Mathematics
1 answer:
Ira Lisetskai [31]3 years ago
3 0

Answer:

A piece-wise function is given as,

f(x)=\left\{\begin{matrix}-x+1 & x\leq 0\\ x+1 & x>0\end{matrix}\right

So, we see that,

The piece-wise function the function f(x)=|x|+1.

Substituting the values of x in the function, we can find the ordered pairs (x,f(x)) which together gives the graph of the function.

Thus, the graph for the given function can be seen below.

We can see that from this graph that,

f(x)\rightarrow \infty as x\rightarrow \infty and f(x)\rightarrow \infty as x\rightarrow -\infty

Also, the vertex of the graph is (01,), the point at which graph changes its direction.

What is the equation for exponential growth in Biology?
SpyIntel [72]
The exponential growth in biology is A=Pert, where "A" is the ending amount of whatever you're dealing with , "P" is the beginning amount of that same "whatever", "r" is the growth or decay rate, and "t" is time. The formula is related to the compound-interest formula, and represents the case of the interest being "compounded continuously".

Working simultaneously, four fudge machines complete a big order in 32 hours. All the machines at the fudge factory work at the
Alinara [238K]

Answer:

4 Hours

Step-by-step explanation:

Let's say that the rate of the machines 1/x, because every time they complete an order, it takes them x hours. To find x, we have to add the the rates of the individual machines, which would equal the rate of the machines working together. We know that there are four machines working together at the same rate, and it took them 32 hours.

So:

1/x + 1/x + 1/x + 1/x = 1/32

1/4x = 1/32

4x = 32

x = 8

Thus, the rate of the machines is 1/8.

Now we have to find the time of the order with only half of the machines working together. This time, we don't know the combined rate, so I'll substitute it for y.

1/8 + 1/8 = 1/y

1/4 = 1/y

y = 4

The time taken to complete it is 4 hours.

Can somebody help me
saveliy_v [14]

Answer:

Y=5

You must first divide b (-10) by two and square it to know what you need to make a perfect square (25). You must then add or subtract the amount to make C (-13) into that number (add 38). Don't forget to do it on the other side too! (3 becomes 41) You then factor the left side. ((Y-5)^2=41) The result is your answer. (Y=5)
