Answer:

First problem:  max when x = 4

Second problem:  min when x = 1

Step-by-step explanation:

The graph of f(x) = –|x – 4| – 5 is a translation of that of g(x) = -|x|.  The vertex of the latter is (0, 0).  First this must be translated 4 units to the right and then the resulting graph 5 units downward.  The vertex of this translation is (4, -5).  Since this graph opens downward, this (4, -5) is the maximum function value, that is, when x = 4.

The graph of f(x) = x2 – 2x +­ 1, or (better yet) f(x) = x^2 – 2x +­ 1, or

f(x) = (x - 1)^2 + 0, is that of a parabola that opens upward and has its minimum at x = 1, or (1, 0).

What is the probability that two people selected at random have the same birthday
arlik [135]
Hello, there!

There are 365 days in a year.

We already know that one person has a birthday on blank day. We will call this person a. That means that there is a 100% chance that they have that birthday.

Because there are 365 days in a year, the odds of person b having a birthday on a certain day is 1/365

Odds of person A having that birthday: 365/365

Odds of person B having that birthday: 1/365

To find the odds of them having the same birthday, we must multiply these odds.

365/365 * 1/365 = 1/365

1/365 = 0.27%

This means that there is a 0.27% chance that both people share the same birthday.


I hope I helped!

What is the value of z?
crimeas [40]

Answer:

23°

Step-by-step explanation:

The total of the angles in a triangle add up to 180°.

Our equation here is 62 + 95 + z = 180

Lets find what 62 + 95 is: 62 + 95 = 157

Then we can find the remainder (157 + x = 180). 180 - 157 = 23°

Therefore the missing angle (z) is 23°

In a class of 23 student the girls were 7 more than the boys how many boys were in the class​
Softa [21]

Answer:

x=# of boys

x+7=# of girls

x+x+7=25

2x+7=25

2x=25-7

2x=18

x=18/2

x=9 boys

x+7=16 girls

 

If you don't understand variables use trial and error.

 

Boys     Girls

1           8

2           9

3           10

4           11

5           12

6           13

7           14

8           15

9           16   9+16=25 students

 

You could start this way...

 

Boys     Girls

12        13

11        14

10        15

9          16     16 is 7 more than 9
