If a+b = 10 and ab= 16 . Find the value of a^2 - ab + b^2
Answers
Answer:
(a+b)^2=a^2+2ab+b^2
The given expression is that -3ab
100-3*16=100-48=52
52 it is.

Graph of function f of x is a curve which joins the ordered pair 0, 1 and 1, 2 and 3, 10 and 5, 26 and 6, 37 f(x), because an increasing quadratic function will eventually exceed an increasing exponential function g(x), because an increasing exponential function will eventually exceed an increasing quadratic function f(x), because an increasing exponential function will always exceeds an increasing quadratic function until their graphs intersect g(x), because an increasing quadratic function will always exceeds an increasing exponential function until their graphs intersect

x = 100%
20x = 14 . 100
20x = 1400
x = 1400
20
x = 70
S = 20% of 70 is 14.
20 percent of 70 number is 14.
Here we have to find,
The number of which 20 percent is 14
Le the number = x
Now divide 20 by 100
20% = 20/100
= 0.20
Now multiply 0.20 with x we get,
⇒ 0.20x
Now equate it tp 14 we get,
⇒ 0.20x = 14
⇒ x = 14/0.20
= 70
Hence,
The number is 70.

The new average will be 89.55%.
What is an average?
The average is defined as the mean value which is equal to the ratio of the sum of the number of a given set of values to the total number of values present in the set.
It is given that,
Average score after 8 tests = 91%.
Therefore, Total score of 8 tests = Average score*Number of tests
Total score of 8 tests = 91*8
Total score of 8 tests = 728
Now, Cory scored 78% in 9th test,
So, Total score of 9 tests = Total score of 8 tests + 78
Total score of 9 tests = 728 + 78
Total score of 9 tests = 806
Hence, Average score of 9 test = Total score of 9 tests/9
Average score of 9 test = 806/9
⇒ Average score of 9 test = 89.55%
Hence, the new average will be 89.55%.

Then add on his latest test result 728+78 = 806
Now divide by the number of tests (9) 806/9 = 89.55555555
