How do exponential functions differ from regular functions? In exponential functions the variable is: a. always negative c. representing the power b. representing the base d. always t Please select the best answer from the choices provided A B C D
In exponential functions, the variable is that which is in the exponent and whose base is always greater than zero and different from one.
What is exponential Function?An exponential function is a mathematical function used to calculate the exponential growth or decay of a given set of data.
We know that a variable in an exponential function is one whose exponent is always larger than zero and whose base is not one.
These limitations are required since 1 increased to any number equals 1. As a result, we would be faced with a regular function rather than an exponential one.
Additionally, because some exponents would result in the function not being defined, the basis of the exponential function cannot be negative or equal to zero.

how long is 90 minutes
90 minutes is about 5400 seconds long or 1.5 hours long.
What is time ?Time is the ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future.
The minute is a measure of time that is typically equal to 60 seconds, or 1/60 of an hour. Because to leap seconds, a minute occasionally has 61 seconds in the UTC time zone. The minute is acceptable for use with SI units even though it is not a SI unit. Minutes are represented by the SI unit min.
Depending on the speed of the Earth's rotation, an hour is a measure of time that is traditionally calculated as 1/24 of a day and scientifically estimated to last between 3,599 and 3,601 seconds. There are 24 hours in a day and 60 minutes in an hour.
The second is the International System of Units' unit of time, previously defined as 1/86400 of a day. This element came from the split of a day into 24 hours, 60 minutes, and then 60 seconds each.
So , 90 minutes can be writen as
90 * 60 = 5400 seconds
90 minutes can also be written as

The solution of the system is (2, 1).
Where is the mistake in the solution?
Here someone wants to solve the system of equations below:
2x + y = 5
3x - 2y = 4
On the first step, they isolate y on the first equation to get:
y = -2x + 5
Then they substitute that on the same equation, they get:
2x + (-2x + 5) = 5
5 = 5
That is trivial, we are replacing one equation into itself.
The substitution method needs to replace that on the other equation, so there is the mistake, then the correct option is the second.
The actual solution is given by:
3x - 2*(-2x + 5) = 4
3x + 4x - 10 = 4
7x = 4 + 10
x = 14/7 = 2

An insurance agent earns a base salary of $32,000, and a commission of 3% of his sales. He also receives an additional fee of $16. 00 for each home policy he sells. The agent has sold a total of $89,000 and 8 home policies this month. Find the commission and fees he has earned
To find the commission and fees the insurance agent has earned, we need to first calculate the 3% commission from the $89,000 in sales. This is equal to $2,670. Next, we need to calculate the additional fees from the 8 home policies sold. This is equal to $128. Thus, the total commission and fees the agent has earned this month is $2,798 ($2,670 + $128).
This commission and fees amount is in addition to the base salary of $32,000. Thus, the total earned this month by the insurance agent is $34,798 ($32,000 + $2,798). This figure is obtained by adding the base salary and the commission and fees. Note that this figure does not include any bonuses or other incentives that the agent may receive.

The value of a 45 degree angle in an isosceles right angled triangle is: 1
In an isosceles right angled triangle, where AB = BC = x, the sides AB and BC form the hypotenuse, and the remaining side AC forms one of the legs.
For the 45 degree angle (let's call it angle A), the sine function can be used to find the ratio of the opposite side to the hypotenuse:
sin(A) = opposite side / hypotenuse = AC / AB = AC / xSince the triangle is isosceles, AC = AB = x, therefore:
sin(A) = x / x = 1So the sine of a 45 degree angle in an isosceles right angled triangle is 1.
Note: The cosine and tangent of 45 degrees can also be found using the other trigonometric ratios, but since only sine was requested, I only provided the sine value.

Given that `x=10`, we can find the value of `a` and `b` by substituting the value of `x` into the given expressions for `a` and `b`.
For `a`, we have: `a = 5x^2/2`. Substituting `x=10`, we get: `a = 5(10)^2/2 = 250`.
For `b`, we have: `b = 2x^2(x-5)/10x`. Substituting `x=10`, we get: `b = 2(10)^2(10-5)/10(10) = 100`.
Therefore, when `x=10`, the value of `a` is 250 and the value of `b` is 100.

true or false. degrees of freedom are a feature of statistics when we are analyzing a sample, rather than the population.
The answer is True. Degrees of freedom are a feature of statistics that are used when we are analyzing a sample rather than the population.
The degrees of freedom (df) refers to the number of independent observations in a sample that can be used to make inferences about a population. The concept of degrees of freedom is used in many statistical methods, including t-tests, ANOVA, and regression analysis.
In simple terms, degrees of freedom can be thought of as the number of data points in a sample that are "free" to vary in order to estimate a population parameter. For example, in a sample of two measurements, only one measurement is "free" to vary since the other measurement is used to calculate the mean. Hence, the degrees of freedom would be 1.
It's important to note that when analyzing a population, there are no degrees of freedom since all of the observations are considered independent and can be used to estimate the population parameters. In contrast, when working with a sample, the degrees of freedom are reduced by the number of constraints that are imposed on the sample in order to make inferences about the population.
In summary, the degrees of freedom are a feature of statistics that reflect the number of independent observations in a sample that can be used to make inferences about the population.
Therefore, The answer is True. Degrees of freedom are a feature of statistics that are used when we are analyzing a sample rather than the population.

if f and g intersect midway between x = a and x = b then
The intersection of two functions f and g occurring midway between x = a and x = b can be calculated using the following formula: (f(x) - g(x)) = 0.
Let f and g be two functions with the domain (a,b). For f and g to intersect midway between x = a and x = b, the x-coordinate of the intersection point must be (a+b)/2. Therefore, the equation to solve is f(x) = g(x) = (a+b)/2. To solve this equation, we must first find the value of f((a+b)/2) and g((a+b)/2). Then, equate these values to each other, and solve for the variable. For example, if f(x) = x2+2x+4 and g(x) = x+7, the equation to solve is (a+b)/2 + 7 = (a+b)2/4 + 2(a+b)/2 + 4. Simplifying this equation, we get a2 - 2b2 + 2ab + 7a - 7b + 11 = 0. This equation can then be solved using the quadratic formula to find the value of a and b.

Age at natural death is an example of a real-world variable with a left-skewed distribution (heart disease, cancer, etc.). Most of these deaths occur in older people and a minority in younger people.
What are some examples of right-skewed distributions?Salary is an example of a real-world variable with a right-skewed distribution. If there are a few outliers (CEOs, professional athletes, etc.), most individuals have incomes in the low/mid range, with a wide range of higher numbers (a long "tail"). A long left tail indicates that the distribution is skewed to the left. A negatively skewed distribution is similar to a left skewed distribution. This is because the number line has a long tail in the negative direction. The average is also to the left of the peak. The left side of a left-skewed distribution is longer than the right side. That is, a left-skewed distribution has a long tail on the left.
