Factor 24x^3y^2-4x^2y+84x^4 please show work

Answers

Answer 1

The given equation is :

[tex]24x^{3}y^{2} -4x^{2}y +84x^{4}[/tex]

Now taking [tex]4x^{2}[/tex] common from all the terms, we get

[tex]4x^{2} (6xy^{2} -y+21x^{2} )=0[/tex]

Writing the equation in standard form we get:

[tex]21x^{2} +6xy^{2} -y=0[/tex]

Now we will use the formula of quadratic equations to solve this,

[tex]x1,2 = \frac{-b+\sqrt{b^{2}-4ac }} {2a}[/tex] and

[tex]x1,2 = \frac{-b-\sqrt{b^{2}-4ac }} {2a}[/tex]

Now putting a = 21, b = 6y² and c = -y and solving the equations, we get

[tex]x=\frac{-6y^{2}+\sqrt{36y^{4}+84y }}{42}[/tex] and

[tex]x=\frac{-6y^{2}-\sqrt{36y^{4}+84y }}{42}[/tex]

the table shows how much jake charged for the last 4 orders of pup cakes. what is the constant of proportionality in cost per pup cake?

Answers

Answer:

$2.50

Step-by-step explanation:

Let's take a look at the 4 orders and check the price per pup cake in each order:

Order 1: $5 for 2 cakes, so $2.50 per cake.

Order 2: $7.50 for 3 cakes, so $2.50 per cake.

Order 3: $12.50 for 5 cakes, so $2.50 per cake.

Order 4: $20.00 for 8 cakes, so $2.50 per cake.

Jake has a very consistent pricing of his cakes... they're always $2.50 each.

That price is the relation between the price asked and the number of cakes sold, that's the constant of proportionality in this case.

Answer:

Option 3rd is correct

$2.5 is the constant of proportionality in cost per pup cake

Step-by-step explanation:

The direct proportionality states that:

[tex]y \propto x[/tex]

then the equation is in the form of :

[tex]y = kx[/tex]              ....[1]

where, k is the constant of proportionality.

As per the statement:

The table shows how much Jake charged for the last 4 orders of pup cakes.

Let y represents the cost  and x represents the pup-cakes

Consider any values of x and y from the given tables.

x = 3 and y = $7.5

To find constant of proportionality in cost per pup cake.

Substitute these in [1] we have;

[tex]7.5 = 3k[/tex]

Divide both sides by 3 we have;

2.5 = k

or

k = 2.5

Therefore, $2.5 is the constant of proportionality in cost per pup cake

if you horizontally stretch the quadratic parent function, f(x)=x^2, by a factor of 3, what is the equation of the new function?

Answers

Answer: [tex]g(x)=\frac{1}{9}x^2[/tex]

Step-by-step explanation:

By definition, he quadratic parent function [tex]f(x)=x^2[/tex] is the simplest form of a quadratic function.

By definition, if the fucntion is multiplied by the factor b and:

 |b|>0  the function is stretched.

If 0<|b|<1 the function is compressed.

Then the new function will have the form:

[tex]g(x)=(\frac{1}{b}x)^2[/tex]

Therefore, keeping the above on mind, if b=3, then the new function is:

[tex]g(x)=(\frac{1}{3}x)^2[/tex]

[tex]g(x)=\frac{1}{9}x^2[/tex]

Answer: g(x)=(1/3(x))^2

Besides 6 and 1, what is one factor of 6?

Answers

Three times two equals six

Another factor of 6, besides 6 and 1, is 3. Factors are numbers that divide into another number without leaving any remainder. Both 2 and 3 are factors of 6 since 2 multiplied by 3 equals 6.

Besides 6 and 1, another factor of 6 is 3.

Factors are whole numbers that divide evenly into another number. For the number 6, the factors are 1, 2, 3, and 6. The process of factoring involves finding all numbers that you can multiply together to get the number in question. In this case, 2 multiplied by 3 equals 6.

We can also verify this by noting that dividing 6 by 3 gives us 2 with no remainder, confirming that 3 is indeed a factor of 6.

