Find the distance between the two points 5,6 and 0,-6. Show your work​
valkas [14]

Answer:

The distance between two points is √169 or 13.

Step-by-step explanation:

In the question we need to find the distance between two points 5,6 and 0,-6 given.

Distance between two points can be found using the formula:

d(P1,P2) = \sqrt{(x_{2}-x_{1})^2 + (y_{2}-y_{1})^2}

Putting the given points in the formula we get,

x₂ = 0, x₁ = 5, y₂= -6, y₁= 6

=\sqrt{(0-(5))^2 + (-6-(6))^2} \\=\sqrt{(0-5)^2 + (-6-6)^2}\\=\sqrt{(-5)^2 + (-12)^2}\\=\sqrt{25 + 144}\\=\sqrt{169}\\=13

So, the distance between two points is √169 or 13.

The interest rate r required to increase your investment p to the amount a in t years is found by . Find the interest rate r for
Dahasolnce [82]

Answer:

The interest rate was of 0.1173 = 11.73%.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

A = E + P

In this problem, we have that:

A = 10000, P = 8100, t = 2

So

A = E + P

10000 = E + 8100

E = 1900

So

1900 = 8100*I*2

I = \frac{1900}{8100*2}

I = 0.1173

The interest rate was of 0.1173 = 11.73%.
