Well earth's circumference is 24,860 miles 

if you walked 24,860 miles at 5 miles per hour it would take you 4,972 hours

4,972 divided by 24 = 207.17

it would take you 207.17 days

The earth equator has circumference of 24901.55 miles !!

so time = distance/ time
= 24901.55 / 5
= 4980.31 hours

so in days, ( divide by 24 ) ,
so, 4980.31/24
=207.5 days !!

so it will take 207.5 days to walk around equator !!

Let v1=(2,-6) and v2=(-4,7)
seropon [69]

The magnitude of each vector is the Pythagorean sum of its components.


a. |v1| = √(2² + (-6)²) = √40 = 2√10

|v2| = √((-4)² + 7²) = √65


b. To make each vector into a unit vector, divide each component by the vector's magnitude.

u1 = v1/|v1| = (2/(2√10), -6/(2√10))

u1 = (√10/10, -3√10/10)


u2 = v2/|v2| = (-4/√65, 7/√65)

u2 = (-4√65/65, 7√65/65)

The function f(x) is given by the set of ordered pairs.
Lana71 [14]

The equation that is true and one that matches the set of ordered pairs of functions is option C. f (0) = 6

<h3>What is the equation about?</h3>

Note that a function can be made to be a given set of ordered pairs such as the ordered pairs (2,4), (3,5), (4,6)  can have  input functions of ​​(as domain) 2,3,4 and output functions of ​​(as range) of 4,5,6.

So when you see the ordered pairs. {(1,0), (–10,2), (0,6), (3,17), (–2, –1)} one can see that the option that matches to the set of ordered pairs of functions above is f (0) = 6 value x = 0, f (x) = y = 6, ordered pairs (0.6)

See full question below

The function f (x) is given by the set of ordered pairs. {(1,0), (–10,2), (0,6), (3,17), (–2, –1)}:Which equation is true?

f(-10)=1

f(2)=-10

f(0)=6

f(1)=-10

The answer choices are :

f (-10) = 1 values ​​x = -10, f (x) = y = 1, ordered pairs (-10,1)

f (2) = - 10 values ​​x = 2, f (x) = y = -10, ordered pairs (2, -10)

f (0) = 6 value x = 0, f (x) = y = 6, ordered pairs (0.6)

f (1) = - 10 values ​​x = 1, f (x) = y = -10, ordered pairs (1, -10)

Write the measure 29° 6' 6" as decimal to the nearest thousandth.
den301095 [7]
This angle is "29 degrees 6 minutes 6 seconds".

-- There are 60 minutes in 1 degree. 
     So 1 minute = 1/60 degree.

-- There are 60 seconds in 1 minute. 
      So 1 second = 1/60 minute = 1/3600 degree.

  29  6'  6"  =  (29)° + (6/60)° + (6/3600)°

                   =  (29)° + (0.1)° + (0.001666...)°

                   =        29.101666...°

Rounded to the nearest thousandth of a degree:  29.102°
