Answer:

$-\frac{13\sqrt{x} }{x}$

Step-by-step explanation:

We have been given the following expression;

-13/√x

In order to rationalize the denominator, we multiply the numerator and the denominator by √x;

$-\frac{13}{\sqrt{x}}=-\frac{13\sqrt{x} }{\sqrt{x}\sqrt{x}}\\ \\-\frac{13\sqrt{x} }{\sqrt{x^{2} } }\\\\-\frac{13\sqrt{x} }{x}$

12) A new amusement park decides to offer its visitors a choice between two plans. With Plan 1 they pay $6 to enter

astraxan [27]

Answer:

3 rides
$16.50

Step-by-step explanation:

The plan 1 cost for x rides will be ...

y = 6 + 3.50x

The plan 2 cost for x rides will be ...

y = 12 + 1.50x

These costs will be equal when ...

y = y

6 + 3.50x = 12 + 1.50x . . . . . substitute for y

2.00x = 6 . . . . . . . . . . . . . subtract 6+1.50x

x = 3 . . . . . . . . . . . . . . . divide by 2

For 3 rides, the cost will be the same.

For 3 rides the cost is ...

y = 6 + 3.50(3) = 6 + 10.50 = 16.50

The cost for 3 rides will be $16.50 for either plan.

Marcus sails due north and Sandra sails due east from the

garri49 [273]

Answer: The boats are 44.82 miles from each other.

Step-by-step explanation:

The direction of movement of Marcus and Sandra forms a right angle triangle.

The distance sailed by Marcus due North would represent the opposite side of the right angle triangle.

The distance sailed by Sandra due east would represent the adjacent side of the right angle triangle.

The distance, h between the both of them after 2 hours represents the hypotenuse of the right angle triangle.

To determine h, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

h² = 35² + 28² = 1225 + 784

h² = 2009

h = √2009

h = 44.82 miles
