You're flying from Joint Base Lewis-McChord (JBLM) to an undisclosed location 201 km south and 194 km east. Mt. Rainier is locat

elixir [45]

Answer:

The answer is "0.0846276476".

Step-by-step explanation:

Let all the origin(0,0) of JBLM be

Let the y-axis be north along with the vector j unit.

But along the + ve x-axis is east, and all along with the vector unit i.

And at (194,-201) that undisclosed position is

Mt. Ris (56,-40) at

Let the moment it gets close to the Mt. rainier bet.

Oh, then,

If we know, the parallel to the direction from the point was its nearest one to a path to a point,

Calculating slope:

$\to m=\frac{y_2-y_1}{x_2-x_1}\\$

points: (0,0) and (194,-201)

$\to m=\frac{-201 -0 }{194-0}\\\\\to m=\frac{-201}{194}\\\\\to m=-1.03$

equation of the line:

$\to y= mx+c\\\\\to y= -1.03\ x+c$

when the slope is perpendicular= $-\frac{1}{m}$

$= - \frac{1}{ -1.03}\\\\= \frac{1}{ 1.03}\\\\= 0.97$

perpendicular equation:

$\to y-(-40)=0.97 \times (x-56) \\\\\to y+40=0.97 \times (x-56) \\\\$

Going to solve both of the equations to have the intersection point,

We get to the intersect level in order to be at

(47.16,-48.5748)

so the distance from origin:

$= \sqrt{(47.16^2+48.5748^2)}\\\\= \sqrt{2224.0656 + 2359.5112}\\\\=\sqrt{4583.5768}\\\\=67.7021181$

$\to time =\frac{distance }{speed}$

$= \frac{67.7021181}{800}\\\\= 0.0846276476$

Can someone please answer this question please answer it correctly

Studentka2010 [4]

Answer:

Step-by-step explanation:

so any values inside the absolute value brackets | | will become positive even if they are negative, this is because absolute value represents distance from a number to 0 on a number line and you can't have a negative distance.

|-9|=9

and

|9|=9

hope this helps!

Using coupons, you spend $135 grocery shopping. this is 75% of the total retail price of the groceries. how much would you have

Usimov [2.4K]

Let x be the total price. And you paid 75% of it which is $135.

x * 75/100 = 135
x = 180
You would have paid $180 if you had not used coupons.
