(3/4x - 1) + (3/4x - 2)
6/4x -1 -2
6/4x - 3
3/2x -3
3-6x/2x
Answer: 3-6x/2x
Answer 96in2
Step-by-step explanation:
formula to find area = base x height
substitute the values
= 10 x 9
= 90 cm2
To solve this proble you must apply the proccedure shown below:
1. You have that:
- <span>David is standing 5000 feet away from the base of a cell phone tower. and the angel of elevation from his eyes to the top of the tower is 78 degrees.
- David’s eyes are 6 feet.
2. Therefore, you have:
Tan</span>α=opposite/adjacent
Tanα=x/5000
x=(5000)(Tan(78°))
x=23,523.15 feet
3. Then, you have that the height of the tower is:
h=6 feet+23,523.15 feet
h=23,529.15 feet
The answer is:23,529.15 feet
144 if a full circle makes 360 and you subtract 72 from it is 288 then you divide it by 2 you get 144. Don’t know if i’m right double check incase!
Answer:
![g\left(x\right)=-\sqrt{x+3}+8](https://tex.z-dn.net/?f=g%5Cleft%28x%5Cright%29%3D-%5Csqrt%7Bx%2B3%7D%2B8)
Step-by-step explanation:
Given function is
.
Now let's find it's range.
we know that square root function always gives positive output then:
![\sqrt{x-3}\ge0](https://tex.z-dn.net/?f=%5Csqrt%7Bx-3%7D%5Cge0)
![-2\sqrt{x-3}\le-2\left(0\right)](https://tex.z-dn.net/?f=-2%5Csqrt%7Bx-3%7D%5Cle-2%5Cleft%280%5Cright%29)
![-2\sqrt{x-3}\le0](https://tex.z-dn.net/?f=-2%5Csqrt%7Bx-3%7D%5Cle0)
![-2\sqrt{x-3}+8\le0+8](https://tex.z-dn.net/?f=-2%5Csqrt%7Bx-3%7D%2B8%5Cle0%2B8)
![-2\sqrt{x-3}+8\le 8](https://tex.z-dn.net/?f=-2%5Csqrt%7Bx-3%7D%2B8%5Cle%208)
![f(x) \le 8](https://tex.z-dn.net/?f=f%28x%29%20%5Cle%208)
Hence range of the function is
.
we can repeat same process to find the range of all the given choices.
we will find that only 3rd choice has same range.
Hence final answer is ![g\left(x\right)=-\sqrt{x+3}+8](https://tex.z-dn.net/?f=g%5Cleft%28x%5Cright%29%3D-%5Csqrt%7Bx%2B3%7D%2B8)
