Answer:
[tex]f' \left(\dfrac{\pi}{3}\right) =\dfrac{1}{2}[/tex]
Step-by-step explanation:
Given function:
[tex]f(x)=\sin x[/tex]
The differentiation of sin(x) is cos(x).
[tex]\implies f'(x)=\cos x[/tex]
Therefore:
[tex]\implies f' \left(\dfrac{\pi}{3}\right) = \cos \left(\dfrac{\pi}{3}\right)[/tex]
[tex]\implies f' \left(\dfrac{\pi}{3}\right) =\dfrac{1}{2}[/tex]

You can multiply two matrices only if their dimensions are compatible. That means the number of columns in the first matrix is equal to the number of rows in the second matrix.
The resulting matrix, called the matrix product, has the number of rows of the first and the range of columns of the second matrix. The result of matrices A and B is denoted as AB.
The definition of matrix multiplication means row-by-column multiplication, where the entry in the ith row of A is multiplied by the corresponding entry in the jth column of B, and the results are added. Matrix multiplication is not commutative. If neither A nor B is identity matrices, then AB≠BA.

The ratio shows how many times one value is contained in another value.
The number of pigs is 44.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
The number of pigs: the number of goats = 11:3
Let the number of pigs = 11x
Let the number of goats = 3x
The number of goats = 12
This means,
3x = 12
Divide 3 on both sides.
x = 12/3
x = 4
Now,
The number of pigs:
= 11x
= 11 x 4
= 44
Thus,
The number of pigs is 44.

You have here a multiplication and a division in your expression. You need to multiply and divide in the order that they appear from left to right, according to the order of operations. So multiply first.
To multiply two fractions, you just multiply the top×top and bottom×bottom.
You could simplify it at this point but I waited to the end to simplify. See image.
Next, divide. If you have one or two fractions in a division problem, rewrite the division as a multiplication using Keep-Change-Flip! Keep the first term. Change divide to multiply. And Flip the second term (use the reciprocal is the math word for it.) See image.
Last, simplify.

Write a function for each situation. Then find the value of each function after five years. Round to the nearest dollar. A $ 12,500 car depreciates 9 % each year.
7800 is the value of each function after five years.
With an example, what is compound interest?
When you add the interest you have already earned back into your principal balance, you are earning compound interest, which increases your profits. Consider that you have $1,000 in a savings account earning 5% interest annually. If you made $50 in the first year, your new balance would be $1,050.The formula is: A = P( 1 + r )ⁿ
r = 0.09
As here the value of the car depreciates every year, so we need to plug the value of as negative. So, - 0.09
Now plugging the above values into the formula, we will get
A = 12500 ( 1 - 0.09)⁵
A = 12500 * ( 0.91)⁵
A = 12500 * 0.6240321451
A = 7800.40181375 ≈ 7800

A kitten has 5 claws on its paw, a chicken has 4. there are 57 kittens and chickens in the yard and they all have 768 claws. how many kittens and chickens are in the yard?
Using algebraic expressions and equation, there are 26 kittens and 31 chickens in the yard.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
Given that there are 57 kittens and chickens in the yard, we can express this as:
x + y = 57 ⇒ x = 57 - y (equation 1)
where x = number of kittens
y = number of chickens
If a kitten has 5 claws on each of its 4 paws, and a chicken has 4 claws in each of its 2 feet, and they all have 768 claws, then
5(4)x + 4(2)y = 768 ⇒ 20x + 8y = 768 (equation 2)
Substitute equation 1 to equation 2 and solve for y.
20(57 - y) + 8y = 768
1140 - 20y + 8y = 768
-12y = -372
y = 31
number of chickens = 31
Substitute the value of y in either of the two equations and solve for x.
x = 57 - y
x = 57 - 31
x = 26
number of kittens = 26

What is the value is 1/a+1/b+1/c
When a, b and c are the polynomials roots
Answer:
2/3.
Step-by-step explanation:
α + β + γ = -b/a
αβ + βγ + γ α = c/a
αβγ = -d/a
These are the relation between the roots α, β and γ and the coefficients of the cubic equation:
P(x) = ax^3 + bx^2 + cx + d
Our equation is:
P(x) = 4x³ – x² − 6x + 9
So, for the above equation:
a + b + c = -(-1)/4 = 1/4
ab + ac + bc = -6/4 = -3/2
abc = -9/4.
1/a + 1/b + 1/c
= (bc + ac + ab) / abc
So, plugging in the above values:
this = (-3/2) / (-9/4)
= 3/2 * 4/9
