Answer:
Day 0 , A = 150
Day 1 , A = 106.06
Day 2, A = 75
Day 3, A = 53.033
Day 4, A = 37.5
Step-by-step explanation:
The complete question is attached below
The exponential decay for area is depicted by
------Eq (1)
Substituting the values given in the attachment, we get -
On solving for lambda we get -
Substituting the value of lambda in equation 1 we get -
Substituting the value of d one by one we get
Day 0 , A = 150
Day 1 , A = 106.06
Day 2, A = 75
Day 3, A = 53.033
Day 4, A = 37.5
I think its what evr i just need points
A.) graph of two lines that intersect at the point negative 1, 1, with text on graph that reads One Solution negative 1, 1
Step-by-step explanation:
The two simultaneous equation given are;
y+2x= -1
3y-x=4
multiply the first equation by 1 and the second equation by 2 to make the terms with x equal
y+2x = -1
6y-2x=8
-------------- ---add the terms with x to eliminate x
7y=7 -------divide both sides by 7 to remain with y
7y/7 =7/7
y= 1 -----use the value of y in the first equation
y+2x= -1
1+2x= -1
2x= -2
2x/2= -2/2
x= -1
The solution is (-1,1)
You can plot the equations on a graph tool as shown below to visualize the solution where the two linear equations intersect

Well for question 1 if 0.5 cm is 7 km then 1 cm would be 14 km so I multiplied it by 5 cm x 14 km and got the answer of B. 70 km. Also for question 2 I can’t really explain how I didn’t my work cause it would make this text longer but I think the answer is A. 900/150 = 3/w
