Answer:

The total cost is: $13.50              

Step-by-step explanation:

Given

Item cost = $12.50

Sales tax = 8% = 0.08

To determine

Total cost = ?

Sales amount can be calculated by multiplying item cost 12.50 by sales tax 8% or 0.08.

Sales amount = Item cost × 0.08

                       = 12.50 × 0.08

                       = $1

The total cost can be calculated by adding the item cost plus the Sales amount.

Total cost = Item cost + Sales amount

                 = 12.50 + 1

                 = $13.50

Therefore,

The total cost is: $13.50

Answer:

13.50$

Step-by-step explanation:

\frac{x}{12.50}  =  \frac{8}{100}

(x)100 = (8)12.50

(x)100 = 100

\frac{(x)100}{100}  =  \frac{100}{100}

x =  \frac{100}{100}

x = 1

12.50 + 1 = 13.50

13.50$

What is an equation of the line that is perpendicular to y-4=2(x-6) and passes through (-3,-5)
Nat2105 [25]

Answer:

y = -1/2 x - 13/2

Step-by-step explanation:

what is an equation of the line that is perpendicular to y-4=2(x-6) and passes through (-3,-5)

First, we need the slope of the given line.

y - 4 = 2(x - 6)

y - 4 = 2x - 12

y = 2x - 8

The slope of the given line is 2.

The slopes of perpendicular lines are negative reciprocals, so the slope of the perpendicular is -1/2.

y = -1/2 x + b

We use the given point as x and y and solve for b.

-5 = -1/2(-3) + b

-10 = 3 + 2b

2b = -13

b = -13/2

The equation of the perpendicular line is:

y = -1/2 x - 13/2

Find the generating function for the sequence 1,-2,4,-8, 16, ...
kirill [66]

Answer:

  a(x)=\dfrac{1}{1+2x}

Step-by-step explanation:

The generating function a(x) produces a power series ...

  a(x)=a_0+a_1x+a_2x^2+a_3x^3+\dots

where the coefficients are the elements of the given sequence.

We observe that the given sequence has the recurrence relation ...

  a_0=1;a_n=-2a_{n-1} \quad\text{for n $>$ 0}

This can be rearranged to ...

  a_n+2a_{n-1}=0

We can formulate this in terms of a(x) as follows, then solve for a(x).

\sum\limits^{\infty}_{n=1} {a_{n}x^n} =a(x)-a_0 \quad\text{and}\\\\\sum\limits^{\infty}_{n=1} {2a_{n-1}x^n} =(2x)a(x) \quad\text{so}\\\\\sum\limits^{\infty}_{n=1} {(a_n+2a_{n-1})x^n}=0=a(x)-a_0+2xa(x)\\\\a(x)=\dfrac{a_0}{1+2x}=\dfrac{1}{1+2x}

The generating function is ...

  a(x) = 1/(1+2x)

Nine less than three times a number is greater than forty
pentagon [3]
Start with an equation.
Nine less... so -9
3 times a number = 3x
Greater than 40 is >40

So put together is 3x-9>40
When solving I imaging the greater than sign as an equal sign. Less confusing.
3x-9=40
3x=49
x>49/3
