Answer:
The area after 9 years will be 1,234 km^2
Step-by-step explanation:
In this question, we are tasked with calculating what the area of a certain forest that decreases at a certain percentage would be after some years.
To answer this question, we shall be using an exponential approximation.
Now, to use this exponential approximation, we shall be needing a supporting exponential mathematical equation.
This can be written as;
A = I(1-r)^t
where A is the new area we are looking for
I is the initial area which is 1700 according to the question
r is the rate of decrease which is 3.5% = 3.5/100 = 0.035
t is time which is 9 years according to the question
We plug these values and have the following;
A = 1700(1-0.035)^9
A = 1700(0.965)^9
A = 1,233.66
This is 1,234 km^2 to the nearest square kilometer
Answer:
$9.61 per shirt
Step-by-step explanation:
You take the total cost of $48.05 and divide it by the number of t-shirts which is 5.
48.05/5 = 9.61
The values of OM, PN, ON and MN of the given square are;
OM = 46
PN = 23
ON = 32.5
MN = 32.5
<h3>Pythagorean theorem</h3>
We are given;
LN = 46
- Now, LN is the diagonal of the square and as such to get the sides of the square, we will make use of pythagoras theorem to get;
LO² + ON² = 46²
Since LO = ON, then;
2LO² = 46²
LO² = 46²/2
LO = √1058
LO = 32.5
Thus;
LO = ON = MN = 32.5
For the diagonals;
LN = OM = 46
Also; LP = PN = 46/2 = 23

Answer:
Area of Triangle QRP = 3
Step-by-step explanation:
According to Question , We have a circle With Centre 'O' & Area 48
.
Area Of Circle = 48
= 48
r = 
Now We Have Two Points Given On Circle Q & R , P Is Circumcentre Of Triangle QRO .
Thus A Circle Can Also Be Formed with Centre P . ( See attachment For Diagram )
Now The Diameter of Circle With Centre P = Radius Of Circle with Centre O
so Radius Of Circle With Centre P(
) = 
Now We Have To Find Area Of Equilateral Triangle .
A = 
A= 
The Area Of PQR is = 3
