Turn the information into coordinate points.

Point = (time, population)

Point 1 = (1985, 45000)
Point 2 = (2004 , 26000)

Find the slope between these points using the formula

( Slope)—> m = (y2 - y1) / (x2 - x1)
26000-45000/2004-1985=-19000/19= -1000
Average rate of change is decrease of 1000 sea lion per year

I hope that helped

Solve the following system y= x+ 3 3x +y = 19
Ratling [72]
3x+y=19

y=19-3x and y=x+3, at a solution both x and y are equal so we can say y=y:

19-3x=x+3

19-4x=3

-4x=-16

x=4, and since y=x+3

y=7  so the solution is the point:

Find the square root of the following using division method . iv) 36360
sveticcg [70]

Answer:

190.684

Step-by-step explanation:

To find the square root of 36360, we place a bar over the numbers that we want to find their square root in pairs

    ,    1       \dot{3} \overline{63}  \overline{60}

       , 1       1

2,       <u>9</u>      2  \overline{63}

         9      261  

38,      <u>0</u>            2 60

          0            0

         .    

380,    6            26000

        ,  6           22800

3806,  8          320000

         ,  8          304480

38068, 4       1552000

           ,4

Which gives 190.684

3             63 60

We select the divisor to be the largest number which when squares will be equal to the largest number on the left which is 1

We have 1 * 1 = 1

We subtract it from the 3 to get 2

We add the 1's to get 2

We bring down the next pair which is 63 to form the next dividend, 263

We look for a number which will multiply itself to get 263, which is 9, we then have 29 × 9 = 261

We continue till we arrive at the vertical paired numbers which is 190.684.
