A. Differentiate the following functions using product rule and quotient rule.
B. Differentiate the following using Chain Rule.
The following results by product rule and quotient rule are listed below:
[tex]f'(x) = 3\cdot x^{2}-15\cdot x - 9[/tex][tex]f'(x) = \frac{15}{2} \cdot x^{4}-6\cdot x^{3}+\frac{45}{2}\cdot x^{2}-\frac{81}{2} \cdot x +13[/tex][tex]f'(x) = \frac{90\cdot x^{2}-45\cdot x^{2}-40\cdot x +72}{25\cdot x^{4}-80\cdot x^{2}+64}[/tex][tex]f'(x) = \frac{\left(9\cdot x^{2}-18\cdot x-6\right)\cdot \left(\frac{x^{2}}{2}+7\cdot x-8 \right)-\left(3\cdot x^{3}-9\cdot x^{2}-6\cdot x +1 \right)\cdot \left(\frac{2}{3}\cdot x+7 \right)}{\left(\frac{x^{2}}{2}+7\cdot x-8 \right)^{2}}[/tex]
The following results by chain rule are listed below:
[tex]f'(x) = 3\cdot (2\cdot x^{2}-2\cdot x +1)^{2}\cdot (4\cdot x-2)[/tex][tex]f'(x) = \frac{15\cdot x^{2}-16\cdot x+9}{2\cdot \sqrt{5\cdot x^{3}-8\cdot x^{2}+9\cdot x-6}}[/tex][tex]f'(x) = \frac{2\cdot \left(6\cdot x-\frac{2}{3}-4\cdot x^{-5} \right)}{3\cdot \sqrt[3]{3\cdot x^{2}-\frac{2}{3}\cdot x +x^{-4} } }[/tex]How to apply product rule and quotient rule to obtain the derivative of function
In this part we must apply the following rules to calculate the derivatives:
Product rule[tex]\frac{d}{dx}[f(x)\cdot g(x)] = f'(x) \cdot g(x) + f(x) \cdot g'(x)[/tex] (1)
Quotient rule
[tex]\frac{d}{dx}\left[\frac{f(x)}{g(x)} \right] = \frac{f'(x)\cdot g(x)-f(x)\cdot g'(x)}{[g(x)]^{2}}[/tex] (2)
Now we proceed to obtain each expression:
1) [tex]f'(x) = 3\cdot x\cdot (x-6)+3\cdot x-9[/tex]
[tex]f'(x) = 3\cdot x^{2}-15\cdot x - 9[/tex] [tex]\blacksquare[/tex]
2) [tex]f'(x) = \left(\frac{9}{4}\cdot x^{2}-4\cdot x+\frac{1}{4}\right)\cdot (2\cdot x^{2}-2\cdot x + 4) + \left(\frac{3}{4}\cdot x^{3}-2\cdot x^{2}+\frac{x}{4}-6\right)\cdot (4\cdot x-2)[/tex]
[tex]f'(x) = \frac{9}{2}\cdot x^{4}-8\cdot x^{3}+\frac{1}{2}\cdot x^{2}-\frac{9}{2}\cdot x^{3}+8\cdot x^{2}-\frac{x}{2}+9\cdot x^{2}-16\cdot x+1 +3\cdot x^{4}-8\cdot x^{3}+x^{2}-24\cdot x-\frac{3}{2}\cdot x^{3}+4\cdot x^{2}-\frac{x}{2} +12[/tex]
[tex]f'(x) = \left(\frac{9}{2}+3 \right)\cdot x^{4}+\left(-8-\frac{9}{2}+8-\frac{3}{2} \right)\cdot x^{3} + \left(\frac{1}{2}+8+9+1+4 \right)\cdot x^{2} + \left(-16-24-\frac{1}{2} \right)\cdot x + \left(1+12\right)[/tex]
[tex]f'(x) = \frac{15}{2} \cdot x^{4}-6\cdot x^{3}+\frac{45}{2}\cdot x^{2}-\frac{81}{2} \cdot x +13[/tex] [tex]\blacksquare[/tex]
3) [tex]f'(x) = \frac{-9\cdot (5\cdot x^{2}-8)-(-9\cdot x+4)\cdot (10\cdot x)}{(5\cdot x^{2}-8)^{2}}[/tex]
[tex]f'(x) = \frac{-45\cdot x^{2}+72+90\cdot x^{2}-40\cdot x}{25\cdot x^{4}-80\cdot x^{2}+64}[/tex]
[tex]f'(x) = \frac{90\cdot x^{2}-45\cdot x^{2}-40\cdot x +72}{25\cdot x^{4}-80\cdot x^{2}+64}[/tex] [tex]\blacksquare[/tex]
4) [tex]f'(x) = \frac{\left(9\cdot x^{2}-18\cdot x-6\right)\cdot \left(\frac{x^{2}}{2}+7\cdot x-8 \right)-\left(3\cdot x^{3}-9\cdot x^{2}-6\cdot x +1 \right)\cdot \left(\frac{2}{3}\cdot x+7 \right)}{\left(\frac{x^{2}}{2}+7\cdot x-8 \right)^{2}}[/tex] [tex]\blacksquare[/tex]
How to apply chain rule to find derivativesLet be a function of the form [tex]f[u(x)][/tex], the derivative of this function is defined by the following rule:
[tex]\frac{d}{dx}[f[u(x)]] = \frac{df}{du}\cdot \frac{du}{dx}[/tex]
Now we proceed to present the following results:

