Sin^(1/2) x cos x - sin^(5/2) cos x
= sin^(1/2) x cos x - sin(1/2)x sin^2 x cos x
factoring we get:
cos x sin^(1/2) x ( 1 - sin^2 x)
Now 1 - sin^2 x = cos^2 x so we have

cos x sin^(1/2) x * cos^2 x

= cos^3 x sqrt sin x

Martha bought 3 apples and 6 oranges She had $10 in her wallet which was enough money for the purchase wrie a asystem of equatio

meriva

3x + 6y = 10 is the equation to determine of an apple x and the price of an orange y

Solution:

Let the price of each apple = $ x

Let the price of each orange = $ y

Martha bought 3 apples and 6 oranges

She had $10 in her wallet which was enough money for the purchase

Thus the equation is:

Total amount = 3 apples(price of each apple) + 6 oranges(price of each orange)

Thus we get,

$10 = 3x + 6y\\\\3x + 6y = 10$

Thus the equation is found
