If f(x) = 2 (3x) + 1 , what is the value of f(2) ?

13

Step-by-step explanation:

f(x)=2(3x)+1

f(2)=2(3X2)+1

f(2)=2(6)+1

f(2)=12+1

f(2)=13

13.

Step-by-step explanation:

Replace the x in f(x) by 2 and work it out:

f(2) = 2(3*2) + 1

= 2(6) + 1

= 13.

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

x = 3 ± √(5+y)
