What is described as the exponent?A symbol compiled above and on the right of a mathematical equation to represent the operation of increasing to a power.In scientific notation, we are calculating the quotient of the expression below.As, per the given question,
The equation stated can be written as;
= (9.6×10⁻⁸)/(3.2×10⁴)
Use the power rule of exponents;
= (9.6×10⁻⁸×10⁻⁴)/(3.2)
Add both the power of base 10 with sign as the same base is there.
= ((9.6×10⁻⁸⁻⁴)/(3.2)
= (9.6×10⁻¹²)/(3.2)
Divide the numerator by 3.2
= 3.0×10⁻¹²
The following conclusions are possible:
B.The solution's power of ten is -12, which is the difference of the original exponential function.

A person's systolic blood pressure, which is measured in millimeters of mercury (mm Hg), depends on a person's age, in years. The equation
p=0.007y^2-0.003y+122
gives a person's blood pressure, p,at the age y year
A.) Find the systolic pressure, to the nearest tenth of a millimeter, for a person of age 41 years.
The systolic pressure, to the nearest tenth of a millimeter, for a person of age 41 years is; 133.6 mm Hg
How to solve problems using quadratic equations?We are given the equation that gives a person's blood pressure, p at the age y year is;
p = 0.007y² - 0.003y + 122
To find the systolic pressure for a person of age 41 years, just plug in y = 41 into the given quadratic equation to get;
p(41) = 0.007(41)² - 0.003(41) + 122
p(41) = 11.767 - 0.123 + 122
p(41) = 133.6
Thus, the systolic pressure, to the nearest tenth of a millimeter, for a person of age 41 years is; 133.6

If you have the function f(x) = 5^x - 5 then find the value of f(t)
The value of the function is [tex]5^t-5[/tex] .
A function is defined as a expression containing one or more variables.
A function, in technical terms, is a mechanism to connect a collection of inputs to a set of outputs.
A function of a single variable (say x) is defined mathematically as g(x).
Let us consider a function of a variable x such that it is defined as:
g(x)=x+1
Here the output are calculated for all values of x . At x=1 the value of the function is denoted as g(1)=1+1=2.
Mathematically to calculate the value of the function f(x) for any particular value of x we substitute the value of x into the value of f(x).
Now the given function is given as:
[tex]f(x)=5^x-5[/tex]
Therefore at x=t,
[tex]f(t)=5^t-5[/tex]

How many milliliters of a 28% sugar Solution do we need to mix with 75 milliliters of a 10% sugar solution so that the resulting mixture is a 13% sugar solution?
We need to mix 15 ml of 28 % of solution to get the resulting mixture as a 13 % sugar mixture.
Let the amount of 28 % sugar solution be x ml.
We are given that:
10 % sugar solution = 75 ml
Total solution = 75 ml + x ml
We need the solution to be 13 % sugar solution.
So, we get that:
28 % x + 10 % ( 75 ) = 13 % ( 75 + x )
28 x + 750 = 13 ( 75 + x )
28 x + 750 = 975 + 13 x
28 x - 13 x = 975 - 750
15 x = 225
x = 225 / 15
x = 15
Therefore, we need to mix 15 ml of 28 % of solution to get the resulting mixture as a 13 % sugar mixture.

Express 6 hours 28 minutes and 16 seconds in decimal form. Round your answer to two decimal places.
Answer: 6.47 hours
Step-by-step explanation:
First, you need to change your seconds into terms of minutes.
16 seconds / 60 s in a min = .266 min
Add that to your minutes:
28+.266 = 28.266 minutes
Now convert your minutes into hours
28.266 min/60 min in an hour=.47
Add that to your hours:
6+.47= 6.47 hours total
According to a recent study, the number of prisoners in a prison decreased by 312 inmates over a one-year period. If the decrease was the
same for each of the 12 months, write the monthly decrease as a quotient of integers and find the monthly decrease.
The expression to find the monthly decrease in prisoners is.
(Do not simplify.)
The number of inmates in the prison decreased by inmates per month.
(Simplify your answer.)
Over a year, a prison's population dropped by 312 inmates. We know that 1 Year = 12 Months.
Additionally, considering that each of the 12 months declined at the same rate.
the Monthly decrease in members = 312 / 12 = 26
Therefore, the expression used to calculate the monthly drop in prisoner population = Number of prisoners decreased per year / Number of months
Note: If the monthly drop rate is the same, the aforementioned equation is correct ( for all months in that year)

Maureen knows the domain of f(x) is the set of positive real numbers if she graphs f(x) on the coordinate plane what must be true about the graph
The correct option is C, if f(x) has a domain only with positive values, the graph will be on the first and fourth quadrant.
What must be true about the graph?We know that the domain of f(x) is only the set of positive real numbers. Now remember that the domain of a function is the set of the inputs of that function (the inputs are on the horizontal axis).
Then the graph of f(x) will only be on the positive side of the horizontal axis. We know that the two quadrants that are on that region are the first quadrant and the fourth quadrant.
Then if f(x) has a domain only with positive values, the graph will be on the first and fourth quadrant, this means that the correct option is C.

The two distances are the same (out and back),
so set them equal.
That distance is cover by having one is (rate)(time) equal to other is (rate)(time).
Let,
One time is “x” and the other is “4.8-x.”
One average rate is 460 per hour
and the other average rate is 500 per hour.
we know , Speed = [tex]\frac{distance}{time}[/tex]
so , distance = speed × time
put in this formula we get the value of X
⇒460 x = 500 (4.8 -x)
⇒460 x = 2400 - 500x
⇒900 x = 2400
⇒x = 2.5 hours for the slower plane.
⇒4.8- x = 2.3 hours for the faster plane.
The formula speed = distance ÷ time can be rearranged, just like any other equation.
Here detail explanation about relation between speed distance and time :

Which is the least whole number that rounds to 2000 when rounded to the nearest hundred
The required number is 2001.
To solve this problem we need to know the concept of rounding off.
Rounding off a number means making the value of number equal to the nearest tens place.
When we round off 45 we will get 50; when we round off 44 we get 40.
So, if a number has 5 at its unit place then it will be rounded off to the tens place which is ahead of 5 and if a number is less than 5 then it is rounded off to the tens place before that number.

50% of women who said ‘no’ out of the total survey population if 15 men and 75 women were asked if they had seen the company’s latest TV advertisement.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
Market research was undertaken to determine whether an ad campaign was successful for the software company.
Total number of people = 15 + 75 = 90
The number of people who said yes = (2/5)90 = 36
The number of people who said no = 90 - 36 = 54
The number of men said yes = (6/15)x15 = 6
The number of men said No = 15 - 6 = 9
The number of women who said no = 54 - 9 = 45
Percentage = (45/90)x100
The percentage of women who said ‘no’ out of the total survey population:
= 50%
Thus, 50% of women who said ‘no’ out of the total survey population if 15 men and 75 women were asked if they had seen the company’s latest TV advertisement.
