12. Currently, there are 350 students in the seventh grade at Winchester
sweet [91]

Answer:

Winchester Heights Middle School plan to have 385 students in the  upcoming school year.

Step-by-step explanation:

Total number of students in the seventh grade at Winchester  Heights Middle School = 350

For the upcoming school year, they are planning to  increase the number of seventh graders by 10%.

Rate of increase = r = 10% = 0.1

Formula :N(t)=N_0(1+r)^t

Where N_0= initial population = 350

r = rate of increase =0.1

N(t)=Population after t years

t = time in years

So, Population after 1 year = 350(1+0.1)^1 =385

Hence  Winchester Heights Middle School plan to have 385 students in the  upcoming school year.

Which equation could represent p? Please please help
Andre45 [30]

Answer:

<h2>P(x) = (x+3)(x-2)^2</h2>

Step-by-step explanation:

Looking at the brackets you can see where the curve will intersect the x-axis.

The graph shows the curve intersecting at (0,-3) and (0,2).

This means:

x = -3

AND

x = 2

Rearrange the equations, equating them to 0.

x + 3 = 0

x - 2 = 0

This will be the values in the brackets.

Because the curve only touches 0,2 and DOES NOT cross it, we know that x - 2 is a repeated root, hence (x-2) is squared.

Therefore your brackets are: (x+3)(x-2)(x-2)

Which can be simplified:

(x+3)(x-2)^2

Where ^2 means squared.
