So, these are actually pretty simple once you learn the equality used to solve for "x" and when to implement this method. You can use this equality to solve for a segment "x" anytime that two secant lines cutting through a circle come from the same point outside the circle.
Secant: by geometric definition is just a straight line that cuts a curve into multiple pieces.
I did one of them for you hopefully you can use my work for "a" to help you solve for "b".
For a. I got x=7.
A) P( Jordan finishes before Jacobs)= 2/5 = 0.40
P( Jacobs finishes before Julia) = 3/5 = 0.60
P(Jordan finishes before Jacobs AND before Julia) = 0.40 x 0.60 = 0.24
b)P( Jordan finishes before Jacobs)= 2/5 = 0.40 (already calculated
When solving logarithmic/natural log equations, the strategy is to get ln (x) alone on one side, and all the stuff on the other side. Then exponentiate both sides to get to x.
2 ln (x + 3) = 0
ln (x + 3) = 0
At this point, we can't isolate anymore or use logarithm properties to separate this further. But we have ln (something), and we can exponentiate.
x+3 = 1 <--This come from the fact the ln (x) and 
are inverse functions that undo each other. This is why exponentiating works.
x = -2
So x = -2 is our solution.

Well, the equation is 700+15x=1000
700+15x=1000
15x=300
x=20

Please, please give brainliest, it would be greatly appreciated, I only a few more before I advance, thanks!
Answer:
The domain is all real numbers less than or equal to two-third
Step-by-step explanation:
<u><em>The question in English is</em></u>
Determine the domain of the function f :D→R, 
we know that
The radicand of the function must be greater than or equal to zero
so
Solve the inequality for x
subtract 2 both sides
Multiply by -1 both sides
Divide by 3 both sides
The solution is the interval ----> (-∞,2/3]
therefore
The domain is all real numbers less than or equal to two-third
