Answer:
7.51 m
Step-by-step explanation:
The equation matches that required for finding the length of a pendulum that has a period of 5.5 seconds. We can solve for L to find the length.
![5.5=2\pi\sqrt{\dfrac{L}{9.8}}\\\\\dfrac{5.5}{2\pi}=\sqrt{\dfrac{L}{9.8}}\\\\\left(\dfrac{5.5}{2\pi}\right)^2=\dfrac{L}{9.8}\\\\L=74.1125/\pi^2\approx7.509](https://tex.z-dn.net/?f=5.5%3D2%5Cpi%5Csqrt%7B%5Cdfrac%7BL%7D%7B9.8%7D%7D%5C%5C%5C%5C%5Cdfrac%7B5.5%7D%7B2%5Cpi%7D%3D%5Csqrt%7B%5Cdfrac%7BL%7D%7B9.8%7D%7D%5C%5C%5C%5C%5Cleft%28%5Cdfrac%7B5.5%7D%7B2%5Cpi%7D%5Cright%29%5E2%3D%5Cdfrac%7BL%7D%7B9.8%7D%5C%5C%5C%5CL%3D74.1125%2F%5Cpi%5E2%5Capprox7.509)
The length of a pendulum with period 5.5 seconds is about 7.51 meters.

-27.5
Answer:
See below for answers (in bold) and explanations
Step-by-step explanation:
Part A: (h+t)(x) = h(x) + t(x) = (2x-5) + (6x+4) = 2x - 5 + 6x + 4 = 8x - 1
Part B: (h*t)(x) = h(x) * t(x) = (2x-5) * (6x+4) = (2x)(6x) + (2x)(4) + (-5)(6x) + (-5)(4) = 12x² + 8x - 30x - 20 = 12x² - 22x - 20
Part C: h(t(x)) = h(6x + 4) = 2(6x + 4) - 5 = 12x + 8 - 5 = 12x + 3
To find the perimeter of a triangle, you add all the sides.
(2x +1) + (3x+2) + (x+3)
next find all the common variables
2x, 3x, and x
add them together to get
6x
Add 1,2, and 3
6
so your answer is 6x +6
Hope this helps! :)
