Answer:

The decay rate of the medication is approximately [tex]0.116\,\frac{1}{h}[/tex].

Step-by-step explanation:

If we know that amount of medication decays exponentially, this amount is represented by the following expression:

[tex]n(t) = n_{o}\cdot e^{-\lambda\cdot t}[/tex] (1)

Where:

[tex]n_{o}[/tex] - Initial amount of medication.

[tex]n(t)[/tex] - Current amount of medication.

[tex]t[/tex] - Time, measured in hours.

[tex]\lambda[/tex] - Decay rate, measured in [tex]\frac{1}{h}[/tex].

In addition, the decay rate is determined by the following formula:

[tex]\lambda = \frac{\ln 2}{t_{1/2}}[/tex] (2)

If we know that [tex]t_{1/2} = 6\,h[/tex], then the decay rate is:

[tex]\lambda = \frac{\ln 2}{6\,h}[/tex]

[tex]\lambda \approx 0.116\,\frac{1}{h}[/tex]

The decay rate of the medication is approximately [tex]0.116\,\frac{1}{h}[/tex].

Answer:

The equation of the linear function is f(x) = -3x - 4

Step-by-step explanation:

The form of the equation of the linear function is f(x) = m x + b, where

The rule of the slope is m = Δy/Δx, where

∵ f(x) = y

∴ The coordinates of any point belongs to the function are (x, y)

∵ f(-4) = 8 and f(2) = -10

∴ The points are (-4, 8) and (2, -10)

∵ x1 = -4 and y1 = 8

∵ x2 = 2 and y2 = -10

→ Find Δx and Δy

∴ Δx = 2 - (-4) = 2 + 4 = 6

∴ Δy = -10 - 8 = -18

→ Substitute them in the rule of the slope

∵ m = [tex]\frac{-18}{6}[/tex]

∴ m = -3

→ Substitute it in the form of the equation above

∴ f(x) = -3x + b

→ To find b substitute x by -4 and f(x) by 8

∵ 8 = -3(-4) + b

∴ 8 = 12 + b

→ Subtract 12 from both sides

∵ 8 - 12 = 12 - 12 + b

∴ -4 = b

→ Substitute it in the equation

∴ f(x) = -3x + (-4)

∴ f(x) = -3x - 4

∴ The equation of the linear function is f(x) = -3x - 4

Answer:

h = -12/23

Step-by-step explanation:

Combine like terms:

32h + 24 = -3h - 11h

32h + 24 = -14h

Subtract 24 from both sides of the equation:

32h + 24 = -14h

32h + 24 - 24 = -14 h - 24

Simplify:

32h = -14h - 24

Add 14 to both sides and then you simplify. This will give you the answer -12/23. Good luck!!

Answer:

A. The lowest point of the hammock is at the point 1 meters above the ground and 3 meters from one end of the hammock

B. The two trees are 6 meters away from one another

Step-by-step explanation:

The given equation of the parabola representing the hammock is as follows;

y = 0.4·(x - 3)² + 1

The general equation of a parabola is a·(x - h)² + k;

Where the coordinates of the vertex point of the parabola, which is the lowest (or highest, furthest) point on the vertex is (h, k) = (3, 1)

Therefore, we have;

A, The coordinates of the lowest point on the hammock is (3, 1)

Therefore, the lowest point of the hammock is at 1 meters above the ground and 3 meters from one end of the hammock

B.  Given that the distance from one end is "x", we have;

The height at which the hammock is attached is given as the point where x = 0 as follows;

Given that the vertex of the parabola represents the axis of symmetry of the parabola, we have that the horizontal distance from one end of the hammock to the vertex point of the parabola that the hammock forms is (3 - 0) meters = 3 meters

Therefore, by the definition of symmetry, the distance from the vertex point to the other end of the parabola that the hammock forms is also 3 meters

From which we have, the distance the two trees are from one another is 3 meters + 3 meters = 6 meters.

Answer:

the cities are 3.5 cm apart.

Step-by-step explanation:

all you have to do is divide 280/80

Answer:

C

Step-by-step explanation:

Absolute value makes anything in it positive, as distance from 0 can only be positive. So if we apply that to every term, we can find the answer.

For a, simplify and it becomes 15>19. That's false

For b, simplify and it becomes 16<13. Also false

For c, simplify and it becomes 15>12. True

For d, simplify and it becomes 12<8. False

For e, simplify and it becomes 19>20. Very False.

So the only true one is C. So C is the answer.

Hope this helped.

Answer:

divide it by 100

Step-by-step explanation:

5.2 ÷ 100 = 0.052

The required 5.2 divided by 100 gives the quotient of 0.052​.

Given that,
5.2 divided by blank =0.052​, A value that is best suitable for the blank is to be determined.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

let the number be x,
According to the question,
5.2 / x - 0.052
x = 5.2/0.052
x = 5200/52
x = 100

Thus, the required divisor of the given numeral is 100.

#teamtrees #WAP (Water And Plant)

Answer:

Step-by-step explanation:

     4x+8                  27

L-------------M-------------------------N

<------------------ 6x -------------------->

LM = 4x+8

MN = 27

LN = 6x

LM + MN = LN

4x+8 + 27 = 6x

35 = 2x

17.5 = x

LN = 6x = 6(17.5) = 105

The correct answer to the question is: x = 17.5, LN = 105

From the question given above, we obtained the following:

LN = 6x

LM = 4x + 8

MN = 27

The value of x can be obtained as follow:

LN =  LM + MN

6x = 4x + 8 + 27

6x = 4x + 35

Collect like terms

6x – 4x = 35

2x = 35

Divide both side by 2

x = 35 / 2

x = 17.5

LN =?

LN = 6x

LN = 6(17.5)

Therefore, the correct answer to the question is: x = 17.5, LN = 105

Answer:

a = 49°

Step-by-step explanation:

From the figure attached,

In ΔBOC,

OB = OC = Radii of the circle O

Therefore, m∠OBC = m∠OCB = 41° [Opposite angles of the equal sides of a triangle]

By triangle sum theorem,

m∠OBC + m∠OCB + m∠BOC = 180°

41° + 41° + m∠BOC = 180°

m∠BOC = 180° - 82°

              = 98°

Since, "angle subtended by an arc at the center is twice the angle subtended at the circumference",

m∠BOC = 2(m∠BAC)

98° = 2(a)

a = 49°

A company has two manufacturing plants with daily production levels of 5x + 11 items and 2x - 3 items, respectively, where x represents a minimum quantity. The first plant produces how many more items daily than the second plant?

Answer:

3x + 14

Step-by-step explanation:

Given that:

Production level of plant 1 = 5x + 11

Production level of plant 2 = 2x - 3

The first plant produces how many more items daily than the second plant :

Plant 1 production - plant 2 production

(5x + 11) - (2x - 3)

Open the bracket :

5x + 11 - 2x + 3

5x - 2x + 11 + 3
