in the expression stays the same (if it is a whole number then you may just place a one in the denominator and keep the numerator as the whole number like so)

[tex]\frac{8}{1}[/tex] ÷ [tex]\frac{1}{3}[/tex]

2. Change the division sign into a multiplication sign

[tex]\frac{8}{1}[/tex] × [tex]\frac{1}{3}[/tex]

3. Take the reciprocal (switch the places of numerator and denominator) of the second number in the expression

[tex]\frac{8}{1}[/tex] × [tex]\frac{3}{1}[/tex]

4. Multiply across

[tex]\frac{8*3}{1*1}[/tex]

As you can see to find the quotient of [tex]\frac{8}{1}[/tex] ÷ [tex]\frac{1}{3}[/tex] you must multiply 8 by 3 (C)

True or false? In a mapping diagram, a relation that is a function can have two arrows coming from the same input value.

Answers

Answer:

false

Step-by-step explanation:

In a mapping diagram, a relation that is a function can have two arrows coming from the same input value

false

Answer: False.

Step-by-step explanation:

By definition, a relation is a function if each input value has only one output value.

Knowing this, we can say that in a mapping diagram, a function will never have two arrows coming from the same input value.

 In other words, if in a mapping diagram a relation has two arrows coming from the same input value, this means that this input value has two output values, and according to the definition mentioned above, this relation cannot be a function.

Therefore, the statement "In a mapping diagram, a relation that is a function can have two arrows coming from the same input value", is FALSE.

What is the range of the following data set?

7.7, 8.4, 9, 8, 6.9


0.8


2.1


0.4


1.4

I am pretty sure its 2.1

Answers

The range is given by: largest number in the data set - smallest number in the data set.

In our case, the largest value is 9 and the smallest value is 6.9. Therefor:

Range = 9 - 6.9 = 2.1

Thus, you have correctly identified the answer as the second choice (2.1). It is easy to get confused with much larger data sets but always keep in mind that the range is simply the largest value minus the smallest value. This makes sense since 'range' refers to the spread in something, for example if you were testing your vocal range you would find the highest note you could sing and the lowest note - this is the same here, we are just finding the range of a data set instead.

Answer:

The correct answer is second option

2.1

Step-by-step explanation:

Points to remember

Range of a data set

The range of a data set means that, the difference between the highest and lowest value of the data set.

To find the range of data set

It is given that, a data set

7.7, 8.4, 9, 8, 6.9

Highest value = 9 and lowest value = 6.9

Range = Highest value - lowest value

 = 9 - 6.9 = 2.1

Therefore the correct answer is second option

If the slope of GH is −4/5 and the slope of HJ is 3/4, find the slope of JK so that GHJK is a parallelogram. quick answer pls

Answers

Answer:

Slope of JK = -4/5

Step-by-step explanation:

We know that GHJK is a parallelogram. If GHJK is a parallelogram then the sides of parallelogram will be:

GH, HJ, JK, GK

Hence the opposite sides will be:

GH and JK

HJ and GK

We know that opposite sides of parallelogram are parallel to each other and the slopes of parallel lines is equal.

So the slope of GH and JK will be equal.

And slopes of HJ and GK will be equal.

As we are given the slope of GH which is -4/5, the slope of JK will also be -4/5 because both lines are parallel.

Solve the equation x4 – 26x2 + 25 = 0 in the real number system.

Answers

Answer:

x = -1, 1, -5 , 5.

Step-by-step explanation:

x4 – 26x2 + 25 = 0

Factoring:

(x^2 - 25)(x^2 - 1) = 0

So x^2 - 25 = 0 gives x^2 = 25 and x = +/- 5.

x^2 - 1  gives  x^2 = 1 and x = +/- 1.

Follow below steps:

To solve the equation x4 − 26x2 + 25 = 0, we can use substitution to simplify the equation. Let's set u = x2, which turns our equation into a quadratic form: u2 − 26u + 25 = 0.

Now, we apply the quadratic formula where a = 1, b = -26, and c = 25 to find the values of u. The quadratic formula is u = (-b ± √(b2 - 4ac))/(2a). Substituting the values, we get the roots for u which are u = 25 and u = 1.

Now we substitute back for x by setting x2 = u, which gives us two separate equations to solve: x2 = 25 and x2 = 1. Solving these, we find the solutions for x to be x = 5, x = -5, x = 1, and x = -1.

