Answer:

428

160

12.7

Step-by-step explanation:

So I'm pretty sure all it's asking you do is divide the product (number on the right) by the number on the left!

So 42.8/ $\frac{1}{10}$ =428

1600/10=160

1.27/ $\frac{1}{10}$ =127

The volume of a box is given by the expression

Kamila [148]

Answer:

Area = x^2+4x+3

Step-by-step explanation:

The volume of a box is given by the expression

x^3 + 3x^2 - x-3. The height of the box is given by the expression x-1.

volume of the box = Length * width * height

L is the side length of the box;

Given

V(x) = x^3 + 3x^2 - x-3

Factorize

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

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

V(x) = (x+1)(x-1)(x+3)

V = LWH

V = Area * Width

Since the height of the box is x - 1

Area = (x+1)(x+3)

Expand

Area = x^2+3x+x+3

Area = x^2+4x+3

Select all the points that are on the line through LaTeX: (0,5)( 0 , 5 ) and LaTeX: (2,8)( 2 , 8 ). Group of answer choices LaTe

Ivenika [448]

Answer:

The points (4,11), (6,14), (30,50) lie on the line joining the points (0,5) and (2,8).

Step-by-step explanation:

The equation of the line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

So, the equation of the line passing through two points (0,5) and ( 2, 8 ) is

$y-5=\frac{8-5}{2-0}(x-0)$

$\Rightarrow y=1.5x+5\cdots(i)$

For the point (4,11), pout x=4 in equation (i), we have

$y=1.5\times4 +5=11$ , which is given y coordinate, hence this point (4,11) lies on the line.

For the point (5,10), pout x=5 in equation (i), we have

$y=1.5\times5 +5=12.5,$ which is not the given y coordinate, hence the point (5,10) doesn't lie on the line.

For the point (6,14), pout x=6 in equation (i), we have

$y=1.5\times6 +5=14$ , which is the given y coordinate, hence the point (6,14) lies on the line.

For the point (30,50), pout x=30 in equation (i), we have

$y=1.5\times30 +5=50$ , which is the given y coordinate, hence the point (30,50) lies on the line.

For the point (40,60), pout x=40 in equation (i), we have

$y=1.5\times40 +5=65$ , which is not the given y coordinate, hence the point (40,60) doesn't lie on the line.

Hence, the points (4,11), (6,14), (30,50) lie on the line joining the points (0,5) and (2,8).
