Question

I need math help. I don’t understand the question.

Answer 1

Answer:

A.) 132.3 mm Hg

B.) 49 years old

Step-by-step explanation:

$P= 0.006y^{2} -0.01y+119$

P = blood pressure

y = age in years

A.) Solution

To find: P

Given: y = 48

$P= 0.006y^{2} -0.01y+119$

P = 0.006 x 48 x 48 - 0.01 x 48 + 119

P = 0.006 x 2,304 - 0.48 + 119

P = 13.824 - 0.48 + 119

P = 132.344 ⇒ 132.3

B.) Solution

To find: y

Given: P = 132.92

$P= 0.006y^{2} -0.01y+119$

$132.92= 0.006y^{2} -0.01y+119$

$0.006y^{2} -0.01y-13.92$
