Find the period. Principal = 5300=5300equals, 5300 rupees
Annual rate of interest = 6.5 \%=6.5%equals, 6, point, 5, percent
Total amount = 6678=6678equals, 6678 rupees

i believe that the slope of the line is -5

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
