Which pair of values could NOT be the roots of a quadratic polynomial?
A) 4 and 6
B) 5 and 5
C) 2 + 3i and 2 + 3i
D) 1 + 3i and 1 –3i
Answers
Answer:
Part c
Step-by-step explanation:
In quadratic equations of real coefficients, the complex roots always occur in conjugate bases. It means, if, 2 + 3i is one of the roots and then the second root must be 2 - 3i.
The pair of values that can not be the roots of a quadratic polynomial is 2 + 3i and 2 + 3i
A polynomial is an expression consisting of the operations of addition, subtraction, multiplication of variables.
Polynomials can be classified based on degree as linear, quadratic, cubic, etc.
If the root of a quadratic polynomial is a complex number, then it must be in conjugate pairs.

Step-by-step explanation:
Point N is the vertex of angle 1. Therefore, we can give <1 another name by using 3 letters which includes the letter of vertex point in the middle, and two other letters of the two rays that meets at the vertex point.
Thus, JN and LN meets at point N. Therefore angle 1 can be named as:

lim x→π/2 1-sinx/cot^2x
any genious help please
Answers
Rewrite the limand as
(1 - sin(x)) / cot²(x) = (1 - sin(x)) / (cos²(x) / sin²(x))
… = ((1 - sin(x)) sin²(x)) / cos²(x)
Recall the Pythagorean identity,
sin²(x) + cos²(x) = 1
Then
(1 - sin(x)) / cot²(x) = ((1 - sin(x)) sin²(x)) / (1 - sin²(x))
Factorize the denominator; it's a difference of squares, so
1 - sin²(x) = (1 - sin(x)) (1 + sin(x))
Cancel the common factor of 1 - sin(x) in the numerator and denominator:
(1 - sin(x)) / cot²(x) = sin²(x) / (1 + sin(x))
Now the limand is continuous at x = π/2, so
[tex]\displaystyle\lim_{x\to\frac\pi2}\frac{1-\sin(x)}{\cot^2(x)}=\lim_{x\to\frac\pi2}\frac{\sin^2(x)}{1+\sin(x)}=\frac{\sin^2\left(\frac\pi2\right)}{1+\sin\left(\frac\pi2\right)}=\boxed{\frac12}[/tex]

At 12:45 Jimmy left his home in Pinetrees and cycled to visit his grandmother in Oakville. On his
way he stopped for 10 minutes in Rowan for a coffee and then he popped in to see his friend in
Yewton. He arrived in Oakville at 16:25. Jimmy cycled at a steady speed of 24 km/h and his
average speed for the whole journey, including the stops, was 18 km/h.
For how long did Jimmy stop in Yewton?
А
40 minutes
B
45 minutes
C
55 minutes
D
60 minutes
Answers
t=45min
d=4km
45min/60min = 0.75 hours
v=d/t
v=4km/0.75hours
v=5.33km/hour. So the answer is B. 45 minutes.
Jimmy stopped in Yewton for 45 minutes if Jimmy cycled at a steady speed of 24 km/h and his average speed for the whole journey, including the stops, was 18 km/h.
What is the distance?Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
It is given that:
At 12:45 Jimmy left his home in Pinetrees and cycled to visit his grandmother in Oakville.
Let x be the total time Jimmy stops in Yewton:
Total time for the journey = 220 minutes (12:45 to 16:25)
As we know:
distance = speed×time
24(220 - 10 - x) = 18(220)
220 - 10 - x = 165
x = 210 - 165
x = 45 minutes
Thus, Jimmy stop in Yewton for 45 minutes if Jimmy cycled at a steady speed of 24 km/h and his average speed for the whole journey, including the stops, was 18 km/h.

What is the area of a circular region whose
diameter is 12 centimeters?
Answers
Answer:
A circle of radius = 12 or diameter = 24 or circumference = 75.4 cm has an area of: 4.524 × 10-8 square kilometers (km²)
The area of the circular region will be 113 square centimeters.
What is an area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.
The formula to calculate the area of the circle is given by:-
A = πr²
Given that the diameter of the circular region is 12 centimeters. The radius will be half of the diameter.
r = d / 2
r = 12 / 2 = 6
The area of the region will be calculated as below:-
A = πr²
A = π x ( 6 ) x ( 6 )
A = 113.09 square centimeters
Therefore, the area of the circular region will be 113 square centimeters.

4. What is the circumference of a circle whose area is 81π cm squared?
Answers
Circumference = 2pi*r
Step 1: find the radius from area
81pi=pi*r^2
81=r^2
9=r
Step 2: plug in radius to the circumference equation
Circumference = 2pi*r
18pi is the answer, otherwise know as 56.52 as well.
Step-by-step explanation:
Let us assume R be the radius of circle We know that, area of circle = πR2 81πr2 = πR2 R = √81 r R = 9r Circumference = 2 πr = 2 π (9r) = 18πr
