N = 10(2)^t where N = number of bacteria and t = time in multiples of 3 hours
So when t = 24/3 we have
N = 10 (2)^8 = 2560 answer
When the 14 foot ladder is leaning against a building, which is vertical as shown in the attached graph, with 45 degree angle. If we use the sin equation for this problem we can find out the answer.
Sin 45 = X / 14
X = 14 * sin45
X = 9.9 foot
Therefore ladder will reach to 9.9 foot height in the building
V = 30*16*12. To find the volume of a rectangular prism, you just multiply the area of the base (side 1 * side 2) by the height of the prism.
