a grain of salt has an approximate length of 9.8x10 to the -4 feet. The approximate height of Mt. Everest is 2.9035x10 to the power of 4 feet. Calculate the approximate number of grains of salt it would take to reach the height of Mt. Everest..

Answers

Answer 1

The approximate number of grains of salt it would take to reach the height of Mt. Everest is; 0.2963 * 10⁸

How to divide exponents?

We are given;

Approximate length of a grain of salt = 9.8 * 10⁻⁴ ft

Approximate height of Mt. Everest = 2.9035 * 10⁴ ft

Now, we want to know the approximate number of grains of salt it would take to reach the height of Mt. Everest. To get this it means we have to divide the Approximate height of Mt. Everest by the Approximate length of a grain of salt.

According to Laws of exponents, we know that;

x³/x² = x^(3 - 2) = x¹

Thus;

Approximate number of grains of salt it would take to reach the height of Mt. Everest = (2.9035 * 10⁴)/(9.8 * 10⁻⁴) = (2.9035/9.8) * (10⁴⁻⁽⁻⁴⁾) = 0.2963 * 10⁸

Step-by-step explanation

[tex]-7(x-2)-28-14[/tex]

To solve this, we must first solve what is inside the parenthesis by the distributive property. We will multiply -7 by x and -2.

[tex]-7(x)=-7x\\-7(-2)=14[/tex]

So then we have:

[tex]-7x+14-28-14[/tex]

7x does not have any like terms, so we just combine 14, -28, and -14.

What is a Circular arc?A section of curvature or a circle is referred to as an arc in mathematics. The chord of the circle is the line that forms the connection between the arc's ends. A semicircular is exactly half the length of the circle.If the two points are not exactly opposite one another, the major arc will subtend an angle larger than radians at the circle's center whereas the minor arc will subtend an angle less than radians (180 degrees).Plotting two lines from the arc's ends to the circle's center, measuring the angle at which the two lines intersect, and solving for L by cross-multiplying the resulting statement are useful methods for calculating an arc's length.

In Mathematics, the graph of any proportional relationship is characterized by a straight line with the points passing through the origin (0, 0) because as the values on the x-axis (x-coordinate) increases or decreases, the values on the y-axis (y-coordinate) increases or decreases simultaneously.

Vector:

Vector means the objects which have both, magnitude and direction. Magnitude defines the size of the vector. It is represented by a line with an arrow, where the length of the line is the magnitude of the vector and the arrow shows the direction.

Given,

Vector v = <3, 1>.

Here we need to find the value of u through the given graph and we have to perform the addition operation in order to find the component form of the resulting vector.

Here we have the value of vector v = <3,1>

While observing the graph we have identified as the value of vector u is,

x value = 2

y value = -5

So, the component from of vector u = <2, -5>

Now the addition of u + v is equal to,

Suppose PQ has one endpoint at P (4, 6) and a midpoint coordinate of (-5, 9).
The coordinate for Point Q is

Answers

Answer:

(-14,12)

Step-by-step explanation:

Way 1: (little more complicated)
we know two things,
The two halves of the line have the same slope, and that the length from the endpoint to the midpoint is equal to the length from the midpoint to the other end point.
The slope is equal to: (6-9)/(4-(-5)) = -3/9 = -1/3
The length is equal to (using the Pythagorean theorem):
height = delta y = 9 - 6 = 3
length = delta x = 4 - (-5) = 9
3^2+9^2=hypotenuse^2
9+81 = h^2
h = sqrt(90)
So, the let's say point Q has the coordinate (a, b).
The formula of the slope would give us (b-9)/(a-(-5)) = -1/3
The formula of the hypotenuse would give us (b-9)^2+(a-(-5))^2 = 90
solving the system of equations, we would get that a = -14 and b = 12, so the point is (-14,12)
Make sure to be careful, however, because you will get two points with this system of equations. Only one works
Way 2:
since from point P to the midpoint we went to the left by 9 and up by 3, from the midpoint to point Q, we would go left by 9, and up by 3.
from the midpoint (-5,9), go left by 9, so x decreases by 9 to get (-14, 9).
go up by 3, so y increases by 3 to get (-14,12). This agrees with our other answer

The volume of the figure shown in the reference attachment, provided hereby with the question statement will be 6786 ft³.

As per the question statement and the reference attachment, we are provided with a figure and its dimensions.

We are required to calculate the volume of the concerned figure using the dimensional values provided.

To solve this question, we need to calculate the volumes of the bottom cuboidal part, and the top pyramidal part separately, and then add these volumes, to obtain our final desired answer.

Given, the dimensions of the bottom cuboidal part is (21ft by 18ft by 13ft).

We know that, volume of a cuboid = (length * breadth * height).

Therefore, volume of our concerned bottom cuboidal part

= (21 * 18 * 13) ft³

= 4914 ft³.

Also given, the dimensions of the top pyramidal part are as follows,

Base of the triangle  = 18 ft,

Altitude of the triangle  = 16 ft,

and length of the pyramid = 13 ft.

Therefore, Volume of the concerned pyramid

= [(1/2) * base * altitude * length]

= [(1/2) * 18 * 16 * 13] ft³

= (9 * 16 * 13) ft³

= 1872 ft³.

Therefore, Total volume of the concerned figure shown in the reference  attachment, provided hereby with the question statement will be

(4914 + 1872) ft³ = 6786 ft³

The velocity of the cart b is found as 20/23 ft/s over the pulley.

What is defined as the rate of change?The momentum of a variable is represented by the rate of change, which is used to mathematically define the percentage change in value over such a defined period of time.

For the given data in the question.

q's velocity is 2 feet per second.

Rope length is 39 feet.

Assume x is the distance between A and Q. (refer the image).

Assume y is the distance between Q and B. (refer the image).

As a result of the image,

x² + 12² = L²

Now, with respect to time t, differentiate the above equation.

2x(dx/dt) + 0 = 2L.(dL/dt)

For x = 5 ft and L = 13 ft

dL/dt = (5×2)/13 = 10/13

In the case of B,

y² + 12² = (39 - L)² ; from diagram.

Differentiating now,

2y(dy/dt) + 0 = -2(39 - L).(dL/dt)

At x = 5 ft and y = 23 ft.

dy/dy = -20/23

(A negative sign indicates the opposite direction)

Thus, the velocity of cart b is found as 20/23 ft/s.

Write the equation of the Line in slope intercept form?

We are told that a line goes through the points; (12, 13) and (-8, 8)

1) The slope is gotten from the formula;

m = (y2 - y1)/(x2 - x1)

m = (8 - 13)/(-8 - 20)

m = -5/-28

m = 5/28

The equation of the hyperbola is -(1/16) (x +4)² + (1/4) (y +2)² = 1

What is Hyperbola?

A hyperbola is a particular kind of smooth curve that lies in a plane and is classified by its geometric characteristics or by equations for which it is the solution set. A hyperbola is made up of two mirror images of one another that resemble two infinite bows. These two sections are known as connected components or branches.

The intersection of the two asymptotes is where the hyperbola's center is located. This is the key idea (-4,-2)

We have y orientation because the vertex at (-4,0) is above this location. The equation will take the form as a result.

-a (x + 4)

2 + b (y + 2)

In the case of certain a and b, 2 Equals 1.

Inputting (-4,0) reveals that b = 1/4.

Finally, requiring that y = x/2 be an asymptote reveals that a = 1/16.

-(1/16) (x +4)² + (1/4) (y +2)² = 1
