The mod
Anna007 [38]

Answer:

Step-by-step explanation:

base = 784 sq in²  28 in tall pyramid

each side of the square base = √784   also equals 28

using the Pythagorean theorem the length of each side of the pyramid from the base to the point is

(side/2)² + height² =( length of the pyramid face)²

(28/2)² + 28²  = 196 + 784  = 980 =  (face length)²

face length = √980    =  31.3

area of the pyramid = 4 sides × area of each face + the area of the base

    =   4×[(1/2)(base)(face length)] + side²

    =   4(1/2)(28)(31.3) + 784

    =   2537 sq in²     Not in the solution set

Which craftworld should I choose to colect for Warhammer 9th edition:
g100num [7]

Answer:

Ulthwé was caught in the pull of the Eye of Terror, where the Immaterium intersects with realspace. It is a breeding ground for Chaos and a gateway into the Warp. Due to this baleful proximity to the Eye, Ulthwé must be on constant high alert in case of attacks by the Forces of Chaos. Constant risk and warfare has hardened this Craftworld's citizens to hardship. Due to the lack of Aspect Warriors on the Craftworld, Ulthwé maintains a standing militia known as the Black Guardians, who are more skilled and better-trained than the Guardians of other Craftworlds.Step-by-step explanation:

What is the value of arcsin(0) in degrees?<br><br> Enter your answer in the box.
melisa1 [442]

Answer:

Therefore,

The value of arcsin(0) is 0° or 180° or 360° or 540° or n×180° so on.

Step-by-step explanation:

To Find:

arcsin(0) in degrees =?

Solution:

' arcsin ' a mathematical function that is the inverse of the sine function.

Therefore, arcsin (x) is called the inverse sine function.

It is the angle whose sine is the number x.

So here we require angle in degree for which the Sine is '0'.

It is also written as

\sin^{-1}x

We Know that

\sin 0\°=0\\or\\\sin 180\°=0

Therefore,

\arcsin (0) = 0\°\\or\\\arcsin (0) = 180\°

Also integer multiples of 180° will have

\arcsin (0)=n\times 180\°

Where n = integer

Therefore for '0' we can have 2×180° , 3×180° , 4×180°....and so on i.e 360° , 540° and so on

Therefore,

The value of arcsin(0) is 0° or 180° or 360° or 540° or n×180° so on.

What is the equation, in factored form, of the quadratic functions shown in the graph?
mina [271]

Answer:

(x+3)(x-2)

Step-by-step explanation:

We can immediately see that there are roots at x = -3, and x = 2.

Because the website gives us that this in the form of (x + _) (x - _), our anwser is (x+3)(x-2)

oops I just saw your comment. Too late i guess...
