We are looking for the approximate solution of
![-2x+4=(0.25)^x](https://tex.z-dn.net/?f=-2x%2B4%3D%280.25%29%5Ex)
, that is, we are looking for the solution of the equation f(x)=g(x).
The solution of this equation are represented by the intersecting points (x, y) of the graphs of these functions, because the intersecting points (x, y) are such that
y=f(x), but also y=g(x).
From the graph, we can see that there are two solutions, one is at approximately x=2, and the other is approximately -1.4.
Answer: -1.4, 2.
| T - 55 | < = 10
-10 < = T - 55 < = 10
-10 + 55 < = T - 55 + 55 < = 10 + 55
45 < = T < = 65
the average temp ranges are between (and including) 45 degrees to 65 degrees
Answer:
(C.)
Step-by-step explanation:
![a^{2} +b^{2} =c^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2Bb%5E%7B2%7D%20%3Dc%5E%7B2%7D)
![(2^{2} )+(3^{2})=x^{2}](https://tex.z-dn.net/?f=%282%5E%7B2%7D%20%29%2B%283%5E%7B2%7D%29%3Dx%5E%7B2%7D)
![4+9=x^{2}](https://tex.z-dn.net/?f=4%2B9%3Dx%5E%7B2%7D)
![13=x^{2}](https://tex.z-dn.net/?f=13%3Dx%5E%7B2%7D)
![\sqrt{13} =\sqrt{x^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B13%7D%20%3D%5Csqrt%7Bx%5E%7B2%7D%20%7D)
![x=\sqrt{13}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B13%7D)
Ratio of shadow to object's size = 2/7
Then, size of tree would be: 7/2 * 28 = 7 * 14 = 98 feet
So, your final answer is 98 feet
Hope this helps!
Answer: y^16/x^9
Step-by-step explanation:
(x^-2(y^4))^3/x^3y^4
(x^-2y^4)^3/x^3 * y^4
x^-6y^12/x^3 * y^4
y^12/x^9 * y^4
y^16/x^9
