Answer:

  C = πd = 2πr

  1. C = 18.84 m

  2. C = 43.96 ft

Step-by-step explanation:

The formula to find the circumference is C = πd = 2πr.

__

1. C = 2π(3 m) = 6π m = 6(3.14) m = 18.84 m

__

2. C = πd = (3.14)(14 ft) = 43.96 ft

Write the equation of the line parallel to x = 7 which passes through (0, 1).
torisob [31]

Answer:

x = 0

Step-by-step explanation:

If the line is parallel to x = 7, it will also be a vertical line.

Vertical lines will only have one possible x-value, and since the line passes through (0, 1), this means the vertical line goes through the x value 0.

The equation of the line will be x = 0

A population of 1200 rabbits increases by 2.5% each year. At the end of 5 years, there will be approximately 1,358 rabbits in th
lubasha [3.4K]

Answer: y= 1200 (1.025)^t

Step-by-step explanation:

Hi, to answer this question we have to apply an exponential growth function:

A = P (1 + r) t  

Where:

p = original population

r = growing rate (decimal form)

t= years

A = population after t years

Replacing with the values given:

1200= 1200 (1+ 2.5/100)^5

1200= 1200 (1+ 0.025)^5

1200= 1200 (1.025)^5

For the number of rabbits, y, at the end of t years

y= 1200 (1.025)^t

Feel free to ask for more if needed or if you did not understand something.
