12(4.5+b2)(6)=21

**Answer:**

**2.5in**

**Step-by-step explanation:**

Given parameters;

Base = 4.5inches

Height = 6inches

Area = 21in²

Unknown:

b₂ = ?

Solution:

Formula for finding the area of a trapezium;

A = [tex]\frac{1}{2}[/tex][tex](b_{1} + b_{2} )[/tex] x h

Input the parameters and solve for b₂;

21 = [tex]\frac{1}{2}[/tex][tex](4.5+ b_{2} )[/tex] x 6

21 = 3(4.5 + b₂)

21 = 13.5 + 3b₂

21 - 13.5 = 3b₂

b₂ = **2.5in**

A blouse that is size x in country A is size s(x) in country B, where s(x)x. A blouse that is size x in the country B is size t(x) in country C, where t(x)x. Find a function f(x) that will convert blouse sizes in country A to blouse sizes in country C.

**Answer:**

f(x) = [k(x): x = s(x) = t(x)]

**Step-by-step explanation:**

To make the question clearer, rewrite;

A blouse that is size x in country A is size s(x) in country B.

s(x) = x

A blouse that is size x in country B is size t(x) in country C.

t(x) = x

Find a function f(x) that will convert blouse sizes in country A to blouse sizes in country C.

**f(x) = [k(x): x = s(x) = t(x)]**

Interpretation:

f of x is equal to k of x such that x is equal to s of x which is also equal to t of x.

Where the other blouse sizes are represented by k(x) or as a function of the given size x.

In the expression 3x2y + 4x – 5x2y, are the terms 3x2y and –5x2y like terms? Explain by providing support for your answer.

**Answer:**

yes

**Step-by-step explanation:**

These are like terms because they have the same variables and powers. The coefficients do not need to match for it to be considered a like term.

**Answer:**

Sample Response: Yes, they are like terms because like terms have the same variables raised to the same powers. Both terms contain an x and y variable with the x variable squared.

Select ALL graphs that do NOT represent a function.

**Answer:**

3 and 5

**Step-by-step explanation:**

If you do the vertical line test those ones do not pass. The vertical line test is the test you do to see if it is a function. You draw a vertical line and if that line crosses the graphed line only once it is a function.

Point AAA is at {(1, 5)}(1,5)left parenthesis, 1, comma, 5, right parenthesis and point CCC is at {(-5,-7)}(−5,−7)left parenthesis, minus, 5, comma, minus, 7, right parenthesis. Find the coordinates of point BBB on \overline{AC} AC start overline, A, C, end overline such that ACACA, C is 666 times as long as ABABA, B.

**Answer:**

(0, 3)

**Step-by-step explanation:**

If a point O(x, y) divides a line XY in the ratio n:m with [tex]X\ at\ (x_1,y_1)\ Y\ at\ (x_2,y_2)[/tex], the coordinates of O is:

[tex]x=\frac{n}{n+m} (x_2-x_1)+x_1\\\\y=\frac{n}{n+m} (y_2-y_1)+y_1[/tex]

AC is 6 times AB, this means that point B, divides line AC in the ratio 1:5. Given A at (1,5) and C at (-5, -7)

Let us assume B to be at (x, y), hence:

[tex]x=\frac{1}{1+5}(-5-1)+ 1=\frac{1}{6}(-6)+1 =0\\\\y=\frac{1}{1+5}(-7-5)+5=\frac{1}{6} (-12)+5=3[/tex]

Therefore the location of B is (0, 3)

Is this a function? Explain

**Answer:**

Yes

**Step-by-step explanation:**

The only reason a graph will not be a function is if it doesn't pass the vertical line test. In other words, if you draw a vertical line at any point, it will never pass through more than 1 point.

In that case, that is true, so it must be a function.

Determine the domain, range and whether each table represents a function.

The domain is the possible x values- so it is 1,2,3 .

The range is the possible y values- which are 4,6,8 .

Yes it does represent a function because each element of X is related to ONE element of y.

Hope that helped!

The range is the possible y values- which are 4,6,8 .

Yes it does represent a function because each element of X is related to ONE element of y.

Hope that helped!

==========================================================

Explanation:

The domain is the set of all possible x values. The range is the set of all possible y values.

