Answer:

The set of all real values except 7

Step-by-step explanation:

We are given that,

Domain of the function f(x) is 'the set of all real values except 7'.

Domain of the function g(x) is 'the set of all real values except -3'.

It is required to find the domain of (g\circ f)(x).

Now, we know that,

<em>The composition  (g\circ f)(x) of functions f(x) and g(x) will be defined where the function f(x) is defined.</em>

Since, the domain of f(x) is 'the set of all real values except 7'.

Thus, the domain of (g\circ f)(x) is also 'the set of all real values except 7'.

A cyclist travels at an average speed of 13 mph for 3 hours.<br> How far did she travel in miles?
alexgriva [62]

Answer:

39 miles

Step-by-step explanation:

We know that a cyclist travelled at an average rate of 13 miles per hour for 3 hours and are asked to how far she travelled in miles.

To solve, we need to take into mind that for three hours, the cyclist drove 13 miles per hour.

Meaning that for every hour, 13 miles were driven.

Therefore we need to multiply 13 by 3 to get our answer :

13 miles * 3hrs

39 miles

if the point (-4,5) and (0,2) are used to find the slope of the line the slope is -3/4 what is the slope if the points (0,2) and
wariber [46]
The slope will be -3/4
To find slope you just place the change in y over the change in x.
2- -1=3
0-4= -4
The slope is -3/4 which is the same as before

The number of permutations of the 25 letters taken 2 at a time (with repetitions) is:25^{2}
The number of permutations of the 9 digits taken 4 at a time (with repetitions) is:
9^{4}
Each permutation of letters can be taken with each permutation of digits, therefore the total number of possible passwords is:
25^{2}\times 9^{4}=4,100,625
