I cant see the whole question
2 because that’s how the equation is
Answer: Solved.
Step-by-step explanation: The calculations are as follows -
(12) Given zeroes are 5, -3 and -1 + 3i. So, the other conjugate of -1 + 3i, i.e., -1 - 3i will also be a root of the polynomial. So the polynomial f(x) will be of degree 4 and is given by
(13) Given polynomial is
Now, we will substitute the rational numbers in place of 'x' and check whether the value of f(x) becomes zero or not.
We will see that
Also, the polynomial is not zero for any rational number.
(14) Given,
So,
Thus, the problems are solved.
Answer:
Step-by-step explanation:
You used Pythagorean theroem which is correct as this does form a right triangle however 50 is the hypotenuse as the ladder is propped up against the wall. 30 would then be the height of the triangle and the base is unknown so...
50 squared minus thirty squared gives 1600 so:
Therefore x is the square root of 1600 which is 40
Since there is a total of 17 pens and 2 are removed then there is 15 left. the probability is 5/17 on the first draw and 4/16 (simplified is 1/4) on the second draw.
