Answer:
a = 9, b = 3
Step-by-step explanation:
The exponential function is
y = a 
Find a and b by using the points it passes through
Using (0, 9 ) then
9 = a
(
= 1 )
a = 9
y = 9 
Using (3, 243 ) then
243 = 9b³ ( divide both sides by 9 )
27 = b³ ( take the cube root of both sides )
b =
= 3
y = 9
← exponential equation
Answer:
50% off
Step-by-step explanation:
15 is half of 30 so it would be 50%
Answer:
9,216π or 28,938.2 meters³
Step-by-step explanation:
Given: diameter 48 inches
Radius 24 inches
Note:
Volume of hemisphere = volume of sphere / 2
Volume of hemisphere = 1/2 • 4/3 • πr³
= 1/2• 4/3×π×24³
= 1/2•18432π
= 9,216π
= 28,938.2 meters³
Assuming g is the centroid, it is 2/3 of the length of cf from point c.
cg = (2/3)cf = (2/3)3.6 m
cg = 2.4 m
