Answer:

I think its D

Step-by-step explanation:

I said this because 410/8 equals 51.25 and if you multiply that by x (8) you will get 410. Hopefully i got this correct.

<h3>Answer:  1679</h3>

=========================================================

Explanation:

The notation 47^{\circ}4' means "47 degrees, 4 minutes". The "minutes" isn't referring to a time value, but instead they are arc minutes. If we divide one degree into 60 equal pieces, then we form 60 arc minute slices. So in a sense, we are using a round analogue clock to help connect the two ideas.

We can convert to purely degrees through using this formula here

a^{\circ}b' = a + \frac{b}{60}

So,

47^{\circ}4' = 47 + \frac{4}{60} \approx 47.06667^{\circ}

and similarly,

22^{\circ}46' = 22+ \frac{46}{60} \approx 22.76667^{\circ}

Now subtract the two results we got

47.06667-22.76667 = 24.3

The angular distance between the two cities is 24.3 degrees. By "angular distance" I basically mean how far you need to rotate your viewing angle when looking from city A to city B. Imagine that you're able to be situated at the center of the earth.

The circumference of the earth is

C = 2*pi*r

C = 2*pi*3960

C = 24,881.4138164311

which is approximate and the units are in miles. We multiply by the fraction 24.3/360 to find the arc distance along the curve that corresponds to the angle 24.3 degrees. This is because we don't want the whole circumference, but just a small fraction of it.

So (24.3/360)*24,881.4138164311 = 1,679.4954326091

This rounds to 1679

The distance between the two cities is about 1679 miles.

Find a set of parametric equations for the line of intersection of the planes x-3y+6z=4 5x+y-z=4
Inessa05 [86]

Answer:

Step-by-step explanation:

Two equations of planes are given.

We have to find the equation of the line which is formed by intersection of these two planes in parametric form

x-3y+6z=4 \\5x+y-z=4

Let us eliminate one variable

Multiply I equation by 5 and subtract II from 5 * I

5x-15y+30z=20 \\5x+y-z=4

-16y+31z=16 \\

16y+16 = 31z

Or y+1 =\frac{31z}{16}

Consider II equation

5x+y-z=4

5x+\frac{31z}{16}-1 -z=4\\5x+\frac{15z}{16}=5\\x=\frac{3z-16}{16}

Let z=z

x = \frac{3z-16}{16} and y = \frac{31z}{16}-1
