A quadrilateral in which opposite sides are parallel is called a parallelogram. The correct option is A.

<h3>What is a parallelogram?</h3>

A quadrilateral in which opposite sides are parallel is called a parallelogram. Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.

For a parallelogram, the pair of opposite sides are equal and parallel. Therefore,

1.)  For the first pair.

(x+8) = 15

x = 7

2.) For the second pair

(x+2)=(2x-5)

x + 2 = 2x - 5

2 + 5 = 2x - x

x = 7

(x+2) = (7+2) = 9

Since the measure of the pair of opposite sides is 15 units, the pair of the other two sides measure 9 units.

Hence, the correct option is A.

The complete question is mentioned in the below image.

    (4, 1)            3*4 - 11 = 1       10y = 10*1 = 10 ....... not correct

   (6, 0.7)        3*6 - 11 = 7       10y = 10*0.7 = 7  .....Correct

   (8,2.3)          3*8 -11 = 13       10y = 10*2.3 =23   ..... not correct

   (10, 1.9)        3*10 -11 = 19       10y = 10*1.9 = 19   .... correct

At the moment a certain medicine is injected, its concentration in the bloodstream is 120 milligrams per liter.
igomit [66]

Answer:

c(t) = 120 [0.7]^{t}

Step-by-step explanation:

At the moment a certain medicine is injected, its concentration in the bloodstream is 120 milligrams per liter.

From that moment forward, the medicine's concentration drops by 30% each hour.

Therefore, the medicine concentration c(t) in mg/liters after t hours will be modeled as

c(t) = c(0) [1 - \frac{30}{100}]^{t}

⇒ c(t) = c(0) [1 - 0.3]^{t} 

⇒c(t) = 120 [0.7]^{t} . (Answer)
