Realize the tangent function has a period of 180°, so when your calculator (or memory) tells you
.. θ = arctan(-1)
.. θ = -45°
you can translate that value into the desired range by adding multiples of 180° to get the two solutions ...
.. θ = 135°
.. θ = 315°
Answer:
Pretty Sure all except D. and E. are true
Step-by-step explanation:
The text states the ship reaches 236 dt above sea level proving A. true
The ship also reaches -74 ft below sea level meaning it goes 74 ft undersater proving B.
The 74 ft plus the 236 ft show that the ship's full size is more than 236 alone proving C. correct
and proving D. and E. false as well
Answer:
Step-by-step explanation:
combine like terms (6n-4n)=(5-15)
2n=-20
n=20/2
n=10
Answer:
Step-by-step explanation:
(a) 1.56×10^4 = 1.56×10000 = 15,600
(b) There are 3600 seconds in an hour, so Andrew's time was
15600 s/(3600 s/h) = 13/3 h = 4 1/3 h
1/3 hour is 20 minutes, so Evelyn's time of 4:16 is shorter than Andrew's time of 4:20.
Answer:
Budget annual payroll = $168,480
Step-by-step explanation:
Given:
Expect sales per week = $9,000
Revenue over sales = 36% = 0.36
Find:
Budget annual payroll = ?
Computation:
Assume number of week per year = 52
⇒ Budget annual payroll = Expect sales per week × Number of week per year × Revenue over sales
⇒ Budget annual payroll = $9,000 × 52 × 0.36
⇒ Budget annual payroll = $168,480
