Answer:

Step-by-step explanation:

We will have to open the bracket first followed by collecting the like terms

Open the bracket first

5(x+3)=4(x-3)

5x+15=4x-12

Collect like terms

5x-4x=-12-15

x=-27

So the final answer is-27

A group of researchers wants to develop an experiment to determine whether a new drug effectively treats hypothyroidism. The res
Rashid [163]

Some possible ethical issues to this type of testing that they are subjected to unpleasant and hazardous procedures, as well as stress and injury.

<h3>What is experiment?</h3>

Any well-defined method that yields an observable outcome that cannot be precisely predicted in advance is referred to as a experiment. To avoid any ambiguity or surprise, a experiment must be properly defined.

A) Because human experimentation is immoral, animal research has been employed as a research approach.

However, using animals is unethical because they are subjected to unpleasant and hazardous procedures, as well as stress and injury. The use of non-animal methods to substitute animal methods as much as possible will provide both ethical and technical benefits. Researchers should make the use of non-animal methods for a top priority experiments.

B) Even though the purpose of an experiment is to ensure success in rabbits, this is incorrect in people because action is what will operate properly.

The absence of thyroid-stimulating hormone in rabbit serum is a mistaken notion. As a result, it is preferable to test the drug further, and it was a success. As a result, there will be no dysfunctionality for humans.

Thus, some possible ethical issues to this type of testing that they are subjected to unpleasant and hazardous procedures, as well as stress and injury.

Find the final amount. ​$4000 invested at 11​% APR compounded quarterly for 5 years The final amount is ​$ nothing. ​(Do not rou
Angelina_Jolie [31]
<h3>The final amount is $ 6881.71</h3>

<em><u>Solution:</u></em>

<em><u>The formula for compound interest, including principal sum, is:</u></em>

A = p(1 + \frac{r}{n})^{nt}

Where,

A = the future value of the investment

P = the principal investment amount\

r = the annual interest rate in decimal

n = the number of times that interest is compounded per unit t

t = the time the money is invested

From given,

p = 4000

t = 5

r = 11 \% = \frac{11}{100} = 0.11

n = 4 ( compounded quarterly )

<em><u>Substituting the values in formula,</u></em>

A = 4000(1 + \frac{0.11}{4})^{4 \times 5}\\\\ A = 4000( 1.0275)^{20}\\\\A = 4000 \times 1.720428\\\\A = 6881.7137 \approx 6881.71

Thus the final amount is $ 6881.71
