Answer:
18
Step-by-step explanation:
When dilating a segment by a scale factor, we multiply the original length by the scale factor to find the length.
2*9 = 18
1m=100cm,
so 25 m=25*100=2500cm
From this, we conclude that; Current equals Voltage divided by Resistance (I=V/R), Resistance equals Voltage divided by Current (R=V/I), and Voltage equals Current times Resistance (V=IR).To calculate voltage, V: put your finger over V, this leaves I R, so the equation is V = I × R.
To calculate current, I: put your finger over I, this leaves V over R, so the equation is I = V/R
Answer: (-3,19)
Step-by-step explanation:
Here the given function is,
Since, the standard equation of a quadratic function is 
Where (h,k) is the vertex of the function.
On comparing the equation of given function with this standard form,
We get, the vertex of the given function is (-3,19)
⇒ First option is correct.
