1 answer:

5 0

Answer:

"The specific heat capacity, c, is the heat energy that is needed to raise the temperature of a specific mass of the substance, namely 1 kg, through 1 degree celsius. Specific heat capacity is measured in joules per kilogram degree celsius (J/kg °C)."

4=k/d^2 and 1=k/64 so if we divide the first by the second we get:

4/1=(k/d^2)/(k/64)

4=(k/d^2)*(64/k)

4=64/d^2

d^2=64/4

d^2=16

d=4 meters

Solve each system by graphing.

Answer:

(x, y) = (4, -4)

Step-by-step explanation:

A graphing calculator makes graphing very easy. The attachment shows the solution to be (x, y) = (4, -4).

The equations are in slope-intercept form, so it is convenient to start from the y-intercept and use the slope (rise/run) to find additional points on the line.

The first line can be drawn by staring at (0, -2) and moving down 1 grid unit for each 2 to the right.

The second line can be drawn by starting at (0, 2) and moving down 3 grid units for each 2 to the right.

The point of intersection of the lines, (4, -4), is the solution to the system of equations.
