Answer:

Answer of given Statement is False.

Step-by-step explanation:

We know that

Polyhedron is a Solid figure entirely made up up of polygons.

for example: cube, cuboid, soccer ball, etc

Prism is a solid figure with two equal bases.

for example: Cube. Cuboid, Cylinder, etc

Pyramid is a polyhedron with a base and an Apex at top.

for example: Cone, triangle based pyramid, etc

Since, Cylinder is a Prism but it is not a polyhedron. Also Cone is pyramid but it is not a polyhedron,

Therefore, Answer of given Statement is False.

For the answer to the question above,
1 + nx + [n(n-1)/(2-factorial)](x)^2 + [n(n-1)(n-2)/3-factorial] (x)^3

1 + nx + [n(n-1)/(2 x 1)](x)^2 + [n(n-1)(n-2)/3 x 2 x 1] (x)^3 

1 + nx + [n(n-1)/2](x)^2 + [n(n-1)(n-2)/6] (x)^3 

1 + 9x + 36x^2 + 84x^3 

In my experience, up to the x^3 is often adequate to approximate a route. 

(1+x) = 0.98 

x = 0.98 - 1 = -0.02 

Substituting: 

1 + 9(-0.02) + 36(-0.02)^2 + 84(-0.02)^3 

approximation = 0.834 

Checking the real value in your calculator: 

(0.98)^9 = 0.834 

So you have approximated correctly. 

If you want to know how accurate your approximation is, write out the result of each in full: 

1 + 9(-0.02) + 36(-0.02)^2 + 84(-0.02)^3 = 0.833728 

 (0.98)^9 = 0.8337477621 

So it is correct to 4

Find the perimeter and the area of jacobs pool shown in the diagram below be sure to show all your work

Ksenya-84 [330]

Answer: Perimeter- 88m Area- 207sqm

Step-by-step explanation: To find the perimeter, you have to sort of split the shape into simple boxes. To find the line at the bottom, you have to add 18+11 because you can see that they match the line in the bottom. 18+11=29. You then have to find the P of the left. With the same method, you do 6+9, which equals 15. You add all of the sides together to get 88m. To find Area, you split the boxes into 2 smaller boxes. you then do 18x6 to get 108 for the top box. And 11x9 which equals 99. You add them together to get the area, 207! Hope that makes sense!!!

The function f(x) represents the time it takes an airplane to travel east. The function g(x) represents the time it takes an air

tensa zangetsu [6.8K]

The total time taken for round trip will be: (f+g)(x) = 14x+11

Step-by-step explanation:

Given

$f(x) = 4x+13\\g(x) = 10x-2$

In order to find the round-trip time, we have to add both functions to represent the time taken to travel east and the time taken to travel to west.

$(f+g)(x) = f(x)+g(x)\\= (4x+13)+(10x-2)\\=4x+13+10x-2\\=4x+10x+13-2\\=14x+11$

Hence,

The total time taken for round trip will be: (f+g)(x) = 14x+11
