<u>Trigonometry</u>

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

  • a is a leg
  • b is another leg
  • c is the hypotenuse<u> </u>

Step-by-step explanation:

<u>Step 1: Define</u>

Leg <em>a</em> = 8

Leg <em>b</em> = 4

Hypotenuse <em>c</em> = <em>x</em>

<em />

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute in variables [Pythagorean Theorem]:                                            8² + 4² = x²
  2. Evaluate exponents:                                                                                         64 + 16 = x²
  3. Add:                                                                                                                   80 = x²
  4. [Equality Property] Square root both sides:                                                    √80 = x
  5. Rewrite:                                                                                                             x = √80
  6. Simplify:                                                                                                             x = 4√5

Write down the first three terms of the sequence whose nth term is given by 2n-5
likoan [24]

Answer:

- 3, - 1, 1

Step-by-step explanation:

To find the first 3 terms substitute n = 1, 2, 3 into the formula

a₁ = 2(1) - 5 = 2 - 5 = - 3

a₂ = 2(2) - 5 = 4 - 5 = - 1

a₃ = 2(3) - 5 = 6 - 5 = 1

The first 3 terms are - 3, - 1, 1

Svana wants to solve the equation x - 1.0675 = 3x - 4145.
AysviL [449]

Answer: D

Step-by-step explanation:

Given that Svana wants to solve the equation 1/2x - 1.0675 = 3x - 4145.

This equation is a system of equations which can be solved by using simultaneous equation methods.

But if she uses a graphing program to graph the equations y = 1/2x - 1.0675 and y = 3x - 4.145

The solution of 1/2x - 1.0675 = 3x - 4.145. Will be the point of intersection of the two equation.

Trace the point of intersection to the x - axis and also to the y - axis.

The solution to the system of equations is ( 1.231, - 0.452 )

Determine whether the forces in the pair are pulling at right angles to each other.
snow_tiger [21]
Given:
right triangle
a = 2.9
c = 4.2

Pythagorean Theorem: a² + b² = c²

missing value of b.

b² = c² - a²
b² = (4.2)² - (2.9)²
b² = 17.64 - 8.41
b² = 9.23
b = √9.23
b = 3.03 or 3.0 

The value of b is 3.0
