Find the 4th term in the sequence
with the following definition:
a1 = 0
a2 = -6
an = 2(an-1-3)
The sequence an = 2(an-1 - 3) is a recursive sequence
The 4th term of the sequence is -42
How to determine the 4th term?The given parameters are:
a1 = 0
a2 = -6
an = 2(an-1 - 3)
Start by calculating a3 using:
a3 = 2(a2 - 3)
This gives
a3 = 2 * (-6 - 3)
a3 = -18
Calculate a4 using:
a4 = 2(a3 - 3)
This gives
a4 = 2 * (-18 - 3)
a4 = -42
Hence, the 4th term of the sequence is -42

The product of two consecutive integers is 272. which quadratic equation can be used to find x, the smaller number? x2 1 = 272 x2 − 1 = 272 x2 x − 272 = 0 x2 x 272 = 0
An equation is formed of two equal expressions. The quadratic equation that can be used to find x, the smaller number is x²+x-272.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the first number be x.
Now since the two numbers are consecutive numbers the other number will be (x+1). Also, it is mentioned in the problem that the product of the two numbers is 272. Therefore, the equation that can represent the product will be,
[tex]x \times (x+1) = 272\\\\x^2 + x =272\\\\x^2 + x -272 = 0[/tex]
Thus, the quadratic equation that can be used to find x, the smaller number is x²+x-272.

Answer:
Part (a)
It depends how your calculator calculates quadratic regressions.
For my calculator:
Go to Statistics menuSelect quadratic regression: y=a+bx+cx²Input the x and y values from the given tableGo to options and select regression calca = 1.177142857 = 1.18 (nearest hundredth)
b = 42.22257143 = 42.22 (nearest hundredth)
c = -12.87142857 = -12.87 (nearest hundredth)
⇒ y = 1.18 + 42.22x - 12.87x²
Therefore, the quadratic regression equation in standard form is:
[tex]y = -12.87x^2+ 42.22x + 1.18[/tex]
Part (b)
To estimate the height of the rocket after 5 seconds, input x = 5 into the regression equation:
[tex]\implies -12.87(5)^2+ 42.22(5) + 1.18=-109.47[/tex]
As this gives us a negative value, this means that the rocket would have come back to the ground before 5 s. Therefore, the height of the rocket at 5 s will be 0 ft.
(see attached graph → the rocket will hit the ground at approx 3.3 s)

Find the area.
5cm
3cm
4 cm
Answer:
6 cm²
Step-by-step explanation:
Since 3 side lengths are given, I assume that this figure is a triangle. The area of a triangle can be determined by using hero's formula.
[tex]\text{Area of triangle} = \sqrt{\text{s(s - a)(s - b)(s - c)}[/tex]
⇒ s = Perimeter/2
⇒ a, b, and c = side lenths of triangle
Replacing a, b, and c as the given side lengths:
[tex]\implies \text{Area of triangle} = \sqrt{\text{s(s - 5)(s - 3)(s - 4)}[/tex]
Determining the perimeter of the triangle:
[tex]\text{Perimeter of triangle = Sum of it's side lengths}[/tex]
[tex]\implies \text{Perimeter of triangle =}\ 5 + 4 + 3[/tex]
[tex]\implies \text{Perimeter of triangle =}\ 12 \ \text{cm}[/tex]
Determining the half of perimeter:
[tex]\text{Half of perimeter} = s = \dfrac{\text{Perimeter}}{2}[/tex]
[tex]\implies s = \dfrac{12}{2}[/tex]
[tex]\implies s = 6[/tex]
Replacing the value of "s" in the formula:
[tex]\implies \text{Area of triangle} = \sqrt{\text{6(6 - 5)(6 - 3)(6 - 4)}[/tex]
Evaluating the area:
[tex]\implies \text{Area of triangle} = \sqrt{\text{6(6 - 5)(6 - 3)(6 - 4)}[/tex]
[tex]\implies \text{Area of triangle} = \sqrt{\text{6(1)(3)(2)}[/tex]
[tex]\implies \text{Area of triangle} = \sqrt{\text{6(6)}[/tex]
[tex]\implies \text{Area of triangle} = 6 \ \text{cm}^{2}[/tex]

