Let the water surface be 0.
He starts at 15 and gets to the water surface of 0 so he travels 15 meters.
He then goes 5 meters below the surface.
15 + 5 = 20 total meters.
Hello!

Recall that the equation of an exponential graph is:

We can see from the graph there is a y-intercept at y = 5. Plugging in 0 for x results in:

Solve for b by plugging in another point on the graph:

Write the final equation:

Answer:
The total monthly mortgage payment for the house is $975.63
Step-by-step explanation:
The principle amount is $175000
80% of 175000 is =
= $140000
20% of 175000 is =
= $35000
Emi formula is :

For 1st part:
p = 140000
r = 4.75/12/100=0.00395
n = 
Putting values in formula we get

= $729.508
For 2nd part:
p = 35000
r = 7.525/12/100=0.00627
n = 
Putting values in formula we get

= $245.301
Adding both the monthly payments:
dollars
This is closest to option A.
So, option A is the answer.
And for 30 years the mortgage payment will be =
dollars
Answer:
45000000000
Step-by-step explanation:
when multiplying exponents, you multiply base numbers with no exponent (9 and five in this case) and numbers with exponents (10 in this case). 9 X 5 is 45 and 10 to the power of 7 times 10 to the power of 2 is 10 to the power of 9 or 1000000000. 45 X 1000000000 is 45000000000.
