Answer: Aₙ = 3*Aₙ₋₁ - 12

Step-by-step explanation:

Here our terms will be denoted as:

Aₙ

Where this is the n-th term of the sequence.

Now we have that the recurrence relation is defined by:

"by multiplying the prior term by 3 and subtracting 12."

Then we will have that:

Aₙ = 3*Aₙ₋₁ - 12

That is the equation to find all the terms in our sequence (remember that we need to know the initial term, A₀ in order to find all the other ones)

Step-by-step explanation:

Answer:

The y-intercept is (0,0)

The x-intercepts are (-3,0), (0,0), and (4,0)

Step-by-step explanation:

So we have the function:

[tex]f(x)=-x^3+x^2+12x[/tex]

And we want to solve for the x- and y-intercepts.

Y)

To solve for the y-intercept, recall that the y-intercept is when the graph touches the y-axis. At that point, the x values is 0. Thus, to find the x-intercept, substitute 0 for x:

[tex]f(x)=-(0)^3+(0)^2+12(0)[/tex]

Simplify:

[tex]f(x)=0[/tex]

So, the y-intercept is (0,0)

X)

To solve for the x-intercept(s), set the function equal to 0 and solve for x:

[tex]0=-x^3+x^2+12x[/tex]

First, factor out a negative x:

[tex]0=-x(x^2-x-12)[/tex]

Factor within the parentheses:

[tex]0=-x(x-4)(x+3)[/tex]

Zero Product Property:

[tex]-x=0\text{ or } x-4=0\text{ or } x+3=0[/tex]

Divide by -1 on the first one. Add 4 on the second one. And subtract 3 on the right:

[tex]x=0\text{ or } x=4\text{ or } x=-3[/tex]

So, our x-intercepts are:

[tex](-3,0), (0,0), (4,0)[/tex]

And we're done :)

Answer:

8 Months

Step-by-step explanation:

The formula in the problem (B = 100 + 75m) can be written as this:

(B-100)/75 = M

The problem gives us the balance (B=700), which we can plug into our new formula to find the number of months (m).

(700-100)/75 = M

M = 8

Answer:

Distance problems are word problems that involve the distance an object will travel at a certain average rate for a given period of time.

The formula for distance problems is: distance = rate × time or d = r × t.

Things to watch out for:

Make sure that you change the units when necessary. For example, if the rate is given in miles per hour and the time is given in minutes then change the units appropriately.

It would be helpful to use a table to organize the information for distance problems. A table helps you to think about one number at a time instead being confused by the question.

Answer:

The finish line

Step-by-step explanation:

This is because, since negative numbers are used to represent points before the finish line, and positive numbers are used to represent points after the finish line, the finish line can only be represented by the number zero. Since on Jonas' map, there is a bridge at -91 3/4 metres, therefore, the bridge is 91 3/4 metres before the finish line. And, since his wife is watching at 14 1/2 metres, since this number is positive, she is 14 1/2 metres after the finish line. So, the finish line itself, will be represented by 0 metres since this is indicated a change from negative to positive.

Answer:

-1/3

Step-by-step explanation:

Since we are given two points, we can find the slope using

m = ( y2-y1)/(x2-x1)

   = ( -1-2)/( 6- -3)

   = ( -1-2) /( 6+3)

   = -3/9

    = -1/3

Answer:

Slope (m) = [tex]\frac{-1}{3}[/tex] = -0.33333333...

Step-by-step explanation:

Slope (m) = ΔY -1

                   ΔX  3

Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

Hey there!

1000 meters are in one kilometer, so 3500 meters are in 3.5 kilometers.

Answer:

3,500 meters

Step-by-step explanation:

So this is conversation rates. So how I like to remember conversion rates in the metric system is King Henry Doesn't Usually Drink Chocolate Milk.

K=Kilo, H=Hecto, D=Deca, U=Unit (meters, liter, grams), D=Deci, C=Centi, M=Milli.

SO between meters (which is the U) and kilometers (which is the K), there's 3 letters so kilometers is 1000 times greater than meters. SO 3.5*1000=3500.

Answer:

(x - 3, y + 3 )

Step-by-step explanation:

Note G(5, - 2 ) → G'(2, 1 )

Requires 3 to be subtracted from 5 to obtain 2 and 3 to be added to - 2 to obtain 1, thus

(x, y ) → (x - 3, y + 3 ) is the translation rule

Answer:

X(s) = 2/[s³(s + 9)]

Step-by-step explanation:

Here is the complete question

Solve for the function X(s) in the Laplace domain by taking the Laplace transform of the following differential equations with given initial conditions.

dx/dt + 9x = 16t²     x(0) = 0 and dx(0)/dt = 5

Solution

dx/dt + 9x = 16t²

Taking the Laplace transform of the differential equation, we have

L{dx/dt + 9x} = L{16t²}

L{dx/dt} + L{9x} = L{16t²}

L{dx/dt} + 9L{x} = 16L{t²}

sL{x} - x(0) + 9L{x}  = 16L{t²}

L{x} = X(s)

L{t²} = 2!/s³

Substituting X(s) and L{t²} into the equation above, we have

sX(s) - x(0) + 9X(s) = 2!/s³

Substituting x(0) = 0 into the equation above, we have

sX(s) - x(0) + 9X(s) = 2!/s³

sX(s) - 0 + 9X(s) = 2!/s³

sX(s) + 9X(s) = 2!/s³

Factorizing X(s), we have

(s + 9)X(s) = 2!/s³

X(s) = 2/[s³(s + 9)]

So X(s) in the Laplace domain is

X(s) = 2/[s³(s + 9)]
