Answer:
Step-by-step explanation:
We are given the following in the question:
We have to find the derivative of the given expression.
<h2>Answer: 297</h2>
<h3>Step-by-step explanation:</h3>
Based on the 4 terms given in the sequence, we can determine the rule to be: 6n - 3
1s term: 6(1) - 3 = 3
2nd: 6(2) - 3 = 9
3rd: 6(3) - 3 = 15
4th: 6(4) - 3 = 21
<h3> ∴ 50th term = 6(50) - 3 = 297</h3>
-0.48 + 1 (2/5 = 0.4)
-0.48 + 1.4 = 1.88
Step-by-step explanation:
We khow the sum and the product of the zeroes of this quadratic polynomial
Here is a trick :
when we khow the sum S and the product P ofvtwo numbers we can find them by solving :
x²-Sx+p=0
here S= -8 and P=12
so:
x²+8x+12=0
Let Δ be the discrminant of this equation: a= 1 , b= 8 and c=12
Δ= 8²-4*12 =16
the zeros are:
(-8-4)/2= -6
(-8+4)/2 = -2
verify:
-6+(-2)= -8
-2*(-6)= 12
now the polynomial quadratic is:
(x+6)(x+2)
