If c is a positive number, how many solutions does √x = c have? Explain.

Answers

Answer 1

Answer:

varied

square root of number never result negative number

Step-by-step explanation:

Answer 2

There will only be one real solution.

If [tex]x[/tex] is a real number, the square root function [tex]\sqrt x[/tex] will only have real solutions when [tex]x\ge0[/tex].

For [tex]x<0[/tex], we get imaginary solutions.

Also, when [tex]\sqrt x> 0[/tex], [tex]x>0[/tex]

In other words, when the square root of [tex]x[/tex] is a positive real number,  [tex]x[/tex] will be a unique positive number.

We can see this when trying to solve the equation given in the question

So, the equation

[tex]\sqrt x=c[/tex]

where [tex]c>0[/tex], when solved, will give

[tex]\sqrt x=c\\(\sqrt x)^2=c^2\\x=c^2[/tex]

We will have a unique solution because squaring a positive real number gives a single result.

D. Y = -0.994x+12.9

Answers

Answer: The answer is b !

Image attached should help

The line of best fit is:

y = 3.1x + 12.9

Option A is the correct answer.

We have,

The line of best fit can be expressed in the form of y = ax + b,

where a is the slope of the line and b is the y-intercept.

From the given LinReg results, we have:

a = 3.1

b = 12.9

Substituting a and b in the equation y = ax + b we get,

The line of best fit is:

y = 3.1x + 12.9

Thus,

The line of best fit is:

y = 3.1x + 12.9

Answer:

A box-and-whisker plot. The number line goes from 25 to 50. The whiskers range from 27 to 48, and the box ranges from 32 to 45. A line divides the box at 36.

Step-by-step explanation:

Given the five number summary which are all displayed on a box and whisker plot :

Maximum = 48

Minimum = 27

Median = 36

Upper Quartile = 45

Lower quartile = 32

Maximum and minimum values are displayed by the whiskers :

Starting point of whisker = minimum value

End point of whisker = maximum value

The quartiles are displayed by the box :

Starting point of the box = lower quartile

End point of the box = upper quartile

Line in between the box = Median

Coordinates of Joe's home = (2, 3)

Coordinates of the park = (1, 1)

The shortest distance = the distance between the two points

Use distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex] to calculate the shortest distance.

Where,

[tex] (2, 3) = (x_1, y_1) [/tex]

[tex] (1, 1) = (x_2, y_2) [/tex]

Plug in the values into the formula

[tex] d = \sqrt{(1 - 2)^2 + (1 - 3)^2} [/tex]

[tex] d = \sqrt{(-1)^2 + (-2)^2} [/tex]

[tex] d = \sqrt{1 + 4} [/tex]

[tex] d = \sqrt{5} [/tex]

[tex] d = 2.2 [/tex] (nearest tenth)

Answer:

No of hits = 26

Step-by-step explanation:

Given that,

Batting average = 0.4727272

His player has 55 at bats.

We need to find the number of hits. Let the number of hits be x. Using formula for average as :

[tex]\dfrac{x}{55}=0.4727272\\\\x=0.4727272\times 55\\\\x=25.99\\\\or\\\\x=26[/tex]

Of the marbles in a​ bag, 5 are blue​, 2 are white​, and 2 are yellow. Sandra will randomly choose one marble from the bag.

Answers

Answer:

[tex]\dfrac{2}{9}[/tex]

Step-by-step explanation:

Given that,

A bag contains 5 blue, 2 white and 2 yellow marbles.

We need to find the probability of choosing a white marble from the bag.

Total no. of outcomes = 5+2+2

= 9

No. of white marbles = 2

Required probability,

[tex]P=\dfrac{2}{9}[/tex]

So, the probability of choosing a white marble is equal to [tex]\dfrac{2}{9}[/tex].
