answer:

f (2) = 6

step-by-step explanation:

  • first plug in 2 as x
  • f(2) basically means x = 2

f (2) = 3(2)^0 - 2(2)^-1 + 4

  • solve the exponents and use PEMDAS

f (2) = 3(2)^0 - 2(2)^-1 + 4

f (2) = 3 - 1 + 4

  • 2 to the 0th power is 1
  • 3 times 1 is 3 so we get 3
  • 2 to the power of -1 is 1/2 (it gets flipped)
  • -2 times 1/2 is -1 so we get 1
  • there is nothing to do with +4 so we bring it down
  • now, simply solve it using PEMDAS

f (2) = 3 - 1 + 4

f (2) = 2 + 4

f (2) = 6

Below are the rates of travel of 4 shipping trucks. Which truck drove the fastest rate? Truck A: 300 miles in 4 hours Truck B: 2
Tasya [4]

Answer:

Truck D.

Step-by-step explanation:

Below are the rates of travel of 4 shipping trucks.

Truck A: 300 miles in 4 hours Truck B: 240 miles in 3 hours Truck C: 325 miles in 5 hours Truck D: 170 miles in 2 hours.

Speed = distance/time

Speed of Truck A,

v_A=\dfrac{300}{4}\\\\v_A=75\ mph

Speed of Truck B,

v_B=\dfrac{240}{3}\\\\v_B=80\ mph

Speed of Truck C,

v_C=\dfrac{325}{5}\\\\v_C=65\ mph

Speed of Truck D,

v_D=\dfrac{170}{2}\\\\v_D=85\ mph

It can be seen that the speed of Truck D is more out of Trucks A,B and C. Hence, Truck D is moving at a faster rate.
