Answer:
Step-by-step explanation:
Given the exponential function:
P(t) = 500,000 * e^(-0.099t)
P(t) = population t years later
When population will be one-half the initial amount
Half the initial amount = 500000/2 = 250,000
250000 = 500000 * e^(-0.099t)
250000/50000 = e^(-0.099t)
0.5 = e^(-0.099t)
Take the In of both sides
In(0.5) = - 0.099t
−0.693147 = - 0.099t
0.693147 / 0.099 = t
t =
Answer:
65.2
Step-by-step explanation:
the two is the tenth and your not adding any thing because the 4 is less than five
The current quiz grade average of Malika using subtraction expression is 15/4.
- Subtraction is that the operation of taking the distinction of 2 numbers and . Here, is named the number and therefore the image between the and is named the sign. The expression " " is scan " minus ."
We have given the average points of Malika 4¹/₂ which on simplifying gives 4¹/₂ = 4 ×2 +1 / 2
= 8 +1 / 2
= 9/2
It is also given that at the end of the quarter, his average decreases by 3/4 point which can be represented by
Current quiz grade average = 9/2 - 3/4
= 18 - 3 / 4
= 15 /4

2000 x 120kg = 240000kg altogether
Answer:
//Solve equation [2] for the variable y
[2] y = 4
// Plug this in for variable y in equation [1]
[1] (4) - x = -2
[1] - x = -6
// Plug this in for variable y in equation [4]
[4] (4) - 2x = 1
[4] - 2x = -3
// Solve equation [1] for the variable x
[1] x = 6
// Plug this in for variable x in equation [3]
[3] (6) = 3
[3] 0 = -3 => NO solution
No solution
