Answer:
The measure of the current running through the heater is: 10 Amps
Step-by-step explanation:
Since power (which is measured in watts) is defined as the product of the voltage applied times the current that runs the device, we can use this formula to solve for the unknown current (I) in the problem. Also since the units of power given are "watts", and the voltage is given in "volts", the current will also result in SI units, that is Amperes (Amps):
Answer:
A
Step-by-step explanation:
The equation will be in the form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (2.5, 0) ← 2 points on the line
m = = - 2
The line crosses the y- axis at (0, 5) ⇒ c = 5
y = - 2x + 5 or
y = 5 - 2x → A
