The function form of the given function would be [tex]f(x)=log_b(x)[/tex].
What is a function?
In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
The given function is f(x) = logbx.
So the function form would be the function of x is equal to the logarithmic of x having base b.
so this can be written as
[tex]f(x)=log_b(x)[/tex]
Hence, the function form of the given function would be [tex]f(x)=log_b(x)[/tex].

24 water bottles for $2.95
The cost of 48 water bottles will be $5.9.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that there are 24 water bottles and costs $2.95. The cost of 48 water bottles will be calculated as,
24 water bottles = $2.95
1 water bottle = $2.95 / 24
48 water bottle = ( 2.95 x 48 ) / 24
48 water bottles = $5.9
Hence, the cost will be $5.9.

In circle K shown below, points B, C, D, and E lie on the circle with secants HBD and HCE drawn. Prove:
HExDC=HDxEB
Answer:
By exterior angle theorem, we have;
∠DBE = ∠H + ∠HEB = ∠ECD = ∠H + ∠HDC
∴ ∠H + ∠HEB = ∠H + ∠HDC
By addition property of equality, we have
∠HEB = ∠HDC
∠H = ∠H by reflexive property
∴ ΔHCD ~ ΔHEB by Angle Angle AA similarity postulate
∴ HE/HD = EB/DC, by the definition of similarity
Therefore, by cross multiplication, we have;
HE × DC = EB × HD
Therefore, by commutative property of multiplication, we have;
HE × DC = HD × EB

How many 4 digit multiples can not be divided by 5
Answer:
1800
Step-by-step explanation:
Let us solve this question by Modular Airthmatic.
Let the lowest 4 digit number be X.
X= 1 (mod 5)
X =2 (mod 5)
X=3 (mod 5)
X =4 (mod 5)
X=1+5 t where t is any integer.
1+5 t=2 (mod 5)
5 t=1 (mod 5 )
5 is the Modular Inverse of modulo 5
t=1 (mod 5)
t =1+5 u : u= any integer.
X becomes 1+ 5 (1+5u )=6+25 u
6+25u =3 (mod 5)
25 u= -3 (mod 5)=2 (mod 5)
25 is Modular Inverse of Modulo 5
u=2 (mod 5)
u =2+5 v : v= any integer.
X becomes 6 +25 (2+5 v)=56+125 v .
56 +125 v=4 (mod 5)
125 v=-52 (mod 5)=3 (mod 5)
125 is Modular Inverse of modulo 5
v = 3 (mod 5)
v =3 +5 w where w is any integer.
For lowest 4 digit number, take
w=200
X=1003 : Lowest 4 digit number.
Take w=201
X=208 : Next number.
For 4 digit largest number, take
w=1995
X= 9978 : Largest number.
No. of Numbers =(1995 - 200 )+1=1800 □Ans.

Square root of 16b power four
Answer: 256b
Step-by-step explanation: So, first we need to find the square root of 16b.
That'd be 4b, because a square root is when a number can be divided by a number, such as 4 can go into 16 4 times, and like 5 can go into 25 5 times. So, we got 4b
So, 4 to the power of 4 (ignore the b right now) is the same as 4 x 4 x 4 x 4.
So simplified, that'd be 16 x 4 (64). So, 64 x 4 = 256.
So, I'd be 256b

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations).
Four hemispheres are present in the shaded area. One large hemisphere and three smaller hemispheres each have a radius of 18 cm.
What is the perimeter of the hemisphere's formula?Consequently, the hemisphere's total surface area is 3(pi)R2. A semicircle has a curved line and a straight line that are both equal to the circle's diameter. The curving line is 2R in length while the straight line is (pi)R in length. So, 2R + (pi)R is the semicircle's total perimeter.
The shaded regions' area is calculated as follows:
initially, area of a hemisphere = 2r2 square units
the area of three small hemispheres
(2*3.14*6 r).3 = 226.08 cm2
Area of the larger hemisphere
2*3.14*18^2 = 2034.72cm^2
Total area of the shaded regions = 226.08 + 2034.72 = 2260.8cm^2

Write the explicit formula for the sequence below:
The explicit formula for the sequence -28, -31, -34, -37, ..., is aₙ= -28 -3d.
What is an arithmetic sequence?A series of integers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.
Given:
-28, -31, -34, -37, ...
The general formula of an arithmetic sequence:
aₙ= a₁ + (n)d,
where a₁ is the first term and d is the common difference.
First, we will find the common difference between consecutive terms.
Here,
a₁ = -28
To find the common difference:
a₂ - a₁ = -31 + 28 = -3
a₃ - a₂ = -34 + 31 = 3
a₄ - a₃ = -37 + 34 = 3
Hence, d = -3.
Substitute the values to the formula,
aₙ= a₁ + (n)d,
aₙ= -28 + (-3)d,
aₙ= -28 -3d
Therefore, aₙ= -28 -3d is the required sequence.

For what value of a the system of linear equations Ax 3y a 3 12x ay A has no solutions?
The system of linear equations Ax + 3y = a, 3x + ay = A has no solutions for any value of a.
To determine if the system of linear equations Ax + 3y = a, 3x + ay = A has no solutions for any value of a, we can use the elimination method.
We want to eliminate one of the variables, so let's start by multiplying the first equation by 3 and the second equation by -1.
This gives us:
3Ax + 9y = 3a, -3x - ay = -A.
Now we add the equations together to get:
2Ax + 8y = 3a - A.
Now we can see that the equation is not solvable as there is no value of a that will make the equation true. Therefore, the system of linear equations Ax + 3y = a, 3x + ay = A has no solutions for any value of a.

Identify the graph of x < 2.
Answer:
lower left (already identified)
Step-by-step explanation:
You want the graph showing x < 2.
Line typeThe boundary line of the solution area will be x = 2. Because that line is not included in the space x < 2, the line is dashed. (Eliminates graphs on the right.)
ShadingThe solution space includes values of x that are less than 2. That means they are to the left of the boundary line. Shading will be left of the dashed line. (Eliminates graphs on the top.)
The correct graph of x < 2 is the one at lower left, already highlighted in the image.
