Algebra 2 ; question in the attached

has 5 real and 0 non-real zeroes.

Step-by-step explanation:

Here, the given polynomial is

Now, by FUNDAMENTAL THEOREM OF ALGEBRA:

A polynomial of  degree n can have at most n roots.

So, here the number of roots f(x) can have = 5

Now, examine the change in the sign of f(x) and f(-x)

Signs of f(x) is  + - -.

So for f(x)  the sign changes only once.

Now,  

or,  

Here, signs are - - -

So,for f(-x)   the SIGNS DO NOT CHANGE.

So it has no negative real zero.

Hence, has 5 real and 0 non-real zeroes.

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
