Explain why you cannot square each side of the equation when verifying a trigonometric identity.
Sergeu [11.5K]
This is because when we do verification of an identity, we must work separately on both sides, and to see in the end if we can get an equality. Because if we square both sides, that already means that we assume that the equality exist in the beginning, so no need to verify the identity.

The red blood cell counts​ (in millions of cells per​ microliter) for a population of adult males can be approximated by a norma
skad [1K]

Answer:

(a) Minimum red blood cells 5.744 million cells per micro liter

(b) Maximum red blood cells 5.068 million cells per micro liter.

Step-by-step explanation:

Z-score formula is = \frac{x-u}{Standard deviation}

Z-score = \frac{x-5.5}{0.4}

The value of z-score is 0.61 so then x will be;

x = 5.744

The minimum red blood cells count that can in top is 27% of count which is 5.744 million cells per micro liter.

Z-score = \frac{x-5.5}{0.4}

The value of z-score is 0.14 so then x will be;

x = 5.068

The maximum red blood cells count that can be in top is 14% of count which is 5.068 million cells per micro liter.

Kipish [7]

Answer:

n = \frac {p - 4m}{m}

Step-by-step explanation:

Given the algebraic expression;

m = \frac {p}{n + 4}

To make n the subject of formula.

Cross-multiplying, we have;

m*(n+4) = p

mn + 4m = p

Rearranging the equation, we have;

mn = p - 4m

n = \frac {p - 4m}{m}
