Step-by-step explanation:
<u>Exponential Growth Function
</u>
The exponential function is commonly used to model natural growing or decaying processes where the change is proportional to the actual quantity.
An exponential growth function is expressed as:
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the growth positive rate, expressed in decimal
Nicki paid Co=$245,000 for a house and it's known that home prices increase by r=3.5%=0.035 each year.
a)
Substituting the given values, the equation is:
b) The value of Nicki's house in t=4 years is:
Nicki's house is worth $281,143 in 4 years
Step-by-step explanation:
CD = 6 cm because opposite sides are equal
angle d = 110
Answer:
All positive rational numbers greater than 50
Step-by-step explanation:
Since the delivery cost is fixed per trip, the cost incurred can be represented by the equation
y(x)=8x+50 so in case Tess wants only 1 tone, the cost will be y(x)=8(1)+50=58
Therefore, it's proper to conclude that all numbers in the possible range are positive rational numbers greater than 50
Let Isaac = x
Ruby = x + 4
Svetlana = 4(x + 4)
Together they worked 104 hours, so...
x + x + 4 + 4(x + 4)= 104
x + x + 4 + 4x + 16 = 104
6x + 20= 104
6x = 84
x = 84/6 = 14
Isaac worked x = 14 hours
Ruby worked x + 4 = 18 hours
Svetlana worked 4(x + 4) = 4×18 = 72 hours
Check your answers...
72 + 18 + 14 = 104
104 = 104 it checks!
Answer:
x = 20
4x = 80
5x = 100
Step-by-step explanation:
5x + 4x + 5x + 4x = 360
18x = 360
x = 20
