Answer:
Option B is correct.
Step-by-step explanation:
Otero translated the phrase "three less than a number" into the expression 3 - x.
I think Otero gave a wrong expression for the phrase.
The true interpretation of the phrase is that if we assume the number as x then three less than a number means x - 3.
Therefore, Otero's expression is inaccurate. Three is being subtracted from a number, so x-3 is what he should have written. (Answer)
Answer:
C = 23.5 in
Step-by-step explanation:
θ = 43°
The length of the side opposite to θ = 16 in.
Hypotenuse = DK
Apply trigonometric ratio, thus:
sin(θ) = opp/hyp
Plug in the values
sin 43 = 16/DK
Multiply both sides by DK
DK*sin 43 = 16
Divide both sides by sin 43
DK = 16/sin 43
DK = 23.5 (nearest tenth of an inch)
The answer to your problem is 54.
X^2 + y^2 can be replaced by r^2 to obtain the polar equation equivalent to x^2 + y^2 = 5. Thus, r^2 = 5, and r = sqrt(5). That's all that's necessary. No matter what the angle is, r will always be sqrt(5).
