Answer:

w = 9.82

x = 66.73

Step-by-step explanation:

By applying tangent rule in triangle ABD,

tan(81°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

6.31 = $\frac{62}{w}$

w = $\frac{62}{6.31}$

w = 9.82

Similarly,

tan(39°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

0.81 = $\frac{62}{(x+w)}$

0.81 = $\frac{62}{9.83+x}$

9.82 + x = $\frac{62}{0.81}$

x = 76.56 - 9.82

x = 66.74

One root of the quadratic equation x^2 − 2x + m = 0 is 9. If the other root is n, what is n−m?

mote1985 [20]

$9^2-2*9+m=0\\
\\
81-18+m=0\\
\\
m=-63$

$x^{2} -2x-63=0\\
\\
\Delta=(-2)^2-4.1.(-63)=4+252=256\\
\\
x=\frac{2 \pm 16}{2}\\
\\
x_1=\frac{18}{2}=9\\
\\
n=x_2=\frac{-14}{2}=-7\\
\\
n-n=-7-(-63)=-7+63=56$

A plane can fly 290 miles downwind in the same amount of time as it can travel 220 miles upwind. Find the velocity of the wind i

nikitadnepr [17]

Answer:

The speed of the wind is $35\ mph$

Step-by-step explanation:

Let

x-----> the speed of the wind in mph

we know that

Downwind

$(255+x)=\frac{290}{t}$

$t=\frac{290}{(255+x)}$ -----> equation A

Upwind

$(255-x)=\frac{220}{t}$

$t=\frac{220}{(255-x)}$ ----> equation B

equate the equation A and the equation B

$\frac{290}{(255+x)}=\frac{220}{(255-x)}\\ \\290(255-x)=220(255+x)\\ \\ 73,950-290x= 56,100x+220x\\ \\220x+290x=73,950-56,100\\ \\510x=17,850\\ \\x= 35\ mph$
