Given the two sets:

we can write the product set of A and B in the following form:

next, we have that the number of elements in A is 2 and the number of elements in B is 3, then, we have:

finally, the equation that involves the numerals of the previous parts is:

where n(A) and n(B) represents the number of elements in A and B respectively.

The symmetry of a quadratic equation is given by the line that passes through its vertex, so in order to find the axis of symmetry we need to find the coordinate of the vertex, which is done below.

Where "a" is the number multiplying the square factor and "b" is the number multiplying the factor that isn't squared. To find these two constants we need to expand the equation given.

We have that a = 1 and b = 4, therefore:

The axis of symmetry for this quadratic equation is x=-2.

According to the given data we have the following function:

Then, f(8)=3(8)-6

f(8)=24-6

f(8)=18

I have 42 dimes in my piggy bank according to the given condition of 66 coins and amount $10.20 and used the system of equation as well as substitution method.

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, also known as a system of equations or an equation system. A group of two or more equations that share the same variables is known as a system of equations. A set of values for a variable that simultaneously satisfy each equation is the solution to a system of equations.

Finding the value of any variable from one equation in terms of another variable is the first step in the substitution method. For instance, if there are two equations, x+y=7 and x-y=8, we can deduce that x=7-y from the first equation. Applying the substitution method begins with this.

Here,

x+y=66    ......(1)

1 dime values 10 cents.

1 quarter values 25 cents.

10x+25y=1020       ........(2)

x=66-y

10(66-y)+25y=1020

660-10y+25y=1020

15y=360

y=360/15

y=24

x=66-24

x=42

I used the system of equations and the substitution method to determine that I have 42 dime coins in my piggy bank in accordance with the requirement of 66 coins totaling $10.20.

To round the nearest hundred the digit in the hundred column and test digit in the tens column.

To round the nearest hundred the digit in the hundred column is rounding digit and the digit in the tens column is test digit.

We find the rounding digit in hundred column is 3. Then we look out the test digit 2 to the right of the 3 in the tens column. Because 2<5 we round down and leave the 3 in the hundred column. Then replace the two rightmost digits with 0's.

The 9,321 rounded to the nearest hundred is 9,300.

Answer:

[tex]\frac{5}{2}[/tex] or 2.5cm

Step-by-step explanation:

Hello! Let's help you with your question here!

Let's start by working out what we know and what we need. So, we know that P is a circle and Q is the shape of a quarter circle with a radius of 20cm. The area of Q is 9 times the area of P and we must find the radius of P.

To start, we're looking for area, so we should at least start looking at the area of a circle, given radius, which is:

[tex]A=\pi r^2[/tex]

Now, we don't necessarily know r (radius) and the area either. However, we can try to use the quarter circle as our guide for the full circle. So, we want to find the area of the quarter circle, we can do that by using this formula!

[tex]A=\frac{1}{4} \pi r^2[/tex]

The reason why we put a [tex]\frac{1}{4}[/tex] at the front of [tex]\pi r^{2}[/tex] is because we're only solving for a quarter of a circle instead of the entire circle.

Now that we have our formula! We can calculate the area of the quarter circle as follows:

[tex]A=\frac{1}{4}\pi 15^2[/tex]

[tex]A=\frac{\pi 15^2}{4}[/tex]   -We combine the fraction [tex]\frac{1}{4}[/tex] into the rest of the equation.

[tex]A=\frac{225\pi }{4}[/tex]   - Evaluating [tex]15^2[/tex]

Now that we have the area of the quarter circle, we can now work on the full circle. What we know is that the area of A is 9 times of B, since we're finding the radius of B, we can essentially plug in the area and solve for the radius of the full circle. That would be as such:

[tex]A=9\pi r^2[/tex]   -We're using the area of circle A to find the radius of B.

[tex]\frac{225\pi }{4} =9\pi r^2[/tex]   - Plugging in the area of the quarter circle.

[tex]\frac{225\pi }{4}/9\pi =\frac{9\pi r^2}{9\pi }[/tex]   - We divide [tex]9\pi[/tex] to get rid of it on the right side.

[tex]\frac{25}{4} =r^2[/tex] - When dividing by [tex]\pi[/tex], the numerator [tex]\pi[/tex] gets cancelled out.

[tex]\sqrt{\frac{25}{4} }=r[/tex]   -We square root to get rid of the squared.

[tex]\frac{5}{2}=r[/tex]    - Square rooted both numerator and denominator.

And there we have it! We finally get a radius of [tex]\frac{5}{2}[/tex] or 2.5cm.

Perimeter = sum of outer lengths

Lenght of the triangle sides = 5ft

perimeter of a semicircle = π d; half = π d / 2

5 ft + 5ft + π r

SOLUTION

The Point of a co-ordinate is always written as

Giving a point

For instance x=2 and y=2, the point will be

If the coordinate of x and y are reversed, the point will remain the same

Hence

the points with the same x- and y-coordinates will give the same location if the coordinate is reversed.

Therefore The Third option is correct (c)

We have a rigth triangle, where we have to find the measure of x.

We can use trigonometric ratios to relate the lengths of the sides and the measure of x.

A horizontal line with evenly spaced numerical increments is referred to as a number line. How the number on the line can be answered depends on the numbers present. The use of the number is determined by the question that it corresponds to, such as when graphing a point.

The visual depiction of numbers, such as fractions, integers, and whole numbers, spread out uniformly along a single horizontal line is known as a number line. A number line can be used as a tool for operations like addition and subtraction as well as comparison and sorting of numbers.

The standard deviation for a total of 200 games is 5.3735.

Let X = number of home runs of this player in 200 games played by him.

p = probability that a this player hits a home run in a single game and this is given to be 0.175.

Where np = Mean of X and √{np(1 - p)} is the standard deviation of X.

Here n = 200 and p = 0.175. So, the standard deviation for a total of 200 games is the standard deviation for a total of X

= √(200 x 0.175 x 0.825) / 2

= 5.3735
