Scientists are studying a bacteria sample. The function f of x equals 256. 1.15 to the x. gives the number of bacteria in the sample at the end of x days. Which statement is the best interpretation of one of the values in this function?
Answer:
the number of bacteria increases at a rate of 15% each day
Step-by-step explanation:
Given the function :
f(x) = 256(1.15)^x
The function represents an exponential growth function ; comparing the equation with the general form of an exponential growth function :
f(x) = A(1 + r)^t
A = the initial value of the population, = 256
(1 + r),; r = growth rate
Therefore, to solve for r ;
1 + r = 1.15
r = 1.15 - 1 ; r = 0.15
Hence, growth rate = 0.15 = 0.15 * 100% = 15%
Hence, the number of bacteria increases at a rate of 15% each day
A castle has to be guarded 24 hours a day. Five knights are ordered to split each day's guard duty equally. How long will each knight spend on guard duty in one day? Record your answer in hours as a decimal.

Josh and Bradley each bought a carton of milk. Their cartons were the same except that Bradley's carton was taller than Josh's. Each boy drank 1/4 of his milk carton. Did the each drink the same amount of milk? Explain.
Answer:
No
Because Bradley's carton is taller than Josh's, Bradley would drink more milk.
Let us assume that Bradley carton has 100 quarts . If he drank 1/4, he would drink 25 quarts of milk. If Josh carton is 80 quarts full of milk, he would drink 20 quarts of milk. this example shows that they would not drink the same amount of milk
Step-by-step explanation:
A taller carton would contain more ounces of milk.

En una tienda en la que todo está rebajado el 20% he comprado una casaca por la que he pagado 160 soles. ¿Cuál era el precio antes de la rebaja?
Answer:
200 soles
Step-by-step explanation:
De la pregunta anterior, se nos da un descuento del 20%.
Por lo tanto, la fórmula para resolver la pregunta anterior es:
Precio nuevo = Precio inicial - (Porcentaje de descuento × Precio inicial)
De la pregunta anterior,
Precio nuevo = 160 soles
Precio inicial = x
Porcentaje de descuento = 20% = 0.2
Por eso:
160 = x - (20% x x)
160 = x - 0.2x
160 = 0.8 veces
Dividir ambos lados por 0.8
160 / 0.8 = 0.8 / 0.8
x = 160 / 0.8
x = 200 soles
Por lo tanto, el Precio Inicial que es el precio antes de la venta es de 200 soles.
