Answer:
A. 4.40 square units
Step-by-step explanation:
The triangle is isosceles with base angles of 70°. The a.pex angle will be ...
180° -2(70°) = 40°
The area of a triangle can be computed from two sides and the angle between them as ...
A = (1/2)ab·sin(γ)
A = (1/2)(3.7)(3.7)sin(40°) ≈ 4.40 . . . square units
Answer: 5+d
Step-by-step explanation:
More means adding and it doesn't matter which order you put it in in adding.
It is B.
The underlined ≥ symbols a closed circle, and any number bigger than 3 if you multiply it with 4 and solve the equation, your answer would be reasonable
I'll denote the identity function by
. Then for any functions
with inverse
,
![\begin{cases}f\circ\mathrm{Id}=f\\\mathrm{Id}\circ f=f\\f\circ f^{-1}=\mathrm{Id}\end{cases}](https://tex.z-dn.net/?f=%5Cbegin%7Bcases%7Df%5Ccirc%5Cmathrm%7BId%7D%3Df%5C%5C%5Cmathrm%7BId%7D%5Ccirc%20f%3Df%5C%5Cf%5Ccirc%20f%5E%7B-1%7D%3D%5Cmathrm%7BId%7D%5Cend%7Bcases%7D)
One important fact is that composition is associative, meaning for functions
, we have
![(f\circ g)\circ h=f\circ(g\circ h)](https://tex.z-dn.net/?f=%28f%5Ccirc%20g%29%5Ccirc%20h%3Df%5Ccirc%28g%5Ccirc%20h%29)
So given
![h=f\circ g](https://tex.z-dn.net/?f=h%3Df%5Ccirc%20g)
we can compose the functions on either side with
:
![h\circ g^{-1}=(f\circ g)\circ g^{-1}=f\circ(g\circ g^{-1})](https://tex.z-dn.net/?f=h%5Ccirc%20g%5E%7B-1%7D%3D%28f%5Ccirc%20g%29%5Ccirc%20g%5E%7B-1%7D%3Df%5Ccirc%28g%5Ccirc%20g%5E%7B-1%7D%29)
then apply the rules listed above:
![h\circ g^{-1}=f\circ\mathrm{Id}=f](https://tex.z-dn.net/?f=h%5Ccirc%20g%5E%7B-1%7D%3Df%5Ccirc%5Cmathrm%7BId%7D%3Df)
Answer:
The answer would be g 2(7+2)=16
Step-by-step explanation:
You have to contribute and combine like terms and that is how you get your answer
