Identify tan P as a fraction and as a decimal rounded to the nearest hundredth. HELP PLEASE!!
KonstantinChe [14]
<h3>Answer: Choice C</h3>

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

Work Shown:

Reference angle = P

Opposite side = QR = 8.5

Adjacent side = QP = 16

tan(angle) = opposite/adjacent

tan(P) = QR/QP

tan(P) = 8.5/16

tan(P) = 0.53125

tan(P) = 0.53

Elinor determined that a triangle with side lengths 6, 10, and 8 does not form a right triangle. 62 + 102 = 82 36 + 100 = 64 136
bazaltina [42]

Answer:

incorrect

Step-by-step explanation:

To determine if the triangle is right

If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right, that is

longest side = 10 and 10² = 100

6² + 8² = 36 + 64 = 100

Thus the triangle is right.

She should have added 6² and 8² and compared that to 10²

A quadratic equation is shown below:
lys-0071 [83]
16x^2 − 8x + 1 = 0

<span>Part A: 
</span>b^2 - 4ac for ax^2 + bx + c

16x^2 − 8x + 1 = 0
so in this case,
a = 16,  b = -8, c = 1

b^2 - 4ac
=(-8)^2 - (4 * 16* 1)
= 64 - 64
= 0
because it's equal 0, answer is one solution

Part B:

<span>4x^2 − 8x − 45 = 0
</span><span>solve the equation by factoring </span> 
= (2x - 9)(2x + 5)

set (2x - 9)(2x + 5) equal to 0 to solve for x
so
(2x - 9)(2x + 5) = 0
2x - 9 = 0
  x = 9/2
  x = 4.5

2x + 5 = 0
  x = -5/2
  x = -2.5
answer
x = -2.5 or x = 4.5

Hope it helps
