Answer:

h(g(-5)) = 127

Explanation:

Given

h(x) = 2x^2 - 1

g(x) = x - 3

Required

Find h(g(-5))

First, we need to solve for g(-5)

g(x) = x - 3

Substitute -5 for x

g(-5) = -5 - 3

g(-5) = -8

Substitute -8 for g(-5) in h(g(-5))

h(g(-5)) = h(-8)

Given that:

h(x) = 2x^2 - 1

Substitute -8 for x

h(-8) = 2(-8)^2 - 1

h(-8) = 2*64 - 1

h(-8) = 128 - 1

h(-8) = 127

Hence:

h(g(-5)) = 127

Dr. Whitlock is conducting an experimental study on the effectiveness of antipsychotic medication Which of the following will mo
NemiM [27]

Answer:

D Serotonin levels, because this is the variable she is measuring .

Explanation:

Dr. Whitlock is looking for the effectiveness of the medication.

A. is incorrect because it say the type of medicationn was being manipulated if this were true this would be the independent variable (the thing the scientist or person changes)

So just by knowing why A is wrong we can automatically rule out

A.

C. and

E.

That leaves B. and D. giving you 50/50 chance of being correct if this were on an actual test/EOC.

I am a little unsure of if it would be B or D at first so I decided to leave some information for you in case you disagree or want to check I'll leave it up to you to officially decide if it's B or D but I personally believe it's D. here's the information:

You can Eliminate B. because Dr. Whitlock is looking for the effectiveness of the medication and D. is talking about the serotonin levels, serotonin affects your mood, low serotonin levels can cause depression. But if serotonin effects your mood is that something a anti-psychotic medicine be prone to fixing or would it be the hallucinations? which many experience but do the serotonin levels effect your sanity more than the auditory hallucinations, cause people can have inaudible hallucinations.

I may be looking into to this WAY too much and OVER thinking it but I hope this at least helped you a bit giving you a 50/50 chance of getting this right. Sorry if this is confusing.

( I found the same question but with the letter options thats how I know the options and how I ruled out some)

What issues may arise if nominal gross domestic product was used instead of real gross domestic product?
AVprozaik [17]

Answer: See explanation

Explanation:

Real gross domestic product is simply refered to the economic output of a particular country which has been adjusted for price changes as inflation was taken into consideration.

Nominal gross domestic product is the measurement of the gross domestic product of a particular country which makes use of current prices, and isn't inflation adjusted.

The issue that may arise when nominal gross domestic product was used instead of real gross domestic product is that the nominal GDP leads to the inflation of the growth figure in the economy. This is because the nominal GDP doesn't take inflation into effect.

This leads to the misleading of the GDP since there'll be an overstatement of the GDP even though it was actually a rise in the inflation rate for the particular economy.
