Evaluate the limit of tan 4x/ 4tan3x​
Brut [27]

Answer:

  1/3

Step-by-step explanation:

The ratio is undefined at x=0, so we presume that's where we're interested in the limit. Both numerator and denominator are zero at x=0, so L'Hôpital's rule applies. According to that rule, we replace numerator and denominator with their respective derivatives.

  \displaystyle\lim\limits_{x\to 0}\dfrac{\tan{(4x)}}{4\tan{(3x)}}=\lim\limits_{x\to 0}\dfrac{\tan'{(4x)}}{4\tan'{(3x)}}=\lim\limits_{x\to 0}\dfrac{4\sec{(4x)^2}}{12\sec{(3x)^2}}=\dfrac{4}{12}\\\\\boxed{\lim\limits_{x\to 0}\dfrac{\tan{(4x)}}{4\tan{(3x)}}=\dfrac{1}{3}}

A bat and a ball cost $1.10. The bat is $1 more than the ball. What does the ball cost?
mestny [16]
1.05 is the answer
Write an algebraic equation to solve
a= ball
b= bat
a + b = 1.10
Write out the equation for the ball (a = b + 1)
substitute the equation for the ball into the original equation
(b + 1) + b = 1.10
simplify the equation
2b + 1 = 1.10
Solve the equation
2b + 1 = 1.10
-1. -1
——————-
2b .1
/2 /2 = .05

Plug in your answer into the equation for the ball (a= b + 1)
a= .05 + 1
1.05 is your answer

Rewrite the rational exponent as a radical
Rainbow [258]

\bf a^{\frac{ n}{ m}} \implies  \sqrt[ m]{a^ n}  \qquad \qquad \sqrt[ m]{a^ n}\implies a^{\frac{ n}{ m}}\\\\ -------------------------------\\\\ \left( 5^{\frac{3}{4}} \right)^{\frac{2}{3}}\implies 5^{\frac{3}{4}\cdot \frac{2}{3}}\implies 5^{\frac{2}{4}}\implies 5^{\frac{1}{2}}\implies \sqrt[2]{5^1}\implies \sqrt{5}
