An airplane flying at 600 miles per hour has a bearing of 53°. After flying for 2.5 hours, how far north and how far east will t

serg [7]

Answer:

Eastward distance of airplane = 903 miles

Northward distance of airplane = 1198 miles

Step-by-step explanation:

Consider the sketch attached below.

Let the Eastward distance be represented by x

let the Northward distance be represerted by y

The distance traveled = speed of plane x time

= 600 x 2.5 = 1500 miles

from basic trigonometry of a right angled triangle we have that

$sin(53)=\frac{x}{1500}$

$x=1500\timessin(53) \approx 903 miles$

$cos (53) = \frac{y}{1500}$

$y= 1500cos(53)\approx1198 miles$

∴ Northward distance = 1198 miles

Eastward distance =903 miles

Solve this system of equations using the addition method.<br> 5x + 2y = 19<br> x - 2y = -1

Elena-2011 [213]

2y+5x-5x= 19-5x. x-x-2y=-1-x
2y= 19-5x. -2y=-1-x
÷2= ÷2. ÷-2 = ÷-2
y= 19/2 -5/2x. Y = 1/2 + x/2

how to transform the quantity of the fifth root of x to the seventh power, to the third power into an expression with a rational

Maurinko [17]

$\bf a^{\frac{{ n}}{{ m}}} \implies \sqrt[{ m}]{a^{ n}} \qquad \qquad
\sqrt[{ m}]{a^{ n}}\implies a^{\frac{{ n}}{{ m}}}\\\\
-----------------------------\\\\
\sqrt[5]{(x^7)^3}\implies \sqrt[5]{x^{7\cdot 3}}\implies \sqrt[5]{x^{21}}\implies x^{\cfrac{}{}\frac{21}{5}}$
