HOW DO I FIND QR<br><br> PLEASE HELP
Paul [167]

Solution: For finding QR we need to apply Pythagoras Theorem

What is Pythagoras Theorem ?

ans : Pythagoras Theorem is the sum of square of two sides which is equal to the third side or the hypotenuse. This formula is valid oy incase of Right-Angled Traingle because one of three angles here is 90°

According to this law let's apply it in the diagram shown here.

  • (Hypotenuse)² = (Adjacent)² + (Opposite)²

  • (PR)² = (QR)² + (PQ)²

  • (5x - 2)² = (QR)² + (3x - 1)²

  • (QR)² = (5x - 2)² - (3x - 1)²

After factorising both of them we get

  • (QR)² = 25x² - 20x + 4 - (9x² - 6x + 1)

  • (QR)² = 25x² - 20x + 4 - 9x² + 6x - 1

  • (QR)² = 16x² - 14x + 3

  • QR = √(16x² - 14x + 3)

So, QR is √(16x² - 14x + 3)

PLZ HELP, DUE TONIGHT!! Find the values of a and b such that f(x) is continuous at x=1
Sedaia [141]

Answer:

  • a = 2, b = -4

Step-by-step explanation:

<u>To make the given piecewise function continuous we need:</u>

  • ax² - b = 6 and 5ax + b = 6 at x = 1

<u>It gives us the system:</u>

  • a(1²) - b = 6 ⇒ a - b = 6
  • 5a(1) + b = 6 ⇒ 5a + b = 6

<u>Sum of the two:</u>

  • a - b + 5a + b = 6 + 6
  • 6a = 12
  • a = 2

<u>Then b is:</u>

  • 2 - b = 6
  • b = -4
