Answer:
y= 1200(0.92)^x
Step-by-step explanation:
Given data
Cost price= $1200
Rate of decrease= 8%
Let the time be x
The expression that describes an exponential function is
y= ab^x
for decrease b= 1-r
y= 1200(1-0.08)^x
y= 1200(0.92)^x
Hence the expression is
y= 1200(0.92)^x
Obtuse. 1: acute angle a small angle. 2: obtuse is a larger angle. 3: straight is ———— that
Answer:
x=5/3log(3) -1
x=2.949317
Step-by-step explanation:
reorder terms
3log(3)x(x+1)+5
distribute 3log(3)
3log(3)x+3(log)=5
Move constant to the right
3log(3)x=5-3log(3)
Divide both sides by 3log(3)
x=5/3log(3) -1
Solve 3log(3)
3log(3)= 3.949317
3.949317-1=2.949317
