George plays basketball in a week long camp On day 2 he scored 8 points On day 4 he scored 12 points Explain how to measure his
Kay [80]
To measure George's rate of change, we first set out two pairs of independent and dependent data which in this case is the day number and the point

Independent Data: Day 2                          Independent Data: Day 4
Dependent Data: 8 points                         Dependant Data: 12 points

Then we find the difference between the two independent values and the two dependent values

4 - 2 = 2
12 - 8 =4

To find the rate we use the following formula 
the difference of dependent value ÷ the difference of independent value =
4 ÷ 2 = 2

Hence the average rate of change is an increase of 2 points a day

Maple town is 16 kilometers due north of the airport and sachet town is due east of the airport. The shortest distance between m
Alexxandr [17]

Answer:

Sachet town is 12km from the airport

Step-by-step explanation:

In this question, we are asked to calculate the distance from sachet town to the airport.

This can be calculated by referring to a diagrammatic representation. Please check attached file.

Let’s proceed with the calculations however.

From the question, we can see that we have formed a Right angled triangle from the diagram and we need to calculate the distance x.

Mathematically;

x^2 + 16^2 = 20^2

x^2 = 20^2 - 16^2

x^2 = 400 - 256

x^2 = 144

x = sq.rt of 144

x = 12km
