Answer:

The range is all the y values.

Therefore, the range is : {-4,-2,2}.....I realize choice c has all the y values listed, however, if u have repeating y values, u only have to list it once.

Shelly and her family are riding the Pikes Peak Cog Railway. The table shows the approximate distances the train has covered at
Radda [10]

Answer:

The equation that can be used to find the distance (d), the train will travel in any number of minutes (m) is d=0.12m

Step-by-step explanation:

we know that

distance  = \frac{speed}{time}

From the table below

CASE 1:

When time is 5 minutes and  distance is 0.6 miles

Speed = \frac{Distance}{time}

Speed =\frac{0.6}{5}

speed  = 0.12

CASE 2:

When time is 8 minutes and  distance is 0.96 miles

Speed = \frac{Distance}{time}

Speed =\frac{0.96}{8}

speed  = 0.12

CASE 3:

When time is 11 minutes and  distance is 1.32 miles

Speed = \frac{Distance}{time}

Speed = \frac{1.32}{11}

speed  = 0.12

CASE 4:

When time is 14 minutes and  distance is 1.68 miles

Speed = \frac{Distance}{time}

Speed = \frac{1.68}{14}

speed  = 0.12

CASE 5:

When time is 17 minutes and  distance is 2.04 miles

Speed = \frac{Distance}{time}

Speed =\frac{2.04}{17}

speed  = 0.12

CASE 6:

When time is 20 minutes and  distance is 2.4 miles

Speed = \frac{Distance}{time}

Speed =\frac{2.4}{20}

speed  = 0.12

In all the cases we get the speed as 0.12

Hence the  equation can be

d = 0.12 m

where d is the distance(in miles) and m is the time(in minutes)

Convert r^2 sin(2 theta) = 4 to Cartesian form.
lora16 [44]
Hello,

xy=2 is the cartesian form.

Indeed:
x=r cos t ==>cos t=x/r
y=r sin t ==> sin t=y/r
r²*sin 2t=4  ==>r²*2 sin t cos t=4
==>r²*x/r*y/r=2==>xy=2
