$\large \underline{ \mathbb{QUESTION:}}$

Find the exact value of csc² 30° + cos² 45°.

$\large \underline{ \mathbb{SOLUTION:}}$

$\tt{csc^{2} \: 30^{o} \: + \: cos^{2} \: 45^{o} \: = \: 2^{2} \: + \: ( \frac{1}{ \sqrt{2} }^{2}) }$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \tt{ = \: 4 \: + \: \frac{1}{2} }$

$\:\:\:\:\:\:\:\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{\tt{ \red{ = \: 4 \frac{1}{2} }}}$

Therefore the exact value of csc² 30° + cos² 45° is $\tt\red{4 \frac{1}{2} }$

grandymaker [24]

Answer:

Because the per mile charge is $2.65 per mile .. so for x miles, the per mile charge is 2.65x. And the fixed charge is the initial charge of $2.50.

y = 2.50 + 2.65x

Two airplanes are are 1600 miles apart and heading toward each other at different altitudes. The first plane is traveling north

Elden [556K]

The planes will pass each other in 1.14 hours.

Why?

To solve the problem, we must remember that since both planes are heading toward each other, the speed to the calculations will be their combined speeds.

The speed will be:

$Speed=PlaneA+PlaneB\\\\Speed=620mph+780mph=1400mph$

Now, calculating the time, we have:

$x=v*t\\\\1600mi=1400mph*t\\\\t=\frac{1600mi}{1400mph}=1.14hours$

Hence, the planes will pass each other in 1.14 hours.

Have a nice day!
