Answer:

D. naturalistic observation

Step-by-step explanation:

Naturalistic observation is a method of research that consists in observing subjects in their natural environment without any exterior interferences that could alter their behavior. By posing as a student, Dr. Jimand is inserting himself among the other students to observe their natural behavior. For instance, if they were told that there was a doctor observing them, the students' behavior could change and that wouldn't be a true naturalistic observation.

Can someone help me with this, please? I will give brainliest. Ridiculous answers will get reported.

Answer:

The reasoning here is that the price should be based on the volume.

for a cylinder it's pi * r² * height

for a cone it's 1/3 * pi * r² * height

you'll notice that the formulas are the same, except that the cone is just one third of the cylinders volume.

so a fair price should be 70ct, ignoring packaging of course.

What is a formula for the nth term of the given sequence? <br> 36, -48, 64...
stealth61 [152]

Answer:

A formula for the nth term of the given sequence is:

a_n=36\left(-\frac{4}{3}\right)^{n-1}

Step-by-step explanation:

Given the sequence

36, -48, 64...

We know that a geometric sequence has a constant ratio r and is defined by

a_n=a_1\cdot r^{n-1}

Compute the ratios of all the adjacent terms

\frac{-48}{36}=-\frac{4}{3},\:\quad \frac{64}{-48}=-\frac{4}{3}

The ratio of all the adjacent terms is the same and equal to

r=-\frac{4}{3}

Therefore, the given sequence is a geometric sequence.

As the first element of the sequence is

a_1=36

so substituting a_1=36 and r=-\frac{4}{3} in the nth term

a_n=a_1\cdot r^{n-1}

a_n=36\left(-\frac{4}{3}\right)^{n-1}

Therefore, a formula for the nth term of the given sequence is:

a_n=36\left(-\frac{4}{3}\right)^{n-1}

The shortest side of a right triangle measures 13 m. the lengths of the other two sides are consecutive integers. Find the lengt
mariarad [96]
So, the shortest side is 13, the other two fellows are two consecutive values.... ok... let's say the other leg is "a", a consecutive value to that will be a+1, so the hypotenuse is "a + 1" then

check the picture below

and surely you'd know what "a" is
