Answer:
Step-by-step explanation:
First convert them into improper fractions: 
and 
. Now we add: 
or 
.
The equation given in the question is
- 3 1/3 = 1/2g
- 10/3 = 1/2g
- (10 * 2g) = 1 * 3
- 20g = 3
- g = 3/20
g = - (3/20)
So
the value of g that has been deduced is -(3/20). This is the easiest
procedure to get to the solution of the question gives. Based on the
above procedure, similar problems can be easily solved without any error
or issue. I hope this solution has helped you.
Answer:
Step-by-step explanation:
The exponential decrease formula that we must use is:
Where A is the amount of thorium as a function of time
is the initial amount and k is the decrease rate
We know that initially there are 50 gr and that you decay 50% every 1.9 years.
So
We solve the equation for k
After 22.8 years the amount of thorium that exists is:
The rule that describes the composition of transformations that maps ΔJKL to ΔJ"K"L" is Rotation 0° to 90° and reflection about the x-axis.
<h3>What is the transformations rule that was used here?</h3>
A transformation is a rule that is used to manipulate the position of a point of geometric figure.
Analyzing the figure, rotation of ΔJKL through the angle 90 degrees in a counter-clockwise direction gives us ΔJ'K'L' .
ΔJ"K"L" is been gotten also using ΔJ'K'L' through the refraction of ΔJ'K'L' across the x-axis.
In this case, rule that describes the composition of transformations that maps ΔJKL to ΔJ"K"L" is Rotation 0° to 90° and reflection about the x-axis.
