Answer:
Step-by-step explanation:
The hypothesis needs to explain the certain conditions that need to exist in order for a specific conclusion to take place. Meaning that if these conditions are not present in the scenario, then the conclusion would be different or simply not exist. Based on this info we can say that the hypothesis is "2 lines are perpendicular" while the conclusion is "The lines form 4 right angles"
Simple...
you have:
1.) -8x-16 --->>>
Factor out a -8 -->>
-8(x+2)
2.)9d+15db --->
Factor out 3d -->
3d(3+5b)
3.) 2a-9ax-->>
Factor out -a -->
-1a(9x-2)
Thus, your answer.
Answer:
x = 11 ,
<APT = 6x + 1 ➡ 67°
<PTA = 9x - 24 ➡75°
<PAT = 5x - 17 ➡ 38°
Step-by-step explanation:
(5x - 17) + (9x - 24) + (6x + 1)=180°
20x - 40 = 180°
20x = 180° + 40°
20x = 220°
x = 11
Answer:
about 409.946 Hz
Step-by-step explanation:
The multiplier of frequency is (√(tension multiplier))/(length multiplier), so is ...
(√1.25)/1.2 = (5/12)√5 ≈ 0.931695
So, the longer, tighter string will have the lower frequency of about ...
0.931695×440 Hz ≈ 409.946 Hz
Round 206 to 200 and round 167 to 170
200-170=30
