So at the end of the third year, it would be 800 x^3 + 600x^2? And he doesn't work the third summer? Then 800x^3 + 600x^2 = 1650 x = 1.0657758228... so he needs an interest rate of 6.57758.... % compounded annually.

Dave was playing checkers with a friend. The ratio of games Dave won was 7:2. If Dave won 35 games, how many games did his frien

Mars2501 [29]

Answer:

His friend won 10 games.

Step-by-step explanation:

In order to find this, divide the number of games that he won by his part of the proportion (7).

35/7 = 5

5 in this case is the scale factor. We can now multiply his friend's winnings to get the total number of his wins.

5 * 2 = 10

Over what interval is the function differentiable? Y=3/2(x-1)

jolli1 [7]

Answer-

The interval where the function is diffrentiable is

$[-\infty,1)\ \bigcup\ (1,\infty]$

Solution-

The given expression is,

$y=\dfrac{3}{2(x-1)}$

The function will be differentiable where it is continuous and it will not be differentiable, where the function is not continuous.

The function continuous everywhere except at x = 1, because

$\Rightarrow 2(x-1)=0\\\\\Rightarrow x-1=0\\\\\Rightarrow x=1$

at x = 1, its limit does not exist.

Therefore, apart from x=1, this function is differentiable everywhere. The interval will be

$[-\infty,1)\ \bigcup\ (1,\infty]$
