A dog won a race at the local fair by running 3 and one fourth miles in exactly 2 hours. At this constant​ rate, how long does i
Novosadov [1.4K]

Answer:

\frac{4}{5} hour

Step-by-step explanation:

Let x represent time taken by dog to run the 1 and three tenths ​-mile state fair​ race.

We have been given that a dog won a race at the local fair by running 3 and one fourth miles in exactly 2 hours.

We will use proportions to solve our given problem as:

\text{Speed}=\frac{\text{Distance}}{\text{Time}}

We will equate both speeds as:

\frac{1\frac{3}{10}}{x}=\frac{3\frac{1}{4}}{2}

\frac{\frac{13}{10}}{x}=\frac{\frac{13}{4}}{2}

\frac{13}{10\cdot x}=\frac{13}{4\cdot 2}

Cross multiply:

13\cdot 10\cdot x=13\cdot 4\cdot 2

10\cdot x=4\cdot 2

\frac{10\cdot x}{10}=\frac{4\cdot 2}{10}

Therefore, it will take \frac{4}{5} hour to complete 1\frac{3}{10} mile state fair​ race.

The graph of the function F(x) = 2x^2-8 is changed. The new graph can be
vova2212 [387]

Answer:

The graph now opens in the opposite direction. The y intercept is shifted up 4.

Step-by-step explanation:

F(x) = 2x^2-8

F(X)= -2x^2-4

We know that the graph is reflected over the y-intercept becuase of the negative sign in the second equation ( F(X)= -2x^2-4)

We know that the intercept is shifted up four, because the number decreased from 8 to 4, and the graph is reflected.

Attacthed is both of the equations graphed to help you visualize this shift!
