simplify the following using L'Hôpital's Rule:
[tex]\displaystyle\lim_{x\to 2}\frac{x^2+x-6}{x^2-4}[/tex]
[tex]\text{note:explanation is a must}[/tex]
Answer:
[tex] \displaystyle \: \frac{5}{4} [/tex]
Step-by-step explanation:
we are given a expression
we are said to solve it using L'Hôpital's Rule
recall, L'Hôpital's Rule:
[tex] \displaystyle \lim _{x \to \: c}( \frac{f(x)}{g(x)} ) = \lim _{x \to \: c} \frac{f ^{'}(x) }{ {g}^{'}(x) } [/tex]
it is to say the ' means derivative
our given expression:
[tex]\displaystyle\lim_{ x\to 2}\frac{x^2+x-6}{x^2-4}[/tex]
let's apply L'Hôpital's Rule
[tex]\displaystyle\lim_{ x\to 2}\frac{ \dfrac{d}{dx} (x^2+x-6)}{ \dfrac{d}{dx} (x^2-4)}[/tex]
some formulas of derivative
[tex] \displaystyle \: \frac{d}{dx} {x}^{n} = {nx}^{n - 1} [/tex]
[tex] \displaystyle \: \frac{d}{dx} {x}^{} = 1[/tex]
[tex] \displaystyle \: \frac{d}{dx} {c}^{} = 0[/tex]
[tex] \sf \displaystyle \: \frac{d}{dx} {f}^{} (x) + {g}^{}(x) = {f}^{'} (x) + {g}^{'}(x)[/tex]
use sum derivative formula to simplify:
[tex]\displaystyle\lim_{ x\to 2}\frac{ \dfrac{d}{dx} (x^2)+ \dfrac{d}{dx} (x) + \dfrac{d}{dx}( -6)}{ \dfrac{d}{dx} (x^2) + \dfrac{d}{dx} (-4)}[/tex]
simplify using exponents using exponent derivative formula:
[tex]\displaystyle\lim_{ x\to 2}\frac{ 2x+ \dfrac{d}{dx} (x) + \dfrac{d}{dx}( -6)}{ 2x + \dfrac{d}{dx} (-4)}[/tex]
use variable derivative formula to simplify variable:
[tex]\displaystyle\lim_{ x\to 2}\frac{ 2x+ 1+ \dfrac{d}{dx}( -6)}{ 2x + \dfrac{d}{dx} (-4)}[/tex]
use constant derivative formula to simplify derivative:
[tex]\displaystyle\lim_{ x\to 2}\frac{ 2x+ 1+ 0}{ 2x + 0}[/tex]
simplify addition:
[tex]\displaystyle\lim_{ x\to 2}\frac{ 2x+ 1}{ 2x }[/tex]
since we are approaching x to 2
we can substitute 2 for x
[tex]\displaystyle\lim_{ x\to 2}\frac{ 2.2+ 1}{ 2.2 }[/tex]
simplify multiplication:
[tex]\displaystyle\frac{ 4+ 1}{ 4}[/tex]
simplify addition:
[tex] \displaystyle \: \frac{5}{4} [/tex]
hence,
[tex]\displaystyle\lim_{ x\to 2}\frac{ \dfrac{d}{dx} (x^2+x-6)}{ \dfrac{d}{dx} (x^2-4)} = \frac{5}{4} [/tex]

Find the surface area of each figure. Round your answers to the nearest hundredth, if necessary
Answer
238π yd^2
Step-by-step explanation:
here's your solution
=> height of cylinder = 10 yd
=> radius of cylinder = 7 yd
=> formula to calculate surface area = 2πr(h + r)
=> putting the value of height and radius in formula
=> SA = 2*22/7*7(10+7)
=>. SA = 2*22*17
=> SA = 748 yd.sq

Answer:
376.99 cm^3 or 120π cm^3
Step-by-step explanation:
The volume of a cone is 1/3(B*h) where B is the base area and h is height.
The base of a cone is a circle.
Area of a circle=πr^2
Area of the circle=π6^2
Area of the circle=36π
Plug it into the formula for the volume:
V=1/3(36π*10)
V=1/3(360π)
V=120π
V=376.99

