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.

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

BRAINLIEST + POINTS<br><br> Can someone explain why is B correct? Please show your work

Viefleur [7K]

Answer:

B. $1680

Step-by-step explanation:

Note the simple interest formula:

Interest = (Principal)(rate)(time)

Principal = $6000

Rate = 7% = 0.07

Time = 4

Plug in the corresponding numbers for the corresponding variables.

I = (P)(R)(T)

I = (6000)(0.07)(4)

Multiply.

I = (24000)(0.07)

I = 1680

Interest is $1680.

Which of the following are the most likely factors of the function graphed above?

alexandr402 [8]

Answer: OPTION C.

Step-by-step explanation:

You can observe in the graph that the solutions of the Quadratic function are:

$x=-5\ or\ x=1$

By definition, the parabola intersects the x-axis when the value of "y" is zero, applying the Addition property of Equality:

$x+5=-5+5\\\\x+5=0$

Applying the Subtraction property of Equality:

$x-1=1-1\\\\x-1=0$

The Zero Product property states that:

If $a*b = 0$ then $a = 0\ or \ b = 0$

Then, you know that:

$(x-1)(x+5)=0$

Therefore the most likely factors of the function graphed above are:

$(x-1)(x+5)$

Help!! Gotta finish 2 units in 4 days!!

Step2247 [10]

Answer:

$\large \boxed{\sf \ \ g(x)=3|x| \ \ }$

Step-by-step explanation:

Hello,

Let's follow the instructions !

Step 1

g(x)=k*f(x)=k*|x|

We know that the point (2,6) is on the graph so 6=g(2) meaning:

6=k*|2|=k*2

*** divide by 2 both sides ***

k = 6/2 = 3

Step 2

g(x)=3*|x|

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

The lines represented by the equations y=x+5 and 2y-2x=10 are

ioda

The equations representing the lines, y=x+5 and 2y-2x=10, have the same slope, therefore the lines are parallel.

<em><u>Recall:</u></em>

Two lines that are parallel will have the same slope value.

Two lines that are perpendicular to each other will have slopes that are negative reciprocal of each other.

Equation representing a line in slope-intercept form is: y = mx + b, where m is the slope.

<em><u>Given:</u></em>

y = x + 5

2y - 2x = 10

The slope of y = x + 5 is 1.

Rewrite 2y - 2x = 10 in slope-intercept form to determine its slope.

2y - 2x = 10

2y = 2x + 10

Divide both sides by 2

y = x + 5

Thus, the slope of y = x + 5 (2y - 2x = 10) is also 1.

The equations representing the lines, y=x+5 and 2y-2x=10, have the same slope, therefore the lines are parallel.
