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
The answer is 27.533333333..
Answer:
x= 45
Step-by-step explanation:
angle EOB = 90 degrees so angle EOA must also be 90 degrees. Divide 90 by 2 = 45. You can figure out the rest from now on.
Answer:
The distance between harbor & the island D = 72.12 km
Step-by-step explanation:
Let the total distance between harbor & island = D
Motor boat going to the island at speed 
= 13 knots = 24 
Return speed of the motorboat 
= 10 knots = 18.52
The total time taken for both journey = 6.9 hours
D ( 0.0956 ) = 6.9
⇒ D = 72.12 km
This is the distance between harbor & the island.
