A duck dives underwater and its path is described by the quadratic function y = 2x^2 - 4x, where y represents the position of the duck in meters and x represents the time in seconds. How long was the duck underwater?
Answers
Solving the quadratic equation, it is found that the duck was underwater for two seconds.
The path of the duck after x seconds is modeled by:
[tex]y = 2x^2 - 4x[/tex]
It is a concave up parabola, thus, the negative values of y, when he is underwater, are between the roots.
To find the roots:
[tex]y = 0[/tex]
[tex]2x^2 - 4x = 0[/tex]
[tex]2x(x - 2) = 0[/tex]
[tex]2x = 0 \rightarrow x = 0[/tex]
[tex]x - 2 = 0 \rightarrow x = 2[/tex]
2 - 0 = 2, thus, the duck was underwater for two seconds.

please explain how to use cancellation method with examples. I'm really confused...
Answers
Answer:
Cancellation it enables us to eliminate or get rid of one of the variables, so we can solve a more simplified equation.
Some textbooks refer to the elimination method as the addition method or the method of linear combination.
This is because we are going to combine two equations with addition!
Step 1
First, we align each equation so that like variables are organized into columns.
Step 2
Second, we eliminate a variable.
If the coefficients of one variable are opposites, you add the equations to eliminate a variable, and then solve.
If the coefficients are not opposites, then we multiply one or both equations by a number to create opposite coefficients, and then add the equations to eliminate a variable and solve.
Step 3
Thirdly, we substitute this value back into one of the original equations and solve for the other variable.
Example of how to apply the elimination method for solving systems of equations is attached.

Given the vertex (2, -1 )and the point(0,7), write the vertex form equation of the
quadratic function
Pls help!!!
Answers
Answer:
f(x) = 2(x - 2)² - 1
Step-by-step explanation:
Given the vertex, (2, -1) and the point, (0, 7), we can plug these values into the vertex form of the quadratic function:
f(x) = a(x - h)² + h
where:
vertex = (h, k)
a = determines whether the graph opens up or down, and the wideness or narrowness of the parabola.
h = determines how far left or right the parent function is translated.
k = determines how far up or down the parent function is translated.
We could substitute the given values into the vertex form, and solve for the value of "a":
f(x) = a(x - h)² + h
7 = a(0 - 2)² - 1
7 = a(-2)² - 1
7 = a(4) - 1
Add 1 to both sides:
7 + 1 = a(4) - 1 + 1
8 = 4a
Divide both sides by 4 to solve for a:
8/4 = 4a/4
2 = a
Since a = 2, and the vertex = (2, -1) then we could plug this value into the given function:
f(x) = 2(x - 2)² -1

Use quadratic regression to find
the equation of the parabola
going through these 3 points.
(-1,23), (1,-5), (3,-57)
y = [ ? ]x2 + [ ]x+ [ ]
Enter
Answers
Based on the information given, the required equation of parabola will be y= -3x² - 14x + 12.
SolutionThe parabola passes through the points (-1, 23), (1, -5), (3, -57). Let the equation of the parabola be y = ax² + bx + c.
For point (-1, 23), this will be:
23 = a(-1)² + b(-1) + c
23 = a - b + c ..... equation i
For point (1, -5), this will be:
-5 = a(1)² + b(1) + c
-5 = a + b + c .... equation ii
For point (3, -57), this will be:
-57 = a(3)² + b(3) + c
-57 = 9a + 3b + c .... equation iii
From equation i, 23 = a - b + c
Therefore, c = 23 - a + b .... equation iv
Substitute c into equation ii
-5 = a + b + 23 - a + b
-5 = 2b + 23
2b = -23 - 5.
2b = -28
b = -28/2 = -14
Substitute c into equation iii
-57 = 9a + 3b + 23 - a + b
-80 = 8a + 4b.
-80 = 8a + 4(-14)
-80 = 8a - 56
8a = -80 + 56
8a = -24
a = -24/8 = -3
Therefore, the value of c will be:
c = 23 - a + b
c = 23 -(-3) + (-14)
c = 23 + 3 - 14
c = 12
In conclusion, the required equation of parabola will be y = -3x² - 14x + 12.

Nadia drew a square in her notebook Each side measured 2.5 centimeters
Answers
Answer:
The perimeter of the square is 10 cm.
The area of the square is 6.25 cm.
Step-by-step explanation:
To find perimeter, add all the sides.
2.5 + 2.5 + 2.5 + 2.5 = 10
To find area, multiply the length by the width. Since Nadia drew a square, all the sides will have the same measurement (2.5 cm, in this case). So, simply multiply 2.5 by 2.5, knowing that the length and width of the square are the same size.
2.5 × 2.5 = 6.25
The area of Square is 6.25 cm² and Perimeter of Square is 10 cm.
what is Area and Perimeter of Square?The Area of Square is the product if its side
i.e., Area of square = side x side
and, perimeter of square = 4 x side
Given:
Side of Square= 2.5 cm
then , area of Square= side x side
= 2.5 x 2.5
= 6.25 cm²

Answer:
Y = 58
X = 66
Step-by-step explanation:
So the markers mean that those sides of the triangle are congruent. Because of this, we know that the angles opposite from those sides are equal as well.
In the big triangle, Y will be equal to the empty angle. You can then use:
180 = 64 + 2*Y
Then, solving for Y, you get:
Y = (180-64)/2
Y = 58
You can use the same idea for the smaller triangle. The empty angle will be the same as the angle marked as 57.
180 = 57*2 + X
Then, solving for X, you get:
X = 180 - 57*2
X = 66
