Answer:

yes it relates to a function

Answer:

A las 12:57 horas habrá 128 bacterias en el recipiente.

Step-by-step explanation:

Una función exponencial es aquella en que la variable independiente x aparece en el exponente y tiene de base una constante a. Su expresión es:

f(x)= aˣ

Siendo a un real positivo, a > 0, y diferente de 1.

Cuando 0 < a < 1, entonces la función exponencial es una función decreciente y cuando a > 1, es una función creciente.

Algunos tipos de bacterias se reproducen por "mitosis", dividiéndose la célula en dos cada espacios de tiempo pequeños, como sucede en este caso. Entonces, "a" tendrá un valor de 2, que es la cantidad en la que se divide la bacteria, y "x" será los intervalos de tiempo. Si hay 128 bacterias en el recipiente, la expresión exponencial del crecimiento de la bacteria en x intervalo de tiempo será:

2ˣ= 128

Una manera de resolver la x es aplicando logaritmos. Entonces, aplicando el logaritmo común de ambos lados. (Cuando la base no está escrita, se trata de la base 10):

log (2ˣ) = log (128)

Aplicando la propiedad de la potencia de los logaritmos:

x* log (2)= log (128)

x= log (128) ÷ log (2)

x= 7

Cada intervalo de tiempo tiene 6 minutos, que es el tiempo en que una bacteria se divide en 2. Entonces, el tiempo que se tarda en obtener 128 bacterias se calcula como:

7 intervalo* 6 minutos= 42 minutos

Si a las 12:15 horas se coloca una bacteria en un recipiente, entonces el horario a la que habrá 128 bacterias se calcula como:

12:15 + 42 minutos= 12:57

A las 12:57 horas habrá 128 bacterias en el recipiente.

Answer:

c=-2 and m=3

this is because the y intercept of the line given is -2 and if you find the slope is 3/1 or simplified to 3

Answer:

y = 1.4x + 5.6

Step-by-step explanation:

plug the slope and y-intercept into the formula: y = ax + b (a is the slope and b is the y-intercept)

thus, y = 1.4x + 5.6

Answer:

279 in.²

Step-by-step explanation:

square: 9 × 9 = 81

the 4 congruent triangles: 9 × 11 ÷ 2 = 49.5, 49.5 × 4 = 198

square + 4 congruent triangles = 81 + 198 = 279

Given:

The expression is:

[tex]\dfrac{15m^2-3}{3m-1}[/tex]

To find:

The simplified value of the given expression.

Solution:

We have,

[tex]\dfrac{15m^2-3}{3m-1}[/tex]

On dividing, we get

[tex](3m-1)|\overline{15m^2+0m-3}|5m+\dfrac{5}{3}[/tex]

          [tex]-(15m^2-5m)[/tex]

              [tex]\overline{\quad \quad -5m-3}[/tex]

                    [tex]-(5m-\dfrac{5}{3})[/tex]

                       [tex]\overline{\quad \quad -\dfrac{4}{3}}[/tex]

Here, quotient is [tex]5m+\dfrac{5}{3}[/tex]  and the remainder is  [tex]-\dfrac{4}{3}[/tex].

Therefore, [tex]\dfrac{15m^2-3}{3m-1}=5m+\dfrac{5}{3}-\dfrac{4}{3(3m-1)}[/tex].

In a circle, the parts of the diagonals multiply to equal each other, so 6·4=2x.

2x = 24, x = 12.

Answer:

Circumference = 17.4 cm

Step-by-step explanation:

A = π[tex]r^{2}[/tex]

24 = π[tex]r^{2}[/tex]

[tex]r^{2}[/tex] = 24/π

r = [tex]\sqrt{\frac{24}{\pi } }[/tex] = 2.7639...

d = 5.5279...

C = πd

   = π5.5279...

   = 17.4 cm

Answer:

Indirect variation

Rule: [tex]y = \frac{18}{x}[/tex]

Step-by-step explanation:

Given

[tex]x \to 2,3,4,5[/tex]

[tex]y \to 9,6,4.5,3.6[/tex]

Required

Determine the type of variation

For direct variation, we have:

y increases, as x increases

In the above function, y decreases, as x increases

Hence, it is not a direct variation

Indirect variation.

In an indirect variation, y decreases, as x increases

And the equation is given as:

[tex]y = \frac{k}{x}[/tex]

Make k the subject

[tex]k =xy[/tex]

Where k is the constant of variation.

For:

[tex](x,y) = (2,9)[/tex]

[tex]k = 2 * 9 = 18[/tex]

For:

[tex](x,y) = (3,6)[/tex]

[tex]k = 3 * 6 = 18[/tex]

For every other values;

[tex]k = x * y = 18[/tex]

Hence, it is an indirect variation.

The rule is:

[tex]y = \frac{k}{x}[/tex]

Substitute 18 for k

[tex]y = \frac{18}{x}[/tex]

Answer:

Sasha's grandma will need 48 square feet of fabric to sew the umbrella.

Step-by-step explanation:

Since Sasha's grandma is going to sew an umbrella for Sasha, which will be made of 4 identical triangles, if each triangle is 3 feet long and 4 feet high, to determine how many square feet of fabric does Sasha's grandma need, the following calculation must be done:

(3 x 4) x 4 = X

12 x 4 = X

48 = X

Therefore, Sasha's grandma will need 48 square feet of fabric to sew the umbrella.

Answer:

20.83 yard

Step-by-step explanation:

Calculate Cubic Yards

Calculate your area

Calculate your volume: Multiply area times the depth to get volume in cubic feet

Calculate your cubic yards: Divide cubic feet by 27 to convert to cubic yards and this is your answer

Where ft2 = square foot, ft3 = cubic foot, yd3 = cubic yard

Total yards = 5[x] + x + 8

Solve

133 = 6x + 8

6x = 125

x = 20.83 yard

Therefore, the Cyclone cleared 20.83 yards on the first day.

Step-by-step explanation:

Based on the calculations, the measure of angle m<SB rounded to the nearest tenth is equal to 0.70°.

In geometry, a tangent is also referred to as a tangent line and it can be defined as a straight line that touches a plane curve at a specific point.

Based on the diagram, we would apply the cosine function to determine the measure of the angle formed by the hypotenuse side of the triangle with respect to the radius of Earth (adjacent side):

m<SB = cos⁻¹(4000/4000 + 0.2) + cos⁻¹(4000/4000 + 0.01)

m<SB = cos⁻¹(4000/4000.2) + cos⁻¹(4000/4000.01)

m<SB = cos⁻¹(0.99995) + cos⁻¹(0.9999975)

m<SB = 0.573 + 0.128

m<SB = 0.701 ≈ 0.70°.
