How do you tell if a log function is increasing or decreasing?
If the derivative of the function is positive, the function is increasing; if the derivative is negative, the function is decreasing.
What is a logarithmic function?
A logarithmic function is a type of mathematical function that expresses the power to which a given number (the base) must be raised in order to produce a certain value. It is typically written in the form: [tex]f(x) = log_b(x),[/tex] where b is the base of the logarithm.
To determine whether a logarithmic function is increasing or decreasing, you can look at the sign of the derivative of the function. If the derivative is positive, the function is increasing; if the derivative is negative, the function is decreasing.
In the case of logarithmic functions, the derivative of [tex]f(x) = log_b(x)[/tex] is f'(x) = 1/x*ln(b), which is always positive for x > 0, so the logarithmic function is increasing for any base b.
Hence, if the derivative of the function is positive, the function is increasing; if the derivative is negative, the function is decreasing.

A large consumer goods company ran a television advertisement for one of its soap products. On the basis of a survey that was conducted, probabilities were assigned to the following events. The probabilities assigned were , , and a. If an individual recalls seeing the advertisement, what is the probability that the individual purchased the product (to 1 decimals)
0.30 is the probability that the individual purchased the product
What is probability?A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.
The proportion between the total number of conceivable outcomes and the number of outcomes in a comprehensive collection of equally probable alternatives that result in a particular occurrence.
Example: When flipping a coin, there are only two possible outcomes: either it will land on its head or on its tail.
Let, B = individual purchased the product
S = individuals recalls seeing the advertisement.
Here, P(B) = 0.20
P(S) = 0.40
P(B ∩ S) = 0.12
Thus, P(B | S) = P(B ∩ S) / P(S)
= 0.12/0.40
= 0.30
P(B) = 0.20 < P(B | S) =0.30
Yes, thus the probability that an individual will purchase the product will increase if the individual sees the advertisement first.

:The temperature over the course of a day was being monitored. In the morning, the temperature was −3°F. In the middle of the day, the temperature rose to 12°F. After dark, the temperature dropped again to −6°F.
What was the average temperature for the day?
Responses
−3°F
negative 3 degrees F
−1°F
negative 1 degrees F
1°F
3°
Answer:
Step by step explanation:
To find the average temperature, you take the three different temperatures you had throughout the day and divide them by how many different kinds there are. (3).
This means that the average is 1°F. This is because you have to add -3 + 12 + (-6) = 3.
Then you have to divide 3 by the amount of numbers you need to average between. In this case, you have to divide 3 by 3.
So, your final answer is:
The average temperature for the day was 1°F

The zeroes of this polynomial equation is [tex]$4 x^2-4 x-3$[/tex] are [tex]\frac{3}{2}$[/tex] and [tex]$-\frac{1}{2}$[/tex].
First form the equation
As per the given data the given polynomial equation is [tex]$4 x^2-4 x-3$[/tex].
Here we have to determine the zeroes of a polynomial equation is [tex]$4 x^2-4 x-3$[/tex].
We know that the zeroes of a polynomial are evaluated by equating them with zero.
Therefore p(x)=0
[tex]& \Rightarrow 4 x^2-4 x-3=0[/tex]
Then solve to find the zeroes
[tex]& 4 x^2-4 x-3=0 \\[/tex]
[tex]& \Rightarrow 4 x^2-6 x+2 x-3=0 \\[/tex]
2x(2x - 3) + 1(2x - 3) = 0
(2x - 3) (2x + 1) = 0
[tex]& \Rightarrow x=\frac{3}{2},-\frac{1}{2}[/tex]
Then do verification
We know that for a given polynomial [tex]$a x^2+b x+c$[/tex]
Sum of the zeroes [tex]$=-\frac{b}{a}$[/tex] and product of the roots [tex]$=\frac{c}{a}$[/tex]
Sum of the zeroes [tex]$=\frac{3}{2}-\frac{1}{2}=1$[/tex]
Again, [tex]$-\frac{b}{a}=\frac{4}{4}=1$[/tex]
Product of the zeroes [tex]$=\frac{3}{2} \times-\frac{1}{2}=-\frac{3}{4}$[/tex]
Again, [tex]$\frac{c}{a}=-\frac{3}{4}$[/tex]
Thus, the relationship between the zeroes and the coefficients of the polynomial is verified.

