4. Find the derivative of sin x from first principle.
Step-by-step explanation:
[tex]\text{By First Principle,}[/tex]
[tex]\begin{align}\dfrac{d}{dx}\sin x&=\lim_{h\to0}\frac{\sin(x+h)-\sin x}{h}\\&=\lim_{h\to0}\frac{\sin x\cos h+\sin h\cos x-\sin x}{h}\\&=\lim_{h\to0}\left(\frac{\cos h-1}{h}\cdot\sin x\right)+\lim_{h\to0}\left(\frac{\sin h}{h}\cdot\cos x\right)\\&=\sin x\cdot\left(\lim_{h\to0}\frac{\cos h-1}{h}\right)+\cos x\cdot\lim_{h\to0}\left(\frac{\sin h}{h}\right)\\&=\sin x\cdot 0+\cos x\cdot1\\&=\cos x\end{align}[/tex]

describe all equation of motion
Answer:
First equation
from definition of acceleration:
[tex]a = \frac{change \: in \: velocity}{time} \\ \\ a = \frac{v - u}{t} \\ \\ at = v - u\\ { \boxed{v = u + at}}[/tex]
Second equation
from displacement:
[tex]s = (average \: velocity) \times time \\ s = ( \frac{v + u}{2} ) \times t \\ \\ 2s = (v + u)t[/tex]
but v is u + at :
[tex]2s = \{(u + at) + u \} \times t \\ \\ 2s = (2u + at)t \\ 2s = 2ut + {at}^{2} \\ s = \frac{2ut}{2} + \frac{a {t}^{2} }{2} \\ \\ { \boxed{s = ut + \frac{1}{2} {at}^{2} }}[/tex]
third equation
from displacement:
[tex]s = ( \frac{v + u}{2} )( \frac{v - u}{a} ) \\ \\ 2as = (v + u)(v - u) \\ 2as = {v}^{2} - {u }^{2} \\ \\ { \boxed{ {v}^{2} = {u}^{2} + 2as }}[/tex]

We are supposed to factor this cube sum. I will give 100 points and brainliest to anybody that answers this with a VERY detailed explanation.
Answer:
y(y² + 1)(y² - y - 1)(y² + y - 1)Step-by-step explanation:
y⁷ + y = y(y⁶ + 1) = y((y²)³ + 1³) = y(y² + 1)(y⁴ - y² + 1) = y(y² + 1)(y⁴ - 2y² + 1 - y²) = y(y² + 1)((y² - 1)² - y²) = y(y² + 1)(y² - y - 1)(y² + y - 1)Used identities:
a³ + b³ = (a + b)(a² - ab + b²)a² - b² = (a + b)(a - b)a² - 2ab + b² = (a - b)²Algebra
= y⁷ + y
= y(y⁶ + 1³)
= y(y² + 1)(y⁴ - 2y² + 1 - y²)
= y(y² + 1)(y² - y - 1)(y² - y - 1)

harold licorice company made 6,429.4 feet of licorice in 9 days. to the nearest hundredth of a foot how many feet of licorice on average did the company make per day
Answer: 714.4
Step-by-step explanation: It says the company had made 6,429.4 feet of licorice in 9 days and you want to find the average amount made in 1 day. So what you would do is divide 6,429.4 by 9 and get 714.3777777 so on. Next its says by the nearest hundredths place meaning the 2nd placement after the dot, so what you would do is round it and you get 714.4.

Anyone know how to do this
Answer:
Look in explanation
Step-by-step explanation:
I will assume that you're trying to solve for "x".
For number 1: 49+(5x+1) is a supplementary angle(180 degrees) so you can subtract 180-49 to get 131.
Now, 131 = 5x+1
-1 -1
130 = 5x
/5 /5
Now, we isolate the x to get x=26.
Number 2: There is a supplementary angle as well so we can put 5x+12+6x+3=180.
Now, combine the like terms to get 11x+15=180 so we now isolate x.
-15 -15
11x=165
/11 /11
x=15
Now, try the rest and set the terms to 180.
5x+1+8+4x=180
2x+1+x-10=180
6+x+5x=180
x+2+153=180(This is similar to #1)

-3x-y=4 Slope-intercept form?
Answer:
y = -3x - 4
Step-by-step explanation:
-3x - y = 4
~Add 3x to both sides
-y = 4 + 3x
~Divide -1 to everything
y = -4 - 3x
~Reorder
y = -3x - 4
Best of Luck!
