Answer:
the size of the bacterial population after 100 minutes is 20,158.7 bacteria
the size of the bacterial population after 10 hours is 2097152000 bacteria
Step-by-step explanation:
Given that
The bacteria contains 2000
It would be double at every half hour
We need to find out the size of the bacteria after 100 minutes & 10 hours
So,
The size of the bacteria after 100 minutes is
= 2000 × 2^(100 ÷ 30)
= 2000 × 10.079
= 20,158.7 bacteria
Now the size of the bacteria after 10 hours is
10 hours = 10 × 60 minutes = 600 minutes
= 2000 × 2^(600 ÷ 30)
= 2097152000 bacteria

Answer:
See attached photograph
Step-by-step explanation:
It is a simple matter of subtracting 1 from the given x value. For example, when x=3 we need to subtract 1 away from it to find f(x); so, f(x)=2.
Side note: the term "f(x)" means "y", so when plotting this information on a graph, you will use the f(x) column as your y value.

Jaxon made 12 shots in five minutes during practice, and he consistently shoot the same, how long did it take him to make 5 shots?
Step-by-step explanation:
12 shots in 5 minutes.
12/5 ratio.
how long for 5 shots ? x minutes
5/x must be the same ratio as 12/5
so,
5/x = 12/5
25/x = 12
25 = 12x
x = 25/12 = 2 1/12 ≈ 2.08 minutes =
= 2 minutes and 5 seconds
(60 seconds per minute divided by 12 = 5)
Brandon has a total of 187 postage stamps in his collection.
• he has 48 stamps that are each 14 millimeters wide.
• he has 139 stamps that are each 12 millimeters wide.
what is the total width of the stamps in Brandon's collection?
please help!
Answer:
233.4 Centimeters
Step-by-step explanation:
48 x 10 = 480
48 x 4 = 192
480 + 192 = 672
139 x 10 = 1390
139 x 2 = 272
1390 + 272 = 1662
1662 + 672 = 2334
2334mm = 233.4cm
To rent a taxi in Los Angeles, the taxi service charges a flat rate of $11.20 and an additional $3.10 per mile driven. Write an equation in slope- intercept form where x represents the distance of the trip, and y represents the amount the taxi service would charge to drive that distance .
Answer:
y = 3.1x + 11.2Step-by-step explanation:
Flat rate is the y- intercept b = 11.2
Charge per mile is the slope m = 3.1
The equation is:
y = 3.1x + 11.2the side lenghts of a triangle are 14,15, and x units
9514 1404 393
Answer:
1 < x < 29
Step-by-step explanation:
The triangle inequality requires the sum of the two shortest sides exceed the longest side.
When x and 14 are the shortest:
x + 14 > 15
x > 1
When 14 and 15 are the shortest:
14 +15 > x
29 > x
Then the requirement for the length of x is ...
1 < x < 29

Additional comment
The length of the third side of a triangle can be between the difference and sum of the two given sides.
Does the graph represent a function? Why or why not?
Answer:
Yes
Step-by-step explanation:
Because any vertical line drawn doesn't meet the graph at two points.
So this concludes that there is a single output for any input. Which is the basic requirement for a function

Answer:
Step-by-step explanation:
2500 +625+625+2500=6250
There are 6250 square feet inches total
625 square ft
625 = 1/10 {proportion}
6250
6000x 1/10
= 600
apportioned cost = {$600}
if 6/10 = 21/K what is K
You can cross multiply for this problem. So:
[tex]\frac{6}{10}=\frac{21}{K}\\6K=210\\K=35[/tex]
So K=35!
Hope this helps! :)
a regular pentagon is divided into 5 isoscleles triangles work out the size of angle x angle y angle z
x = 72
y = 54
z = 54
================================================================
The regular pentagon has all five sides the same length. It also has all interior angles the same measure. This leads to y = z. These two angles are the congruent base angles of the isosceles triangle. The base angles are opposite the congruent sides.
The fact that we have a regular pentagon also means that the five triangles shown are identical copies of one another (i.e. they are congruent triangles). Divide the full 360 degree rotation into 5 parts to get 360/5 = 72, which represents the measure of the central angle x.
--------------
For any triangle, the three angles always add to 180. This means,
x+y+z = 180
72+y+z = 180 .... plug in x = 72
72+y+y = 180 ... recall that y = z
2y+72 = 180
2y = 180-72
2y = 108
y = 108/2
y = 54, which is also the measure of angle z as well
--------------
As a quick check,
x+y+z = 72+54+54 = 180
which helps confirm the answer.

3.7.5 Practice: Modeling: Pumpkin Launch
Answer:
(Go with the melon, tomato, or pumpkin)
Step-by-step explanation:
MELON: I chose the melon. The target is 40ft away, so the maximum height of the launch has to be 12 feet.
TOMATO: I chose the tomato (because the numbers are round and easy to manipulate) The target is 60ft away, so the maximum height of the launch has to be 45 feet.
PUMPKIN: I chose the pumpkin. The target is 50 ft away, so the maximum height is 62 feet.

y is inversely proportional to x2.
When x = 5, y= 16.
Find y when x= 10.
Since y is inversely proportional to [tex]x^2[/tex], the value of y, when x = 10 is 4.
Given the following data:
x = 5y = 16To find the value of y, when x = 10:
Mathematically, translating the inverse relationship between x and y, we have:
[tex]y \;\alpha\; \frac{1}{x^2} \\\\y \;= \frac{k}{x^2}[/tex]
Substituting the given parameters into the formula, we have;
[tex]16 = \frac{k}{5^2} \\\\k = 16 \times 25[/tex]
k = 400
Now, we can find the value of y, when x = 10:
[tex]y = \frac{400}{10^2} \\\\y = \frac{400}{100}[/tex]
y = 4

Answer:
Based on the graphs shown, what would you conclude about the conditions under which enzymes function in cells?
A
Enzymes are most effective at a particular pH and temperature but can function over a range of pH and temperature.
B
С
Enzymes do not have a specific pH or temperature at which they are most effective but function optimally over a range of pH and temperature.
Enzymes work equally well at the low and high ends of their temperature range but reaction rate drops quickly at the high end of their pH range
Enzymes only function at a specific pH and temperature and cannot function over a range of pH or temperature.

Answer:
First number line: 3rd line from 0
Second number line: 7th line from 0
(Sorry if I explained it kinda weird, hope this helps!)
Step-by-step explanation:
On the first number line, you would put the dot on the 3rd line from zero. From 0 to one, it's split into 5 equal parts. 0 is 0/5 and 1 is 5/5. So all you do is plot the dot on 3/5, or the 3rd line from 0.
Same thing with the second number line. Except for this time, it's split into 8 equal parts. Just count to the 7th line in between 0 and 1 and plot the dot.
One angle of an isosceles triangle is known to be 68°. What would be one of the other angles?
a 44°
b 55°
c 66°
d 112°
Answer:
44
Step-by-step explanation:
Isosceles triangles have two angles that are equal. If the two equal angles are 68
We have 68, 68, and an unknown angle x
They add to 180
68+68+x = 180
136+x=180
x =180-136
x =44
