Add all the displacement vectors together, then find the magnitude of this vector sum.

$\vec r_1=(72\,\mathrm{km})(\cos60^\circ\,\vec\imath+\sin60^\circ\,\vec\jmath)$

$\vec r_2=(48\,\mathrm{km})(\cos270^\circ\,\vec\imath+\sin270^\circ\,\vec\jmath)$

$\vec r_3=(100\,\mathrm{km})(\cos150^\circ\,\vec\imath+\sin150^\circ\,vec\jmath)$

Summing these vectors gives the resultant displacement

$\vec r=\vec r_1+\vec r_2+\vec r_3\approx(-50.6\,\vec\imath+64.4\,\vec\jmath)\,\mathrm{km}$

and we have

$\|\vec r\|=\sqrt{(-50.6)^2+64.4^2}\,\mathrm{km}\approx\boxed{81.9\,\mathrm{km}}$

so the plane ends up about 81.9 km away from its starting position.

Multiply 5/8⋅4/5. Simplify the answer, if possible. 9/13 1 1/740 20/40 1/2

Fofino [41]

Answer:

1/2

The LCD is 40, so find the rest using expressions and comparisons.

8 × 5 = 40

5/8 × 4/5 = 20/40

20 ÷ 20 = 1

40 ÷ 20 = 2

Which of the following sets of numbers could represent the three sides of a right triangle

MissTica

Answer:

The pythagorean theorum states that the longest side of the right triangle (hypotenuse), squared, is equal to the sum of the squares of the 2 other sides

Its expressed as so:

$c^2=a^2+b^2$

Therefore,

{36, 48, 60} is correct
