I think it’s A and it’s B at the most but still...A
That is an angle bisector.
It divides an angle in half
hope it helps
In general, the derivative of a single term Ax^(n) is A n x^(n-1) .
And the derivative of a sum of many terms is the sum of the derivatives
of the individual terms.
Using these two rules, the derivative (with respect to 'x') of the expression
in the question is . . .
<em> Y' = -21x² - 16x + 6</em>
You would have to multiply then subtract
30% is .30
Multiply 18.75 and .30
which is $5.63
Then subtract 18.75 from 5.63
Which the final ANSWER is: $13.12
Double of 50 is 100, so 28*100=2800, now half of the answer is 2800/2=1400
