Answer:
(x - 7)² + (y - 3)² = 5
Step-by-step explanation:
The center (h , k) is the midpoint of two end points of diameter
h = (9 + 5) / 2 = 7
k = (4 + 2) / 2 = 3
Equation of circle: (x - h)² + (y - k)² = r²
r = (√(9 - 5)² + (4 - 2)²) / 2 = √5
Equation: (x - 7)² + (y - 3)² = 5
25% of 180 is 45.
You do the equation 25%*180 which equals to 45. The word of means multiply and the word is means equal
Answer:
6.2 x 10^10
Step-by-step explanation:
For this case we have an equation of the form:
Where,
A: initial amount
b: growth rate
t: time in years.
Substituting values we have:
By the time the population is triple we have:
Rewriting we have:
Clearing t we have:
Answer:
It will take for the population to triple about:
t = 73 years
Answer:
Slope intercept form:y=mx+c
y=1/2x-7
