Suppose a is between 4 and 5, and b is between 2 and 4. Find all possible values of the expression a/b

The sequence an = 2(an-1 - 3) is a recursive sequence

The 4th term of the sequence is -42

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

Answer:

  3/8 cubic units

Step-by-step explanation:

The volume of a rectangular prism is given by the formula ...

  V = LWH

Using the given dimensions, we find the volume to be ...

  V = (1/2)(1)(3/4) = 3/8 . . . . cubic units

Answer:

Part (a)

It depends how your calculator calculates quadratic regressions.

For my calculator:

a = 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)

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]

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.

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.

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

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

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
