Luda [366]

Answer:

<h3>The answer is 10132.5 g</h3>

Step-by-step explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of silver = 965 cm³

density = 10.5 g/cm³

The mass of silver is

mass = 965 × 10.5

We have the final answer as

<h3>10132.5 g</h3>

Flura [38]

Answer:

The answer to your question is:

Step-by-step explanation:

If the line is rotated, we get the perpendicular of the initial line.

See the attachment, the blue line is the original and the red one is the new line.

Process

new slope = 2/5

Point ( 0, 4)

                 (y - y1) = m (x - x1)

                 ( y - 4) = 2/5 (x - 0)

                 y - 4 = 2/5 x

                y = 2/5 x + 4             New line
