Step-by-step explanation:
tan Ф = opposite side divided by the adjacent side
tan Ф = opp/adj in your problem Ф is x
tan x = 4/9
x = arctan (4/9) on your calculator arctan is might look like inverse tan
or you might have to use the 2nd (second) button and then tan
x = inverse tan (0.44444 repeating) try it on your own calculator
= 23.962488974578183 rounds up to 24.0
= 24.0
Answer:
x ∈ R, x ≠ 9
Step-by-step explanation:
Given
f(x) = ![\frac{1}{x-9}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bx-9%7D)
The denominator of f(x) cannot be zero as this would make f(x) undefined.
To find the value that x cannot be, equate the denominator to zero and solve for x
x - 9 = 0 ⇒ x = 9 ← excluded value
Thus the domain is x ∈ R, x ≠ 9
Answer:
The number -5 is a real number is true.
Find 6% of 890 and then add it to 890. So,
890x0.06=53.4
890+53.4=$943.50
