Answer:

103.65 mph

Step-by-step explanation:

A bearing of 250 deg is 200 deg on the coordinate plane.

Find the x- and y-components of the speed vectors. Add them. Then find the magnitude of the resultant.

Hx = 110 cos 200° = -103.366

Hy = 110 sin 200° = -37.622

Ax = 0

Ay = 30

Hx + Ax = -103.366

Hy + Ay = -37.622 + 30 = -7.622

sqrt(-103.366^2 + -7.622^2) = 103.65

Answer: 103.65 mph

HELP ASAP PLZ &THANK YOU :)

The standard form:

$Ax+By=C$

The slope-intercept form:

$y=mx+b$

m - slope

$m=\dfrac{y_2-y_1}{x_2-x_1}$

b - y-intercept (0, b).

We have the point (0, 43) → b= 43.

Next point (2, 55). Substitute to the slope formula:

$m=\dfrac{55-43}{2-0}=\dfrac{12}{2}=6$

Therefore we have:

$y=6x+43$ <em>subtract 6x from both sides</em>

$\boxed{-6x+y=43}$

The midpoint M and one endpoint of JK are given. Find the coordinates of the other endpoint. J(7,2) and M(1,-2)

djverab [1.8K]

Step-by-step explanation:

Xj + Xk/2 = Xm

7 + Xk/2 = 1

to get rid of the bracket, multiply all two sides by the denominator.

2(7 + Xk/2) = 1(2)

7 + Xk = 2

Xk = 2 - 7

Xk = -5

Yj + Yk/2 = Ym

2 + Yk/2 = -2

to get rid of the bracket, multiply all two sides by the denominator.

2(2 + Yk/2) = -2(2)

2 + Yk = -4

Yk = -4 - 2

Yk = -6

Therefore the coordinates of point K is (-5,-6)
