Which of the following situations would best be modeled by a discrete relationship? a. A teacher counts the number of students i
Nata [24]

Answer:

Option d is correct.

Step-by-step explanation:

Discrete values are those which take an integer value not in fraction.

Option A is discrete because there will be certain number of students in class say 20 or 30

We can not have 20.5 students

Therefore, option a is correct.

Option B is not discrete because many people can have age say 65 and a half years and weight can be in decimals say 50.5 kgs.

Option C is correct because he is saving a proper integer number of money.

Therefore, option d is correct that is both A and C are correct.

F(x)=x^2-7 and h(x)=7x-5, then f(h(2))= ?
ziro4ka [17]
<h3>Answer:    74</h3>

==================================================

Work Shown:

h(x) = 7x-5

h(2) = 7(2)-5

h(2) = 14-5

h(2) = 9

f(h(2)) = f(9)

f(x) = x^2-7

f(9) = 9^2-7

f(9) = 81-7

f(9) = 74

f(h(2)) = 74

-----------

Here's a slightly alternative approach:

f(x) = x^2 - 7

f(h(x)) = ( h(x) )^2 - 7

f(h(x)) = ( 7x-5 )^2 - 7

f(h(2)) = ( 7*2-5 )^2 - 7

f(h(2)) = ( 14-5 )^2 - 7

f(h(2)) = ( 9 )^2 - 7

f(h(2)) = 81 - 7

f(h(2)) = 74
