Answer:
Option (2)
Step-by-step explanation:
Parent function has been given as,
f(x) = 
When translated by 3 units left,
f(x + 3) = 
g(x) =
If the translated function is stretched vertically by a scale factor = k
New function will be,
g'(x) = 
Since a point (1, 4) passes lies on the transformed function.
g'(1) = 
4 = 2k
k = 2
Therefore, transformed function represents the translation by 3 units in the negative side of the x-axis and stretched vertically by 2 units.
Option (2) will be the answer.
Answer:
I think it may be C? I used desmos to graph it but I'm not 100%
Answer:
12565.11 teeth approximately cut cross the cutting surface per seconds.
Step-by-step explanation:
Since the diameter is 10inches, the circumference of the arm saw is 10π (circumference is πd where d is diameter).
The number of teeth on the cutting blade can be gotten by multiplying the diameter by 12 since we have 12 teeth per inch on the arm saw
Number of teeth on saw = 12 x 10π = 120π.
To get the number of teeth that cross the cutting surface in 2000rpm we multiple it by the total number of teeth in just one rpm.
So we have 2000 x 120π. But since we are asked to find it in revolution per seconds then 2000r/m = 2000r/60s ≈ 33.33
Therefore, we have
33.33 x 120π ≈ 12565.11 teeth
