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:

The measurement of x is 3.9999
Answer:
answer = 12.87 km/h
Step-by-step explanation:
Given
Ship A is sailing east at 25 km/h =
ship B is sailing north at 20 km/h =
here x and y are the sailing at t = 4 : 00 pm for ship A and B respectively
so we get x = 4 ×25 =100 km/h
y = 4× 20 = 80 km/h
let z is the distance between the ships, we need to find at t = 4 hr
At noon, ship A is 130 km west of ship B (12:00 pm)
so equation will be
derivative first equation w . r. to t we get
Answer:
C (- 4, - 2 )
Step-by-step explanation:
(c)
the x- coordinate of A is - 4
the y- coordinate of B is - 2
coordinates of C = (- 4, - 2 )
