The relationship between space, time and velocity for a uniform motion is given by:
S=vt
where
S is the distance covered
t is the time
v is the velocity

The plane in our problem has a velocity of
v=170 m/h
and so during a total time of t=4 h, the distance it covers is
S=vt=(170 m/h)(4 h)=680 mi
therefore, 680 miles.

Find the coterminal angle between 0 and 360°of the angle -280°
Bond [772]

Answer: So, the coterminal angle of 450° is -90°.

Step-by-step explanation:(i) 395°  

Write 395° in terms of 360°.

395°  =  360° + 35°

So, the coterminal angle of 395° is 35◦

(ii) 525°

Write 525° in terms of 360°.

525°  =  360° + 165°  

So, the coterminal angle of 525° is 165°.

(iii) 1150°

Write 1150° in terms of 360°.

1150°  =  3(360°) + 70°  

So, the coterminal angle of 1150° is 70°.

(iv) -270°

Write -270° in terms of 360°.

-270°  =  -360° + 90°

So, the coterminal angle of 270° is 90°.

(v) -450°

Write -450° in terms of 360°.

-450°  =  -360° - 90°  

So, the coterminal angle of 450° is -90°.

A powered by B equals B powered by A. A does not equal B. What's A and what's B?
MrRissso [65]

Answer:

Step-by-step explanation:

I know that there is a zero and a 1 involved in this somewhere. The  only answer I can get which is a bit of a cheat, is

1^0! = 0!^1

These are not exactly the same thing. The trouble is that they are equal. There is a difference between "not the same thing" and "equal."

If I think of something else, I'll put it in a comment.

Which of the following is the equation of a circle with a radius of 10 cm and center at (–3, 6)?
Volgvan

The equation of the circle:

(x-h)^2+(y-k)^2=r^2

(h, k) - center

r - radius

We have:

r=10\\(-3,\ 6)\to h=-3,\ k=6

Substitute:

(x-(-3))^2+(y-6)^2=10^2\\\\(x+3)^2+(y-6)^2=100
