A formula for the normal systolic blood pressure for a man age A, measured in mmHg, is given as P=0.006 A2 -0.02A + 120. Find the age to the nearest year of a man whose normal blood pressure measures 125
mmHg.

The age to the nearest year of a man whose normal blood pressure measures 125  mmHg is; A = 31 years

P = 0.006A² - 0.02A + 120

Where;

P is normal systolic blood pressure

A is age of the man

125 = 0.006A² - 0.02A + 120

Using subtraction property of equality gives;

125 - 125 = 0.006A² - 0.02A + 120 - 125

0 = 0.006A² - 0.02A - 5

Using online quadratic equation solver gives;

A = 30.5823 or -27.2489

Age cannot be negative and so we take the positive one as;

A = 30.5823

Approximation to the nearest year gives;

A = 31 years

211 years

Step-by-step explanation:

A formula for the normal systolic blood pressure for a man age A, measured in mmHg, is given as

....(1)

We need to find the age to the nearest year of a man whose normal blood pressure measures 125  mmHg.

Put A = 125 mmHg in the given equation.

So, the nearest age of a man is 211 years.

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
