Answer:
The exponential function best models the data for the given table.
Step-by-step explanation:
Given : The table showing the estimated number of bees, y, in a hive x days after a pesticide is released near the hive.
We have to find which function best models the data for the given table.
Consider the given data in the table.
We first plot the data using Expo- regression calculator (as shown in attachment)
Since, The the estimate number of bees deceases with increasing number of days ,thus the data represents an exponential decay over time.
Thus, The exponential function best models the data for the given table.
And the equation of model is given as 
Where y represents the estimate number of bees
and x represents the number of days.
Step-by-step explanation:
Given p = 4,
substitute p= 4 into the expression
6p+4/7+5p-6/2-3p/4

Answer:
Nonstop ride is 12 hours long.
Explanation:
With stopping time taken by train = 18 hours.
Without stopping time is reduced by 1/3.
Time for non stop ride = Time for stopping ride - (Time for stopping ride/3)
= 2 x Time for stopping ride/3
= 2 x 18 /3 = 12 hours.
So, nonstop ride is 12 hours long.
Answer:
x=435 ,y=145
Step-by-step explanation:
You substitute x for 3y in this equation and get
3y+y=580
from here you simplify
4y=580
and divide 580 by 4 to get what y is
y=580/4
y=145
now since x=3y you mutiply y by 3
x=3(y)
x=3(145)
x=435
