Round 62,686 to nearest hundredth
Semenov [28]

Answer: 62.7 is rounded to the nearest hundredth.

Step-by-step explanation:

if you look at the 6 at the hundredth place then you have to look at the number next to it, which is 8 and since it's 5 and greater it the 6 becomes a 7 and therefor, the answer is 62.7.

Can someone pls explain this?
ryzh [129]

Answer:

A piecewise function.

Step-by-step explanation:

The problem you showed is a <em>piecewise function.</em>

In this problem, you have to plug in 3 for the value x.

However, if you take a look at the conditions that value x has, it never says that x can equal 3. <em>Thus, this function cannot be true.</em>

<em>Way to check this input is undefined: </em>

Plug in 3 for the variable x. On the first function, your output will be 4. On the second function, your output will be 8.

According to the definition of a function, a function can have many inputs but only one output. In this case, this function has one input, that is 3, but produces two outputs.

Could you help with maths please? All shown on the picture :)
uysha [10]

Answer:

4 is tenths (a) and 5 is hundredths (b)

Step-by-step explanation:

Now, 0.45

0 indicates the ones place (it comes before the decimal)

0.45 can also be written as:

0.4+0.05

= 4/10+5/100

what can we conclude from this?

we can say that 4 is in the tenths whilst 5 is in the hundredths.

therefore, a is 4 and b is 5.

Hope this helps you! :)
