Answer:
Step-by-step explanation:
From the given information:
(a)
Since growth quantity is not continuous
For t = 10
(b)
Here, for a continuous growth rate, the growth quantity can be computed in terms of initial quantity and the growth rate.
i.e.
At t = 10 for a continuous growth rate;
Home is 0.6 miles away from the store
How to solve such time related questions?
The key concept for solving such questions is the relationship between speed, distance and time.
The relationship between them is Distance = Speed x Time
Given:-
Total time taken by girl to complete the trip = 15 minutes = hours
Speed while riding going = 6 miles per hour
Speed while coming back = 4 miles per hour
Total time taken by girl =
Time taken while going + Time taken while coming back - (1)
Let x be distance from home to store
= Time taken while going
= Time taken while coming back
Substituting in (1) we get
x = 0.6 miles
Thus home is 0.6 miles away from the store

The distributive property is used to get the equivalent expression
Step-by-step explanation:
The properties on mathematical expressions are used to simplify or elaborate the expressions.
One of the propoerties is distributive properties
The distributive property states that:
Let a, b and c be three integers then
a(b+c) = ab+ac
The property can be used both ways
