Cos (Ф) = 0.9123
To calculate Ф, we have to find the arcos (0.9123) ≈ cos⁻¹ (0.9123)
cos⁻¹(0.9123) = Ф
cos⁻¹ (0.9123) = 24°.175
Ф = 24°.175
10,000+5,000+400+9
there is one and the other you just put in word form
You need a number so that 2x = -6 that is -3 . Now square this number. This gives +9
Answer is 9
Step-by-step explanation:
You could add (-1.07 + 2.971) to get (1.901)
Then do (1.901 - 4.3) to get a negative number; (-2.399)
I would double check this all with a calculator
