Answer: A. 12.5

<u>Step-by-step explanation:</u>

$cos\ \theta=\dfrac{adjacent}{hypotenuse}\\\\\\cos\ 28^o=\dfrac{11}{x}\\\\\\\rightarrow\ x=\dfrac{11}{cos\ 28^o}\\\\\\\rightarrow\ x=12.46\\\\\\\rightarrow\ \boxed{x=12.5}\qquad rounded\ to\ the\ nearest\ tenth$

Log₂(6x) - log₂(√x) = 2

log₂[6x/√x] = 2, let's rewrite it in terms of exponent:

(remember : ㏒₂(x) = a (in exponential form) → x = 2ᵃ

6x/√x = 2²

6x/√x = 4, square both sides:
36x²/x = 16 .Simplify:

36x = 16 and x = 16/36 . So x = 4/9

Calculus question plzzzz

miss Akunina [59]

Answer:

Step-by-step explanation:

$f(x)=\frac{1}{\sqrt{x} }\\f'(x)=-\frac{1}{2} x^{-\frac{3}{2}}\\\\f'(4)=-\frac{1}{2} 4^{-\frac{3}{2} }=-\frac{1}{2} \frac{1}{4^\frac{3}{2} } \\=-\frac{1}{2} *\frac{1}{8}=-\frac{1}{16} \\when x=4\\y=f(x)=\frac{1}{\sqrt{4} } =\frac{1}{2} \\\\eq.~ of ~tangent ~line~is\\y=-\frac{1}{2} -\frac{1}{16} (x-4)$
