Step-by-step explanation:
Exponential Functions:
y=ab^x
y=ab
x
a=\text{starting value = }1600
a=starting value = 1600
r=\text{rate = }5.25\% = 0.0525
r=rate = 5.25%=0.0525
\text{Exponential Growth:}
Exponential Growth:
b=1+r=1+0.0525=1.0525
b=1+r=1+0.0525=1.0525
\text{Write Exponential Function:}
Write Exponential Function:
y=1600(1.0525)^x
y=1600(1.0525)
x
Put it all together
\text{Plug in time for x:}
Plug in time for x:
y=1600(1.0525)^{25}
y=1600(1.0525)
25
y= 5750.0628984
y=5750.0628984
Evaluate
y\approx 5750.06
y≈5750.06
6.6, 7.2, 7.8 Hopefully I helped, if this was not what you were looking for tell me, I will try my best
9-16x^2
This is the answer pretty much the 3 is okay but once you see the four notice there’s - and + you’d multiply it
Compose an equation
2/5x=3/20
Then solve
8/20x=3/20
8x=3
x=3/8
I might be wrong
