How would I know the domain and range? - Algebra 2

kvv77 [185]

Domain: Set of all real numbers

Range: $-1 \le y \le 1$ where y is a real number

---------------------------------------------------

The domain is the set of real numbers because there are no restrictions on what to plug in for x. There are no gaps, holes, jumps, or asymptotes. The graph continues on in both directions stretching to both infinities (this is indicated by the arrows on the curve ends)

The range is the set of y values between -1 and 1 because this is the set of y outputs. The largest y can get is +1 or just 1. The smallest y can get is -1. The value of y can be any number in between as there are no gaps.

Rewrite <img src="https://tex.z-dn.net/?f=%5Csqrt%7Bn%5E%7B3%7Dp%5E%7B4%7D%20%20%7D" id="TexFormula1" title="\sqrt{n^{3}p^{4} }

Answer:

${n}^{1\frac{1}{2}}{p}^{2}$

Step-by-step explanation:

According to the Definition of Rational Exponents, use this formula to rewrite this as an exponential expression:

$a^{\frac{m}{n}} = \sqrt[n]{a}^{m}$

NOTE: Since we have exponents in our radical, we have to multiply all exponents by one-half, since raising something to its half power is the exact same as taking the square root of something:

$[{n}^{3}{p}^{4}]^{\frac{1}{2}} = {n}^{1\frac{1}{2}}{p}^{2}$

* Do not forget to remove the radical in the beginning because you are once again, rewriting this as an exponential expression.

A faucet in a large tank can fill the tank in 12 hours. However, there is a hose in the tank which would be able to empty the ta

Kruka [31]

It would take the faucet 18 hours to fill the tank because 18/12=1.5. That means it will be 1.5 times slower to fill the tank up with the hose on. 1.5*12=18.

A health department spokesman speaking on a local radio station has advocated that parents download a particular app on their ph

maria [59]

Answer:

Option E is correct.

There seems to be a relationship between the app and preventing the spread of daycare illness.

Step-by-step explanation:

The study was carried out on a sample size of 1200 randomly selected parents and it was discovered that children of parents who downloaded the app, on average, had 10 fewer cases of daycare-related illness during the study period than those whose parents did not download the app.

Examining the options one at a time

a. Because downloading the app seems to decrease child illness, the app should be effective for decreasing child neglect as well.

The study showed that downloading the app seemed to truly decrease daycare-related illnesses in children, but it does not mention anything about child neglect. Hence, this is not a correct conclusion for the study.

b. Downloading the app will cause daycare workers to not spread germs.

The study did not in any way study how the app works, whether it prevents daycare workers to not spread germs, so, this conclusion seems like jumping the gun. It isn't an accurate conclusion of what the study did.

c. The study was an experiment rather than an observational study.

The study was actually more of an observational study. An observational study involves the researchers taking notes and recording the effects of a particular variable or lack of thereof, without interfering with the study.

d. The sample size of the study was too low to determine a result.

A sample size of about 1200 is a large enough sample for the sample characteristics to reflect the population characteristics. So, this statement too isn't true.

e. There seems to be a relationship between the app and preventing the spread of daycare illness.

Based on this information given, it is evident that the results of this study shows a relationship between the app. It shows a significant decrease in daycare-related illnesses in children of parents who downloaded the app. Hence, the app must have something that reduces the chances of a daycare-related illness in the children of parents who downloaded the app.

Hope this Helps!!!
