Is this a function?

vredina [299]

Answer:

Yes

Step-by-step explanation:

To be a function, the graph must pass the vertical line test.

The vertical line test is simple. Imagine you draw an infinite number of vertical lines. In all of these lines, it should never hit the function twice in the same x value.

For example, if it hits (4, 2) and (4, 7), the graph is not a function because there are two points with the same x value.

The difference between both unit rates rounded off to the nearest tenth is: 0.4 meters per second

Step-by-step explanation:

We have to calculate his unit rate for both type of races

So,

Distance = 400m

Time = 43 sec

$Unit\ rate = U_1= \frac{Distance}{Time}\\=\frac{400}{43}\\=9.30\ meters\ per\ second$

Distance = 300m

Time = 31 sec

$Unit\ Rate= U_2=\frac{300}{31}\\=9.68\ meters\ per\ second$

The difference between both unit rates is:

$U_2-U_1 = 9.68-9.30\\=0.38 => 0.4\ meters\ per\ sec$

Hence,

The difference between both unit rates rounded off to the nearest tenth is: 0.4 meters per second

The logarithm of a quotient can be written as a difference of logarithms:

$\log_3\left(\dfrac uv\right) = \log_3(u) - \log_3(v)$

You can also think of this as a combination of the product-to-sum and reciprocal/power properties of logarithms:

$\log_3\left(\dfrac uv\right) = \log_3\left(u \times \dfrac1v\right) = \log_3(u) + \log_3\left(\dfrac1v\right) = \log_3(u) - \log_3(v)$

To summarize,

$\log_b(mn) = \log_b(m)+\log_b(n)$

$\log_b\left(\dfrac mn\right) = \log_b(m) - \log_b(n)$

$\log_b\left(m^n\right) = n \log_b(m)$
