Plzzz help me

Suppose your business has a special checking account used just for paying the phone bill. The balance is $1530.00 this month. Next month the balance will be $1496.30, after that it will be $1432.60, and on the third month the balance will be $1428.90. Write an explicit formula to represent the balance in the account as an arithmetic sequence. How many months can you pay your phone bill without depositing any more money in the account?

A) An= 1530 + (n-1) ( -33.70); 46 months

B) An = 1530 + (n-1) (-33.70); 45 months

Please explain for me how you got the answer. Thank you so much

Answer:

  x^2 -5x +6 = 0

Step-by-step explanation:

Perhaps the easiest way to do this is to find the roots of the given equation, then write the equation that has reciprocal roots. The given equation can be factored as ...

  (2x -1)(3x -1) = 0   ⇒   roots 1/2, 1/3

Then the factoring of the equation with reciprocal roots is ...

  (x -2)(x -3) = 0

  x^2 -5x +6 = 0

_____

If p is a root, then (x -p) is a factor. If (ax -b) is a factor, then b/a is a root, the value of x that makes that factor zero.

The average rate of the function is 4.

The average rate of change of a function f(x) over an interval [a, b] is defined as the ratio of "change in the function values" to the "change in the endpoints of the interval". i.e., the average rate of change can be calculated using [f(b) - f(a)] / (b - a). In other words, the average rate of change (which is denoted by A(x)) is the "ratio of change in outputs to change in inputs". i.e.,

A(x) = (change in outputs) / (change in inputs)

= Δy / Δx

= [f(b) - f(a)] / (b - a)

given function:

f(x) = -x² + 6x + 12

Now,

let a= -3, b = 5

and, f(b)= -(5*5) + 6*5 + 12

 =-25+ 30 +12

 = 17

f(a) = -(- 3 * (-3))+6(-3) +12

  = -9-18+12

  = -15

Now,

f(b)- f(a) / (b-a)

=17 -(-15))/5-(-3)

=32/ 8

=4

Answer:

24º

Step-by-step explanation:

90-66 = 24º. So since complementary angles are 2 angles that add up to 90 degrees. That means that 66 + x = 90 using the information given. Then we use algebra and get that x =24. Therefore the answer is 24º.

Answer:

The supplement of 66° is the angle that when added to 66° forms a straight angle (180° ).

Step-by-step explanation:

A supplementary angle is an angle that equals 180°. So now we know that the two angles added together will give us 180°, we can use this to check at the end.

Let's call the smaller angle x

We also know that the larger number is 66° more than the smaller. This gives us:

x+x+66°=180°.

x is equal to the smaller angle, and the second angle is (x) - the smaller number with an extra 66°, giving us the difference.

Now we can simplify this by subtracting 66° from both sides.

The difference quotient for f(x) = 3x2 – 12 is 6x + 3h

The function is given as:

f(x) = 3x^2 – 12.

Calculate f(x + h)

f(x + h) = 3(x + h)^2 – 12

The difference quotient is then calculated using:

[tex]f'(x) = \frac{f(x + h) - f(x)}{h}[/tex]

This gives

[tex]f'(x) = \frac{3(x + h)^2 - 12 - 3x^2 + 12}{h}[/tex]

Evaluate the difference

[tex]f'(x) = \frac{3(x + h)^2- 3x^2}{h}[/tex]

Expand

[tex]f'(x) = \frac{3x^2 + 6xh + 3h^2- 3x^2}{h}[/tex]

Evaluate the difference

[tex]f'(x) = \frac{6xh + 3h^2}{h}[/tex]

Evaluate the quotient

f'(x) = 6x + 3h

Hence, the difference quotient for f(x) = 3x2 – 12 is 6x + 3h

Answer:

hotdogs 3.45

rolls 2.60

Step-by-step explanation:

6h + 8r = 41.5

r=h-.85

6h + 8(h-.85)=41.5

6h + 8h - 6.8 = 41.5

14h = 41.5 + 6.8

14h = 48.3

h=48.3/14

h=3.45

Answer:

(x + 1 ) is a factor

Step-by-step explanation:

Given a polynomial with roots x = a, x = b , then the corresponding factors are

(x - a) and (x - b)

From the graph

The roots are x = - 1 and x = 4 , thus factors are

(x - (- 1)) and (x - 4) , that is

(x + 1) and (x - 4)

(x + 1) is the required factor
