Answer:
[tex]\dfrac{\text{d}y}{\text{d}x}=\cos(x)[/tex]
Step-by-step explanation:
Differentiating from First Principles is a technique to find an algebraic expression for the gradient at a particular point on the curve.
[tex]\boxed{\begin{minipage}{5.6 cm}\underline{Differentiating from First Principles}\\\\\\$\text{f}\:'(x)=\displaystyle \lim_{h \to 0} \left[\dfrac{\text{f}(x+h)-\text{f}(x)}{(x+h)-x}\right]$\\\\\end{minipage}}[/tex]
The point (x + h, f(x + h)) is a small distance along the curve from (x, f(x)).
As h gets smaller, the distance between the two points gets smaller.
The closer the points, the closer the line joining them will be to the tangent line.
To differentiate y = sin(x) using first principles, substitute f(x + h) = sin(x + h) and f(x) = sin(x) into the formula:
[tex]\implies \displaystyle \dfrac{\text{d}y}{\text{d}x}=\lim_{h \to 0} \left[\dfrac{\sin(x+h)-\sin(x)}{(x+h)-x}\right][/tex]
Use the sin addition formula to expand sin(x + h).
[tex]\boxed{\sin(A + B) = \sin A \cos B + \cos A \sin B}[/tex]
[tex]\implies \displaystyle \dfrac{\text{d}y}{\text{d}x}=\lim_{h \to 0} \left[\dfrac{\sin(x)\cos(h)+\cos(x)\sin(h)-\sin(x)}{(x+h)-x}\right][/tex]
[tex]\implies \displaystyle \dfrac{\text{d}y}{\text{d}x}=\lim_{h \to 0} \left[\dfrac{\sin(x)\cos(h)-\sin(x)+\cos(x)\sin(h)}{h}\right][/tex]
[tex]\implies \displaystyle \dfrac{\text{d}y}{\text{d}x}=\lim_{h \to 0} \left[\dfrac{\sin(x)(\cos(h)-1)+\cos(x)\sin(h)}{h}\right][/tex]
Separate the sin(x) and cos(x) terms into two fractions:
[tex]\implies \displaystyle \dfrac{\text{d}y}{\text{d}x}=\lim_{h \to 0} \left[\dfrac{\sin(x)(\cos(h)-1)}{h}+\dfrac{\cos(x)\sin(h)}{h}\right][/tex]
When h gets really small, we can use the small angle approximation to rewrite cos(h).
[tex]\boxed{\cos (h) \approx 1-\dfrac{1}{2}h^2}[/tex]
[tex]\implies \displaystyle \dfrac{\text{d}y}{\text{d}x}=\lim_{h \to 0} \left[\dfrac{\sin(x)\left(1-\dfrac{1}{2}h^2-1\right)}{h}+\dfrac{\cos(x)\cdot h}{h}\right][/tex]
[tex]\implies \displaystyle \dfrac{\text{d}y}{\text{d}x}=\lim_{h \to 0} \left[\dfrac{\sin(x)\left(-\dfrac{1}{2}h^2\right)}{h}+\dfrac{\cos(x)\cdot h}{h}\right][/tex]
Cancel the common factor, h:
[tex]\implies \displaystyle \dfrac{\text{d}y}{\text{d}x}=\lim_{h \to 0} \left[-\dfrac{1}{2}h\sin(x)+\cos(x)\right][/tex]
As h → 0, the first term → 0:
[tex]\implies \displaystyle \dfrac{\text{d}y}{\text{d}x}=\cos(x)[/tex]

The required measure of angle p in triangle DBC is given as ∠p = 59.14°.
What are trig ratios?If you know the lengths of two sides of a right triangle, you can use trigonometric ratios to calculate the measures of one (or both) of the acute angles.
Here,
Consider triangle ABD
Apply the Pythagorean theorem to determine the measure of DB,
DB² = AD² + AB²
DB² = 6² + 5²
DB² = 61
DB = 7.81
Now,
Apply the trig ratio in triangle DCB,
cosp = 4/7.81
p = 59.14°
Thus, the required measure of angle p in triangle DBC is given as ∠p = 59.14°.

