Hi! We’re going to use the pythagorean theorem to answer this.
3 + x^2 = 8
subtract 3 from 8
x^2=5
take the square root of both sides
x=sqrt5
"A student" doesn't register for 46,140 credits, unless he wants to be very very busy.
If ALL of the students on campus register for 46,140 credits, then many colleges
would estimate the number of full-time students by using the formula
f = n / 15 = 46,140 / 15 = <u>3,076</u> students.
That's not the formula for 'n'. 'n' is the total number of credits for the semester,
and the question tells you what 'n' is. Knowing 'n', the formula helps you find 'f'.
Answer:
x = 9
Step-by-step explanation:
Create an equation:
x = some number
and = add
other number = -15
x + (-15) = -6
remove () using rule
x - 15 = -6
add +15 to both sides
x = 9
Answer:
Step-by-step explanation:
<u>Given</u>
<u>Conjugate of z is:</u>
<u>Product zz' is:</u>
- zz' = (-3 + 5i)(-3 - 5i) = (-3)² - (5i)² = 9 - 25(-1) = 9 + 25 = 34
