I need help im doing IXL right now (BB.3 Complete a function table: quadratic functions)
i just need help with this final question (posted with a picture)
Answers
Answer:
0, 2, 4
Step-by-step explanation:-2 + 2 = 0 + 2= 2 + 2 = 4
The function table is solved and the quadratic equation is f ( x ) = -3x²
What is Quadratic Equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as A
Now , the value of A is
f ( x ) = -3x²
when x = -2
f ( -2 ) = -3 ( -2 )²
f ( -2 ) = -12
And , when x = 0
f ( 0 ) = 0
when x = 2
f ( 2 ) = -12
when x = 4
f ( 4 ) = -48
Hence , the function table is f ( x ) = { -12 , 0 , -12 , -48 }

A cylinder has a height of 5 cm. What is the lateral and surface area of cylinder, if the circumference of one circle is 18.84 cm?
Answers
Answer:
Lateral Surface Area = 94.25 cm²
Surface area = 150.8 cm²
Step-by-step explanation:
A cylinder has a height of 5 cm. What is the lateral and surface area of cylinder, if the circumference of one circle is 18.84 cm?
Step 1
We have to find the radius of the cylinder
We are told in the question that:
The circumference of one circle is 18.84 cm
Circumference of a circle = 2πr
18.84cm = 2πr
r = 18.84/2π
r = 2.9984791279cm
Approximately the radius = 3cm
Step 2
We find the Lateral Surface Area of the Cylinder
The formula =2πrh
r = 3cm
h = 5cm
=2×π × 3 × 5
= 94.24778 cm²
Approximately = 94.25 cm²
Step 3
We find the Surface Area of the Cylinder
The formula =2πr(r + h)
r = 3cm
h = 5cm
=2×π × 3 × 5(3 + 5)
= 150.79645 cm²
Approximately = 150.80 cm²
Johanna used tiles to build a rectangular array with an area of 54 W. All the possible dimensions of the array

Factors of 54 : 1, 2, 3, 6, 9, 18, 27, 54
Muliplication pairs :
(6 * 9) = 54
(18 * 3) = 54
(27 * 2) = 54
(54 * 1) = 54
Hence, there are 4 possible dimensions of the array

Use the rule "divide by 3" to continue the pattern. Then write the four terms of a different pattern that follows the same rule
Answers
Answer:
[tex](a)[/tex]
[tex]Pattern: 2187, 729, 243, 81, 27, 9,3, 1[/tex]
[tex](b)[/tex]
[tex]Pattern = 972,324,108,36[/tex]
Step-by-step explanation:
Given [Missing from the question]
[tex]Pattern: 2187, 729, 243, 81[/tex]
Solving (a): Continue the pattern using the divide by 3 rule
To do this, we simply divide the last term by 3, to get the next term.
So, we have:
[tex]81/3 = 27[/tex]
[tex]27/3 = 9[/tex]
[tex]9/3 = 3[/tex]
[tex]3/3 = 1[/tex]
So, the pattern is:
[tex]Pattern: 2187, 729, 243, 81, 27, 9,3, 1[/tex]
Solving (b): 4 terms of a different pattern using the same rule.
Let the first term be: 972
So, the next three terms is:
[tex]972/3 =324[/tex]
[tex]324/3 = 108[/tex]
[tex]108/3 =36[/tex]
So, the pattern is:
[tex]Pattern = 972,324,108,36[/tex]

Choose one of the theorems about chords of a circle and state it using your own words.
Create a problem about chords that uses the theorem that you explained. Solve the problem.
examples below:
Answers
1.The Chord Intersection Theorem:
If 2 chords of a circle are AB and CD and they intersect at E, then
AE * EB = CE * ED.
Problem.
Two Chords AB and CD intersect at E. If AE = 2cm , EB = 4 and CE = 2.5 cm, find the length of ED.
By the above theorem : 2 * 4 = 2.5 * ED
ED = (2 * 4) / 2.5
= 3.2 cm.
2.1. A given chord on a circle is perpendicular to a radius through its center, and it is at a distance less that the radius of the circle.
2. A circle of center O has a radius of 13 units. If a chord AB of 10 units is drawn at a distance, d, to the center of the circle, determine the value of d.
3. From question 2, the radius = 13 units, length of chord = 10 units and distance of chord to center of the circle is d.
A radius that meet the chord at center C, and divides it into two equal parts.
So that;
AC = CB = 5 units
Applying Pythagoras theorem to ΔOCB,
OC = d, CB = 5 units and OB = 13 units
= +
169 = 25 +
169 - 25 =
144 =
⇒ d =
= 12 units
Therefore, the chord is at a distance of 12 units to the center of the circle
