Answer:
a=
15
b=1/3
Step-by-step explanation:
- key rule: see the graph carefully to get the following identified points.
- from the given graph, it can be seen that, the curve passes through (0,15)
- by substituting this point in y=a*(b)^x,
15=a*(b)^0
15=a
- it can also be seen that the curve passes through (1,5)
- by substituting this point in y=a*(b)^x,
5=a*b
5=15*b ( since, we have found that a=15 from the before steps)
- dividing both the sides by 15,
5/15=b=1/3
a=
15
b=1/3.
The rules of the calculation are:
- Round the result to the same number of significant figures as the value with the least number of significant figures
- Round up if the digit to be dropped is 5 or greater.

The equation is given as:
0.738 × 0.28 = 0.20664
When approximated, we have:
0.738 × 0.28 ≈ 0.21
The above approximation can mean any of the following:
- To 2 decimal places
- To the nearest hundredth
- To 2 significant digits

Actually the first answer is incorrect, it would be 83 1/3%. You solve this by dividing 5 by 6.
44
Assuming JM and LN are parallel, KMJ=MKN. MKN is part of a triangle where the other two values are defined (48 and 88). By subtracting these values from 180, we find the value of MKN is 44, which therefore is also the value of KMJ.
