The number of bacteria doubling every 28 hours will be 1145 after 13 hours.
What is the formula for exponential growth and exponential decaying function?The formula for exponential growth is y = y₀.e^(kt).
The formula for exponential decay is y = y₀.e^(-kt).
In the case of doubling the growth of bacteria, we can use the formula,
[tex]y_f = y_0\times2^{\frac{t_r}{t}[/tex], where [tex]y_f[/tex] represents the final population, [tex]y_0[/tex] is the initial population, [tex]t_r[/tex] is the time we are required to determine, and [tex]t[/tex] represents the time rate growth.
Therefore from the given information, the number of bacteria after 13 hours will be,
[tex]y_f = 830\times2^{\frac{13}{28}[/tex].
[tex]y_f = 830\times1.38[/tex].
[tex]y_f = 1144.86[/tex] or 1145 bacterias.
Q. In a lab experiment, 830 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 28 hours. How many bacteria would there be after 13 hours, to the nearest whole number?

Answer:
B) 7.2 cm / 22.61 cm
Step-by-step explanation:
6.28 / 2 = 3.14
3.14 x 7.2 = 22.608 = 22.61
Circumference = 7.2
Diameter = 22. 61

Answer:
194527.41792
Step-by-step explanation:
Volume for each rod: 1130.97336
Multiply the volume by 172:
1130.97336 x 172 = 194527.41792
And that's your answer
Let the function f(x) have the form f(x) = Acos(x-C). To produce a graph that matches the one shown below, what must the value of C be?
Answer: Option B, C = 3.
Step-by-step explanation:
Here we have the function:
f(x) = A*cos(x - C)
A is the amplitude, and we can easily see that the amplitude is 2.
Then:
f(x) = 2*cos(x - C)
We also can see that when x = 0, f(x) ≈ -2
This means that:
cos(0 - C) ≈ -1
Cos(C) ≈ -1
Now we can just evaluate in the different options and see which one is the correct option.
Cos(1) = 0.54
Cos(2) = -0.42
Cos(3) = -0.99
Cos(4) = -0.65
The closer option to -1 is when C = 3, then the correct option is option B.

B

I bought four bags of cotton candy for $1.50 each and two soft drinks for 90 cents each. What was my change from a ten dollar bill
Answer:
Your change is $2.20
Step-by-step explanation:
4 x $1.50 = $6
2 x $.90 = $1.80
$6 + $1.80 = $7.80
$10 - $7.80 = $2.20
So it's $2.20. Have a nice day :D
Answer:
$2.20
Step-by-step explanation:
4 bags of cotton candy
$1.50 x 4 = $6.00
2 soft drinks
$0.90 x 2 = $1.80
$6.00 + $1.80 = $7.80
$10.00 - $7.80 = $2.20

Find the area. The figure is not drawn to scale. Hint: Find the sum of the areas of 2 triangles and 2 parallelograms.
Select one:
a. 188 in.2
b. 278 in.2
c. 322 in.2
d. none of these
Answer:
d. None of the above
Step-by-step explanation:
✔️Area of triangle 1 = ½*b*h
b = 11 in.
h = 3 in.
Area of triangle 1 = ½*11*3 = 16.5 in.²
✔️Area of triangle 2 = ½*b*h
b = 8
h = 9
Area of triangle 2 = ½*8*9 = 36 in²
✔️Area of parallelogram 1 = b*h
b = 11 in.
h = 9 in.
Area of parallelogram 1 = 11*9 = 99 in.²
✔️Area of parallelogram 1 = b*h
b = 9 in.
h = 11 in.
Area of parallelogram 2 = 9*11 = 99 in.²
✅Total area = 16.5 + 36 + 99 + 99 = 250.5 in.²

Given:
AD is an angle bisector in triangle ABC. [tex]m\angle CAB=44^\circ, m\angle ACB=72^\circ, m\angle ABC=64^\circ[/tex].
To find:
The value of [tex]m\angle ADC[/tex].
Solution:
AD is an angle bisector in triangle ABC.
[tex]m\angle CAD=m\angle BAD=\dfrac{m\angle CAB}{2}[/tex]
[tex]m\angle CAD=m\angle BAD=\dfrac{44^\circ}{2}[/tex]
[tex]m\angle CAD=m\angle BAD=22^\circ[/tex]
According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees.
Using angle sum property in triangle CAD, we get
[tex]m\angle CAD+m\angle ADC+m\angle ACB=180^\circ[/tex]
[tex]22^\circ+m\angle ADC+72^\circ=180^\circ[/tex]
[tex]m\angle ADC+94^\circ=180^\circ[/tex]
[tex]m\angle ADC=180^\circ-94^\circ[/tex]
[tex]m\angle ADC=86^\circ[/tex]
Therefore, the angle of angle ADC is [tex]86^\circ[/tex].

What is 70 + 4 rounded to the nearest ten?
Answer:
Step-by-step explanation:
We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4. If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.
