Answer:
Step-by-step explanation:
Given a circle centre J
Let the radius of the circle =r
LK is tangent to circle J at point K
From the diagram attached
Theorem: The angle between a tangent and a radius is 90 degrees.
By the theorem above, Triangle JLK forms a right triangle with LJ as the hypotenuse.
Using Pythagoras Theorem:
The length of the radius, 
Hello from MrBillDoesMath!
Answer:
-52. None of the provided choices is correct
Discussion:
Following the usual order of math operations none of the provided answers is correct. The answer is
2*3 + 4- 62 = => * before + and -
(2*3) + 4 - 62= => 2*3 = 6
6 + 4 -62 = => 6 + 4 = 10
10 - 62 =
-52
Thank you,

Answer:
The answer is D
Step-by-step explanation:
= 0.8
= 2.64
2.64 > 0.8 because 2 is a whole number while 0.8 is a decimal
Answer:
- k = 0.005
- doubling time ≈ 139 years
Step-by-step explanation:
Matching the form
A = A0·e^(kt)
to the given equation
A = 8·e^(.005t)
we can identify the value of k as being 0.005.
k = 0.005
___
The doubling time is given by the formula ...
t = ln(2)/k = ln(2)/0.005 ≈ 138.63
It will take about 139 years for the population to double.
