Answer:
(x + 1)² + (y - 1)² = 16
Step-by-step explanation:
Since the standard form for an equation of a circle is
<h3>
(x - h)² + (y - k)² = r²</h3>
The (h,k) are co-ordinate of your centre of circle, which in this case is (-1,1) and r is the radius of circle.
As we can see in the figure radius = 4units
<em>from centre(1,-2) to (1,-2)</em>
Put these into the equation
(x + 1)² + (y - 1)² = 4²
(x + 1)² + (y - 1)² = 16

Answer:
- 2% growth per year
- 25,000 to start
- 12 years
- 31,706 currently
Step-by-step explanation:
The base of the exponent is (1 +0.02). The value 0.02 = 2% is the growth rate. It is positive, signifying a 2% rate of growth per year. (Negative values would mean decay.)
The number 25000 that multiplies the exponential term is the value of the expression when the exponent is zero. It represents the starting population.
The exponent is said to be in years, so the time is 12 years.
The current population is the value of the expression:
25,000(1.02^12) ≈ 31,706 . . . . current population
Janice estimate was that it was under by approximately 0.6
units to the actual length of the triangle as she was examining the given
triangle with an estimation that the longest side has a length of 25 units―if
it is a right triangle.
Answer:
<u>1/4</u>
Step-by-step explanation:
if you take the fraction 3/12 and divide it by 3 on both sides, you get the remaining fraction 1/4
