Answer/Step-by-step explanation:
Two figures can only be similar if their corresponding lengths are proportional to each other, that is the ratio of their corresponding sides are equal.
AB corresponds to HI.
AB = 2 units, HI = 1 units.
AB : HI = 2/1 = 2
The ratio of all the sides of ABCDEFG are equal to the corresponding sides of HIJKLMN, which is 2, EXCEPT for side FG which corresponds to MN.
FG = 1 units
MN = 1 units.
FG : MN = 1/1 = 1
This ratio is different from what we have for the ratio of the other corresponding sides of both figures.
Therefore, the figures are not similar.
Answer:
add x
Step-by-step explanation:
1)sx*tx
2)sx+tx
3)s-t
In realistic world there are so many examples which use exponential and logarithmic functions.
Use of Logarithmic function
We can find use of logarithmic function in measuring earthquake (Richter Scale) , the brightness of stars , and chemistry(pH balance , measure of acidity and alkalinity)
For example:
In Richter Scale , a logarithmic function that is used to measure the magnitude of earthquake.
If A = measure of amplitude of earthquake wave.
= Amplitude of smallest detectable wave.
From this we can find R the Richter scale measure of magnitude of earthquake.
Use of Exponential Function:Exponential function may use in finding compound interest , population growth , radioactivity decay , etc.
For example :
As we know the formula for compound interest is
Where P is principal amount , r = rate of interest(decimal) , n is the number of compounding period , t is time.

Answer: 0
Step-by-step explanation:
56 + (-56) is the same as 56 - 56 which equals zero
