Using the function concept, it is found that f is a function, as each student is related to only one GPA and only one number of credits.

In a function, <u>one value of the input can be related to only one value of the output</u>.

In this problem:

The input is the student.

The output is the student GPA, and the number of credits earned.

Each student is related to only one GPA and only one number of credits, hence <u>one value of the input is related to only one value of the output</u>, and f is a function.

Solve for angle C please

zubka84 [21]

Answer:

13.3 cm

Step-by-step explanation:

We can use the Pythagoream Theorem to identify any missing angles!

$a^{2} +b^2=c^2$

In this case, will leave c for a^2!

$a^2+20^2=24^2$

$a^2+400=576$

$576-400=a^2$

$a^2=176$

$\sqrt{176} = 13.3$
