Answer:
Her second lap was <u>8%</u> better when compared to her first lap.
Step-by-step explanation:
Given:
Emily ran her first lap in 75 seconds she ran her second lap in 69 seconds.
Now, to find how much better was her second lap when compared to her first lap.
Emily ran her first lap in 75 seconds.
Emily ran her second lap in 69 seconds.
So, we get the difference in seconds:
<u><em>Thus, in her second lap she was 6 seconds better than first.</em></u>
Now, to get the percentage of her first lap better than second:
Therefore, her second lap was 8% better when compared to her first lap.
Answer:
Therefore, the solutions of the quadratic equations are:
The graph is also attached.
Step-by-step explanation:
The solution of the graph could be obtained by finding the x-intercept.
Finding the x-intercept by substituting the value y = 0
so
∵ y = 0
So, when y = 0, then x values are 3, and 5.
Therefore, the solutions of the quadratic equations are:
The graph is also attached. As the graph is a Parabola. It is visible from the graph that the values of y = 0 at x = 5 and x = 3. As the graph is a Parabola.
