Step-by-step explanation:

the coordinates of the midpoint are the average of the coordinates of the endpoints.

let coordinates of C = (x, y ) , then with A = (- 1, 2 ) calculate the average and equate to the coordinates of B (3, 2 )

[tex]\frac{x-1}{2}[/tex] = 3 ( multiply both sides by 2 to clear the fraction )

x - 1 = 6 ( add 1 to both sides )

x = 7

and

[tex]\frac{y+2}{2}[/tex] = 2 ( multiply both sides by 2 )

y + 2 = 4 ( subtract 2 from both sides )

y = 2

coordinates of C = (7, 2 )

The remainder of the expression x/(x + 1) is a negative one. Then the correct option is D.

The division means the separation of something into different parts, sharing of something among different people, places, etc.

The expression is given below.

[tex]\rm \rightarrow \dfrac{x}{x+1}[/tex]

Add and subtract 1 in the numerator, then we have

[tex]\rm \rightarrow \dfrac{x+1-1}{x+1}\\\rm \rightarrow 1 -\dfrac{1}{x+1}[/tex]

Then the remainder will be a negative one.

Answer:

D) -1

Step-by-step explanation:

point-slope form: y-y₁=m(x-x₁)

==========

slope-intercept form: y = mx + b

==========

Point slope is written as y - y1 = m(x -x1)

Where x1 and y1 are the given point and m is the slope:

point slope :

Y-2 = 7(x-1)

slope intercept is written as y = Mx + b where m is the slope and b is the y intercept:

musing the slope you have y = 7x + b

Now replace y and x with the given point to solve for b:

2 = 7(1) = b

2 = 7 + b

Subtract 7 from both sides to get b = -5

now replace b in the equation to get:

Y = 7x-5

Part I: Recalling the "Volume of cone" formula

Given:

Formula (Volume of cone):

[tex]\text{Volume of cone:} \ \dfrac{1}{3} \times \pi \times r^{2} \times h[/tex]

[Where r and h are the radius and the height respectively.]

Part II: Determining the volume of the cone

Substitute their values into the formula to determine the volume of the cone.

    [tex]\implies \text{Volume of cone:} \ \dfrac{1}{3} \times \pi \times (9)^{2} \times (10)[/tex]

∴ Let π be 3.14 ∴

    [tex]\implies\text{Volume of cone:} \ \dfrac{1}{3} \times 3.14 \times (9)^{2} \times (10)[/tex]

Simplify the expression to determine the volume.

    [tex]\implies\text{Volume of cone:} \ \dfrac{1}{3} \times 3.14 \times 81 \times 10[/tex]

    [tex]\implies\text{Volume of cone:} \ 3.14 \times 27 \times 10[/tex]

    [tex]\implies\text{Volume of cone:} \ 31.4 \times 27[/tex]

    [tex]\implies\text{Volume of cone} = 847.8 \ \text{yd}^{3} = \boxed{847.80 \ \text{yd}^{3}} \ \ \ \ \ \ \ \ (\text{Nearest hundredth)}[/tex]

Let the vertices of the prism be A, B, C, D, E, F, G, and H. (Refer to image).

From the image, we can tell that the faces of the prism are:

ABFG    HDCE     FBCE     GADH     GFEH    ABCD

Surface area formula:

[tex]\text{Surface area = Sum of the area of it's faces}[/tex]

The faces are ABFG, HDCE, FBCE, GADH, GFEH, and ABCD (Previous Part)

[tex]\implies \text{SA = A(ABFG) + A(HDCE) + A(FBCE) + A(GADH) + A(GFEH) + A(ABCD)}[/tex]

If we look at the prism carefully, we can tell that:

ABFG = DCEH

GADH = FBCE

GFEH = ABCD

Therefore, the new equation is:

[tex]\implies \text{SA = 2[A(ABFG)] + 2[A(GADH)] + 2[A(GFEH)]}[/tex]

If we look carefully, we can see that GADH and ABFG are rectangles. Therefore, their areas will be length multiplied by width. Now, substitute the dimensions of the rectangles in the surface area.

[tex]\implies \text{SA} = 2[4 \times 4] + 2[2.5 \times 4] + \text{2[A(GFEH)]}[/tex]

The area of a parallelogram is the base multiplied by the height.

[tex]\implies \text{SA}= 2[4 \times 4] + 2[2.5 \times4] + 2[4 \times 2]}[/tex]

Finally, simplify the equation to determine the surface area.

[tex]\implies \text{SA} = 2[16] + 2[10] + 2[8][/tex]

[tex]\implies \text{SA} = 32 + 20 + 16[/tex]

[tex]\implies \boxed{\text{SA = 68 m}^{2} }[/tex]

Let's first find the area of the rectangle/rectangle,

we can do this by combining their lengths as a whole

or

we can individually find their area.

Let's find the area of the individual shapes, upper rectangle;

(using the formula)

A = l x w

Where 'l' represents the length and 'w' stands for the width.

Plug in what you know:-

A = 27(24)

A = 648 square feet is the area of the upper rectangle.

Now, the lower rectangle:

A = l x w

Plug in what you know:-

A = 27(32)

A = 864 square feet is the area of the lower rectangle.

Now we find the area of the triangle beside;

(using the formula)

A = BH x 1/2

Where 'B' represents the base, 'H' the height, and 1/2 means to simply divide the product of those two lengths(base x height) by 2.

Plug in what you know:

A = BH x 1/2

A = 18(32) x 1/2

A = 576 x 1/2

A = 576/2

A = 288 square feet is the area of the triangle beside.

Add up all the areas we've gathered so far:

648 + 864 + 288

= 1,800 square feet is the area of the patio
