Answer:
105 years
Step-by-step explanation:
Given the function :
Q(t) = 4e^(-0.00938t)
Q = Quantity in kilogram of an element in a storage unit after t years
how long will it be before the quantity is less than 1.5kg
Inputting Q = 1.5kg into the equation:
1.5 = 4e^(-0.00938t)
Divide both sides by 4
(1.5 / 4) = (4e^(-0.00938t) / 4)
0.375 = e^(-0.00938t)
Take the ln of both sides
In(0.375) = In(e^(-0.00938t))
−0.980829 = -0.00938t
Divide both sides by 0.00938
0.00938t / 0.00938 = 0.980829 /0.00938
t = 104.56599
When t = 104.56599 years , the quantity in kilogram of the element in storage will be exactly 1.5kg
Therefore, when t = 105 years, the quantity of element in storage will be less than 1.5kg

Answer:
The chart type described is the OHLC chart.
Step-by-step explanation:
An OHLC chart is a kind of bar-chart that displays open, high, low, and closing prices for each period. OHLC charts are beneficial since they demonstrates the four major data values over a period, with the closing price being reflected as the most significant by traders.
The chart type is valuable since it can represent increasing or decreasing movement. When the open and close are far-apart it represents strong movement, and when the open and close are close together it represents wavering or weak movement. The high and low displays the full price range of the period, useful in evaluating instability.
Thus, the chart type described is the OHLC chart.
Answer:
x= 2.25
Step-by-step explanation:
-3x +10= 5x -8
<em>Bring all x terms to 1 side, constants to the other:</em>
5x +3x= 10 +8
8x= 18
<em>Divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>8</em><em>:</em>
x= 18 ÷8
x= 2.25
∴ The value of x is 2.25 to make the equation to be true.
