Answer:
The solution of the equation is 2.
Step-by-step explanation:
The given functions are
It is given that the graph of f(x) and g(x) intersects each other at (2,-1).
The given equation is
The solution of this equation is the value of x where both the functions are eqaul.
Since both functions are equal at x=2, therefore the solution of the equation is 2.

Answer:
-1 4/5
Step-by-step explanation:
In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole. For example, in the fraction 3 5, the numerator is 3, and the denominator is 5. A more illustrative example could involve a pie with 8 slices. 1 of those 8 slices would constitute the numerator of a fraction, while the total of 8 slices that comprises the whole pie would be the denominator. If a person were to eat 3 slices, the remaining fraction of the pie would therefore be 5 8 as shown in the image to the right. Note that the denominator of a fraction cannot be 0, as it would make the fraction undefined. Fractions can undergo many different operations, some of which are mentioned below.
the base is 3x - 5, and the argument is 16
Answer:
x=3
Step-by-step explanation:
The given equation is
The relation between logarithmic function and exponential function is given by
On comparing, we get
b = 3x-5
y = 16
x = 2
Hence, using the relation, we have
Take square root both sides
On simplifying
For x = 1/3
Base cannot be negative.
Hence, the value of x is 3
b)The original pulse rates are measured with units of "beats per minute." What are the units of the corresponding z-scores?
Answer:
a) Mean=0 and Standard deviation=1
b) The z-scores have no units of measurement
Step-by-step explanation:
When we convert all the pulse rates of women to z-scores using the formula;
the mean is 0 and the standard deviation is 1.
The reason is that, the resulting distribution of z-scores forms a normal distribution which has a mean of 0 and a standard deviation of 1.
b) The z-scores are standardize scores and has no units of measurement. They give us how many standard deviations below or above the mean of the corresponding values.
Converting pulse rates into z-scores standardizes them into a standard normal distribution, yielding a mean of zero and a standard deviation of one. Z-scores are dimensionless and do not carry original physical units of measurement.
The question is asking about the properties of a z-score in the context of pulse rates of women. Here is the answer:
a) When converting to z-scores, regardless of the population parameters, the mean (μ) will always be 0 and standard deviation (σ) always 1. This conversion process is called standardization, which results in a standard normal distribution.
b) In the context of z-scores, the units are dimensionless. Because a z-score result is derived from a mathematical manipulation and not a direct measurement, it does not carry physical units like "beats per minute" in pulse rates. This characteristic enables us to make meaningful comparisons between different types of data.

The polynomial 16a² - 4a + 4a - 1 can be simplified to a difference of squares
Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.
The difference of two squares is given by:
a² - b² = (a + b)(a - b)
Hence:
16a² - 4a + 4a - 1 = 4a(4a - 1) + 1(4a - 1)
= (4a + 1)(4a - 1)
The polynomial 16a² - 4a + 4a - 1 can be simplified to a difference of squares
