A car is traveling at a steady speed. It travels 2 1/2

Ksivusya [100]

Answer:

It will travel

$33 \frac{1}{4} \: miles$

in 45 minutes.

Step-by-step explanation:

We can solve using proportions.

$\frac{ 2\frac{1}{2} \: miles}{ 3\frac{1}{3} \: minutes} = \frac{x}{45 \: minutes} \\ \\ \frac{ 3\frac{1}{3} x}{ 3\frac{1}{3} } = \frac{ 112\frac{1}{2} }{ 3\frac{1}{3} } \\ \\ x = 33\frac{3}{4}$

If angle 0 is in quadrant I, what is the value of

Brilliant_brown [7]

Answer:

$the \: answer \: is \: c \: = - \frac{ \sqrt{14} }{5}$

Step-by-step explanation:

$\sin^{2}0 + ( \frac{ \sqrt{11} }{5} ) ^{2} = 1( \sin^{2}0 + \cos^{2} 0 = 1)$

${ \sin }^{2}0 + \frac{11}{25} = 1 \\ { \sin }^{2}0 = \frac{14}{25}$

$\sin0_{1} = - \frac{ \sqrt{14}}{5} while \sin0_{2} = \frac{ \sqrt{14} }{5}$

Therfore theta is QI
Therfore sin theta >0
$therefore \: \sin0 = \frac{ \sqrt{14} }{5}$
