There are an infinite number of solutions, so I don't plan to list them all.
I'll list two of them, and then describe how to get all of the rest.
You said that <u>2cos(x) - 1 = 0</u>
Add 1 to each side: 2cos(x) = 1
Divide each side by 2: cos(x) = 1/2
The angles whose cosine is 1/2 are 60 degrees, 300 degrees,
and any multiple of 360 degrees added to either of those.
Answer:
165
Step-by-step explanation:
c = 6 and d = 10
= 5 × 6² = 5 × 36 = 180
- ( 3 d ) = 180 - ( 3 × 10 ) = 180 - 30 = 150
- 3 d ( + 15 ) = 150 + 15 = 165
Answer:
$5 per hour
Step-by-step explanation:
25÷2.5=5
but I don't know if you need to subtract the $5 spent on gas or if its just loss info to throw you off
Answer:
$115.43
Step-by-step explanation:
From the above question:
1 hour of work = $8.55
13.5 hours of work = x
Cross Multiply
x = 13.5 × $8.55
x = $115.425
Approximately to the nearest hundredth = $115.43
If John works 13.5 hours, the amount of money he makes = $115.43
It would be the third option :)
