Answer: <em>D) </em><u><em>He cannot construct a triangle</em></u>
Step-by-step explanation:
For a triangle to be possible <u>the largest side must be less than the sum of other two sides .</u>
In the given question largest side is 23 while other two sides are 8 and 14
Therefore for triangle to be possible 23 should be less than (8+14) but 23 > (8+14) .
Thus he can not construct a triangle using the given sides.
Hence correct option is <u><em>D)He cannot construct a triangle.</em></u>
Answer:
Step-by-step explanation:
we are given an algebraic function in x, such that
To find when second derivative >0
For this let us find first and second derivative by successive differentiation.
when ii derivative >0 we have
60x^3-30>0
f"(x)>0 in
Example 1. Let us start with the functionf(x) = x2. We have

So

which means f '(a) = 2a.
What about the derivative of f(x) = xn. Similar calculations, using the binomial expansion for (x+y)n (Pascal's Triangle), yield

4(4x + 6) - 7 = 77 - 4x......distribute thru the parenthesis
16x + 24 - 7 = 77 - 4x ...simplify
16x + 17 = 77 - 4x ...addition property of equality....add 4x to both sides
16x + 4x + 17 = 77 ...subtraction property ...subtract 17 from both sides
16x + 4x = 77 - 17...combine like terms
20x = 60 ....division property....divide both sides by 20
x = 60/20
x = 3
