Step-by-step explanation:
The question is on graphing linear functions
Given the table of values of x and y, plot the graph and observe the gradient of -2 and the y-intercept at (0,-5) as shown on the attached graph with blue color.
Use the given function y=7x+13 to formulate a table of values of x with corresponding values of y
x y
-3 -8
0 13
1 20
With the above values, plot the graph of y=7x+13 and obtain the y-intercept at (0,13) as shown in the red line graph attached.
To find the distance between the y-intercepts of the two graphs we apply the expression for distance between two points;
[/tex]
points are (0,-5) and (0,13)
D=√ (0-0)² + (13--5)²
D=√(18)²
D=18 units
Answer: SERIES = 670 Ω
PARALLEL = 91.94 Ω
Step-by-step explanation:
Hi, resistors in series obey the following equation :
R1+ R2 = RT
RT is the equivalent resistance. We have the value of both resistances, so we apply the ecuation:
R1 = 110Ω, and R2 = 560Ω
110Ω+ 560Ω = 670 Ω
When resistors are in parallel, resistors obey the following equation:
1/R1 + 1/R2= 1/RT
so, in our case:
1/ 110Ω +1/560Ω = 1/rt
0.01087Ω = 1/RT
RT= 1/0.01087 Ω= 91.94 Ω
