Answer: 
are the required points.
or (18.124,0) and ( -6.124,0) are the required points.
Step-by-step explanation:
Let (x,0) be the point on x -axis that are 14 units from the point (6,-7) .
Then by distance formula , we have
![\sqrt{(x-6)^2+(0-(-7))^2}=14\ \ \ [\ \because distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}]](https://tex.z-dn.net/?f=%5Csqrt%7B%28x-6%29%5E2%2B%280-%28-7%29%29%5E2%7D%3D14%5C%20%5C%20%5C%20%5B%5C%20%5Cbecause%20distance%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D%5D)
Taking square on both the sides , we get
Using quadratic formula : 
so, are the required points.
since 
so, 
are the required points.
i.e. (18.124,0) and ( -6.124,0) are the required points.
Answer:x = 6
Step-by-step explanation:
Answer:
19.
h=0, the result is 1000×2⁰ = 1000
this is the population of bacteria the excitement started with at the very beginning.
h=-3, the result is 1000×2-³ = 1000/(2³) = 1000/8 = 125
this is a calculation 3 hours backwards from the very start of the experiment, saying that if we started the experiment 3 hours earlier, this would have had to be the starting population of the bacteria so we would arrive at the same amount of population at any given time (value of h).
20.
D 25x⁶
Step-by-step explanation:
for 19 there is not more explanation. it is all ashtray in the answer.
for 20 we see that we are dealing with a square, so ask 4 sides have the same length.
one side is 5x³.
the area of a square is simply side².
so, here (5x³)² = 25x⁶
Answer:
I think it is 2
Step-by-step explanation:
AD is 2. AD is congruent to DC. So that means y = 2. I am not completely sure though.