Need help with this. Find the value of each variable.
Answer:
Step-by-step explanation:
By applying sine rule in ΔACD,
cos(30°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(30°) = [tex]\frac{CD}{AD}[/tex]
[tex]\frac{\sqrt{3} }{2}=\frac{z}{24}[/tex]
z = [tex]8\sqrt{3}[/tex]
By applying cosine rule in ΔACD,
sin(30°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(30°) = [tex]\frac{AC}{CD}[/tex]
[tex]\frac{1}{2}=\frac{AC}{24}[/tex]
AC = 12
By applying tangent rule in ΔACB,
tan(45°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
1 = [tex]\frac{AC}{BC}[/tex]
y = 12
By applying sine rule in ΔACB,
sin(45°) = [tex]\frac{BC}{AB}[/tex]
[tex]\frac{1}{\sqrt{2}}=\frac{y}{x}[/tex]
x = y(√2)
x = 12√2
Calculate the following using long division show all working 896 divided by 7
Answer:

What following number is in between 2/5 and 7/8?
15/16, 3/4, 3/8, 1/3
Answer:
Step-by-step explanation:
You need to give all the fractions a common denominator so you can compare the numerators.
The least common multiple of 5, 8, 16, 4, 3 is 240.
⅖ = 96/240
⅞ = 210/240
15/16 = 225/240
¾ = 180/240
⅜ = 90/240
⅓ = 80/240
The only numerator between 96 and 210 is 180.
180/240 = ¾
⅖ < ¾ < ⅞

Answer:
x = 11.8
Step-by-step explanation:
hypotenuse = 12
1 leg = 10 - 8 = 2
Formula:
a² + b² = c²
a² + 2² = 12²
a² + 4 = 144
a² = 144 - 4
a² = 140
[tex]\sqrt{a^2} =\sqrt{140}[/tex]
a = 11.8
Answer:
x = 11.8
Step-by-step explanation:
hypotenuse = 12
1 leg = 10 - 8 = 2
Formula:
a² + b² = c²
a² + 2² = 12²
a² + 4 = 144
a² = 144 - 4
a² = 140
Wayne types about 50 words per minute.A typical double spaced page contains 500 words.how long doe sit take Wayne to type 8 1/2 pages?
Answer:
Step-by-step explanation:
50t=500(8.5)
t=10(8.5)
t=85 minutes
Answer: 85 minutes
Step-by-step explanation:
First, find how many minutes it takes for Wayne to type a page containing 500 words. 500/50= 10 minutes
You then multiply that by 8
8(10)= 80 minutes to type 8 pages.
Now find how many words are in half a page.
500/2=250 words
Divide that by the amount of words Wayne can type per minute. 250/50= 5
Add that to the amount of minutes it took to type 8 pages. 85 minutes
Which is also 1 hour 25 minutes
what is the difference between 2/4 and 4/9
Answer:
Step-by-step explanation:
Here's how to subtract 4/9 from 2/4:
[tex]\frac{2}{4} -\frac{4}{9}[/tex]
Step 1:
We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.
So we multiply 2 by 9, and get 18.
Then we multiply 4 by 4, and get 16.
Next we give both terms new denominators -- 4 × 9 = 36.
So now our fractions look like this:
[tex]\frac{18}{36} -\frac{16}{36}[/tex]
Step 2
Since our denominators match, we can subtract the numerators.
18 − 16 = 2
So the answer is:
[tex]\frac{2}{36}[/tex]
Step 3
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?
To find out, we try dividing it by 2...
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
[tex]\frac{2}{36}[/tex]÷2=[tex]\frac{1}{8}[/tex]
Let's try dividing by 2 again...
No good. 2 is larger than 1. So we're done reducing.
There you have it! The final answer is:
[tex]\frac{1}{8}[/tex]

Answer:

Step-by-step explanation:
For this triangle to be a right triangle the following has to happen:
a^2 + b^2 = c^2
a=3, b=9, c= 12
3^2+9^2 does not equal 12^2
9+81 = 90 12^2 = 144
90 does not equal 144 so is not a right triangle
Answer:
see explanation
Step-by-step explanation:
Using converse of Pythagoras' identity
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = 12 , then 12² = 144
3² + 9² = 9 + 81 = 90 ≠ 144
Thus the triangle is not right.
