A signal from a satellite in space travels to the surface of the Earth at the speed of light. The distance between the satellite and the surface of the Earth is 30,425 kilometers. How long does it take for the signal to reach the surface of the Earth, to the nearest thousandth of a second? (Note: Use 3.0 x 10 meters/second for the speed of light. 1 kilometer = 1,000 meters)​

A Signal From A Satellite In Space Travels To The Surface Of The Earth At The Speed Of Light. The Distance

Answers

Answer 1

Answer:

0.101

Step-by-step explanation:

[tex]speed = \frac{distance}{time} [/tex]

We have speed, and we have distance. So let's rearrange to get time:

[tex]time = \frac{distance}{speed} [/tex]

Let's plug in our numbers (make sure to times distance by 1000 to convert to metres):

[tex]time = \frac{30425000}{3.0 \times {10}^{8} } [/tex]

Which leaves us with:

[tex]time = \frac{1217}{2 ^ {5} \cdot 3 \cdot 5 ^ {3}} \approx 0.101416667[/tex]

A grocery store usually orders 1500
frozen dinners every week. They have
been selling out and have decided they
need to order 2100 each week to keep
up with demand. What is the percent
increase?

Answers

Answer:

40%

Step-by-step explanation:

The concept of percent increase is basically the amount of increase from the original number to the final number in terms of 100 parts of the original. An increase of 5 percent would indicate that, if you split the original value into 100 parts, that value has increased by an additional 5 parts. So if the original value increased by 14 percent, the value would increase by 14 for every 100 units, 28 by every 200 units and so on. To make this even more clear, we will get into an example using the percent increase formula in the next section.

119=7(2e+7)

Answers

Answer:

e=+5

Step-by-step explanation:

119=7(2e+7)

We move all terms to the left:

119-(7(2e+7))=0

We calculate terms in parentheses: -(7(2e+7)), so:

7(2e+7)

We multiply parentheses

14e+49

Back to the equation:

-(14e+49)

We get rid of parentheses

-14e-49+119=0

We add all the numbers together, and all the variables

-14e+70=0

We move all terms containing e to the left, all other terms to the right

-14e=-70

e=-70/-14

e=+5

Step-by-step explanation:

the other answer is right but it seems a bit overly complicated how the result was achieved.

119 = 7(2e + 7)

119 = 14e + 49

70 = 14e

e = 70/14 = 5

that's really it.

The Simpsons rented a trailer that was 8 feet long and 5 feet wide. If they load the trailer with 1-by-1-by-1-foot boxes to a height of 3 feet, how many boxes can be loaded onto the trailer?​

Answers

The total number of boxes that can be loaded onto the trailer is 27.

Here we have to determine the maximum number of boxes.

That can be stored in a locker by the volume of one box.

From the given information volume of the box is Vb and the volume f the locker is Vl.

What is the volume of the box?

[tex]Volume=Length\times width\times height[/tex]

Therefore we get,

[tex]V_b=4\times3\times2\\V_b=24ft^3[/tex]

The volume of the locker is

[tex]V_L=12\times6\times 9\\V_L=684ft^3[/tex]

Therefore the number of the maximum boxes are

[tex]\frac{VL}{V_b} =\frac{648}{24} \\=27[/tex]

Therefore, The total number of boxes can be loaded onto the trailer are 27.

The area will be equal to Area = (28)(21) / 2 = 294 square inches.

What is the area?

To determine the area of a triangle, we calculate one half of the product of the base and the height of the triangle so we need data on its base and its height. We are given the following:

Hypotenuse = 7 + base = 14 + height

Perimeter = 84 inches

The perimeter of the triangle is equal to the sum of the three sides of the triangle which are the height, base and hypotenuse. So,

Perimeter = height + base + hypotenuse = 84

We let x = height and y = base. We calculate area as follows:

84 = x + y + (7 + y)

77 = x + 2y

x = 77 -2y

The Hypotenuse is related to the other sides by the Pythagorean theorem.

Hypotenuse^2 = (x^2 + y^2)

(14 + x)^2 = x^2 + y^2

(14 + (77-2y))^2 = (77-2y)^2 + y^2

(91-2y)^2 = (77-2y)^2 + y^2

Solving for y and x

y = 28

x = 21

Area = (28)(21) / 2 = 294 square inches

A(x)=x(10-x)
When is A(x) at its maximum? Explain
Or show how you know.

Answers

Answer:

A(x) is at its maximum at x = 5, or (5, 25)

Step-by-step explanation:

Putting A(x)=x(10-x) back into its standard form gives A(x) = -x^2 + 10x. The equation to find the x value in vertices in these types of functions is -b / 2a, the letters pertaining to the coefficients. In this case, this graph would have a maximum at -(10)/2(-1), or -10/-2 = 5 --> Thus, when x=5, the downwards facing graph is at its maximum

(Might not be important but another method to solve:)
Take the derivative of the function A(x) = x(10-x) and set it equal to 0 to find the x value of all vertices. In this case, A'(x) = -2x + 10,
-2x + 10 = 0
-2x = -10
x = 5
A(x) is at its maximum at x=5 because it is when A'(x), the derivative, is equal to 0 and thus has a flat slope (or vertex)

Answer:

(5, 25)

Step-by-step explanation:

A(x) is a parabola meaning the max point would be called the vertex

Expand A(x)

[tex]x(10 - x) = 10x - x^{2}\\x^{2} -10x[/tex]

The vertex point is (h, k)

To find h:

[tex]h =- \frac{-b}{2a} \\b = -10\\a = 1\\h = - \frac{-10}{2(1)} \\h = - \frac{-10}{2} \\h = 5[/tex]a and b are from the equation [tex]ax^{2} + bx[/tex]

To find k, plug in h values:

[tex]k = \\f(5) = 5^{2} - 10(5)\\f(5) = 25[/tex]

vertex = (h, k) = (5, 25)
