Answer: R = 34

Step-by-step explanation: In physics this is Ohm's Law, where voltage = current x resistance. Thus, an electrical circuit would be V = 17 x 10, or V = 170 volts. Now, in a real circuit, if the voltage remains constant and the current changes, the resistance will change proportionally. In this case it would be 170 = R x 5, or R = 170/5 = 34 ohms. In the same way, adding resistance to a circuit with a fixed voltage reduces the current through the circuit.

In the case of a simple stated inverse proportional relationship we can simply write the current ratio as 17/5. Then the corresponding changed resistance ratio would be 10/R. The INVERSE is R/10 so the equation is 17/5 = R/10 ; R = 10(17/5) ; R = 170/5

use the graph to determine the domain and range of the relation and state whether the relation is a function
Alex

Answer:

the domain is {0, 1, 2, 3, 4... to positive infinity}

The range is {-1, -3, 0, -4 and so on}

this is not a function

Step-by-step explanation:

domain is a set of all x values, so just write the x values based on the graph

range is a set of all y values, so just write y values based on the graph

not function because it doesnt satisfy with the vertical line test.
