Find the distance between each pair of points

(-3,-5) (-7,5)

√116 or 10.7703

Step-by-step explanation:

Use the distance formula, attached in the image below:

√(-7--3)²+(5--5)²

√(-4)²+(10)²

√(116)

Depending on what your teacher wants, you may solve the square root to get 10.7703, or keep it in the root form.

To solve this, we are going to use the compound interest formula: 
where
is the final amount after  years 
is the initial investment 
is the interest rate in decimal form 
is the number of times the interest is compounded per year

For the first 4 years we know that: , , , and since the problem is not specifying how often the interest is communed, we are going to assume it is compounded annually; therefore, . Lest replace those values in our formula:





Now, for the next 6 years the intial investment will be the final amount from our previous step, so . We also know that: , , and . Lets replace those values in our formula one more time:





We can conclude that Collin will have £3691.41 in his account after 10 years.