Option D) f(x) = -3√x+5 is the cube root function is always decreasing as x increases
What is the Formula of Cube Root Function? f(x) = x is the formula for the fundamental (parent) cube root function. After transformations, it can alternatively take the form f(x) = a (bx - h) + k. Here, the transformations are denoted by the real numbers a, b, h, and k.The symbol "" designates the cube root. For instance, 8 Equals (2 + 2 + 2) = 2. Finding the cube root of a number is simple since 8 is a perfect cube number.You need to discover a number that, when multiplied twice by itself, equals the original number in order to get the cube root of a given integer. To get the cube root of 8, then, you need to identify the integer that, when multiplied by itself twice, equals 8. Therefore, since 2 2 2 = 8, the cube root of 8 is 2.Given data :
y = ³[tex]\sqrt{x}[/tex] is an increasing function as when the value of x increases the value of y increases
And when the value of x decreases , the value of y also decreases.
Now if we have (x+a) or (x-a) instead of x, the function shall have a horizontal shift.
So it shall either move left or right but shall not flip.
So
y = ³[tex]\sqrt{(x - 8)}[/tex] and y = ³[tex]\sqrt{(x - 5)}[/tex]
are increasing functions.
Only when x becomes -x, that the function shall flip & shall become a decreasing function.
But then it must be - (x-a) or -(x+a) inside.
So
y = ³[tex]\sqrt{-(5 - x)}[/tex] is also increasing
Only
y = ³[tex]-\sqrt{(x + 5)}[/tex] is a decreasing function.

If a value has not been added, an exponential function's curve normally approaches a horizontal asymptote at y=0 or the x-axis. The curve changes if it has.
The asymptote is unaffected by this function's addition on the exponent because it does not apply to the entire function.
The values of its y-axis remain between 0 and. This is the set of y values, or the range.
However, depending on the leading coefficient, the range of exponentials can vary. If the value is negative, the graph turns inside-out and the range reaches -. It's also lacking in this.
The exponent's addition to 1 moves the function to the left without changing the range.
The x values in exponential functions are often unaffected and all are taken into account in the function. The domain stays the same even while it changes. Its range is (0,∞)
Range: (0,∞)

Thus, moving to the left, 8 times from 4.5 will help us arrive at -3.5. See attached Number line.

The simplified value of the given expression ⇒ [(-1 / 5 j) + (3 / 4) - 5 / 2j - (7 / 8)] is computed at ⇒ [(-27 / 10 j) - (1/ 5)]
An algebraic expression is one that was created in mathematics by using integer variables, constants, and algebraic operations.
However, since they are not produced by using integer constants and algebraic operations, transcendental numbers like such and e are not algebraic. The production of is commonly stated as a geometric expression, although the definition of e requires an infinite number of algebraic operations. An expression can be reduced to a rational fraction by using the properties of arithmetic operations.
You can write the given expression as:
⇒ (-1 / 5 j) + 3 / 4 - 5 / 2j - 7 / 8
When we simplify the formula and apply the fractional operations to the result, we get:
⇒ (-27 / 10 j) - (1/ 5)

Define percentage.A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
Define Fraction.Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.
Let's call the amount of time Evie practices on Tuesday T.
On Monday, she practices twice as long as she does on Tuesday, so she practices 2T minutes.
On Thursday, she practices the same number of minutes as Tuesday, so she practices T minutes.
On Saturday, she practices 5 fewer minutes than three times her Tuesday practice, so she practices 3T-5 minutes.
We know that Evie practices 310 minutes in total in a week.
So we can set up an equation:
T + 2T + T + 3T-5 = 310
7T-5 = 310
7T = 315
T = 45
On Monday, Evie practices 2T = 2*45 = 90 minutes.

Don and Ana are driving to their vacation destination. Upon entering the freeway they began driving at a constant rate of 60 miles an hour. Don noticed that 3 hours into the trip they were 650 miles from the destination.
How far from their destination will they be 3. 7 hours since entering the freeway?
How far from their destination were they 2. 3 hours since entering the freeway?
Please help quick
Distance between them and their destination after 3.7 hours since entering the freeway is 608 miles and the distance between them and their destination after 2.3 hours since entering the freeway is 692 miles.
We know that the relationship between speed, distance, and time is given as,
Speed = distance/time
Speed = 60 miles an hour
Time = 3 hours
We know that Don and Ana are travelling at a constant speed and they are travelling for 3 hours.
Distance = speed × time
Distance = 60 × 3
Distance = 180 miles
Thus, the distance travelled by them in 3 hours is 180 miles.
We know that Don and Ana are travelling on the freeway for the past 3 hours and they are still 650 miles away, therefore,
Total Distance from their destination
= Distance travelled by them in 3 hours + 650 miles
= 180 miles + 650 miles
= 830 miles
Thus, the distance travelled by then is 830 miles.
Now, the distance between them and their destination after 3.7 hours since entering the freeway,
Distance travelled by them = speed x 3.7 = 60 x 3.7 = 222 miles
Distance between them and the destination
= Total Distance from their destination - Distance travelled by them
= 830 miles - 222 miles
= 608 miles
Therefore, they are 608 miles far from their destination.
And, Distance between them and their destination after 2.3 hours since entering the freeway,
Distance travelled by them = speed x 2.3 = 60 x 2.3 = 138 miles
Distance between them and the destination
= Total Distance from their destination - Distance travelled by them
= 830 miles - 138 miles
= 692 miles
Therefore, they are 692 miles far from their destination.
