Answer:
4 seconds to reach 200 feet
Step-by-step explanation:
You can use Desmos (graphing calculator) then plug in the equation and you will find the x-values are 7.188 and 0- the origin.
Divide 7.188 by 2 (this is also solving for the midpoint/axis of symmetry) and you get 3.594
Round 3.594 to the nearest second which would be 4 seconds.
Hope that helps and have a great day!
Answer:
173.33333333333...
Step-by-step explanation:
4/3=1.3333333...
So 130×1.3333333... is 173.3333333...
To model this situation, we are going to use the exponential function:

where

is the initial number of cars

is the growing rate in decimal form

is number of tames the growing rate is increasing per year

is the time in years
To convert the growing rate to decimal form, we are going to divide the rate by 100%


Since the growing rate is increasing quarterly,

. We also know that the initial number of cars is 920, so

. Lets replace all those values in our function:



We can conclude that:
Rate ---------> The quarterly rate of growth is 0.03 or 3%
Exponent --------> The compound periods multiplied by the number of years is 4t
Coefficient--------> The initial number of cars serviced is 920
Base------> The growth factor is represented by 1.03
Answer:
800 artículos.
Step-by-step explanation:
Sea x = la cantidad de artículos vendidos
De la pregunta,
Precio de costo = 60 x + 4000
Venta (precio de venta) = 80x
También nos dieron ganancias como S12000
Para determinar la ganancia
Precio de venta: precio de costo = beneficio (cuando el precio de venta es más alto que el precio de costo)
Por lo tanto,
12,000 = 80x - (60x + 4000)
12,000 = 80x - 60x - 4000
Recolectando términos similares
12,000 + 4,000 = 80x - 60x
16,000 = 20x
x = 16,000 / 20
x = 800
Por lo tanto, la cantidad de artículos que se venderán si desea obtener una ganancia de S12,000 es de 800 artículos.
