It equals to:
(3(a+h)^2 - 3a^2) / h = 3(2ah+h^2) / h = 6a + 3h
Considering the volume of the cone, it is found that each triathlete sloshed out 9.5 cm³ of water.
<h3>What is the volume of a cone?</h3>
The volume of a cone of <u>radius r and height h</u> is given by:
V = 1/3 x r² x h
In this problem, the radius and the height are given as follows:
r = 3.5 cm, h = 7 cm.
Hence the total volume is:
V = 1/3 x 3.5² x 7 = 28.6 cm³
The triathletes sloshed out 1/3 of that, hence:
1/3 x 28.6 = 9.5 cm³.

Answer:

Step-by-step explanation:
Let points A, B and F have coordinates
and 
If BA is extended all the way through A creating BF and A becomes the midpoint of BF, then the midpoint A of the segment BF has coordinates:

Express coordinates of point F:

Hence,

Answer:
y-intercept (0,1)
multiplicative rate of change: b
Step-by-step explanation:
If a table represents an exponential function of the form
, then the y-value that corresponds to x=0 is 1.
In other words, the y-intercept (0,1) must be present in the table.
Also the ratio of a subsequent y-value to the previous y-value should give a value of b.
In other words the multiplicative rate of change from the table must be equal to b.
