Answer:
0.16 gallons of paint are used on each piece of furniture.
The answer lies between the whole numbers 0 and 1.
Step-by-step explanation:
we know that
Four gallons of paint are used to paint 20 chairs and 5 small tables.
if each chair and table used the same amount of paint
then
sum the total pieces of furniture
20+5=25 pieces
Find the unit rate
Divide the total gallons of paint used by the total pieces
therefore
0.16 gallons of paint are used on each piece of furniture.
The answer lies between the whole numbers 0 and 1.
Answer:
Step-by-step explanation:
exponential function :
where a = y intercept and b = factor ( what you multiply by )
looking at the table the y intercept is at (0,10) so a = 10
so we now have y = 10 * (b)^x
to find the factor we simply plug in one of the ordered pairs.
note that the ordered pair chosen does not effect the outcome
i chose (2,250)
we have y = 10 * (b)^x
(x,y) = (2,250)
250 = 10 * (b)^2
divide both sides by 10
25 = b^2
take the square root of both sides
5 = b
the final equation would be f(x) = 10 * (b)^x
