Why do we not feel Earth rotation and revolution?
Earth's rotation and revolution are both very slow motions, so slow that we don't feel them. The rate of Earth's rotation is about 1,000 miles per hour, and the speed of its revolution is about 67,000 miles per hour, but both of those speeds are so slow that we don't feel any movement or acceleration.

Answer:
5 + 2q = 15
Step-by-step explanation:
The perimeter is 4 + 2 + q + (q - 1) = 15.
Add 4 + 2 then subtract the sum from both sides.
q + (q - 1) = 9
This can be simplified further by adding the "q" variables together.
2q - 1 = 9
Add 1 to both sides.
2q = 10
Divide both sides by 2 to isolate q.
q = 5
Given that $k$ is a positive integer less than 6, how many values can $k$ take on such that $3x \equiv k \pmod{6}$ has no solutions in $x$
Supposing the value of x to be an integer, the values of k that donot
satisfy the given equation 3x = k mod 6 are 1,2,4,5.
What is an integer?An integer, which can comprise both positive and negative integers, including zero, is a number without a decimal or fractional portion.
What is the difference between integers and whole numbers?Integers are a set of numbers that include both positive and negative numbers, as well as zero. Whole numbers, on the other hand, only include the set of non-negative numbers starting from 0 (i.e., 0, 1, 2, 3, 4, ...). In other words, whole numbers are a subset of integers.
If 3x = k mod 6 has no solutions in x, then k must not be divisible by 3. The positive integers less than 6 that are not divisible by 3 are 1, 2, 4, and 5. Therefore, k can take on 4 values: 1, 2, 4, and 5.

Using the Pythagoras Theorem the third side c of the right-angled triangle is obtained as 6.5 units.
What is Pythagoras Theorem?
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side.
The data given is -
Assume a, b and c are sides of right-angled triangle.
Then, two adjacent sides of right-angled triangle are -
a^2=29.25 squared units
b^2=13 squared units
The unknown side c is taken to be x.
Find the length of c using Pythagoras Theorem -
c^2=a^2+b^2
where, c is the hypotenuse, a is the perpendicular and b is the base.
Plugging the values in the equation -
x^2=29.25+13
x=√(29.25+13)

A chord of a circle is perpendicular to a radius at the midpoint of the radius. The ratio of the area of the larger of the two regions into which the chord divides the circle to the smaller can be expressed in the form \frac{a\pi+b\sqrt{c}}{d\pi-e\sqrt{f}}, where a, b, c, d, e, and f are positive integers, a and e are relatively prime, and neither c nor f is divisible by the square of any prime. Find the remainder when the product abcdef is divided by 1000.
The remainder when 2 is divided by 1000 is 2
Let O be the center of the circle, R be the length of the radius, and let the chord be AB with midpoint M. Let x be the distance from O to M, then the length of the radius OM is R/2 and the length of the chord AB is 2x.
Since the chord is perpendicular to the radius at the midpoint, we know that the radius bisects the chord. Therefore, the two segments MO and MB are congruent and have length x.
The area of the larger region is the area of the sector OMB, which is (1/4) of the area of the circle. The area of the smaller region is the area of the triangle OMA, which is (1/2) of the area of the sector OMA.
The ratio of the larger region to the smaller region is (1/4) : (1/2) = 2 : 1.
So, the area of the larger region is twice the area of the smaller region.
We can see that abcdef = 21111*1 = 2, the remainder when 2 is divided by 1000 is 2. Thus, the answer is \boxed{002}.

