Answer:
it's either a or b, but I would go with A
The change is decay and the percentage rate of decrease will be 95%.
An exponential function is a function where a number is raised to the variable i.e. base is raised to the exponent times.
Here given the exponential function is y= 4300(0.042)ˣ
Now we have to identify if the change in exponential function represents growth or decay, and have to determine the percentage rate of increase or decrease.
Here in the exponential function, the base is less than 1 so the change is decay.
The equation represents exponential decay because the decay factor is lesser than 1.
The general form of the exponential equation is:
y(x)= a(1-r)ˣ such that r is the decay.
equating with the equation
y= 4300(0.042)ˣ
a= 4300
and 1-r=0.042
⇒r= 1-0.042
⇒r= 0.958
the perecentage of decay will be r*100= 0.958*100= 95%
Therefore the change is decay and the percentage rate of decrease will be 95%.

#SPJ10
Answer:
hope it is helpful
Step-by-step explanation:
10 is the increase in number
orignal vale is 20
so
increase %=increase in orignal value/orignal value ×100
=10/20×100=50%
Answer:
1+2+3+4+5+...+=1/12
Step-by-step explanation:
ANSWER IS 12
Answer:
(10, 0)
Step-by-step explanation:
(10, 0) satisfies both of the system equations: 2(10) + 0 = 20 and 4(10) - 0 = 40.
(0, 10) does not.
(4, 2) does not.
(10, -10) does not.
