From an elevation of 0.5 m below the surface of the water, a swimmer dives at a rate of 0.25 m/s. What is the function rule for the swimmer's depth, d, and time, t?

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

current in the circuit at time t is /, then the power delivered to the resistor is
