Line AB contains points A (−1, 3) and B (5, 3). Line AB has a slope that is zero undefined positive negative

It would be zero

See how the Y are the same so if you were to graph it you would get a flat line and it wouldn't be undefined cause that when the X has the same value.

Answer:

Slope of AB = 0

Step-by-step explanation:

There two points of a line AB, A(-1, 3) and B(5, 3). Since slope a line is represented by m = $\frac{y-y'}{x-x'}$

Now we place the values,

$m=\frac{3-3}{-1-5}=-\frac{0}{5}$

Therefore slope of line AB is zero.

We should never get confused with the sign whether it is positive or negative.

Zero is neither negative nor positive.

Answer will be slope of AB is zero.

How would I do this question.

Answer:

The density of cube is 6.17959 $\frac{g}{cm^{3} }$

Step-by-step explanation:

The density is given by ration of a mass of body and volume occupied by a body.

$\rho = \frac{m}{V}$

Where,

$\rho$ is density.

m is mass of a body

V is the volume of a body

Given that one side of the cube is 0.53cm

Hence, the volume of a body is V= $0.53^{3}$ =0.148877 $cm^{3}$

Now, the Density of the cube will be

$\rho = \frac{m}{V}$

$\rho = \frac{0.92}{0.148877}$

$\rho =6.17959$

Thus, The density of cube is 6.17959 $\frac{g}{cm^{3} }$

The area of a rectangle whose perimeter is a fixed 80 feet is given by A=40w - w2 , where w is the width of the rectangle. Deter

Stolb23 [73]

Answer:

Width=20 feet

Since Length=Width=20 feet, the rectangle is a Square.

Step-by-step explanation:

Area, $A=40w - w^2$

To determine the width of the rectangle that gives the maximum area, we take the derivative of A and solve for its critical point.

$A'=40 - 2w\\$When A'=0\\40-2w=0\\40=2w\\w=20 feet$

The width of the rectangle that gives the maximum area =20 feet.

Perimeter of a rectangle=2(l+w)

Perimeter of the rectangle=80 feet

2(l+w)=80

2l+2(20)=80

2l=80-40

2l=40

l=20 feet

Since the length and width are equal, the special type of rectangle that produces this maximum area is a Square.
