A herd of caribou is moved to a small, remote island where they have no predators. Data on the population of the herd was collected for 6 years. (0, 29), (1, 32), (2, 47), (3, 74), (4, 113), (5, 164), (6, 227) *The x-coordinate represents the time (years) and the y-coordinate represents the population Using the equation for the curve of best fit (rounded to the nearest tenth), predict the population of the herd after 7 years.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

thats not a system of equations, that is a solution
