Answer:
h(x) = -2|x+2| + 2
Step-by-step explanation:
let me know if you want an explanation :))
6
6 * 0.7 = 4.2
4.2 * 0.7 = 2.94
2.94 * 0.7 = 2.058
2.058 * 0.7 = 1.4406
1.4406 * 0.7 = 1.00842
4.2 + 4.2 + 2.94 + 2.94 + 2.058 + 2.058 + 1.4406 + 1.4406 =
Answer:
y=60 x=16
Step-by-step explanation:
the triangles are identical so 92+y=3y-28 so solve that for y:
-y +28
120=2y . /2 /2
60 = y so y=60
and 6x+2=3x+50 and solve that for x: which gets x = 16
Then are you supposed to plug it in to the numerical equvilant to the angles and sides becuase if so: B and E is 152, AC and DF are 98
Hope this helps and brainliest would be greatly appreciated! Thanks!
Answer:
reeee
Step-by-step explanation:
Formula is: h = vi · t + 1/2 g · t²
For the final position ( on the ground ): h = - 255 ft
vi = - 21 ft/s, g = -9.81 m/s² = - 32.174 ft/s²
- 255 = - 21 t - 1/2 · 32.174 t²
16.087 t² + 21 t - 255 = 0
t 1/2 = ( - 21 +/- √ (441 + 16,408.74 ))/ 32.174 =
= ( -21+/- 129.8 ) / 32.174 = 108.8 / 32.174 = 3.38 s
Answer: The ball hits the ground after 3.38 s.
