Answer:

After factoring we get:

[tex](\mathbf{2}q^2r+\mathbf{3}s^2t)(\mathbf{4}q^4r^2-\mathbf{6}q^2rs^2t+\mathbf{9}s^4t^2)[/tex]

Step-by-step explanation:

The expression given is:

[tex]8q^6r^3+27s^6t^3[/tex]

We need to factor the expression using the formula:

[tex]a^3+b^3=(a+b)(a^2-ab+b^2)[/tex]

Given the expression:

we have

[tex]a = 2q^2r\\b= 3s^2t[/tex]

Now applying the formula:[tex]a^3+b^3=(a+b)(a^2-ab+b^2)[/tex]

[tex](2q^2r)^3+(3s^2t)^3\\=(2q^2r+3s^2t)((2q^2r)^2-(2q^2r)(3s^2t)+(3s^2t)^2)\\=(2q^2r+3s^2t)(4q^4r^2-6q^2rs^2t+9s^4t^2)[/tex]

So, after factoring we get:

[tex](\mathbf{2}q^2r+\mathbf{3}s^2t)(\mathbf{4}q^4r^2-\mathbf{6}q^2rs^2t+\mathbf{9}s^4t^2)[/tex]

[tex]\large\boxed{\boxed{\pink {\bf \leadsto The \ equation \ represents \ a \ circle. }}}[/tex]

Given equation to us is ,

[tex]\green{\implies x^2 + y^2 - 8x + 10y + 15 = 0 }[/tex]

And we need to find which conic section does the equation below describe . So for that let's simpify the Equation .

[tex]\implies x^2 + y^2 - 8x + 10y + 15 = 0 \\\\\implies x^2 - 8x + y^2 + 10y = (-15) \\\\ \implies x^2 -8x + 4^2 - 4^2 + y^2 + 10y + 5^2-5^2 + 15 = 0\\\\ \implies (x -4)^2 + (y+5)^2 - 16 - 25 + 15 = 0 \\\\ \implies (x -4)^2 + (y+5)^2 - 26 = 0 \\\\\implies (x-4)^2 + (y+5)^2 = 26 \\\\\implies (x-4)^2+(y+5)^2=(\sqrt26)^2 [/tex]

And this is similar to the standard equation for a circle is ( x - h )² + ( y - k )²= r² , where ( h, k ) is the center and r is the radius.

Answer:

(1/2) ( 5 - 7x)  = 8 - 4x - 6

(1/2) (5 - 7x)  = 2 - 4x    multipy through by 2

5 - 7x   = 4 - 8x         add 8x  to both sides.......subtract 5 from both sides

x = -1

Answer:

Number of sedans on the ship = 99

Step-by-step explanation:

Given that:

Ratio of sedans to station wagons = 11 : 2

Number of station wagons count by Tom = 18

Number of sedans = x

Ratio of sedans to station wagons = x : 18

The relationship is directly proportional;

11 : 2 :: x : 18

Product of mean = Product of extreme

2x = 11*18

2x = 198

Dividing both sides by 2

[tex]\frac{2x}{2}=\frac{198}{2}\\x=99[/tex]

Hence,

Number of sedans on the ship = 99

Answer:

5

Step-by-step explanation:

The average (mean) is equal to the sum of all the data values divided by the number of values in the data set.

Mean = Sum / Count

Mean = (2+4+5+6+8) / 5

Mean = 25 / 5

Mean = 5

The average mean of the given data will be "5". A further solution is provided below.

The given data is:

→ [tex]2,4,5,6,8[/tex]

Total number of data value,

= 5

The mean will be:

= [tex]\frac{Sum \ of \ all \ data \ values}{Number \ of \ data \ values}[/tex]

By substituting the given values, we get

= [tex]\frac{2+4+5+6+8}{5}[/tex]

= [tex]\frac{25}{5}[/tex]

= [tex]5[/tex]

Thus the above is the correct answer.

A: -1/3x

Step-by-step explanation:

We can convert -1/3 to -2/6 by multiplying -1/3 by 2/2. As we know, 5-2 is 3. That makes 3/6. 3/6 is equivalent to 1/2. That means it has to be A.

Answer:

y+8=-5(x-3)

Step-by-step explanation:

The formula for point-slope form is y-y1=m(x-x1)

The points for (x1, y1) are (3, -8), meaning that 3 is x1 and -8 is y1.

So, start by writing your equation like this: y--8=m(x-3)

For the equation y--8=m(x-3), the y--8 will change to a + sign because two negatives make a positive, right? So, the equation should now look like this: y+8=m(x-3).

We know that the slope (m) is -5. Plug that into the equation to get this: y+8=-5(x-3)

And there you have it!! The equation is now in point-slope form!!

y+8=-5(x-3) is the final answer!!
