Which of the digits are underlined ?
if it’s the first 7 it’s 7 ones
if it’s the 2 it’s 2 tenths
if it’s the last 7 it’s 7 hundredths
I think the formula for the volume of a cone is V=(1/3) x hπr².
r²= 9
1/3= 0.3
= 0.3 x 4 x 3.14 x 9
= 33.912
49.5-40 = 9.5
so 40 x 8.18 = 327.20
8.18 x 1.5 = 12.27
12.27 x 9.5 = 116.57
327.20 + 116.57 = $443.77
So we are given the equation
y = 79.31(1.48)ˣ
Whereas the x represents the number of days <--- what you need to know
y is the final number you are going to get, does not matter for now
You are trying to find the number of bacteria on Day 8
Put 8 into x
