Answer:

( 3x + 1 ) × ( 2x^2 + 2x - 3 )

Step-by-step explanation:

= 6x^3 + 2x^2 + 6x +2x - 9x - 3

= 2x^2 × ( 3x +1 ) + 2x × ( 3x + 1 ) - 3 ( 3x + 1 )

= ( 3x + 1 ) × ( 2x^2 + 2x - 3 )

Which equation is correct for ∆FON?

lbvjy [14]

the picture in the attached figure

we know that

in the right triangle FON

sin F=opposite side angle F/hypotenuse

in this problem

opposite side angle F=ON--------> 9 units

Hypotenuse=FN--------> 18 units

sin F=ON /FN-------> sin F=9 /18

therefore

the answer is the option

B.) sin F 9/18

Complete the equation of the line through ( 4 , -8 ) and ( 8 , 5 )

irinina [24]

Answer:

Therefore the equation of the line through ( 4 , -8 ) and ( 8 , 5 ) is

13x - 4y = 84.

Step-by-step explanation:

Given:

Let,

point A( x₁ , y₁) ≡ ( 4 ,-8)

point B( x₂ , y₂) ≡ (8 , 5)

To Find:

Equation of Line AB =?

Solution:

Equation of a line passing through Two points A( x₁ , y₁) and B( x₂ , y₂)is given by the formula

$(y - y_{1} )=(\frac{y_{2}-y_{1} }{x_{2}-x_{1} })\times(x-x_{1}) \\$

Substituting the given values in a above equation we get

$(y-(-8))=(\frac{5-(8)}{8-4})\times (x-4)\\ \\(y+8)=\frac{13}{4}(x-4)\\\\4(y+8)=13(x-4)\\4y+32=13x-52\\13x-4y=84...............\textrm{which is the required equation of the line AB}$

Therefore the equation of the line through ( 4 , -8 ) and ( 8 , 5 ) is

13x - 4y = 84.

A mine extracts 2 metric tons of coal in an hour. The mine uses 14 ton of the extracted coal every hour to generate electricity

olga nikolaevna [1]

This sounds like a very poor business model right from the beginning.
The mine continuously operates at a loss, and it has nothing to sell.

If it uses 14 tons an hour just to keep running, and it produces 2 tons
an hour, then it doesn't take a business genius to point out that this
operation is rapidly digging itself straight into the ground.

I'm guessing that there was a major mistake made during the copying
of the problem.
