Step-by-step explanation:
<u>Exponential Function</u>
The exponential function can be written with the general equation:
Where A is the value when x=0 and r>0 is the ratio. If r is greater than 1, the function is increasing, if r is less than 1, the function is decreasing.
The table shows the relation between values of x and values of the function y. Note that as x increases (one by one), y decreases with a ratio of 1/2. Only the last two choices have ratios of r=1/2. We only have to test which one of them has the correct value of y=4 when x=0.
Substituting in the third function:
This gives the correct value of f(0)=4.
Substituting in the fourth function:
This choice is wrong
Correct choice:

Answer:
The percentage loss = 10.9375 %
Step-by-step explanation:
Let the cost price = x
Since the marked price is 18.75% above the cost price so the
Marked price = 1.1875 x
When a discount of 25% is allowed on the marked price , the selling price will be Rs. 1425
⇒ Marked price × 0.75 = 1425
⇒ Cost price × ( 1.1875 × 0.75 ) = 1425
⇒ Cost price × ( 0.890625 ) = 1425
⇒ Cost price = 1600
Selling price = 1425
So percentage loss = × 100
% Loss = × 100
% Loss = 10.9375 %
<span>We have to find the volume of the sphere that has a radius of 9.6 m. The formula for the volume of the sphere is: V = 4/3 r^3 Pi. ( r = 9.6 m, Pi = 3.14 ) V = 4/3 * 9.6^3 * 3.14; V = 4/3 * 884.736 * 3.14; V = 3,705.97349m^3 ( when the number Pi is more accurate ). Answer: The exact volume of the sphere is 3,704.97349 m^3.</span>
