Answer:
P(x) = 
Step-by-step explanation:
Root multiplicity of 2 means the root is repeated 2 times. Root multiplicity of 1 means root is repeated only once.
A polynomial of degree 3 means the largest exponent of x is 3.
Here, the polynomial P(x) has root 5 with multiplicity 2 and -5 with multiplicity 1.
So, P(x) = 
Where,
is a constant.
Now, it's given that the y intercept is -87.5. Therefore, value of x at y intercept is 0.
We obtain
by plugging in -87.5 for P(x) and 0 for x.


Therefore, the polynomial P(x) is given as:

Answer:
She can make 2 batches.
Step-by-step explanation:
Since she has 4/5 and only needs 2/5, she can make two batches. (2/5 is half of 4/5)
Multiply 3/4 and 4 and you simply get 3 (these are the amount of tickets bought) Then divide the cost by tickets which results in 2.05
(3/4) x 4=3
6.15 / 3 = 2.05
The equation in slope intercept form for the line with slope 3 and Y intercept -1 is y = 3x -1 .
The answer is 492.307
The number after the thousandths is 9 - greater than 5 - so we round 6 up to 7.
