A fish population grew according to the following quadratic model, the number of fish a day is given by P(t)=800t-t^2

What is the initial growth rate a t=0

800 fish per day is the initial growth rate of the fish population

Step-by-step explanation:

The growth rate is the derivative of the population function with respect to time (t). Therefore, we need to calculate the derivative of P(t) and evaluate it at t=0:

which evaluated at t = 0 becomes:

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
