Which equation is related to √x+10-1=x ? The square root is over the x+10
Sergio [31]

Answer:

  (b)  x + 10 = x^2 + 2x + 1

Step-by-step explanation:

The equation can be transformed to one without the radical by isolating the radical and squaring both sides.

__

  \sqrt{x+10}-1=x\qquad\text{given}\\\\\sqrt{x+10}=x+1\qquad\text{add 1 to both sides}\\\\x+10=(x+1)^2\qquad\text{square both sides}\\\\\boxed{x+10=x^2+2x+1}\qquad\text{eliminate parentheses}

_____

<em>Additional comment</em>

In typeset formulas, radicals, fraction bars, and superscript formatting serve to group expressions. In plain text, the only available grouping symbol is parentheses.

  \sqrt{x+1}}\ \Rightarrow √(x+1)

Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan’s father and paternal grandfather were all
Helga [31]

The probability that Nathan is not allergic to penicillin, like his father and paternal grandfather, is <u>24.5%</u>.

<h3>What is probability?</h3>

Probability estimates the likelihood of an event occurring.

Probability is expressed as a percentage, decimal, or fraction, and must be less than or equal to one.

<h3>Data and Calculations:</h3>

Nathan's chances of having the same allergy = 75%

Nathan's probability of not having the same allergy = 25% (1 - 75%)

Accuracy of test performed by the doctor = 98%

The probability that Nathan is not allergic to the drug after the test = 24.5% (25% x 98%).

Thus, the probability that Nathan is not allergic to penicillin is <u>24.5%</u>.
