The complete question is:

Oscar and Maria each wrote an equation that they felt represented the proportional relationship between distance in kilometers and distance in miles. One entry in the table paired 152 km with 95 miles. If represents the number of kilometers and represents the number of miles, who wrote the correct equation that would relate kilometers to miles? Explain why.

  • Oscar wrote the equation = 1.6, and he said that the unit rate 1.6 / 1

represents kilometers per mile.

  • Maria wrote the equation = 0.625 as her equation, and she said that 0.625 represents kilometers per mile.

Answer:

  • <em><u>Oscar wrote the correct equation that would relate kilometers to miles.</u></em>

Explanation:

<u>1. Table</u>

km         miles

152          95

             

<u />

<u>2.  Set the proportion with / and solve for k</u>

  • / = 152 km / 95 miles
  • / = 1.6 km / 1 miles
  • = 1.6 , where  1.6 / 1 represents kilometers per mile.

So, Oscar is right.

<u>3. Solve the proportion for </u>

  • / = 152 km / 95 miles
  • / = 95 miles / 152 km
  • = 0.625 , where 0.625 represents miles per kilometer

So, Maria is wrong.

Consider function f and function g.
ivolga24 [154]

The statement the graphs of both functions have a vertical asymptote of x=0 and statement unlike the graph of function f, the graph of function g decreases as x increases are true.

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

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have two functions:

f(x) = lnx

g(x) = -5 lnx

The domain of the both functions x > 0

The function will be touch the y-axis when x reaches to the infinite.

The graphs of both functions have a vertical asymptote of x=0.

Unlike the graph of function f, the graph of function g decreases as x increases.

The graph of function g is the graph of function f vertically stretched by a factor of 5 and reflected over the x-axis.

Thus, the statement the graphs of both functions have a vertical asymptote of x=0 and statement unlike the graph of function f, the graph of function g decreases as x increases are true.

Will u help me?

Answer:

Charles practiced for the relay race for D. 9 hours last week.

Step-by-step explanation:

First, I would find the ratios the ratios for converting hurdle to javelin and javelin to relay.

Hurdle : Javelin ; 5 : 1.5

Javelin : Relay ; 2.5 : 5 or  1 : 2

Next, find the factors compared to the original numbers for hurdle to javelin.

15 / 5 = 3

To find the amount of javelin time they did, multiply 1.5 by the factor we got, 3.

1.5 * 3 = 4.5

Finally, double 4.5, since Charles does twice as much relay than he does javelin.

4.5 * 2 = 9 hours
