A huge rotating patch of particles in space drift together to form an increasingly dense ball. as it shrinks in size, the cloud _______.
A huge rotating patch of particles in space drifts together to form an increasingly dense ball. As it shrinks in size, the cloud rotates faster.
What is gravity?Gravity is a physical property of the matter associated with the attraction of objects to each other, which can increase the density by speeding up such objects.
The gravity of our star (Sun) maintains all the planets of the solar systems in a constant and stable orbit.
Subsequently, planets have their own gravity that allows them to attract minor objects such as satellites.

The finishing times of a 5k race run by competitive male runners age 15-18 are approximately normal distribution with a mean time of 18 minutes and a standard deviation of 2 minutes. a particularly tough 5k race tends to take these same runners 4.5 additional minutes. to earn a completion medal in this particular 5k race, the runner must complete the race within 25 minutes. approximately, what percent of competitive male runners in the 15-18 age bracket typically do not earn a completion medal at this race?
Using the normal distribution, it is found that 0.1056 = 10.56% of runners do not earn the competition medal.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.In this problem, considering the 4.5 additional minutes, the mean and the standard deviation are given, respectively, by:
[tex]\mu = 22.5, \sigma = 2[/tex].
Runners that take more than 25 minutes to complete the race do not earn a medal, hence the proportion is one subtracted by the p-value of Z when X = 25, so:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{25 - 22.5}{2}[/tex]
Z = 1.25
Z = 1.25 has a p-value of 0.8944.
1 - 0.8944 = 0.1056.
0.1056 = 10.56% of runners do not earn the competition medal.

Lesson 14.1 distance in the coordinate plane answer key
The distance formula, [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex], is used to find the distance between two points on a coordinate plane.
What is the Distance Formula?The distance formula, [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex], is used to find the distance between two points on a coordinate plane.
For example, given the following points on a coordinate plane:
A(2, 3) - (x1, y1)B(5, 6) - (x2, y2)Using the distance formula, we would calculate the distance as:
AB =√[(5−2)² + (6−3)²]
AB = √[(3)² + (3)²]
AB = √18

In order to figure out the distance, what do I do?
Answer:
d = square root of {(x2 - x1)^2 + (y2-y1)^2}
Explanation:
If you're referring to math-
the distance is equal to (the second x value minus the first x value)^2 plus (the second y value minus the first y value)^2
For example: this is my imaginary ordered pair, I want to find the distance between the points- (2,4) and (3,6)
So d= (3-2)^2 - (6-4)^2 all under a square root
3-2 is = to 1, and 1 squared is just 1.
6-4 is = to 2, and 2 squared is 4.
4+1 is = 5.
So your answer would be the square root of 5.
If your answer ended up as, for example, the square root of 16, you would go a step further and your answer, or distance would be 4, since 4^2 is 16
Math accelerated chapter 11 congruence similarity and transformations answers
An example of congruence similarity and transformations work is " If the measures of the angles of a triangle are in the ratio 4 : 5 : 9. The triangle is?.
What is right angled triangle?A right triangle is known to be often called right-angled triangle. It is said to be a triangle that is composed of one angle which is at a right angle and two sides which are said to be perpendicular.
So lets take the angles to be 4x, 5x and 9x
We add them to be 4x + 5x + 9x =180°
18x=180° =
x= 180/18
x = 18
So therefore the angles are:
4×10°
=40°
5×10°
=50°
9×10°
=90°
So therefore since one of the angle is 90° and as such, the triangle is right angled triangle.

A 20.0-ml sample of a 0.200 mhbr solution is titrated with a 0.200 mnaoh solution. calculate the ph of the solution after the following volumes of base have been added.
The calculated pH of the solutions are given below:
The pH of the solution after 14.0 ml of base is added to it is calculated as 1.45. The pH of the solution after 19.8 ml of base is added to it is calculated as 3.0The pH of the solution after 20.0 ml of base is added to it is calculated as 7. What is pH?This is the level of acidity or alkalinity of an aqueous solution. The pH of a substances tells if its an acid, base or neutral.
HBr and NaOH while in water would dissociate and they would become H+ and OH- respectively.
Mol of HBr = Mol * Vol
= 0.200 * 20mL
= 4 mmol
A. Moles of NaOH added
= 0.2 X 14
= 2.8 mmol
Moles of H+ that did not react
= 4 - 2.8
= 1.2 mmol
1.2/1000 = 0.0012 moles
Total volume = 20 + 14
= 34 mL to litres
= 0.034 L
Molarity of H+ = 0.0012 / 0.034L
= 0.035 M
-log[0.035] = 1.45
The pH of the solution is 1.45
B. NaOH added = 19.8 * 0.2 =
3.96 mmoles
The unreacted solution
= 4.0 - 3.96
= 0.04 mmol
0.04/1000 = 0.00004 moles
Total volume = 20 + 19.8
= 39.8mL
Converted to litres = 0.0398L
Molarity = 0.00004 / 0.0398L
= 0.001
-log(0.001) = 3.0
The ph Is therefore 3.0
C. Moles of NaOH added = 0.2*20mL = 4mmol
All the H+ are going to be consumed here. This would result into a neutral solution pH = 7

What is the slope of the line tangent to the polar curve r=3θ at the point where θ=π2 ?
The slope of the line tangent to the polar curve r = 3θ at the point where θ = π/2 is; Undefined
What is the slope of the line tangent?
By converting into parametric equations, we have;
x(θ) = r(θ) cos θ = cos 3θ cos θ
y(θ) = r(θ) sin θ = cos 3θ sin θ
By product rule;
x'(θ) = -sin 3θ cos θ - cos 3θ sin θ
x'(π/2) = -sin 3(π/2) cos (π/2) - cos 3(π/2) sin (π/2)
x'(π/2) = 0
y'(θ) = -sin 3θ sin θ + cos 3θ cos θ
y'(π/2) = -sin 3(π/2) sin (π/2) + cos 3(π/2) cos (π/2)
y'(π/2) = 1
The slope m of the curve is gotten from;
m = y'(π/2)/x'(π/2)
m = 1/0
Thus the slope is undefined
