Answer:
C) 80 milliamperes
Step-by-step explanation:
The amount of current flowing through a circuit is directly proportional to the amount of voltage applied across the circuit. The relation between current(I) and voltage(V) can be expressed as:
Here, 
is the proportionality constant. It is given that, when voltage is 2 volts, 40 milliamperes(
amperes) current flow through the circuit. Using these values we can find the value of proportionality constant. i.e.
Using this value, we can establish the relation between I and V as:
Now, we need to calculate value current (I) if voltage is equal to 4 volts. Substituting V = 4 in above equation, we get:
Thus, the value of current will be 80 milliamperes
" Rachel must pay a $20 membership fee to join the gym " can be interpreted from the y-intercept of the function ⇒ D
Step-by-step explanation:
The form of the linear function is f(x) = mx + b, where
- m is the slope (rate of change) of the function
- b is the y-intercept (initial amount) of the function
∵ f(x) = 37 x + 20 models the total cost for Rachel to be a member
at a gym for x months
∵ f(x) = m x + b
∴ m = 37 and b = 20
∵ m represents the rate of change
- That means she must to pay 37 per month for x months
∴ Rachel must pay $37 per month to use the gym
∵ b represents the initial amount
- That means she pays a fixed amount one time
∴ Rachel must pay a $20 membership fee to join the gym
" Rachel must pay a $20 membership fee to join the gym " can be interpreted from the y-intercept of the function
