1. What expression is same as (a. a.a)(b. b)?
A. (4a)(2b)
C. a" b2
B. a2 b2
D. 8ab​

a^3b^2

Step-by-step explanation:

Recall that the first law of indices states that

a^x * a^y = a^(x+y)

Hence the expression  (a.a.a)(b.b)

= a^(1+1+1) * b^(1+1)

= a^3b^2

This is the product of a raised to the power of 3 and b raised to the power of 2

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
