The solution of the function f(x) = 13 is x= 3

According to the question we have been the function f(x), that i s

   f(x) = x² + 4

We need to find the value of x where we have been given that

  f(x) = 13

Therefore, we will put the required value of function f(x) in the above condition we get

 x² + 4 = 13

Subtracting 4 both the sides we get,

 x² + 4 - 4 = 13 - 4

 x² = 9

Taking square root both sides we get,

√x² = √9

  x = 3

Hence the value of x is 3.

Scientific notation is a way to present extremely large or extremely small numbers in a more understandable way. We are aware that full numbers can go on forever, but we are unable to write such enormous figures on paper. Additionally, a simpler method of representation was required for the numbers that appear at the millions place after the decimal. This makes it challenging to represent a small number of integers in their enlarged form. We therefore employ scientific notations.

Mario viaja 48 segundos para encontrarse con Luis.

La distancia se define como la longitud de la trayectoria real recorrida por una partícula en movimiento. El desplazamiento se define como la distancia más corta entre la posición inicial y final de un cuerpo. La distancia recorrida por una partícula en una unidad de tiempo se conoce como velocidad.

La distancia entre Luis y Mario es de 240 metros.

La velocidad al caminar de Luis es de 3 m/s.

La velocidad al caminar de Mario es de 5 m/s.

La distancia se puede definir como el producto de la velocidad y el tiempo que tarda el objeto.

Por lo tanto,

Para que Mario alcance a Luis,

Distancia = Velocidad × Tiempo

240 = 5 × t

t = 240/5 = 48 sec.

The perimeter of square STUV is 32.98 units

From the question, we are to calculate the perimeter of the given square.

To do this, we will determine one side length of the given square

The length of a side is the distance between the two end points

Using the points U and T

U(-7, 9) and T(1, 7)

Using the formula for the distance between two points

d = √(x₂ - x₁)² + (y₂-y₁)²

x₁ = -7

y₁ = 9

x₂ = 1

y₂ = 7

Thus,

The distance, d, between the points is

d = √(1 - -7)² + (7-9)²

d = √(1 +7)² + (-2)²

d = √(8)² + 4

d = √64+ 4

d = √68

d = 8.2462

This means the length of each side of the square is 8.2462 units

l = 8.2462 units

The perimeter, P, of a square is given by

P = 4l

P = 4 × 8.2462

P = 32.9848

P ≈ 32.98 units

Hence, the perimeter of square STUV is 32.98 units

As per given condition of Joyce bought twice of she had at first ,number of stickers bought by Joyce is equal to 32.

As given in the question,

Let x represents the number of Michelle stickers

and y represents the number of Joyce stickers

As per given condition,

Michelle and Joyce had an equal number of stickers

x =y __(1)

Joyce bought twice she had at first and had 4 times as many stickers as Michelle

2y = 4(x-8) __(2)

From (1) and (2) ,

2y = 4 ( y-8)

⇒ 2y = 4y -32

⇒4y -2y = 32

⇒ 2y = 32

Therefore, as per given condition of Joyce bought twice of she had at first ,number of stickers bought by Joyce is equal to 32.

300 and 30 respectively

Step-by-step explanation:

The 3 in each number can be valued at 3 with the same number of 0s as there are digits to the right of the 3.

For example, in 6300, the 3 stands for 300 because there are two digits (0 and 0) to the right of 3. So we know 3 stands for 300 because we add two 0s to the right of 3.

Simplifying  the quantity 10 minus three fourths times the square root of 16 end quantity squared plus the quantity 2 minus 7 end quantity squared is: c. 74.

Sharon's annual percentage yield (APY) to the nearest hundredth of a

percent is; 2.02%

We are told that;

Amount Deposited = $8000

Interest = 2%

Using the formula for annual percentage yield (APY), we have;

B = 8000 + (1 + (0.02/365))³⁶⁵⁽¹⁾

B = $8161.61

Interest is;

I = $8161.61 - $8,000

I = $161.61

Using derivatives, the equation for the marginal product of labor is given by:

Q'(L) = 5 - 2L.

As stated in the problem, the “marginal product of labor” is the change in the total product as we change the amount of hired labor, hence it is given by the derivative of the production as a function of labor.

For this problem, the production function is given by:

Q(L) = 5L - L².

Hence the marginal product of labor is given by:

Q'(L) = 5 - 2L.

Which is the derivative of Q(L), found applying the derivative of a power of x, as follows:

[x^n]' = nx^(n-1).
