This is the concept of exponential growth, To get the number of bacteria after 10 days we use the formula:
f(t)=ae^(kt)
where;
a=initial number=5000
k=constant of proportionality= 0.04
t=time=10 days
f(t)=future number
thus the number of bacteria in 10 days will be:
f(t)=5000e^(0.04*10)
f(t)=7,459.12
The answer is 7,459.12

We know that the culture of bacteria has 5,000 bacteria today.
Also : p = 4 %  = 0.04, and t = 10 ( 10 days from now )
The formula is:
A = P * ( 1 + p )^t
A = 5,000 * ( 1 + 0.04 ) ^10
A = 5,000 * 1.04^10
A = 5,000 * 1.48
A = 7,401
Answer: There will be 7,401 bacteria.

Find an equation of the circle that has center (−1,2) and passes through ( 2,−2) .
user100 [1]
Equation of a  circle that has a center at (h,k) and radius of r is
(x-h)²+(y-k)²=r²

so

given center (-1,2)
(x-(-1))²+(y-2)²=r²
(x+1)²+(y-2)²=r²

sub the other point to find r or r²

it passes through (2,-2)
sub 2 for x and -2 for y

(2+1)²+(-2-2)²=r²
(3)²+(-4)²=r²
9+16=r²
25=r²
5=r


the equation is
(x+1)²+(y-2)²=5²

2.50 x 4 = 10

20 - 10 = 10

so his change would be $10
