An above ground swimming pool is leaking after 1 and 1/2 hours the pool has leaked 7/8 of a gallon of water how many gallons of

Aleksandr [31]

Answer:

In 1 hour the amount of water leaking from pool = $\frac{7}{12}$ gallon of water

Step-by-step explanation:

Given as :

The amount of Leaking of water from the pool = $\frac{7}{8}$ gallon

The time taken fro leaking $\frac{7}{8}$ gallon of water = 1 $\frac{1}{2}$ gallon hour

Or The time taken fro leaking $\frac{7}{8}$ gallon of water = $\frac{3}{2}$ hour

∵ $\frac{3}{2}$ hour takes for leaking $\frac{7}{8}$ gallon of water

∴ In 1 hour the amount of water leaking from pool = $\frac{7}{8}\setminus \frac{3}{2}$

Or, In 1 hour the amount of water leaking from pool = $\frac{7}{12}$ gallon of water Answer

Which portion of the unit circle satisfies the trigonometric inequality cos^2theta + sin^2theta is greater than or equal to 1. A

liberstina [14]

Answer:

Only points on the circle satisfy the given inequality.

Step-by-step explanation:

Given: Unit circle

To find: portion of the unit circle which satisfies the trigonometric inequality $\sin ^2\theta +\cos ^2\theta \geq 1$

Solution:

In the given figure, OA = 1 unit (as radius of the unit circle equal to 1)

$\sin \theta$ = side opposite to $\theta$ /hypotenuse

$\cos \theta$ = side adjacent to $\theta$ /hypotenuse

$\sin \theta =\frac{AB}{AO}\\\sin \theta =\frac{AB}{1}\\AB=\sin \theta$

$\cos \theta=\frac{OB}{AO}\\\cos \theta =\frac{OB}{1}\\OB=\cos \theta$

So, coordinates of A = $\left ( \cos \theta ,\sin \theta \right )$

For any point (x,y) on the unit circle with centre at origin, equation of circle is given by $x^2+y^2=1$

Put $(x,y)=\left ( \cos \theta ,\sin \theta \right )$

$\cos ^2\theta +\sin ^2\theta =1$

So, $(x,y)=\left ( \cos \theta ,\sin \theta \right )$ satisfies the equation $x^2+y^2=1$

For points $(x,y)=\left ( \cos \theta ,\sin \theta \right )$ inside the circle, $\cos ^2\theta +\sin ^2\theta$

For points $(x,y)=\left ( \cos \theta ,\sin \theta \right )$ outside the circle, $\cos ^2\theta +\sin ^2\theta >1$

So, only points on the circle satisfy the given inequality.