Add -5x to both sides.

[tex]3y + 5x - 5x = - 5x + 4[/tex]

[tex]3y = - 5x + 4[/tex]

Divide through by 3.

[tex]y = - \frac{5}{3}x + \frac{4}{3} [/tex]

A circle is centered at the point -3 2 and passes through the point 1 and 5 the radius of the circle is blank units

Answers

Answer:

The radius of the circle is 5 units

Step-by-step explanation:

Given in the question,

centered point = (-3 , 2)

a point in the circle = (1,5)

To find the radius of circle we will use the circle equation

(x – h)² + (y – k)² = r²,

with the centre being at the point (h, k) and the radius being r.

Plug values in the equation

(1 – (-3))² + (5 – 2)² = r²

(1+3)² + (3)² = r²

4² + 3² = r²

25 = r²

r = √25

r = 5

The bases of a trapezoid are 20 and 32 feet. The height of the trapezoid is 6 feet

Answers

Answer:

The Answer is 156

Step-by-step explanation:

A=(B1+B2)H/2

1) to find the area of a trapezoid you must First add the 2 bases

20+32= 52

2) Then Multiply the 2 bases sum by the Height

52 x 6 = 312

3) divide the product 312 By 2

312/2= 156

That is Your answer!

Hopes this helps!

For the area of a trapezoid use formula: Area = (BaseX+BaseY) times Height divided by 2.

so for this problem you’d plug in (20+32) times 6 then divide it by two.

20+32=52 times 6 equals 312

Divide by 2 and you get 156.

Area= 156

Answers

pythagoras

a^2 = b^2 + c^2

a^2 = (8)^2 + (4)^2

a^2 = 64 + 16

a^2 = 80

[tex]a = \sqrt{80} [/tex]

Answer:

The length of the diagonal (d) = 4[tex]\sqrt{5}[/tex] units.

Step-by-step explanation:

We are given the length (l) = 8, width (w) = 4 and height (h) = 2.

Now we have to find the diagonal of the base.

The given figure is a rectangle box. The base of the rectangular box is a rectangle with the length (l) = 8 and the width(w) = 4

The length of the diagonal (d) = [tex]\sqrt{l^2 + w^2}[/tex]

d = [tex]\sqrt{8^2 + 4^2}[/tex]

d = [tex]\sqrt{64 + 16}[/tex]

d = [tex]\sqrt{80}[/tex]

d = [tex]\sqrt{16} \sqrt{5}[/tex]

d = 4[tex]\sqrt{5}[/tex]

So, the length of the diagonal (d) = 4[tex]\sqrt{5}[/tex] units.

Solve for x. |x| – 5 = 7

Answers

Answer:

x = 12

Step-by-step explanation:

x - 5 = 7

⇒ x = 7 + 5 = 12

Final answer:

To solve for x, add 5 to both sides of the equation and then determine the absolute value of x.

Explanation:

To solve for x in the equation |x| – 5 = 7, we need to isolate x on the left side of the equation. To do this, we can add 5 to both sides:

|x| – 5 + 5 = 7 + 5

|x| = 12

Now, we have an absolute value equation. The absolute value of a number is its distance from zero. Therefore, we have two possible solutions: x = 12 or x = -12.

Which of these functions has an inverse function? Select all that apply.
y = x
y = x^2
y = x^3
y = x^4

Answers

ANSWER

y=x

y=x³

EXPLANATION

A function, f(x) has an inverse if and only if

[tex]f(a) = f(b) \Rightarrow \: a = b[/tex]

Thus, the function is one to one.

For y=x or

[tex]f(x) = x[/tex]

[tex]f(a) = f(b) \Rightarrow \: a = b[/tex]

Hence this function has an inverse.

For the function y=x² or f(x)=x².

[tex]f(a) = f(b) \Rightarrow \: {a}^{2} = {b}^{2} \Rightarrow \: a = \pm \: b[/tex]

This function has no inverse on the entire real numbers.

