\text{Hey there!}

\text{49}=\sqrt{\text{x}}\\\\\text{Reverse the equation:}\sqrt{\text{x}}=49

\text{After you reverse the equation put the square root on each of your sides!}

\text{In order for you to find the outcome (your result) put 49 to the power of 2 (49)}^2

\text{Your equation becomes:x = 49}^2

\text{49}^2\text{= 49}\times49 =2,401

\boxed{\boxed{\bf{Thus, your\ answer\ is: 2,401}}} \checkmark

\text{Note: there's many ways that you could solve for these type of problems but} \text{steps are basic for better understanding the particular equation!}

\text{Good luck on your assignment and enjoy your day!}

A(n) ___________________ variable is a qualitative variable such that there is no meaningful ordering or ranking of the categori
Licemer1 [7]

Answer: c. Nominal

Step-by-step explanation:

Level of measurement determines the nature of description .

The four levels of measurements scales are

1. Nominal scale

  • Categorize the data on the basis of the quality such as Gender, color, etc.

2. Ordinal scale

  • Order attributes according to their ranks. For example : 1 < 2 < 3 .

3. Interval scale

  • Describe the feature of the difference between any two categories. For example : Fahrenheit scale to measure temperature.

4. Ratio scale

  • Consist of the features of nominal, ordinal, and interval measures but in includes a "true zero" point.

For example : Age.

∴ A<u> nominal</u> variable is a qualitative variable such that there is no meaningful ordering or ranking of the categories.

Hence, the correct answer is c. Nominal .

the population of mastertown was 23,000 in 2012. assume that mastertowns population increased at a rate of 2% per year. write an
vazorg [7]
Exponential growth is

F=P(1+r)^t
F=future amount
P=present amount
r=rate
t=time in years

rate=2%=0.02
therefor the equation is
f(x)=23,000(1+0.02)^x
f(x)=23,000(1.02)^x
where x=time in years from 2012

Can you help me with my work
andrezito [222]

Answer:

1. x = ±9

2. x=\pm \sqrt{13}

3. 12 and -12.

4. Antoine is incorrect. There exists two solutions x=5 and x= -5.

Step-by-step explanation:

According to the questions,

Problem 1. x^{2}-81=0 i.e. x^{2}=81 i.e. x = ±9.

Problem 2. 2x^{2}-26=0 i.e. x^{2}-13=0 i.e. x^{2}=13 i.e. x=\pm \sqrt{13}

Problem 3. [tex]f(x)=x^{2}-144[tex]

To find the roots, we take, [tex]x^{2}-144=0[tex] i.e. [tex]x^{2}=144[tex] i.e. x = ±12.

Thus, the options are 12 and -12.

Problem 4. We have [tex]f(x)=x^{2}+25[tex]

For the roots, we take, [tex]x^{2}+25=0[tex] i.e. [tex]x^{2}=25[tex] i.e. x = ±5.

Thus, Antoine is not correct and two solutions namely x=5 and x= -5 exists.

write a linear equation that has a slope of 1/2 and a y-intercept at the origin. (y=1/2x) (y=0x+1/2) (y=1/2x+1/2) (y=-1/2x)​
Nesterboy [21]

Answer:

The linear equation with given slope and y-intercept is:

Option 1: y = \frac{1}{2}x

Step-by-step explanation:

The slope-intercept form of equation is given by:

y = mx+b

Here

m is the slope of the line and b is the y-intercept.

Given that

Slope of line is 1/2 so m = 1/2

And y-intercept is on origin so b = 0

Putting the values we get

y = \frac{1}{2}x+0\\y = \frac{1}{2}x

Hence,

The linear equation with given slope and y-intercept is:

Option 1: y = \frac{1}{2}x
