Answer:

34.6574 years
34 years, 239.94 days

Step-by-step explanation:

For continuous compounding the "rule of 69" applies. That is the doubling time can be found from ...

t = 69.3147/r . . . . where r is the interest rate in percent.

Here, r=2, so ...

t = 69.3147/2 = 34.6574 . . . years

That's 34 years and 240 days.

Answer:

Step-by-step explanation:

If the area is 32 and the formula for area of a triangle is base * height / 2, and you have base = 8 and height = x and area = 32, this would be:

8 * x / 2 = 32

Now, solve:

$8x/2=32\\4x=32\\x=8$

Find the midpoint and distance between each pair of points, with easy explanation and work !! will give brainliest.

rewona [7]

If we have 2 coordinates say: (x1,y1) and (x2,y2)

Then the formula for the midpoint is:

((x1+x2)/2,(y1+y2)/2)

And the formula for the distance is:

Sqrt((x2-x1)^2+(y2-y1)^2)

So here we have (-1,-4) and (-7,4)

The midpoint is:

((-1+-7)/2,(-4+4)/2) = (-8/2,0/2) = (-4,0)

The distance is:

Sqrt((-7- -1)^2+(4- -4)^2)
= sqrt((-6^2)+(8^2))
=sqrt(36+64)
=sqrt(100)
=10
