Answer: $z \ge -10$

Reason: The graph shows all values that are z = -10 or larger.

The closed endpoint at -10 indicates we include it with an "or equal to".

If it was an open hole endpoint, then we'd say z > -10 instead.

Answer:

h(0) = 6

Step-by-step explanation:

Plug x = 0 to find h(0)

h(0) = -10.0 + 6 = 6

Answer:

9. $a_n=7+6n$

10. $a_n=a_{n-1}+7$

Step-by-step explanation:

9. Given the sequence

$13, 19, 25, ...$

In this sequence,

$a_1=13\\ \\a_2=19\\ \\a_3=25\\ \\...$

Note that

$a_2-a_1=19-13=6\\ \\a_3-a_2=25-19=6,$

then the common difference in this sequence is $d=6$

You have

$a_1=13\\ \\d=6,$

then the explicit formula is

$a_n=a_1+(n-1)d\\ \\a_n=13+(n-1)\cdot 6\\ \\a_n=13+6n-6\\ \\a_n=7+6n$

10. Given the sequence

$-10,-3, 4, 11, ...$

In this sequence,

$a_1=-10\\ \\a_2=-3\\ \\a_3=4\\ \\a_4=11\\ \\...$

Note that

$a_2-a_1=-10-(-3)=-10+3=-7\\ \\a_3-a_2=-3-4=-7\\ \\a_4-a_3=11-4=7,$

then the common difference in this sequence is $d=7$

You have

$a_1=-10\\ \\d=7,$

then the recursive formula is

$a_n=a_{n-1}+d\\ \\a_n=a_{n-1}+7$

A histogram is used to show the frequency of data, where the length of the bar represents the frequency.

50 students drank the recommended amount of water.

The recommended amount is given as:

$Amount \ge 48$

See attachment for histogram.

From the histogram, we have the following observations

The lengths of all bars of the histogram are less than 48, except one.

The length of the bar above 48 is 50.

This means that: 50 students drank the recommended amount of water.

Hence, the number of students is 50
