Which of the following statements is FALSE? A. If a function has a common 1st difference, it is linear.

B. If a function has a common 2nd difference it is quadratic.

C. The highest exponent of a quadratic function is 3

D. f(x) = (x + 4)(x - 5) is written in Intercept Form​

A. is the answer

Step-by-step explanation:

If the first difference is the same value, the model will be linear.

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