janes is 2 mi offshore in a boat and wishes to reach a costal village 6 mi down a straight shoreine from the point nearest ht eboat
Jane should land 1.5 mi down the shoreline and walk the remaining 4.5 mi to the village to minimize her travel time.
Let x = distance travelled along the shore over water.
Then, 6 − x = distance travelled along the shore over land.
Let T = the total time taken to reach the destination.
T = distance/velocity = √(4 + x²)/3 + (6-x)/5 on [0, 6].
Note that T must be non negative and that x = 6 means the destination
is reached solely by rowing and without the benefit of faster land
travel. In actual fact, T is valid over [0, ∞) but [0, 6] is reasonable here.
T' = x/3√(4 + x²) - 1/5 = 5x - 3√(4 + x²) = 0
⇒5x = 3√(4 + x²)
⇒25x² = 9(4 + x²)
⇒16x² = 36
⇒x = ±6/4 = ±1.5
The negative x value is discarded since it does not belong to [0,6].
T(0) = 28/15 = 1.8667
T(1.5) = 1.733
T(6) = 2.1082
Therefore, Jane should land 1.5 mi down the shoreline and walk the

The equation of the line that passes through the points (−8, −10) and (6, 3)in slope-intercept form is y = (13/14) x - 18/7.
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The slope-intercept form of the equation of a line is given by the formula:
y = mx + b
where m is the slope of the line
b is the y- intercept
Given the two points, (−8, −10) and (6, 3), get the slope of the line using the formula:
m = (y₂ - y₁) / (x₂ - x₁)
m = (3 - -10) / (6 - -8)
m = 13 / 14
Using the slope-intercept form, plug in the value of the slope and one point to determine the y-intercept, b.
y = mx+ b
-10 = (13/14)(-8) + b
b = -18/7
Substitute the value of the slope and y-intercept in the slope-intercept form.
y = mx + b
y = (13/14) x - 18/7
Hence, the equation of the line in slope-intercept form is y = (13/14) x - 18/7.

The number of points is simply 5 times this random variable, and E(C*Y) = C*E(Y), where C is a constant and Y is a random variable, according to expected value principles. As a result, E(X) = 5*2 = 10.
What is probability?The field of mathematics concerned with probability is known as probability theory. Although there are various distinct interpretations of probability, probability theory approaches the idea rigorously mathematically by articulating it through a set of axioms. A probability is a number that represents the possibility or chance that a specific event will occur. Probabilities can be stated as proportions ranging from 0 to 1, as well as percentages ranging from 0% to 100%.
Here,
The number of dice that are showing an even number is a binomial random variable with n = 4, and p = 1/2 (because half the faces on the die are even and half are odd).
The expected value of this random variable is n*p = 4*1/2 = 2.
The number of points is simply 5 times this random variable, and by the rules of expected value, E(C*Y) = C*E(Y), where C is a constant and Y is a random variable. Thus E(X) = 5*2 = 10.

What is the solution to the equation 1 h 5 2 h 5?
h = 7 is the solution to the equation 1/ (h - 5) + 2/ (h + 5) = 16 / (h² - 25)
What is an equation?The meaning of such an equations in algebra is just a mathematical expression stating the equality between two mathematical terms. For instance, 6x + 5 = 11 is an equation where 6x + 5 and 11 are two expressions separated by the 'equal' sign.
Identity equations and conditional equations are the two types of equations. For just any value of both the variables, an equality remains true. Only such variables have values that make a condition expression true. Two expressions joined by an equals sign ("=") form an equation.
The equation given that,
1/ (h - 5) + 2/ (h + 5) = 16 / (h² - 25)
The least common multiple of the denominators is:
h² - 25 = (h - 5) (h + 5)
We multiply through with the LCM to obtain:
= [(h - 5) × (h + 5)] × [1 / (h - 5)] + [(h - 5) × (h + 5)] × [2 / (h - 5)]
= 16 / (h² - 25) × [(h - 5) × (h + 5)]
We cancel out common factors to obtain:
= 1 (h + 5) + 2 (h - 5)
= 16
We expand the brackets to obtain
= h + 5 +2h - 10
We group like terms to get:
h + 2h = 16 - 5 + 10
This simplifies to:
3h = 21
We now divide through by 3 to obtain:
h = 7
