Answer:
y = 52
Step-by-step explanation:
For this case we have a function of the form:
y = A * (b)^x
Where,
A: initial population of bacteria
b: growth rate
x: number of hours
Since the diameter is double every hour, then:
We must now look for the value of A.
b = 2
To do this, we evaluate an ordered pair of the graph:
For (1, 2):
2 = A * (2)^1
Clearing A we have:
2 = A * 2
A = 2/2
A = 1
Then, the function is given by:
y = 1 * (2)^x
For after 9 hours we have:
y = 1 * (2)^9
y = 512
I hope this helped. I am sorry if you get this wrong.
A right triangle? because it has angle measures or 45, 45, 90.
Let m = measure of each interior angle of a regular polygon
It turns out that
m = [180*(n-2)]/n
where n is the number of sides
We have n = 9 sides, so
m = [180*(n-2)]/n
m = [180*(9-2)]/9
m = [180*7]/9
m = 1260/9
m = 140
Each interior angle is 140 degrees
Answer: D) 140
Answer:I'm guessing there's a simpler solution, but let's give it a shot.
Step-by-step explanation:
The two roots are provided by using the quadratic equation:
x = [-b ± √(b2 - 4ac)] / (2a)
For x2 - 10x + q = 0
a = 1
b = -10
c = q
Substituting these values in:
x = [-b ± √(b2 - 4ac)] / (2a)
= [-(-10) ± √((-10)2 - 4(1)(q))] / (2(1))
= [10 ± √(100 - 4q)] / 2
= 0.5 [10 ± √(100 - 4q)]
The first root, x1
x1 = 0.5 [10 + √(100 - 4q)]
= 5 + 0.5√(100 - 4q)
The second root, x2
x2 = 0.5 [10 - √(100 - 4q)]
= 5 - 0.5√(100 - 4q)
The difference in the roots is 6.
6 = x1 - x2
= [5 + 0.5√(100 - 4q)] - [5 - 0.5√(100 - 4q)]
= 5 + 0.5√(100 - 4q) - 5 + 0.5√(100 - 4q)
6 = √(100 - 4q)
(6)2 = [√(100 - 4q)]2
36 = 100 - 4q
-64 = -4q
q = 16
Do a little more work to determine the roots.
x2 - 10x + q = 0
x2 - 10x + 16 = 0
(x - 8)(x - 2) = 0
x = {2, 8}
8 - 2 = 6
