A marble started with 0.0018 J of Potential Energy and at some point later it has only 0.0011 J of Potential Energy. How much Kinetic Energy does the marble have?
Answers
Answer:
the Kinetic Energy of the marble at the later point is 0.0007 J
Step-by-step explanation:
Given;
initial potential energy of the marble, P.E₁ = 0.0018 J
final potential energy of the marble, P.E₂ = 0.0011 J
At the initial starting point, the total mechanical energy is;
M.E = K.E + P.E
at the initial starting point, velocity = 0
M.E = 0 + P.E
M.E = P.E = 0.0018 J
At some point later, the total mechanical energy is;
M.E = P.E + K.E
0.0018 J = 0.0011 J + K.E
0.0018 J - 0.0011 J = K.E
0.0007 J = K.E
Therefore, the Kinetic Energy of the marble at the later point is 0.0007 J

The scale factor of two similar hexagons is 5:12. The smaller hexagon has an area of 24 square units. What is the area of the larger hexagon?
Answers
Answer: [tex]138.24\ \text{square units}[/tex]
Step-by-step explanation:
Given
The scale factor of two similar hexagons is 5:12.
The smaller hexagon has an area of 24 square units
we know, the ratio of two similar figures is equal to the square of the scale factor.
Suppose the area of the larger hexagon is A
[tex]\therefore \dfrac{24}{A}=\left[\dfrac{5}{12}\right]^2\\\\\Rightarrow A=\left[\dfrac{12}{5}\right]^2\times 24\\\\\Rightarrow A=138.24\ \text{square units}[/tex]

Answer:
a. d(x) = x
b. yes
Step-by-step explanation:
a. since c(x) = [tex]x^{2}[/tex] + 1
c(d(x)) = (d(x))^2 + 1 (replace x with d(x))
that means d(x) has to be x for c(d(x)) to equal [tex]x^{2}[/tex] + 1
b. for example if you use 2 as x, c(d(x)) will equal 5 since d(x) = 2 and [tex]2^{2}[/tex] + 1 = 5
d(c(x)) will also equal 5 because c(x) = [tex]2^{2}[/tex] + 1 = 5 and d(c(x)) = c(x) = 5

Julie was given a new map of New Hampshire to calculate some distances. The scale is 1 inch = 50 miles. How far is Conway from Littleton?
Answers
Answer:
Conway is 312.50 miles from Littleton
Step-by-step explanation:
Given
[tex]Scale: 1\ in = 50\ mi[/tex]
See attachment
Required
Distance between Conway and Littleton
The scale distance between Conway and Littleton is 6.25 inches.
So, the actual distance is calculated as:
[tex]1\ in = 50\ mi[/tex]
Multiply both sides by 6.25
[tex]6.25 * 1\ in = 50\ mi * 6.25[/tex]
[tex]6.25\ in = 312.50\ mi[/tex]
Hence, Conway is 312.50 miles from Littleton

= 1,000 * 30%
= $300
The store is selling 30% off, this means that they are reducing the price by 30%:

A company finds that if it charges x dollars for a cell phone, it can expect to sell 1,000−2x phones. The company uses the function r defined by r(x)=x⋅(1,000−2x) to model the expected revenue, in dollars, from selling cell phones at x dollars each. At what price should the company sell their phones to get the maximum revenue?
Answers
Answer:
$500 will give the company the maximum revenue
Step-by-step explanation:
Given
[tex]r(x) = x (1000 - 2x)[/tex]
Required
Price to generate maximum revenue
We have:
[tex]r(x) = x (1000 - 2x)[/tex]
Open bracket
[tex]r(x) = 1000x - 2x^2[/tex]
Rewrite as:
[tex]r(x) = - 2x^2 + 1000x[/tex]
The maximum value of x is calculated using:
[tex]x = -\frac{b}{2a}[/tex]
Where:
[tex]f(x) = ax^2 + bx + c[/tex]
So:
[tex]a \to -2[/tex]
[tex]b = 1000[/tex]
[tex]c = 0[/tex]
[tex]x = -\frac{b}{2a}[/tex]
[tex]x = -\frac{1000}{-2}[/tex]
[tex]x = \frac{1000}{2}[/tex]
[tex]x = 500[/tex]
