a polynomial function has -5<img src="https://tex.z-dn.net/?f=%5Csqrt%7B3t%7D" id="TexFormula1" title="\sqrt{3t}" alt="\sqrt{3t}

Goshia [24]

Answer:

$5 \sqrt{3}i$

Step-by-step explanation:

Assuming one root of a polynomial function is

$- 5 \sqrt{3} i$

Then the other root is

$5 \sqrt{3}i$

The reason is that , complex roots of polynomial functions occur in pairs.

One complex root is the conjugate of the other.

This means that, if

$x - yi$

is a root, then

$x + yi$

is also a root.

Sally has completed 1/3 of her shift; Jerry has completed 5/6 of his shift; David has finished 1/2 of his shift; Mona has 7/8 of

Step2247 [10]

Sally = 1/3
Jerry = 5/6
David = 1/2
Mona = 1 - 7/8 = 1/8

So, the biggest fraction among them is 5/6.

Jerry has completed the most work time.

Claim: Most adults would not erase all of their personal information online if they could. A software firm survey of 677 random

Alika [10]

Answer: The value of test statistic is -0.052.

Step-by-step explanation:

Since we have given that

n = 677

and

$\bar {p}=0.499$

Claim that Most of the adults erase all of their personal details online.

p = 0.5

q = 1-0.5 = 0.5

So, the test statistic would be

$z=\dfrac{\bar{p}-p}{\sqrt{\dfrac{pq}{n}}}\\\\z=\dfrac{0.499-0.5}{\sqrt{\dfrac{0.5\times 0.5}{677}}}\\\\z=\dfrac{-0.001}{0.0192}\\\\z=-0.052$

What is the coefficient in the mathematical expression?

barxatty [35]

Using it's concept, it is found that the coefficient of the mathematical expression 7m² + 2(19) is of 7.

<h3>What is the leading coefficient of a polynomial?</h3>

The leading coefficient of a polynomial is the <u>term that multiplies the highest exponent</u>.

In this problem, the expression is given by:

7m² + 19.

The highest exponent is of 2, in m², hence the leading coefficient is of 7.
