You and a friend are playing a game by tossing two coins. If both coins land on heads,
you win. If both land on tails, your friend wins. Otherwise, nobody wins. The table shows
the possible outcomes.
Is this a fair game?

The function represent the quadratic function is h(x) = 3x(x – 2) – 4, the correct option is D.

Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = ax^2 + bx + c where a, b, c, ∈ R and a ≠ 0.

The function which represnt a quadratic function is;

[tex]\rm h(x) = 3x(x - 2) - 4\\\\ h(x)=3x\times x - 3x \times 2-4\\\\ h(x)=3x^2-6x-4[/tex]

The highest degree of the function is 2 so the function is the quadraic function.

Hence, the function represent the quadratic function is h(x) = 3x(x – 2) – 4.

Answer:

to find the volume of a cylinder formulae is pi r² x Height

Step-by-step explanation:

because to find the volume of any object we have to multiply the area of the base and the height

now as the base of the cylinder is circle we have to fulfill the area of circle with the height of the cylinder

hence

volume

of

the

cylinder = area of circle x height

= pi r² x Height

Answer:

1) 60

2) 80

3) 90

step by step explanation

so sorry

24 minutes.

Let me explain.

The lawn can be any size, but for the purpose of simplicity, let's say it's 240 square meters.

Peter mows 6 square meters per minute if he mows 240 square meters in 40 minutes.

John mows 4 square metres each minute if he mows 240 square metres in 60 minutes.

They'll mow 10 square meters per minute if they work together.

As a result, mowing the entire lawn will take them 24 minutes.

(Note that the location is irrelevant as long as we know how long each man takes to complete the task separately.) The answer would be the same if the field was 1 million hectares in size.)

Answer:

y = -1/5x + 6.4

Step-by-step explanation:

Use the point-slope formula.

y-y₁ = m(x -x₁)

so...

y-7 = -1/5(x - (-3))

y = -1/5x+ 32/5

and you need you can change 32/5 to 6.4

In this part we will just focus on Semicircle with diameter 22 ft.

Given :-

[tex] \\ [/tex]

To find:-

[tex] \\ [/tex]

So first of all let's convert diameter into radius.

we know:-

[tex] \boxed{ \rm{}radius = \frac{Diameter}{2} }[/tex]

So:-

[tex] \\ [/tex]

[tex] \hookrightarrow\sf{}radius = \dfrac{Diameter}{2} [/tex]

[tex] \\ [/tex]

[tex] \hookrightarrow\sf{}radius = \dfrac{22}{2} [/tex]

[tex] \\ [/tex]

[tex] \hookrightarrow\sf{}radius = \dfrac{2 \times 11}{2} [/tex]

[tex] \hookrightarrow\sf{}radius = \dfrac{11}{1} [/tex]

[tex] \\ [/tex]

[tex] \hookrightarrow\sf{}radius = 11[/tex]

[tex] \\ \\ [/tex]

Now let's find area of semicircle!

We know:-

[tex] \boxed{ \rm Area~of~semicircle = \frac{\pi {r}^{2} }{2} }[/tex]

[tex] \\ [/tex]

so:-

[tex] \\ [/tex]

[tex] \dashrightarrow\sf Area~of~semicircle _1= \dfrac{\pi {r}^{2} }{2} [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow\sf Area~of~semicircle _1= \dfrac{22 \times {11}^{2} }{7 \times 2} \\ [/tex]

[tex] \dashrightarrow\bf Area~of~semicircle _1= 190.14 \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \gray{ \bf \dag \frak{Part 2}}[/tex]

So in this part we will find area of other semicircle.

Now as u can see BC isn't given , but AC and AB are given.

So let's find BC:-

[tex] \\ [/tex]

Now we got the diameter, so let's change it into radius.

we know:-

[tex] \boxed{ \rm{}radius = \frac{Diameter}{2} }[/tex]

[tex] \\ [/tex]

so :-

[tex] \hookrightarrow\sf{}radius = \dfrac{Diameter}{2} [/tex]

[tex] \hookrightarrow\sf{}radius = \dfrac{8}{2} [/tex]

[tex] \\ [/tex]

[tex] \hookrightarrow\sf{}radius = \dfrac{2 \times 4}{2} [/tex]

[tex] \\ [/tex]

[tex] \hookrightarrow\sf{}radius = \dfrac{\cancel2 \times 4}{\cancel2} [/tex]

[tex] \\ [/tex]

[tex] \hookrightarrow\sf{}radius = 4[/tex]

[tex] \\ [/tex]

Now let's find area of semicircle!

We know:-

[tex] \boxed{ \rm Area~of~semicircle = \frac{\pi {r}^{2} }{2} }[/tex]

[tex] \\ [/tex]

[tex] \dashrightarrow\sf Area~of~semicircle _2= \dfrac{\pi {r}^{2} }{2} [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow\sf Area~of~semicircle _2= \dfrac{22 \times {4}^{2} }{7 \times 2} \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow\sf Area~of~semicircle _2= \dfrac{\cancel{22} \times {4}^{\cancel2} }{7 \times \cancel2} \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow\sf Area~of~semicircle _2= \dfrac{11\times {4}^{2} }{7} \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow\sf Area~of~semicircle _2= \dfrac{11\times 16}{7} \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow\sf Area~of~semicircle _2= \dfrac{176}{7} \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow\bf Area~of~semicircle _2= 25.14 \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \gray{ \bf \dag \frak{Part 3}}[/tex]

Now Finally in this part we'll add both the areas of these semicircles.

Let :-

[tex] \\ \\ [/tex]

[tex] \sf: \implies Area~of~figure=A_1+A_2 \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \sf: \implies Area~of~figure=190.14+25.14 \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \bf: \implies Area~of~figure=215.28 {ft}^{2} \\ [/tex]

Step-by-step explanation:

5 + y x 3 = 2y - 1

Answer:

-5+(-3)

=-5-3

=-8

Step-by-step explanation:In a problem like this you have to write -3 in parentheses.

Since the + sign is outside the parentheses here, the -3 and + sign are multiplied.

+ saha- multiplication yields -sign.

So there's a -3 coming.

Then -5-3.

Since the sign of this is the same, the two numbers are added. In both - the mark is applied to the answer because there is a mark.

The volume of the rectangular prisms is given by 72 in³, 36 in³, 80 in³ and 54 in³

Volume is the amount of space occupied by a three dimensional shape or object.

The volume of a rectangular prism is given by:

Volume = length * width * height

a) Dimensions: 4 in., 3 in., 6 in.

Volume = 4 * 3 * 6 = 72 in³

b) Dimensions: 6 in., 3 in., 2 in.

Volume = 6 * 3 * 2 = 36 in³

c) Dimensions: 4 in., 5 in., 4 in.

Volume = 4 * 5 * 4 = 80 in³

d) Dimensions: 2 in., 9 in., 3 in.

Volume = 2 * 9 * 3 = 54 in³

The volume of the rectangular prisms is given by 72 in³, 36 in³, 80 in³ and 54 in³

The rate of change or essentially the slope is a numerical value that describes the direction and the steepness of the line.

To find the slope, we just need any two points on the line

       --> Let's pick (0,2) and (2,6)

The slope's equation = [tex]\frac{y2-y1}{x2-x1}[/tex]

Let's plug the known quantities into the equation

     [tex]\frac{y2-y1}{x2-x1}=\frac{6-2}{2-0} =\frac{4}{2} =2[/tex]

Therefore the rate of change is 2 km/trip
