Answer:
In order to understand exponential equations with a whole number and a fraction, we have to revisit the definition.
Exponentiation is just repeated multiplication. For instance, if we have 2^3, we can see that 2 * 2 * 2 = 8. The number keeps getting bigger.
Likewise, if we have (1/2)^3, 1/2 * 1/2 * 1/2 = 1/8. The number keeps getting smaller. Notice a pattern?
When we have a number greater than 1 as a base in an exponential function, the number keeps growing. This is called exponential growth.
In contrast, whenever we have a number less than 1 as a base (i.e. a fraction), the number keeps getting smaller. This is called exponential decay.
Hope this helps.
Answer:
The assumption to prove that vertical angles are congruent is "Vertical angles are always congruent".
Step-by-step explanation:
Vertical angles are a pair of angles (not adjacent) opposite each other by a vertex when two lines intersect.
When two lines intercept at a point, 4 angles are formed. Those that are opposite to each other and are not adjacent are vertical angles, these are always congruent.
In this case, we can affirm that if two angles are opposed by the vertex, they are equal.
Have a nice day!