An electrical tower casts a 120-foot shadow. At the same time, a 10-foot
street sign casts a shadow of 8 feet. What is the height of the tower?

Answers

Answer:

The height of the tower is 150 ft

Step-by-step explanation:

Let the height of the tower be H feet.

The corresponding sides will then be in the same proportion.

The ratio of the shadows will be in the same proportion as the ratio of the heights.

[tex]\frac{H}{10}=\frac{120}{8}[/tex]

We multiply both sides by 10 to get:

[tex]\frac{H}{10}\times 10=\frac{120}{8}\times 10[/tex]

[tex]H=150[/tex]

Therefore, the height of the tower is 150 ft

Answer:

Height of the tower = 150 foot

Step-by-step explanation:

We need to find height of the tower with 120-foot shadow.

We have a 10-foot  street sign casts a shadow of 8 feet.

[tex]\texttt{Ratio of height to shadow height =}\frac{10}{8}=\frac{5}{4}[/tex]

We have

       [tex]\frac{\texttt{Height of tower}}{\texttt{Shadow height of tower}}=\frac{5}{4}\\\\\frac{\texttt{Height of tower}}{120}=\frac{5}{4}\\\\\texttt{Height of tower}=\frac{5}{4}\times 120=150feet[/tex]

Height of the tower = 150 foot

The graph of y = ax 2 + bx + c is a parabola that opens up and has a vertex at (-2, 5). What is the solution set of the related equation 0 = ax 2 + bx + c?

Answers

Answer:

The solution set is ∅

Step-by-step explanation:

The expression

y = ax^2 + bx + c

is a quadratic equation.

The vertex is located at (-2, 5) and the graph opens up, this means that it never intercepts the x-axis.

The solution set is ∅

Please see attached image

Answer:

[tex]y=\frac{-5}{4}x^{2} -5b[/tex]

Step-by-step explanation:

Assume c = 0

Using the formula for the x-coordinate of the vertex, b can be calculated in terms of a:

[tex]x=\frac{-b}{2a} \\-2=\frac{-b}{2a} \\b=4a[/tex]

B can then be substituted into the quadratic equation, along with the coordinates of the vertex, to solve a:

[tex]y=ax^{2}+bx\\y=ax^{2}+4ax\\5=a(-2)^{2}+4(-2)a\\5=4a-8a\\5=-4a\\a=\frac{5}{-4}[/tex]

AND

[tex]b=4a\\b=\frac{-5}{4} *4\\b=-5[/tex]

Substituting into the quadratic equation:

[tex]y=\frac{-5}{4}x^{2} -5b[/tex]

Because a is negative, the parabola opens up.

If 2x + y = 6 and m - n = 2, what is the value of (4x + 2y)(4m - 4n)

Answers

Answer:

96

Step-by-step explanation:

If m - n = 2, then 4m - 4n = 4(m - n) = 4(2).

Then (4x + 2y)(4m - 4n) equals (4x + 2y)(8), or 8(4x + 2y).

But we are told that 2x + y = 6.  Multiplying all terms by 2, we get

4x + 2y = 12.  Substituting 12 for 4x + 2y, we get our final answer:

(4x + 2y)(4m - 4n) equals (4x + 2y)(8), or 8(4x + 2y), or 8(12) = 96

Answer:

96

Step-by-step explanation:

(4x + 2y)(4m - 4n) = ?

We have an equation

2x+y =6

Multiply it by 2

2(2x+y) = 2*6

Distribute

4x+2y = 12

Substitute 12 in for 4x+2y into the original problem

12(4m - 4n) = ?

We have an equation

m-n = 2

Multiply this by 4

4(m-n) = 4*2

Distribute

4m-4n = 8

Substitute 8 in for 4m -4n in 12(4m - 4n) = ?

12 * 8 = ?

For this case we have that if two lines are perpendicular, then the product of their slopes is -1.

If we have the following equation of the line:

[tex]y = -4x + 9[/tex]

The slope is [tex]m_ {1} = - 4[/tex]

Then yes:

[tex]m_ {1} * m_ {2} = - 1\\m_ {2} = \frac {-1} {m_ {1}}\\m_ {2} = \frac {-1} {- 4}\\m_ {2} = \frac {1} {4}[/tex]