For the function y=x³ or f(x)=x³

[tex]f(a) = f(b) \Rightarrow \: {a}^{3} = {b}^{3} \Rightarrow \: a = b[/tex]

This function also has an inverse.

For y=x⁴ or f(x) =x⁴

[tex]f(a) = f(b) \Rightarrow \: {a}^{4} = {b}^{4} \Rightarrow \: a = \pm \: b[/tex]

This function has no inverse over the entire real numbers.

Answer:

The function [tex]x=y[/tex] and [tex]y=x^{3}[/tex] are inverse function.

Step-by-step explanation:

Function inverse definition:

If a provided function f(x) is mapped x to y, then the inverse of the provided function f(x) is mapped y to x.

Or  [tex]f(x)=f(y)\Rightarrow x=y[/tex]

Now, consider the function y = x.

Interchange the variables x and y.

[tex]x=y[/tex]

Now, solve [tex]x=y[/tex] for [tex]y[/tex].

[tex]x=y[/tex]

Therefore, this function has an inverse.

Consider the function [tex]y=x^{2}[/tex].

Interchange the variables x and y.

[tex]x=y^{2}[/tex]

Now, solve [tex]x=y^{2}[/tex] for [tex]y[/tex].

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

Therefore, the function has no inverse.

Consider the function [tex]y=x^{3}[/tex].

Interchange the variables x and y.

[tex]x=y^{3}[/tex]

Now, solve [tex]x=y^{3}[/tex] for [tex]y[/tex].

[tex]\sqrt[3]{x}=y[/tex]

Therefore, the function has inverse.

Consider the function [tex]y=x^{4}[/tex].

Interchange the variables x and y.

[tex]x=y^{4}[/tex]

Now, solve [tex]x=y^{4}[/tex] for [tex]y[/tex].

[tex]\pm \sqrt[4]{x}=y[/tex]

Therefore, the function has no inverse.

Hence, the function [tex]x=y[/tex] and [tex]y=x^{3}[/tex] are inverse function.

Which of the following is the solution to the following system of inequalities? Let the green region represent the solution set. X+2y<=4 3x-y>2

Answers

Answer:

See picture attached.

Step-by-step explanation:

To find the solution, graph each equation using the y = mx + b form.

Start by converting to this form.

x + 2y < 4 becomes y < -1/2x +2

3x - y > 2 becomes y < 3x - 2

Then mark each y-intercept. These points are (0,2) and (0,-2).

Using the slope mark the next points at (-1,4) and (1, -1) respectively.

Connect using dash lines since this is not equal to in either inequality.

Test a point no on either line like (-1,-1).

If the inequality holds true, shade the area.

Where the areas overlap is the solution. See picture.

Inequalities are used to represent unequal expressions.

The solution to the inequality is [tex]x \le \frac 87[/tex] and [tex]y < \frac{10}7[/tex]

The inequalities are given as:

[tex]x + 2y \le 4[/tex]

[tex]3x - y > 2[/tex]

Express both inequalities as equations'

[tex]x + 2y = 4[/tex]

[tex]3x -y = 2[/tex]

Make y the subject in [tex]3x -y = 2[/tex]

[tex]y = 3x - 2[/tex]

Substitute [tex]y = 3x - 2[/tex] in [tex]x + 2y \le 4[/tex]

[tex]x + 2(3x - 2) \le 4[/tex]

Open brackets

[tex]x + 6x - 4 \le 4[/tex]

[tex]7x - 4 \le 4[/tex]

Collect like terms

[tex]7x \le 4+4[/tex]

[tex]7x \le 8[/tex]

Divide both sides by 7

[tex]x \le \frac 87[/tex]

Substitute 8/7 for x in [tex]3x - y > 2[/tex]

[tex]3 \times \frac 87 - y > 2[/tex]

[tex]\frac{24}7 - y > 2[/tex]

Collect like terms

[tex]- y > 2 -\frac{24}7[/tex]

Take LCM

[tex]- y > \frac{14 -24}7[/tex]