Jason wants to dine at five different restaurants during a summer getaway. If three of nine available restaurants serve seafood, find the number of ways that at least one
of the selected restaurants will serve seafood given the following conditions.
(a) The order of selection is important.
(b) The order of selection is not important.
(a) If the order is important, then the number of ways that at least one of the selected restaurants will serve seafood is
answer
C(9, 5) - C(6, 5) + C(3, 1) = 126 - 6 + 3 = 123
explanation
The first term, C(9, 5), represents the number of ways to select 5 restaurants out of 9, regardless of type. The second term, C(6, 5), represents the number of ways to select 5 non-seafood restaurants out of 6. To find the number of ways that at least one of the selected restaurants will serve seafood, we subtract the number of ways to select 5 non-seafood restaurants and add the number of ways to select exactly 1 seafood restaurant, represented by C(3, 1).
The result, 123, represents the number of ways that at least one of the selected restaurants will serve seafood.

Give the domain of
s(x)=6/25-x^2
Answer: The domain of a function is the set of all possible input values (x-values) for which the function is defined and produces a valid output (y-value).
In this case, the function s(x) = 6/25 - x^2 has no restrictions on the input values for x, so the domain of the function is all real numbers.
Therefore, the domain of the function s(x) = 6/25 - x^2 is:
(-∞, ∞)
This means that the function can be evaluated for any real value of x.

What is r in the following equation? 5(-4) - r +1 = -37 PLEASE HELPP ILL GIVE EXTRA CREDIT
Answer:
Step-by-step explanation:
5 times -4 is -20, so the equation becomes -20 - r + 1 = -37
-20 plus 1 equals -19, so the equation is now -19 - r = -37
Then you add 19 to both sides to isolate r
-r = -18
To get a positive r, divide or multiply both sides by -1, and you get r = 18
[tex]5(-4)-r+1=-37[/tex]
Simplify:
[tex]-20-r+1=-37[/tex]
Combine Like Terms:
[tex](-r)+(-20+1)=-37[/tex]
[tex]-r-19=-37[/tex]
Add 19 to both sides:
[tex]-r-19+19=-37+19[/tex]
[tex]-r=-18[/tex]
Divide both sides by -1:(To remove the negative from the variable r)
[tex]\dfrac{-r}{-1}=\dfrac{-18}{-1}[/tex]

Sketch an angle θ in standard position such that θ has the least possible positive measure and the point (−3,4) is on the terminal side of θ. Then find the exact values of the six trigonometric functions for θ.
To sketch the angle θ in standard position, you can start by plotting the point ( -3, 4 ) on the coordinate plane. Next, you draw a line from the origin ( 0, 0 ) to the point ( -3, 4 ), which represents the terminal side of the angle.
Now, you can use the six trigonometric functions to find the exact values for θ:
Cosine ( cos θ ) = x / r = -3 / 5
Sine ( sin θ ) = y / r = 4 / 5
Tangent ( tan θ ) = y / x = 4 / -3
Secant ( sec θ ) = 1 / cos θ = -5 / 3
Cosecant ( csc θ ) = 1 / sin θ = -5 / 4
Cotangent ( cot θ ) = 1 / tan θ = -3 / 4
Here, r represents the distance from the origin to the point ( -3, 4 ), which is 5 units. Note that these values are for the least positive measure of the angle, which is in the second quadrant.

The probability that someone files their taxes late is 0.351. If you are questioning 10 people, what is the probability
that 6 of them filed their taxes on time.
Answer:
0.209.
Step-by-step explanation:
The probability that someone files their taxes on time is 1 - 0.351 = 0.649.
To find the probability that 6 out of 10 people file their taxes on time, we can use the binomial distribution. The binomial formula for the probability of k success in n trials is given by:
P(k) = (n choose k) * p^k * (1-p)^(n-k)
Where (n choose k) is the number of combinations of n items taken k at a time, and p is the probability of success in a single trial.
So, for the problem at hand:
P(6) = (10 choose 6) * 0.649^6 * (1 - 0.649)^(10 - 6) = 0.209
Therefore, the probability that 6 out of 10 people file their taxes on time is approximately 0.209.
