Answer:

Step-by-step explanation:

(\frac{1}{9})(\frac{2}{3})^x=(\frac{12}{243})\\(\frac{2}{3})^x=\frac {12}{243} \times \frac {9}{1}=\frac{4}{9}=(\frac{2}{3})^2 \\x=2

A 22 gram sample of a substance that's used to preserve fruit and vegetables has a k-value of 0.1011. Find the substance's half-
Eddi Din [679]
 <span>Formula for exponential decay is: 

N = No * e^-kt 

N = 1/2(45) = 22.5 

No = 45 

k = 0.1109 
The solution to your problem is as follows:

Let's try to solve the half-life if it is 45 grams, after which, you will now have an idea on how to solve the problem.

22.5 = 45 * e^(-0.1109t) 

1/2 = e^(-0.1109t) 

ln(1/2) = -0.1109t 

t = (ln(1/2))/(-0.1109) = 6.25 days

Make m the subject of g-3m=am+5​
Salsk061 [2.6K]

Answer:

m = (g - 5) / (a + 3)

Step-by-step explanation:

g-3m=am+5​

  • Get all the m's on one side.

g - 5 = am + 3m

  • Combine the m's into one term, using brackets

g - 5 = (a + 3)m

  • Get m on it's own by dividing by a + 3

(g - 5) / (a + 3) = m

A body moves s metres in a time t seconds so that s = t3 – 3t2 + 8. Find:
Lady bird [3.3K]

Using derivatives, it is found that:

i) v(t) = 3t^2 - 6t

ii) 9 m/s.

iii) a(t) = 6t - 6

iv) 6 m/s².

v) 1 second.

<h3>What is the role of derivatives in the relation between acceleration, velocity and position?</h3>
  • The velocity is the derivative of the position.
  • The acceleration is the derivative of the velocity.

In this problem, the position is:

s(t) = t^3 - 3t^2 + 8

item i:

Velocity is the <u>derivative of the position</u>, hence:

v(t) = 3t^2 - 6t

Item ii:

v(3) = 3(3)^2 - 6(3) = 27 - 18 = 9

The speed is of 9 m/s.

Item iii:

Derivative of the velocity, hence:

a(t) = 6t - 6

Item iv:

a(2) = 6(2) - 6 = 6

The acceleration is of 6 m/s².

Item v:

t for which a(t) = 0, hence:

6t - 6 = 0

6t = 6

t = \frac{6}{6}

t = 1

Hence 1 second.
