Answer:

The concentration of antibiotic after 4 hours will be 11.04 ppm (parts per million).

Step-by-step explanation:

Given that the concentration of antibiotics after h hours can be given by the polynomial:

-0.06h^2+2h+4=A(h)

For h=4, equation will be:

-0.06 (4)² + 2 (4)+4= A (4)

11.04 = A (4)

The concentration of antibiotic after 4 hours will be 11.04 ppm (parts per million).

Answer:

m∠QPT = 110°

Step-by-step explanation:

1. We can use exterior angle theorem to find m∠QPT. Exterior Angle Theorem states that the exterior angle of a triangle is equal to the sum of the two remote angles in that same triangle.

  • This means that 6x + 20 = x + 40 + 4x - 5. Then, we can plug in the value of x into 6x + 20 and find the measure of ∠QPT.

2. (Solving)

Step 1: Combine like terms.

  • 6x + 20 = (x+4x)+(40-5)
  • 6x + 20 = 5x + 35

Step 2: Subtract 20 from both sides.

  • 6x + 20 - 20 = 5x + 35 - 20
  • 6x = 5x +15

Step 3: Subtract 5x from both sides.

  • 6x - 5x = 5x +15 - 5x
  • x = 15

Step 4: Check if solution is correct.

  • 6(15)+20=(15)+40+4(15)-5
  • 90 + 20 = 15 + 40 + 60 - 5
  • 110 = 55 + 60 - 5
  • 110 = 115 - 5
  • 110 = 110

3. Now, let's plug in 15 for 6x + 20:

  • 6(15)+20
  • 90+20
  • 110

Therefore, m∠QPT = 110°.
