If the initial population of the bacteria is 100, then the population of the bacteria after 180 hours will be 800.
What is an exponent?Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. X is the base and n is the power.
A colony of 100 bacteria doubles in size every 60 hours.
The exponential relation will be given below.
[tex]\rm P = 100 \times 2^{t/60}[/tex]
Where t is the number of hours
Then the population of the bacteria after 180 hours will be
[tex]\rm P = 100 \times 2^{t/60} \\\\P = 100 \times 2 ^{180/60}\\\\\rm P = 100 \times 2^{3}\\\\\rm P = 100 \times 8\\\\\rm P = 800[/tex]

A bird drops a stick to the ground from a height of 70ft. The function h = -16t^2 + 70 gives the stick's approximate height h above the ground, in feet, after t seconds. Graph the function. At about what time does the stick hit the ground?
Answer:
√ 80/16=t t=0.5590169943749474
Step-by-step explanation:
The function h(t) = -16t^2 + 70 is a quadratic function, and the stick hits the ground at about 2.092 seconds
Here, we have,
to determine the time it hits the ground:
The function is given as:
h(t) = -16t^2 + 70
Next, we plot the graph of the function h(t)
From the graph of the function h(t) (see attachment), we have the following highlight:
t = -2.092 and t = 2.092 when h(t) = 0
Time cannot be negative.
So, we have:
t = 2.092
This means that the stick hits the ground at about 2.165 seconds

E. 7
Step-by-step explanation:
General form of exponential equation: [tex]y=ab^x[/tex]
where [tex]a[/tex] is the initial value, [tex]b[/tex] is the growth/decay rate, and [tex]x[/tex] is time.
Given:
[tex]a[/tex] = 100 bacteria[tex]b[/tex] = 25% increase = 1.25[tex]x[/tex] = number of days⇒ [tex]y=100 \cdot 1.25^x[/tex]
If y = 500, then:
[tex]\implies 500=100 \cdot 1.25^x[/tex]
[tex]\implies 5=1.25^x[/tex]
[tex]\implies \ln5=\ln1.25^x[/tex]
[tex]\implies \ln5=x\ln1.25^[/tex]
[tex]\implies x=\dfrac{\ln5}{\ln1.25}[/tex]

You open a brand-new savings account January 1, 2021. Every paycheck you earn you deposit $25 into a savings account, and you never make any withdrawals from this account. Your savings account makes 0.01% interest and is compounded monthly. Assuming you get paid every two weeks (twice a month) how much money will you have at the end of the year?
The amount of money that you will have at the end of the year from your brand-new savings account is $600.69.
What is future value?The future value is the value of periodic cash flows in the future. It can be computed using an online finance calculator as follows:
Data and Calculations:N (# of periods) = 24 (12 X 2)
I/Y (Interest per year) = 0.12% (0.01% X 12)
PV (Present Value) = $0
PMT (Periodic Payment) = $25
Results:
FV = $600.69
Sum of all periodic payments = $600.00 ($25 X 24)
Total Interest = $0.69
Thus, the amount of money that you will have at the end of the year from your brand-new savings account is $600.69.

ロThe missing side measures 12.5 ft.
ロ The missing side of the fence measures 15 ft.
ロ The perimeter of the fence is 40 ft.
ロ The perimeter is 37.5 ft.
ロ The area inside the fenced in section is 60 sq ft
ロ The area inside the fenced section is 68 sq ft.
The missing side of the fence measures 15 ft
The perimeter of the fence is 40 ft
The area inside the fenced in section is 60 ft²
The fence is triangular and a right triangle.
Right triangle:A right triangle has one of its angle as 90 degrees. Therefore, the sides can be found using Pythagoras theorem.
c² = a² + b²
17² - 8² = b²
b = 15 ft
AC = 15 ft
perimeter of the triangle = 15 + 8 + 17 = 40 ft
Area of the triangle = 1 / 2 × 15 × 8 = 60 ft²
Therefore,
The missing side of the fence measures 15 ft
The perimeter of the fence is 40 ft
The area inside the fenced in section is 60 ft²

What is the inequality?
The movie will be a maximum of 90 minutes long.
Answer:
it should be 1 hour 30 min long (maybe)
Step-by-step explanation:
At an intersection, the red-light times are normally distributed with a mean time of 3 minutes and a standard deviation of 0. 25 minutes. Using the empirical rule, approximately what percent of red lights last between 2. 5 and 3. 5 minutes? 32% 68% 95% 99. 7%.
The red light lasts between 2.5 minutes and 3.5 minutes is 95 %. Then the correct option is C.
What is normal a distribution?It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.
At an intersection, the red-light times are normally distributed with a mean time of 3 minutes and a standard deviation of 0. 25 minutes.
In this case, the mean is 3 and the standard deviation is 0.25, We move one space to the right that would represent 3.25 minutes, one more space to the right that is 3.50 minutes. Similarly, we move one space to the left, this would be 2.75, one more space to the left, and the shows 2.50 minutes.
Thus, the correct option is C.
