The area, in square meters, of a pond covers by an algae bloom decreases exponentially after a treatment is applied

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

it goes right

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
