Answer:

The correct answer is -

a. the second group that receives test medicine

b. the first group that receives an inert pill

c. double-blind

d. placebo-controlled experiment

Step-by-step explanation:

a. The treatment group is the group that is used to test the experiment or change and receives the desire independent variable which is the second group that receives the test medicine along with an exercise and diet plan.

b. The control group is the group that is placed in ideal condition and receives no change other than placebo, here, the first group receives an inert pill along with the same exercise and diet plan.

c. Here neither the patients nor the fitness and nutrition advisors know which one is the control group and which one is the treatment group so ts a double-blind group.

d. This is best described as a placebo-controlled experiment due to the fact that there is a control group in this experiment that receives a placebo and another group that receives the treatment.

Are all of the vertical slices of a rectangular pyramid the same kind of shape? Explain your reasoning

Arte-miy333 [17]

If we slice the vertically the rectangular pyramid, we get a triangle with the base equal to the one of the dimensions of the rectangle, most probably the width. The height of the triangle, however, is dependent as to how far from the center is the slice cut off. Thus, the answer is same shape but of different sizes.

Given that f(x)= 2x+1 and g(x)= x^2 +2x+1 find (F+g)(2). Find (F.g)(x) find f(x)/g find f(2) +g(-2)?

Pepsi [2]

Answer:

$(f+g)(2) = 14$

$f(g(x)) = 2x^2 + 4x +3$

$\frac{f(x)}{g(x)} = \frac{2x+1}{x^2+2x+1}$

$f(2) + g(-2) = 6$

Step-by-step explanation:

Function composition and transformation combines functions together using operations such as addition, subtraction, multiplication, division and substitution. To find each, perform the operation with the functions f(x) = 2x+1 and $g(x) = x^2 + 2x +1$ .

(f+g)(x) is the functions f and g added together with 2 substituted for x.

$(f+g)(x) = 2x+1 + x^2 +2x + 1 = x^2 + 4x + 2\\(f+g)(2) = 2^2 + 4(2) + 2 = 14$

(f·g)(x) is function composition that means f(g(x)) or substitute g(x) into f(x).

$f(g(x)) = 2(x^2+2x+1)+1 = 2x^2 + 4x+2 + 1\\f(g(x)) = 2x^2 + 4x +3$

f(x) / g(x) is division of the two functions. Division can only occur with polynomials if they share the same factors or things which multiply to create them. If none are present, do not simplify.

$\frac{f(x)}{g(x)} = \frac{2x+1}{x^2+2x+1}$

This cannot be simplified.

f(2) + g(-2) means find the function value of f at 2 and the function value of g at -2 then add them together.

$f(2)+g(-2) = 2(2)+1 + ((-2)^2+2(-2) + 1)\\f(2) + g(-2) = 5 + (4-4+1)\\f(2) + g(-2) = 5 +1 = 6$

If A rectangular prism with a volume of 2 cubic units is filled with cubes with side lengths of 1/4. How many 1/4 unit cubes doe

PSYCHO15rus [73]

Answer:

It'll take 128 cubes to fill the prism.

Step-by-step explanation:

In order to solve this question we first need to find the volume of the cubes. The volume of a cube is given by the following formula:

volume = length³

So the cubes have the following volume:

volume = (1/4)³ = 1/64

Since we want to know how many of these cubes are needed to fill the prism, we need to divide prism's volume by the volume of the smaller cubes. We have:

number of cubes = (volume of prism)/(volume of cubes)

number of cubes = 2/(1/64)

number of cubes = 2*(64/1)

number of cubes = 128

It'll take 128 cubes to fill the prism.