A group of students formed a circle during a game. The circumference of the circle was about 50.24 feet, and the diameter of the circle was 16 feet. Which expression best represents the value of π?
A group of students formed a circle during a game. The circumference of the circle was about 50.24 feet, and the diameter of the circle was 16 feet. The required expression for value of π is: 3.14
What is diameter of circle?A circle is a form made up of all points on a plane that are at a specific distance from the centre point. In other words, it is the path a moving point in a plane takes to travel around a curve while maintaining a constant distance from another point.
Given that,
The circumference of the circle was about 50.24 feet,
And the diameter of the circle was 16 feet
We have to determine,
Which expression best represents the value of π.
According to the question,
Circumference of the circle = 50.24 feet
Diameter f the circle = 16 feet
Then,
Circumference of the circle = π × d
Circumference of the circle = 50.24 feet
Therefore,
50.24 = π × d
or. π × 16 = 50.24
or, π = 3.14
Hence, The required expression for value of π is: 3.14

A bag Contains five blue marbles two green marbles and three yellow marbles what is the probability of Choosing one Green marble and a yellow marble with replacement what does this mean
Answer:
3/50.
Step-by-step explanation:
There are 10 marbles in the bag.
Probability( a green marble) = 2/10 = 1/5.
Now we replace the green marble in the bag so it contains 10 marbles again.
Probabilty(a yellow marble) = 3/10.
So Probability(Choosing a green then a red with repeacemen)
= 1/5 * 3/10
= 3/50.

Step-by-step explanation:
The number of bacteria on a microscope slide doubles every hour . There are initially 4 bacteria present . Create an explicit function fto model the growth after n hours .
Answer:
I think a possible equation can be; f(n) = 4(2)ⁿ
f(n) = a * bˣ
Where;
f(n) = the function of f for every n value
a = Initial value (in this case it would be 4)
b = Rate of change (in this case it would be 2, since the bacteria doubles)
x = exponent (in this case it would be n)
So our final equation would be:
f(n) = 4(2)ⁿ

Answer :
6.7 mm[tex] \: [/tex]
Explanation :
This is Right Angled Trian1gle.[tex] \: [/tex]
Solution :
We'll solve this using the Pythagorean Theorem.[tex] \: [/tex]
Where,
VW (9 mm) is the Hypotenuse.UV (6 mm) is the Base.UW is the Perpendicular .[tex] \: [/tex]
We know that,
[tex]{\longrightarrow \pmb{\mathbb {\qquad (UV) {}^{2} + (UW) {}^{2} =( VW) {}^{2} }}} \\ \\ [/tex]
Now, we will substitute the given values in the formula :
[tex]{\longrightarrow \pmb{\sf {\qquad (6) {}^{2} + (UW) {}^{2} =( 9) {}^{2} }}} \\ \\ [/tex]
We know that, (6)² = 36 and (9)² = 81. So,
[tex]{\longrightarrow \pmb{\sf {\qquad 36 + (UW) {}^{2} =81}}} \\ \\ [/tex]
Now, transposing 36 to the other side we get :
[tex]{\longrightarrow \pmb{\sf {\qquad (UW) {}^{2} =81 - 36 }}} \\ [/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad (UW) {}^{2} = 45}}} \\ \\ [/tex]
Now, we'll take the square root of both sides to remove the square from UW :
[tex]{\longrightarrow \pmb{\sf {\qquad \sqrt{(UW) {}^{2}} = \sqrt{ 45}}}} \\ \\ [/tex]
When we take the square root of (UW)² , it becomes UW,
[tex]{\longrightarrow \pmb{\sf {\qquad UW = \sqrt{45}}}} \\ \\ [/tex]
We know that, square root of 45 is 6.708.
[tex]{\longrightarrow \pmb{\sf {\qquad UW \approx6.708}}} \\ \\ [/tex]
So,
The measure of the missing side (UW) is 6.7 mm (Rounded to nearest tenth). A bag has 16 marbles in it: 6 red, 4 blue, 3 yellow, and 3 green. A marble is drawn and put back, and

Williana’s mother wants to buy a glass tabletop for their dining room table. The tabletop is shaped like a hexagon with sides measuring 27. 75 inches. If the glass costs $0. 06 per square inch, how much will she spend on the glass table top?
$
The total amount that Williana's mother would spend to buy the glass table top is $120.04.
What is the total cost of the glass table top?The first step is to determine the area of the glass table top.
Area of a hexagon = [(3√3)/2] x a²
a = side length
2.598 x 27.75² = 2000.68 in²
Cost of the table top = 2000.68 in² x 0.06 = $120.04
