Which of the following shows the prime factorization of 36 using exponential notation?
O2.3²
O 6²
O 4.9
O 2².3²
(B) 6² shows the prime factorization of 36 using exponential notation.
What is exponential notation?Very large or very small numbers can be written and handled more easily by using exponential notation. A number is typically expressed in exponential notation as a coefficient between one and ten times an integral power of ten, the exponent.For instance, Since the number 7 has been multiplied by itself three times, the exponent, in this case, is three. Since 343 is equal to 7³, we can write it as "7 to the power of 3" or "343 is equal to 7³."So, the prime factorization of 36:
36/6 = 66/6 = 1And we know that: 6 × 6 = 36 ⇒ 6² = 36
Then, the prime factorization of 36 using exponential notation will be 6².
Therefore, (B) 6² shows the prime factorization of 36 using exponential notation.

The domain and range for the relation is [-∞, ∞] and [0,-3], and both of them can be described by interval notation .
Since the graph given to us present a relation or a function, The domain and range of a function are the set of all the inputs and yield a function that can grant separately. The domain and range are vital viewpoints of a function. The domain takes all the conceivable input values from the set of real numbers and the range takes all the yield values of the function. In simple words, the domain is the set of all "x" values and the range is the set of all "y" values in a set of ordered sets and the requested sets are composed as in the form (x, y) or [x,y]
for the given the points are : (0,-3),(1,-3),(2,-3),(3,-3),(4,-3),(5,-3),(-1,-3)(-2,-3),(-3,-3),(-4,-3),(-5,-3)

Consider the function f(x)=cos(0.9x).How much does x have to increase by for 0.9x to increase by 2π?What is the period of f?Consider the function g(x)=sin(5πx).How much does x have to increase by for 5πx to increase by 2π?What is the period of g?
Let Δx be an increase in the variable such that 0.9x increases by 2π. Then:
[tex]\begin{gathered} 0.9(x+\Delta x)-0.9x=2\pi \\ \Rightarrow0.9x+0.9\Delta x-0.9x=2\pi \\ \Rightarrow0.9\Delta x=2\pi \\ \Rightarrow\Delta x=\frac{2\pi}{0.9} \\ \therefore\Delta x=\frac{20\pi}{9} \end{gathered}[/tex]The period of a function f is a quantity T such that for every x, then:
[tex]f(x)=f(x+T)[/tex]The cosine function has a period of 2π over its argument. In this case, we know that:
[tex]f(x)=\cos (0.9x)[/tex]The argument of cosine is 0.9x and we already know that for an increase of 20π/9 in x, there is an increase of 2π in 0.9x. Therefore:
[tex]\begin{gathered} f(x+\frac{20\pi}{9})=\cos (0.9(x+\frac{20\pi}{9})) \\ =\cos (0.9x+0.9\cdot\frac{20\pi}{9}) \\ =\cos (0.9x+2\pi) \\ =\cos (0.9x) \\ =f(x) \end{gathered}[/tex]Then, for every x we know that:

[tex]\frac{20\pi}{9}[/tex]Following a similar process, we can find the period of the function g. Since we know that the period of the sine function is also 2π.

Pigeons once used to be welcome at Trafalgar Square and the public were encouraged to feed them. This gave a good opportunity to estimate the pigeon population in London. At one point 84 pigeons were caught and tagged. Two days later, 120 pigeons were caught in Trafalgar Square and it was found that 3 of the pigeons were tagged. Approximately how many pigeons were there in London?
A total of 201 pigeons are there in London as determined by set theory.
What is Set Theory?
The area of mathematical logic known as set theory examines sets, which are essentially collections of objects.Set theory is an area of mathematics that primarily deals with objects that are pertinent to mathematics as a whole, despite the fact that any form of an object can be gathered into a set.The pigeon caught in the first attempt=84
No. of them tagged=84
⇒Set A=84
Pigeon caught in second attempt =120

