Answer:
d
Step-by-step explanation:
it goes with the correct statements in the sentences it is the right symbol and has the variable for the unknown amount of devices
The given equation is a wave function. When plotted, the graph is shown in the attached picture. However, the unit is in degrees instead of radians. A unit of π is equivalent to 180°. This plot could determine one variable if the other is given.
273.8cm of wood framing
934mm=93.4cm
2(43.5+93.4)=y
2(136.9)=y
273.8=y
Actually, d here represents distance and r 1 and r2 are different rates of travelling d/r gives the time and we know, distance upon time is Rate .
