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.
Answer:
= 2.8
Step-by-step explanation:
If the quadrilaterals are similar, then the ratios of corresponding sides will be equal:
KL : QR = 4 : 5.6 = 4 / 5.6 = 5/7
JM : PS = 7 : 9.8 = 7 / 9.8 = 5/7
LM : RS = 3 : 4.2 = 3 / 4.2 = 5/7
This shows that the ratio of KJ : QP = 5/7
KJ : QP = 2 : = 2 /
Therefore,
cross multiply: 14 = 5
Divide both sides by 5: = 2.8
