Can someone i tried to attempt it but it wasn’t working for me

b. It depends on the value you assume for the power line voltage. If you assume it is 120 volts, then the ratio to battery voltage is

... (120 volts)/(1.2 volts) = 100

Power line voltage is 100 times as large as battery voltage.

Please be aware of some difficulties in this question.

1. Power line voltage, even if it is "120 volts" varies over time from -170 V to +170 V, so is not really comparable to a battery's voltage, which is steady at 1.2 V.

2. The terminology "times larger" is ambiguous. When we answer the question, "how much larger is a than b," we give the response in terms of the difference a-b. Thus, if a is 2 times larger than b, we might be talking about the difference being twice the value of b. It is preferable to say "times as large as."

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
