[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

a is a leg
b is another leg
c is the hypotenuse

Step-by-step explanation:

Step 1: Define

Identify variables

a = 12 cm

c = 17 cm

Step 2: Solve for b

Substitute in variables [Pythagorean Theorem]: 12² + b² = 17²
Evaluate exponents: 144 + b² = 289
[Subtraction Property of Equality] Subtract 144 on both sides: b² = 145
[Equality Property] Square root both sides: b = √145
[√Radical] Evaluate: b = 12.0416
Round: b ≈ 12.0

Which of the following choices is the simple formula for the nth term of the following arithmetic sequence?

VladimirAG [237]

First, we start off with the nth term formula for an arithmetic sequence, which is
$a_{n} =a_{1}+(n-1)d$

plug in the sequence numbers where they belong

$a_{n}=5+(n-1)*(-4)
$
$a_{n}=5+(-4n+4)$
$a_{n}=5-4n+4$
$a_{n}=-4n+9$

And this is the final answer
$-4n+9$

a card is drawn at random from a standard 52 card deck has a 1/13 chance of being at 8. What is the probability of the car not b

Free_Kalibri [48]

Answer:

12/13

Step-by-step explanation:

There are 52 cards in the deck

4 are aces

That leaves 52-4 or 48 that are not aces

P(not an aces) = cards that are not aces / total

= 48/52
