If a is a negative number, then a(1/a) is equal to -1. If a is a negative number and b is a negative number, then product ab is
Firdavs [7]

Both claims are false. In fact, a and \frac{1}{a} are one the multiplicative inverse of the other. This means, by definition of multiplicative inverse, that

a \cdot \dfrac{1}{a} = 1 \quad\forall a \in \mathbb{R}

So, it doesn't matter if a is positive or negative: the multiplication of one number and its inverse will always be 1: for example,

(-2) \cdot \dfrac{1}{-2} = \dfrac{-2}{-2} = 1

Similarly, when you multiply two number, the sign of the product depends on the sign of the factors as follows:

  • (+) \cdot (+) = (+)
  • (+) \cdot (-) = (-)
  • (-) \cdot (+) = (-)
  • (-) \cdot (-) = (+)

So, the multiplication of two negative numbers is a positive number.

A particle travels along the x-axis such that its position at time t is given by the function x(t)= 2t^2+t. What is the average
Lapatulllka [165]

Answer:

4: A

Step-by-step explanation:

Mathematically, the average speed over a particular range will be;

f’(b)-f’(a)/(a-b)

In this case; a = 2 and b = 10

So we have the following;

f’(x) = 4t + 1

f’(10) = 4(10) + 1 = 41

f’(2) = 4(2) + 1 = 9

So we have the average speed change as;

(41-9)/(10-2)

= 32/8 = 4
