The number of people using an older version of a spreadsheet program decreases at a rate that is proportional at any time to the

Paraphin [41]

Answer:

5842 people after 2 months

Step-by-step explanation:

Given

Initial Value: $a =10000$

Rate: $r = 20\%$ every 6 months

Required

Number of people using it after 2 months

The function follows an exponential model.

So, we need to first write out the function.

If Rate: $r = 20\%$ every 6 months

Then

Rate: $r = 40\%$ after 1 year

$r = 0.04$

The function is represented as:

$y = ar^x$

So:

$y = 10000 * 0.04^t$

For 2 months, we have:

$t = 2\ months$

Convert to years

$t = \frac{2}{12}$

$t = 0.167$

$y = 10000 * 0.04^t$

$y = 10000 * 0.04^{0.167}$

$y = 5842$

Phantasy [73]

Answer:

Step-by-step explanation:

$2\sqrt{3} sin^{2} \alpha -cos\alpha =0\\2\sqrt{3} (1-cos ^2 \alpha )-cos \alpha =0\\2\sqrt{3} -2\sqrt{3} cos^2 \alpha -cos \alpha =0\\2\sqrt{3} cos^2 \alpha +cos \alpha -2\sqrt{3} =0\\cos \alpha =\frac{-1 \pm\sqrt{1^2-4*2\sqrt{3}*(-2\sqrt{3}) } }{2*2\sqrt{3} } \\=\frac{-1 \pm\sqrt{1+48} }{4\sqrt{3} } \\=\frac{-1\pm7}{4\sqrt{3} } \\either~cos \alpha =\frac{6}{4\sqrt{3} }=\frac{\sqrt{3} }{2} \\=cos \frac{\pi }{6} ,cos(2\pi -\frac{\pi }{6} )\\=cos \frac{\pi}{6} ,cos \frac{11\pi }{6}$

$\alpha =2 n\pi+ \frac{\pi }{6} ,2n\pi +\frac{11\pi }{6} (general~solution)$

$or~cos\alpha =-\frac{7}{4\sqrt{3} } \\ \alpha =cos^{-1}( \frac{-7}{4\sqrt{3} } )$

Solve for y. 7y - 6y - 10 = 13

salantis [7]

Start off by combining like terms (your y's).
7y - 6y - 10 = 13
y - 10 = 13

Now you need to get y by itself so add 10 to both sides

y - 10 = 13
+10 +10

y = 23
