The answer is 43.01, because it is a 5-sided shape like a pentagon. Thus using the formula of to find the area of a pentagon, you will find the area of the shape.
Answer: all of them they are negitive numbers
Step-by-step explanation:
The first option is the correct quadratic formula
Answer:
The expression which is equivalent to (k ° h)(x) is
⇒ 2nd answer
Step-by-step explanation:
* Lets explain the meaning of the composition of functions
- Composition of functions is when one function is inside of an another
function
# If g(x) and h(x) are two functions, then (g ° h)(x) means h(x) is inside
g(x) and (h ° g)(x) means g(x) is inside h(x)
* Now lets solve the problem
∵ h(x) = 5 + x
∵ k(x) = 1/x
- We need to find (k ° h)(x), that means put h(x) inside k(x)
* Lets replace the x of k by the h(x)
∵ k(x) = ![\frac{1}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bx%7D)
∵ h(x) = 5 + x
- Replace the x of k by 5 + x
∴ k(5 + x) = ![\frac{1}{5 + x}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%20%2B%20x%7D)
∴ The expression which is equivalent to (k ° h)(x) is
Answer:
![3\sqrt5](https://tex.z-dn.net/?f=3%5Csqrt5)
Step-by-step explanation:
The pythagorean theorem is
where c is the hypotenuse.
so, ![3^2+6^2=c^2](https://tex.z-dn.net/?f=3%5E2%2B6%5E2%3Dc%5E2)
9 + 36 = 45
![\sqrt45=\sqrt{c^2}](https://tex.z-dn.net/?f=%5Csqrt45%3D%5Csqrt%7Bc%5E2%7D)
c = ![3\sqrt5](https://tex.z-dn.net/?f=3%5Csqrt5)
