Answer:
The equation is  at a rate of -23%.
  at a rate of -23%.
Step-by-step explanation:
Decay can be represented by the equation  . We can find the rate at which it decays by using t=3 hours and A=3000. This means
. We can find the rate at which it decays by using t=3 hours and A=3000. This means  in this context.
 in this context.
 
 
After substituting, we divided by 6000 to each side to get 0.5 on the left. Now to solve for r, we will take the natural log of both sides and use log rules to isolate r.
 
We know  so we were able to cancel it out and divide both sides by 3.
 so we were able to cancel it out and divide both sides by 3.
We solve with a calculator  
We change -0.23 into a percent by multiplying by 100 to get -23% as the rate.
The equation is

The intersecting secant theorem states the relationship between the two intersecting secants of the same circle. The given problems can be solved using the intersecting secant theorem.
<h3>What is Intersecting Secant Theorem?</h3>
When two line secants of a circle intersect each other outside the circle, the circle divides the secants into two segments such that the product of the outside segment and the length of the secant are equal to the product of the outside segment other secant and its length.
a(a+b)=c(c+d)
1.)
6(x+6) = 5(5+x+3)
6x + 36 = 25 + 5x + 15
x = 4
2.)
4(2x+4)=5(5+x)
8x + 16 = 25 + 5x
3x = 9
x = 3
3.)
8x(6x+8x) = 7(9+7)
8x(14x) = 112
112x² = 112
x = 1
4.)
(x+3)² = 16(x-3)
x² + 9 + 6x = 16x - 48
x² - 10x - 57 = 0
x = 14.0554
