Sum to infinity  =  a1 / ( 1 - r)   (This is a geometric series  a1 = first term, r = common ratio)

Here r = 3/9  = 1/3 and a1 = 9 

So the answer is 9 / (1 - 1/3)  = 9 / 2/3 = 9 * 3/2 = 13.5 Answer

3) Scenario 1 Scenario 2 y = 50x x is time in hours y is distance in miles Compare the scenarios and determine which shows the g
Olegator [25]

Answer:

Option A.

Step-by-step explanation:

Consider the below figure attached with this question.

Scenario 1 represented by the graph.

From the graph it is clear that the line passes through the points (1,60) and (2,120).

Slope of the line is

y=\dfrac{y_2-y_1}{x_2-x_1}

y=\dfrac{120-60}{2-1}=60

The slope of line is 60. It means the speed is 60 miles per hour.

Scenario 2 defined by the equation,

y=50x

If an equation defined as y=mx+b, then m is slope and b is y-intercept.

m=50

The slope of line is 50. It means the speed is 50 miles per hour.  

The slope of Scenario 1 is greater than slope of Scenario 2. So, the Scenario 1 shows the greater speed.

Hence, the correct option is A.

I am Lyosha [343]

Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients. The polynomial whose factors are (a²-6) and (a²+4) is a⁴ - 2a² - 24.

<h3>What is a polynomial?</h3>

Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables involved.

Example: x²+3x+5 is a polynomial.

The polynomial whose factors are (a²-6) and (a²+4) is,

P(x) =  (a²-6)(a²+4)

      = a⁴ + 4a² - 6a² - 24

      = a⁴ - 2a² - 24

Hence, The polynomial whose factors are (a²-6) and (a²+4) is a⁴ - 2a² - 24.