Since we don't have any repeated x values, we have a function. Any given input x leads to exactly one y output value. Visually plotting the points leads to the graph passing the vertical line test, which shows the relation is a function.

**Answer:**

the mean number of goals scored is 2.5.

the mean number of away goals scored is 1.8.

How many home and away games have been played in total?

**Answer:**

2 games.

**Step-by-step explanation:**

2.5 + 1.8 = 4

4 divided by 2 = 2

**Total** 32 games home and away games have been played.

The **average **of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the **mean**, including simple arithmetic means (adding the numbers together and dividing the result by the **number **of observations), geometric means, and harmonic **means**.

From the **bar **chart :

We can obtain the total number of goals **scored **:

**Home **goals (quarter 1 to quarter 4) :

= (9 + 6 + 8 + 7)

= 30

**Away **goals (quarter 1 to quarter 4) :

= (2 + 7 + 4 + 5)

= 18

Using the relation :

**Mean **goals scored = total goals scored / number of games played

Home **games **:

Mean goals = 2.5

Number of home games played = total goals scored / mean goals

= 30 / 2.5

= 22

Away games :

Mean **goals **= 1.8

Number of **away **games played = 18 / 1.8

= 10

Therefore, number of home and away games **played **in total = 22 + 10 = 32 games

The standard height from the floor to the bull's-eye at which a standard dartboard is hung is 5 feet 8 inches. A standard dartboard is

18 inches in diameter.

Suppose a standard dartboard is hung at standard height so that the bull's-eye is 11 feet from a wall to its left.

Samuel throws a dart at the dartboard that lands at a point 11.5 feet from the left wall and 5.5 feet above the floor.

Does Samuel's dart land on the dartboard?

**Answer:**

Yes, Samuel dart does land on the dart board

**Step-by-step explanation:**

The given parameters are;

The height from the floor to the bulls eye = 5 feet 8 inches

The size of the standard board = 18 inches diameter

The distance of the bulls eye from the wall to the left = 11 feet

The distance the dart Samuel throws land from the left wall = 11.5 feet

The distance above the ground, the dart Samuel throws land = 5.5 feet

Whereby Samuel throws the dart directly at the dartboard, we have;

The location of the bulls eye = (11, 5.67)

The equation of the circle representing the dart board = (x - 11)² + (y - 5.67)² = 0.75² = 0.5625

The unit of the radius is in feet

The position of Samuel's dart is represented by the coordinate, (11.5, 5.5)

Plugging in the coordinates of the position of Samuel's dart into the equation of the circle of the dart board gives;

(11.5 - 11)² + (5.5 - 5.67)² = 0.2789 ≈ 0.528²

Therefore, given that the square of the distance of the position of Samuel's dart is less than the square of the radius of the dart board, we have;

Yes, Samuel dart does land on the dart board.

From the **parameters** given to find out if Samuel's dart landed on the dartboard, we can say that;

*Samuel's dart does not land on the dartboard. *

We are given;

Height from the floor to the bulls eye = 5 ft 8 in = 5.67 ft

**Diameter** of the standard dartboard = 18 in = 1.5 ft

Thus, **radius**; r = 1.5/2 = 0.75 ft

**Distance of the bulls eye** from the wall to the left = 11 ft

**Distance of dart** thrown by Samuel from the left wall = 11.5 ft

**Height of dart** thrown by Samuel above the ground = 5.5 ft

We know that **general equation of a circle** is;

**(x - a)² + (y - b)² = r²**

Since Height from the floor to the bulls eye is 5.67ft,then a = 5.67 ft

And also since Distance of the bulls eye from the wall to the left = 11 ft, then b = 11 ft

Thus;

(x - 11)² + (y - 5.67)² = 0.75²

(x - 11)² + (y - 5.67)² = 0.5625

Now, since he throws a dart at the dartboard that lands at a point 11.5 feet from the left wall and 5.5 feet above the floor. Thus;

r² = (11.5 - 11)² + (5.5 - 5.67)²

**r² = 0.2789**

r² of 0.2789 gotten here is lesser than 0.5625 gotten earlier, we can **conclude** that Samuel's dart does not land on the dart board.
