➷ You can use this formula:

area = 1/2ab * sinC

Substitute the values in:

area = 1/2(17)(15) * sin(35)

Solve:

area = 73.13099

This can be rounded to give the answer of:

73.1 m^2

The midpoint of a line segment is (−3,2). One endpoint of the line segment is (4,−7).What are the coordinates of the other endpoint of the line segment?

Answers

The coordinates of the other endpoint of the line segment are $Y(x,y) = (-10, 11)$ .

Vectorially speaking, the midpoint of a line segment is determined by the following expression:

$M(x,y) = (1)/(2)\cdot X(x,y) + (1)/(2)\cdot Y(x,y)$ (1)

Where:

$M(x,y)$ - Midpoint.
$X(x,y)$ , $Y(x,y)$ - Endpoints of the line segment.

If we know that $M(x,y) = (-3, 2)$ and $X(x,y) = (4, -7)$ , then the coordinates of the other endpoint is:

$(1)/(2)\cdot Y(x,y) = M(x,y) -(1)/(2)\cdot X(x,y)$

$Y(x,y) = 2\cdot M(x,y) -X(x,y)$

$Y(x,y) = 2\cdot (-3,2)-(4,-7)$

$Y(x,y) = (-6, 4) - (4, -7)$

$Y(x,y) = (-10, 11)$

The coordinates of the other endpoint of the line segment are $Y(x,y) = (-10, 11)$ .

Answer:

Rectangular prism

I chose a box of cereal.

Part 1)List the dimensions of your box. Be sure to include the units (in, cm, ft, etc.).

Length: 20 cm

Width: 8 cm

Height: 32 cm

Part 2).

Describe the shape of the cross-section when the box is cut parallel to the base.

The shape of the cross-section would be a rectangle in dimensions.

20 cm x 8 cm

Part 3)

What is the surface area of the box?

surface area=2*area of the base + perimeter of the base*height

area of the base=20*8=160 cm²

perimeter of the base=2*[20+8]-----> 56 cm

height=32 cm

surface area=2*160+56*32------> 2,112 cm²

the answer part 3) is

2,112 cm²

Part 4)

What is the surface area of the box if it is scaled up by a factor of 10?

we know that

surface area of the larger box =[scale factor]²*surface area original box

scale factor=10

surface area original box=2,112 cm²

surface area of the larger box=10²*2,112-----> 211,200 cm²

the answer part 4) is

211,200 cm²

Part 5)

What is the volume of the box?

volume of the box = L*W*H 20*8*32-5,120 cm³

the answer Part 5) is

5,120 cm³

Part 6)

What is the volume of the box if it is scaled down by a factor of 1/10?

we know that

the volume of the smaller box =[scale factor]³volume original box

scale factor=1/10

volume original box=5,120 cm³

volume of the smaller box =[1/10]³*5,120 5.12 cm³

the answer part 6) is

5.12 cm³

The length is 6 in., the width is 2 in., and the height is 16 in.

Hello from MrBillDoesMath!

Answer:

88 in^3

Discussion:

The volume of a cone of height h and base radius r is

Pi * R^2 * (h/3)

But Pi * r^2 ( = 30) is the area of the base so the volume is:

(30) * (8.8)/3 =

(30/3) ( 8.8) =

10 * 8.8 =

88 in^3
