Arocket ship is travelling at an average speed of 1.75 × 104 miles per hour. how many miles will the rocket ship travel in 1.2 × 102 hours? 1. write the expression:       (1.75 × 104)(1.2 × 102) 2. rearrange the expression:     (1.75 × 1.2)(104 × 102) 3. multiply the coefficients:      (2.1)(104 × 102) 4. apply the product of powers:    2.1 × 10y the rocket ship will travel 2.1 × 10y miles. what is the value of y in the solution?

y = 4 + 2 = 6 ( the sum of the exponents)

The distance covered is  

The value of y is 6.          

Step-by-step explanation:

Given : A rocket ship is travelling at an average speed of miles per hour.

To find : How many miles will the rocket ship travel in  hours and find the value of y in the solution expression?

Solution :

The speed is   miles per hour.

The time taken is    hours

The distance covered is

Step 1 -  Write the expression:

Step 2 - Rearrange the expression :

Step 3 - Multiply the coefficients :

Step 4 - Apply the product of powers :

The distance covered is  

On comparing with  

The value of y is 6 in the solution.

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
