Answer:

16π

Step-by-step explanation:

Given:

[tex]\text{Radius of circle}: 4 \ \text{m}[/tex]

Formula:

[tex]\text{Area of circle} = \pi r^{2}[/tex]

Replace the radius in the formula:

[tex]\implies \text{Area of circle} = \pi (4)^{2}[/tex]

Evaluate the area:

[tex]\implies \text{Area of circle} = \pi (4)(4)[/tex]

[tex]\implies \text{Area of circle} = 16\pi[/tex]

Since the question says to determine the area in terms of π, the final answer is 16π.

The right triangle with sides 29m, 49.5m and 57.4 m has the value of cot  φ as 1.707

A right angle triangle has one of its angles as 90 degrees.

Therefore, it has an opposite, adjacent and hypotenuse side depending on the angle.

oposite side = 29 m

adjacent side = 49.5 m

hypotenuse side = 57.4 m

Therefore,

cot φ = 1 / tan φ

Hence,

tan φ = opposite / adjacent

Therefore,

cot φ = adjacent / opposite

cot φ = 49.5 / 29

cot φ = 1.70689655172

cot  φ =  1.707

Step-by-step explanation:

0) the common formula is:

area=π*r²;

1) according to the formula above the area of the sector C. doubles (increases by a factor two);

2) according to the formula the area of the sector D. quadruples (increases by a factor four).

The volume of the large sphere shown in the image is, 1/27 times the volume of the small sphere.

Volume of sphere is the amount of quantity, which is obtained by the it in the 3 dimensional space.

The volume of the sphere can be given as,

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

Here, (r) is the radius of the sphere.

The radius of the large sphere is times longer than the radius of the small sphere. Here in the attached image,

The ratio of the volume of the large sphere to the volume of the small sphere is,

[tex]\dfrac{V_l}{V_s}=\dfrac{\dfrac{4}{3}\pi (18.6)^3}{\dfrac{4}{3}\pi (6.2)^3}\\\dfrac{V_l}{V_s}=\dfrac{18.6\times18.6\times18.6}{6.2\times6.2\times6.2}\\\dfrac{V_l}{V_s}=\dfrac{1}{27}[/tex]

Thus, the volume of the large sphere shown in the image is, 1/27 times the volume of the small sphere.

Answer:

Then the vertex is at (h, k) = (2, –3) and the value of p is –3. Since y is squared and p is negative, then this is a sideways parabola that opens to the left. This puts the focus 3 units to the left of the vertex.

vertex: (2, –3); focus: (–1, –3)

Answer:

George : Carl : Alex = 1 : 12 : 4

Step-by-step explanation:

let a = Alex's age in years

let g = George's age in years

let c = Carl's age in years

Given:

⇒ a = 12 + g

⇒ g = a - 12

Given:

⇒ c = 3a

Given:

⇒ a + g + c = 68

Substitute the first two equations in the last equation and solve for a:

⇒ a + (a - 12) + 3a = 68

⇒ 5a - 12 = 68

⇒ 5a = 80

⇒ a = 16

Substitute the found value of a into the other equations to find g and c:

⇒ g = 16 - 12 = 4

⇒ c = 3(16) = 48

Therefore:

Ratio

George : Carl : Alex = 4 : 48 : 16

Reduce by dividing by 4 → 1 : 12 : 4

Answer:

The first one is blinded. I didn't get the other one though. The one that says "neither the subjects nor the researchers" is wrong.

Step-by-step explanation:

I use Plato.

The experiment is blindeded because the scientist know which treatment group each subject is in.

Experiment is the scientific approach to determine the properties of some sample by doing some research on it eg. By adding another material, or determination of hypothesis.

Hypothesis is the assumption which is made under some evidence which can be proceed further verification or by doing experiment on it.

From the question it is clear that the scientist wants to meassure the effect of apple cider vinegar subject on the blood sugar level.

So here the effect of apple cider vinegar subject on the blood sugar level is hypothesis.

From 200 randomly choosen young groups one half have taken apple cider where other half have taken placebo in order to clarify and study which group has taken which treatment and their effect in their blood sugar level.

Answer:

c)

Step-by-step explanation:

Answer: C) (12, -14)

Step-by-step explanation:

I am going to solve by elimination.

Start by subtracting one equation from the other

[tex]y=-x-2\\-(y=-\frac{1}{2} x-8)\\0=-\frac{1}{2} x+6[/tex]

Now solve for x

[tex]0=-\frac{1}{2} x+6\\0-6=-\frac{1}{2} x+6-6\\-6=-\frac{1}{2} x\\(-6)(-2)=(-2)(-\frac{1}{2} x)\\12=x[/tex]

Now sub in x into one of the equations to find the value of y

[tex]y=-(12)-2\\y=-14[/tex]
