Answer:
Three zeros 
x-intercepts: (-4,0), (1,0), (6,0)
Step-by-step explanation:
Plot the graph of the function
on the coordinate plane. This graph intersects the x-axis at three different points (see attached diagram):
This means
are zeros of the function 
Answer: (-0.3) + 0.9= 0.6
Step-by-step explanation:
Answer:
a)
b)d(t)=500t
c)
Step-by-step explanation:
d = Horizontal distance
s = the distance between the plane and the radar station
The horizontal distance (d), the one mile altitude, and s form a right triangle.
So, use Pythagoras theorem


a) 
(b) Express d as a function of the time t (in hours) that the plane has flown.

d(t)=500t
(c) Use composition to express s as a function of t.

using b

Answer:
For Sandra to save up and purchase the mp3 she must save additional $22.
Step-by-step explanation:
This problem requires us to understand the concerns of deficit/balance
Step one
We were told that mp3 cost $95
And Sandra has saved $73
Hence for her to purchase the mp3 she has to save up to $95 which is the benchmark price for the item
Step two :
Hence the amount of money to balance up is
=Cost of mp3- Sandra's savings
= $95-$73
=$22