1.9x-0.8y=10 what is x
Answer: x = 0.421053y+5.263158
Step-by-step explanation:
x = 0.421053y+5.263158
Answer:
x=0.042105y+10/19
Step-by-step explanation:
Let's solve for x.
19x−0.8y=10
Step 1: Add 0.8y to both sides.
19x−0.8y+0.8y=10+0.8y
19x=0.8y+10
Step 2: Divide both sides by 19.
19x/19=0.8y+10/19
x=0.042105y+10/19

Find the substitution 2x+3y=-5 and y=-x+5
Answer: x = 20, y = -15
Step-by-step explanation:
Since we already know that [tex]y=-x+5[/tex], we can just substitute in that value of y into the other equation:
[tex]2x+3y=-5\\2x+3(-x+5)=-5\\2x-3x+15=-5\\-x=-5-15\\-x=-20\\x=20[/tex]
with the value of x, we can find the value of y:

Is it possible to build a triangle with the side lengths of 9,7, and 16?
Please help! 11pts!!
Answer:
False
Step-by-step explanation:
To be able to build a triangle, the sum of the lengths of any 2 sides must be greater than the length of the third side.
With lengths 9, 7, and 16, 9 + 7 = 16.
You would need 9 + 7 > 16.
Therefore, these sides cannot be used for a triangle.

For a school fundraiser, Elena will make pirate masks. She will order masks and print graphics on them. Elena must spend $349 on the printer before she can print any masks and then $4.80 on each mask. If she has $997 how many masks can she print? Answer as a number!
Answer:
135 masks
Step-by-step explanation:
i hope my math is right lol
Answer:
135 masks
Step-by-step explanation:
First, we take $997 and subtract that by $349
$997 - $349 = $648
To find how many masks Elena can print, we divide $648 dollars by $4.80. Since one mask is equivalent to $4.80
$648 ÷ $4.80 = 135
135 masks

The sum of two consecutive integers is – 175. Find the two integers.
Answer:
-88 and -87
Step-by-step explanation:
Since the two unknown integers are consecutive, one will be one more than the other. This means we can express them as x and x+1, so we only have one unknown in our equation. Since they add to -175, we can now write our equation:
x+(x+1) = -175
Take away brackets and combine like terms:
2x+1 = -175
Now we just need to isolate x which we can do by subtracting 1 from both sides and then dividing both sides by 2:
2x+1-1=-175-1
2x = -176
2x/2 = -176/2
x = -88
And our other number is -88+1 = -87
So our two numbers are -88 and -87 which are consecutive and add to 176:
-88+(-87) = -175

In a race, a bicyclist travels 3 miles in 1/4 hour. Determine the unit rate for the speed
in miles per hour.
3/4 miles per hour
16 miles per hour
11/4 miles per hour
12 miles per hour
Step-by-step explanation:
the standard measure for speed is
miles per hour.
now we got as measurement
3 miles per 1/4 hour.
to give the standard speed or "unit rate" we assume that the bicyclist maintains the same speed for a whole hour.
and the question is : how many miles is he traveling then in that 1 hour ?
to answer this we have to check how often the actually measured unit of time fits into 1 hour.
1/4 hour fits 4 times into 1 hour.
and that factor applies now also to the miles to keep the value of the rate or ratio unchanged :
miles/time × a/a = miles×a/(time×a)
so that (time×a) = 1 hour
and so, he traveled 3×4 = 12 miles per hour.

Answer:
1/2
Step-by-step explanation:
I got it wrong then it gave me the right answer of 1/2
The fraction of the sweaters that cost $50 or less is 50% is 1/2.
What is a median?It is the middle value of the given set of numbers after arranging the given set of numbers in order.
We have,
From the box plot,
Median = $50
Now,
Median = $50
This means,
50% of the clothes are above $50 and 50% of the clothes are below $50.
Now,
The fraction of the sweaters that cost $50 or less is 50%.
So,
= 50/100
= 5/10
= 1/2
Thus,
The fraction of the sweaters that cost $50 or less is 50% is 1/2.
