Can an exponential function be 1?
An exponential function can be equal to 1, but it would have to be a special case.
To determine this:
An exponential function has the form f(x) = ab^x, where a and b are constants. For the function to be equal to 1, the output value of the function must be 1 for all values of x. Therefore, we must have:
[tex]ab^x = 1[/tex]
In order for this equation to be true for all values of x, a and b must be chosen such that:
ab = 1
This means that a and b must be reciprocals of each other. For example, if a = 2, then b = 1/2. In this case, the function [tex]f(x) = 2(1/2)^x[/tex] would be equal to 1 for all values of x.
Another example would be if a = 1 and b = 1. In this case, the function [tex]f(x) = 1(1)^x[/tex] would be equal to 1 for all values of x.
It's important to note that while an exponential function can be equal to 1, it would only be in cases where a and b are reciprocals of each other and not with any other values.

I need help This is hard
To calculate the percent change in David's water intake from Tuesday to Wednesday, we can use the following formula:
percent change = (new value - old value) / old value * 100
In this case, the old value is the number of cups of water David drank on Tuesday (16 cups) and the new value is the number of cups of water he drank on Wednesday (12 cups).
Plugging these values into the formula:
percent change = (12 - 16) / 16 * 100 = -25%
So David's water intake decreased by 25% from Tuesday to Wednesday.
_______________
The original amount in the problem is the amount of water David drank on Tuesday, which is 16 cups.
It was given in the problem as the base value to calculate the percent change in David's water intake from Tuesday to Wednesday.
_____________
The change in David's water intake in this problem is the difference between the amount of water he drank on Tuesday and the amount of water he drank on Wednesday.
On Tuesday, he drank 16 cups of water, and on Wednesday, he drank 12 cups of water.
So the change in David's water intake is:
16 cups - 12 cups = 4 cups
David drank 4 cups less water on Wednesday than on Tuesday.
Step-by-step explanation:
The original amount is 16 cups.
The new amount is 12 cups.
The amount of change is the difference of the two:
16 - 12 = 4 cups.Percent change is the change from the original amount:
4/16*100% = 25%This is a drop or decrease in percent.

How do you solve exponential functions with different bases?
Sometimes we are given exponential equations with different bases on the terms. In order to solve exponential functions with different bases we must know logarithms and how to use them with exponentiation. We can access variables within an exponent in exponential equations with different bases by using logarithms and the power rule of logarithms to get rid of the base and have just the exponent.
What is exponential equationExponential equation is an equation whose power or base number (base) and power contains a variable.
An example of an exponential equation:
32^x-3 = 81^x+5 → the exponential equation with the power contains the variable x
(2x - 5)^x = (2x - 5)^3x-4 → the exponential equation with bases and powers contains the variable x
So, in the exponential equation, it can only be the exponent that contains the variable or it can also be the base and the exponent that contain the variable. This variable is denoted by a letter, it can be from a to z. But, in general, the variable symbol that is often used in questions is the letter x.
The solution to the exponential equation is the set of all x values that satisfy the exponential equation, or we can also call it a set of solutions. So, how to solve the exponential equation varies depending on the form of the equation. The two examples of equations above are two of several forms of existing exponential equations. This means that there are still other forms of exponential equations and each equation has its own way of solving it

Find the exact volume of the solid. Note that the figure is a half-sphere removed from the cylinder. 25mm 15mm
The exact volume of the solid is 963 2/3π cubic cm
How to determine the exact volume of the solid.From the question, we have the following parameters that can be used in our computation:
Shapes = Half-sphere and cylinder
A half-sphere is called a hemisphere, and the volume is calculated as
V₁ = (2/3)πr³
From the given figure (see attachment), we have
r = 14 cm/2
r = 7 cm
Substitute the known values in the above equation, so, we have the following representation
V₁ = (2/3)π * 7³
V₁ = 686/3π
Next, we have the volume of the cylinder to be
V₂ = πr²h
Where
r = 14 cm/2
r = 7 cm
And
h = 22 - 14/2 = 15
So, we have
V₂ = πr²h
Substitute the known values in the above equation, so, we have the following representation
V₂ = π * 7² * 15
V₂ = 735π
The volume of the solid is then calculated as
V = V₁ + V₂
So, we have
V = 686/3π + 735π
Evaluate the sum
V = 963 2/3π
Hence, the volume is 963 2/3π cubic cm

How do you dilate a linear function?
If the parent graph is made steeper or less steep (y = ½ x), the transformation is called a dilation.
And if the parent graph is changed so that it falls to the right instead of rising to the right (y = -x), the transformation is called a reflection.
If x is replaced by x/A in a formula and A>1, then the effect on the graph is to expand it by a factor of A in the x-direction (away from the y-axis). If A is between 0 and 1 then the effect on the graph is to contract by a factor of 1/A (towards the y-axis). We use the word "dilate'' to mean expand or contract.
f y is replaced by y/B in a formula and B>0, then the effect on the graph is to dilate it by a factor of B in the vertical direction. As before, this is an expansion or contraction depending on whether B is larger or smaller than one. Note that if we have a function y=f(x), replacing y by y/B is equivalent to multiplying the function on the right by B: y=Bf(x). The effect on the graph is to expand the picture away from the x-axis by a factor of B if B>1, to contract it toward the x-axis by a factor of 1/B if 0<B<1, and to dilate by |B| and then flip about the x-axis if B is negative.
When dilating a line, check if the center is on the line. If the center lines on the line, the line remains the same.
The line whose equation is y = x + 3 is dilated by a scale factor of 2 centered at the origin. Write the equation of the line after the dilation.

the term to term rule for a sequence is to subtract 3 each time. the 13th term is 25. what is the 15th term
The required 15th term will be 19 given rules for a sequence.
What is an arithmetic sequence?An arithmetic sequence is defined as an arrangement of numbers that is in a particular order.
Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The term-to-term rule for the sequence is to subtract 3 each time. If the 13th term is 25, we can use this rule to determine the 15th term.
We know that the 13th term is 25 and the rule is to subtract 3 each time, so:
13th term: 25
14th term: 25 - 3 = 22
15th term: 22 - 3 = 19
Therefore, the 15th term will be 19.

How to solve variables in a line segment?The length of the lines are indicated on the diagram. The line below is bisected into two equal halves.
Therefore, let's find the value of x in the line segments.
5x + 8 = 21x
5x - 21x = -8
-16x = -8
divide both sides of the equation by -16
x = -8 / -16
x = 1 / 2
Therefore, let's find the value of y in the line segments.
20y - 2 = 17y + 3
20y - 17y = 3 + 2
3y = 5
divide both sides of the equation by 3
y = 5 / 3
y = 5 / 3 = 1.66666666667 = 1.7
