What’s the vertex of f(x)=(x+5)^2

1 answer:

6 0

Answer: (-5, 0)

Step-by-step explanation: The equation is already in completing the square form, a(x-h)^2 + k so you have both the x and y values for the vertex. Since there is no k here, the y value is 0.

With a short time remaining in the day, a delivery driver has time to make deliveries at 7 locations among the 9 locations rema

kotegsom [21]

<h2>Answer:</h2>

The different possible routes are :

181440

<h2>Step-by-step explanation:</h2>

We are asked to find the number of different routes that are possible to choose 7 locations among the 9 locations remaining.

This means that we have to chose the locations and also we have to arrange them in different orders according to the different order of locations.

The method we have to use is a method of permutation.

When we have to chose and arrange r items out of a total of n items then the formula is given by:

$n_P_r=\dfrac{n!}{(n-r)!}$

Here we have: n=9

and r=7

Hence, the different possible routes are:

$9_P_7=\dfrac{9!}{(9-7)!}\\\\\\9_P_7=\dfrac{9!}{2!}\\\\\\9_P_7=181440$

Hence, the answer is:

181440

Consider these four functions. Choose the one which will be the greatest as x → ∞. A) h(x) = 3x B) f(x) = x25 C) g(x) = 5x500 D)

Nikolay [14]

For this case what you should know is that all functions tend to infinity when x tends to infinity.
However, there are functions that grow faster than others.
In this case, the function that grows fastest is the one with the highest exponent.
We have then:
g (x) = 5x ^ 500
The exponent of 500 makes the function grow to infinity faster than the other functions.
Answer:
C) g (x) = 5x500
