D) perpendicular!
A perpendicular's definition is: a straight line at an angle of 90° to a given line, plane, or surface.
And if you mark them on a graph you could see these two are opposite of each other.

Answer:

Perpendicular.

D is the correct option.

Step-by-step explanation:

The given equations are

y=4x+4\\\\y=-\frac{1}{4}x-4

The slope intercept form of a line is given by

y=mx+b

Here, m is the slope and b is the y intercept.

Comparing given equation with slope intercept form of the line

Slope of first line = 4

Slope of second line = -1/4

These two slopes are not equal hence, lines are not parallel.

We can see that -1/4 is the negative reciprocal of 4. Since.

4\cdot-\frac{1}{4}=-1

We know that the slopes of  perpendicular lines are negative reciprocal of each other.

Hence, the lines are perpendicular.

D is the correct option.

Answer:

The length of diagonal d is 14.1421 cm

Step-by-step explanation:

We are given square

Length of side of square = 10 cm

We need to find the length of diagonal d

To find diagonal of square, the formula used is:

Diagonal\: of\: square=s\sqrt{2}

where s is length of side of square.

Putting values of s and finding length of diagonal of square

Diagonal\: of\: square=s\sqrt{2}\\Diagonal\: of\: square=10\sqrt{2}\\Diagonal\: of\: square=10(1.41421)\\Diagonal\: of\: square=14.1421\:cm

So, The length of diagonal d is 14.1421 cm

Answer:

256π/3 cm³

Step-by-step explanation:

d = 2r => r = d/2 = 4cm/2 = 2 cm

V(sphere) = 4π·r³/3

= 4π·64/3 cm³

= 256π/3 cm³
