Answer:

There is approximately 5.475 liters of blood in the body.

Step-by-step explanation:

At a resting pulse rate of 75 beats per minute, the human heart typically pumps about 73 ml of blood per beat.

73 ml in liters = $73\times0.001=0.073$ liters

Now, 75 beats/min x 0.073 liters/beat = 5.475 liters/min

And 5.475 liters/min x 1 min/body = 5.475 liters/body

Hence, there is approximately 5.475 liters of blood in the body.

9966 [12]

Answer:

(-4,-19)

Step-by-step explanation:

y = x² + 8x - 3

y = x² + 2(x)(4) + 4² - 4² - 3

y = (x + 4)² - 16 - 3

y = (x + 4)² - 19

Vertex: (-4,-19)