Find the zeros of the function ƒ(x) = x2 + 2x – 3.
In order to determine the zeros of this function, the steps are:
1. Assume f(x) = 0. Hence, the equation becomes:
[tex]0=x^2+2x-3[/tex]2. Factor the quadratic function by finding some factors of -3 that sums to the middle term 2.
a. -3 and 1 → -2
b. -1 and 3 → 2
So, the factors of -3 that sums to 2 are -1 and 3.
So, the quadratic equation can be factored into:

The fewest number of miles he can drive each day is option a which is 343.
What is basic division?The mathematical technique used to divide big numbers into more manageable groups or portions in mathematics is called long division. Making a difficulty into manageable, straightforward steps is beneficial. There are remainders, quotients, dividends, and divisors in long divisions. The dividend, which is the big number divided by the divisor in a long division problem, is the problem's large number. The excess amount that cannot be divided is referred to as the residue, and the quotient is the outcome of the division. Compared to multiplication, division is the opposite. When you divide 12 into three equal groups, you get four in each group if three groups of four add up to 12, which they do when you multiply. Determine how many equal groups are created by splitting the population.

Hello there. To solve this question, we'll have to remember some properties about cylinders.
We want to determine the surface area of the following cylinder:
In this case, the surface area comprehends the bottom, the top and the lateral area of the cylinder.
For a cylinder with height h and radius R, it is easy to show that
By redrawing the cylinder as the following figures:
Notice the 2pi * R came from the measure of the circumference of the top and bottom circles.
The area of the circles are given as
[tex]\pi\cdot R^2[/tex]And the area of the rectangle is
[tex]2\pi Rh[/tex]So the surface area of this cylinder is given as
[tex]2\pi R^2+2\pi Rh[/tex]Plugging the values R = h = 1.5 m, we'll get
[tex]2\pi\cdot1.5\cdot(1.5+1.5)=9\pi\approx28.27\text{ m}^2[/tex]In this case, the answer is 9pi and it is contained in the 4th option.
An investigation of a number of automobile accidents revealed the following information:15 accidents involved alcohol and excessive speed27 accidents involved alcohol.13 accidents involved excessive speed but not alcohol22 accidents involved neither alcohol nor excessive speedHow many accidents were investigated? ** note: Let the universal set U be the set of all automobile accidents. Use the information provided to create a Venn diagram containing 2 subsets. Let A be the set of accidents involving alcohol and S be the set of accidents involving excessive speed. **
To solve this type of question we should use the Venn diagram
Let me draw it and show you where we will put each number given
Since there are 15 accidents involved alcohol and excessive speed
Then we should put 15 in the common part of the 2 circles
Since there are 27 accidents involved alcohol
That means 27 = alcohol only + alcohol and excessive speed
Then to find alcohol only we should subtract 15 from 27 to get the number of alcohol only
27 - 15 = 12
Since there are 13 accidents involved excessive speed but not alcohol
That means the excessive speed only is 13
Let us put it in the Venn diagram
Since there are 22 accidents involved neither alcohol nor excessive speed
That means we will put this number outside the circles inside the rectangle
To find the total number of accidents we will add all the numbers in the figure

Equation of line passing through two points (-2,11) and (1,-4) is f(x)=
What is equation of line?y=mx+b is the equation of line where m is the slope and b is the y intercept.
Since slope of line passing through two points (x₁, y₁) and (x₂, y₂)
m=y₂-y₁/x₂-x₁
slope of line passing through two points (-2,11) and (1,-4)
y₂=-4,y₁=11, x₂=1, and x₁=-2
m=-4-11/1-(-2)
m=-15/1+2
m=-15/3
m=-5
Therefore, the slope of the line is -3.
Now use the slope and either of the two points to find the y-intercept.
y=mx+b for (-2, 11)
11=-3(-2)+b
11=6+b
11-6=b
5=b
Hence equation of line will be
y=-3x+5
f(x)=-3x+5
Therefore equation of line passing through two points (-2,11) and (1,-4) is f(x)=-3x+5
