Find the length of the missing side

inn [45]

<h3>Answer: 9</h3>

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

Work Shown:

a = unknown = leg #1

b = 12 = leg #2

c = 15 = hypotenuse

Plug those values into the pythagorean theorem and solve for 'a'

a^2 + b^2 = c^2

a^2 + (12)^2 = (15)^2 .... substitution

a^2 + 144 = 225

a^2 = 225 - 144 ... subtracting 144 from both sides

a^2 = 81

a = sqrt(81) .... applying square root to both sides

a = 9

According to the scatterplot below, which statement is correct? A graph titled Courses Completed versus Remaining Credits Needed

kondaur [170]

Answer:

Option B.

Step-by-step explanation:

It is given that a graph titled Courses Completed versus Remaining Credits Needed to Graduate has courses completed on the x-axis and Credits need to graduate on the y-axis.

Points plotted are (4, 110), (8, 76), (16, 63), (20, 53), (24, 33).

Since, x-axis represents the courses completed, therefore the input, or independent variable is courses completed.

Since, y-axis represents the Credits need to graduate, therefore the output, or dependent variable is Credits need to graduate.

Therefore, the correct option is B.

LekaFEV [45]

Answer:

$\mathrm{12\sqrt{5} \: \: inches}$

Step-by-step explanation:

Use Pythagorean theorem, where:

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

Substitute in the values.

$24^2+12^2=c^2$

$c^2=576+144$

$c^2=720$

$c=\sqrt{720}$

$c=12\sqrt{5}$

$c=26.83281$
