A 1.5 kg pendulum swings from point A of height yA = 0.04m to point B of height yB = 0.12m. The heights are relative to the lowest height. What is the change in gravitational potential energy from A to B?

Answers

Answer 1

Answer:

The change in gravitational potential energy from point A to point B can be calculated using the formula:

ΔU = mgh

Where:

m = mass of the pendulum = 1.5 kg

g = acceleration due to gravity = 9.8 m/s^2

h = change in height = yB - yA = 0.12 m - 0.04 m = 0.08 m

So, the change in gravitational potential energy from A to B is:

ΔU = (1.5 kg)(9.8 m/s^2)(0.08 m) = 1.176 J

So, the change in gravitational potential energy from A to B is 1.176 Joules.

The rule for the graph changes form of the function is A)The graph is reflected across the x-axis.

What is function?

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). Function is a relation that connects members of one set in a certain way to those of another set. Formally speaking, a function from to is an object such that each is specifically linked to an object. Therefore, a function is a many-to-one (or occasionally, one-to-one) relation.

Here Through moving up c units, the graphs of g can be determined from the graph of f. If we subtract c from f(x), the graph shifts downward. Let   h(x) = f(x)-c Shifting downward c units yields this graph of h from the graph of f.

We know that if the function reflected over x-axis then

g(x) = -f(x)

Here the given function f(x) = [tex]x^2-4[/tex] then reflection over x-axis then

=> g(x) = -f(x)

=> g(x) =-( [tex]x^2-4[/tex])

=> g(x) = [tex]-x^2+4[/tex]

You can hire someone without experience for $13 per hour or someone with experience for $19 per hour. You believe the
experienced person increases the sales per customer by $3. Each person handles about 12 customers per hour. Should you hire the
experienced person?
a) Yes
b) No

Answers

Answer:

a) Yes

The experienced person costs more per hour, but also increases sales per customer. To determine if it is more cost-effective to hire the experienced person, you would need to calculate the net gain or loss from hiring them.

You can do this by multiplying the increase in sales per customer by the number of customers per hour, and comparing that to the difference in hourly wages.

(12 customers/hour * $3/customer) - ($19/hour - $13/hour) = $36/hour - $6/hour = $30/hour

Since the net gain is positive, it is more cost-effective to hire the experienced person.

15. Rahj owns a hardware store. For every increase of 10¢ in the price A of a package of batteries, he estimates that sales decrease by 10 packages per day. The store normally sells 700 packages of batteries per day, at $5.00 per package. a) Determine an equation for the revenue, y, when x packages of batteries are sold. b) What is the maximum daily revenue that Rahj can expect from battery sales? How many packages of batteries are sold when the revenue is at a maximum? also,how to get the zeros and the equation​

Answers

Answer:

a) To determine an equation for the revenue, y, when x packages of batteries are sold, we need to know the price of each package of batteries.

Since the price of a package of batteries is $5.00, the revenue, y, when x packages of batteries are sold is given by y = 5x, where x is the number of packages of batteries sold and y is the revenue in dollars.

b) To find the maximum daily revenue that Rahj can expect from battery sales, we need to find the value of x that maximizes y = 5x.

Given that for every increase of 10¢ in the price A of a package of batteries, sales decrease by 10 packages per day. And the store normally sells 700 packages of batteries per day, at $5.00 per package.

It means that the store will sell a maximum number of batteries when the price is at $5.00

And the maximum daily revenue will be $5 * 700 = $3500.

So the maximum daily revenue that Rahj can expect from battery sales is $3500. And the number of packages of batteries sold when the revenue is at a maximum is 700.

The equation is y = 5x, where x is the number of packages of batteries sold and y is the revenue in dollars.

The zeroes of the equation are the points at which the function crosses the x and y-axis.

The x-intercept is the point at which the function crosses the x-axis. It happens when y = 0. So the x-intercept of this equation is (0,0)

The y-intercept is the point at which the function crosses the y-axis. It happens when x = 0. So the y-intercept of this equation is (0,0)

4x-3 =3x + y. 3x+y =2y+5x-12
simultaneous equation
pls help​

Answers

Answer: To solve these simultaneous equations, we can substitute one equation into the other.

4x-3 = 3x + y.

3x+y =2y+5x-12

If we substitute the first equation into the second equation, we get:

3(4x-3) + y = 2y+5x-12

12x -9 + y = 2y+5x-12

Now we can solve the system of equations by isolating one of the variables and then substituting it back in one of the equations.

12x - 9 + y = 2y + 5x - 12

y = -9 + 2y + 5x -12

y = 2y + 5x -21

y - 2y = 5x -21 -9

-y = 5x -30

y = -5x + 30

Now we can substitute the value of y back into one of the original equations, we have:

4x-3 = 3x + (-5x + 30)

4x-3 = -2x + 30

4x-3+2x = 30

6x -3 = 30

6x = 33

x = 5.5

Now we can substitute the value of x back into one of the original equations to find the value of y:

4x -3 = 3x + y

4(5.5) -3 = 3(5.5) + y

22 - 3 = 16.5 + y

19 = 16.5 + y

y = 2.5

So the solution to the system of equations is x = 5.5 and y = 2.5.

Answers

The diameter of the base of the cylinder is 5.2 cm and the height of the cylinder is 7.1 cm.

To find the volume of the cylinder, we can use the formula:

V = πr^2h

where V is the volume, r is the radius, and h is the height.

To find the radius, we divide the diameter by 2:

r = 5.2 cm / 2 = 2.6 cm

Now we can plug in the values for r and h into the formula:

V = π(2.6 cm)^2(7.1 cm) = π(6.76 cm^2)(7.1 cm) = 47.9 cm^3

So the volume of the cylinder is 47.9 cubic centimeters.

Solve the system by substitution.

O 6x + 5y< 120
5x + 6y> 120
O6x + 5y 120
5x + 6y< 120

Answers

Answer:

The inequality that describes the situation is 5x + 6y < 120

Step-by-step explanation:

This inequality states that the total cost of purchasing x hammers and y wrenches must be less than $120. Each hammer costs $5 and each wrench costs $6, so the total cost is represented by the expression 5x + 6y.

The inequality states that 5x + 6y < 120 which means for any number of hammers and wrenches she buys it should be less than 120.

The other options:

6x + 5y < 120: the coefficient of x is 6 instead of 5 and that of y is 5 instead of 6.

5x + 6y > 120: the inequality is greater than instead of less than, which means that the total cost should be greater than $120 which is not the case.

6x + 5y ≥ 120 : the inequality is greater than or equal to instead of less than, which means that the total cost should be greater than or equal to $120 which is not the case.

Step-by-step explanation:

18 is the diameter , 9 is the radius , what is the area

Answers

Answer: The area of the circle with a radius of 9 is approximately 253.94 square units.

Step-by-step explanation:

The area of a circle is given by the formula A = πr^2, where A is the area, r is the radius, and π is approximately 3.14.

Given that the radius of the circle is 9, we can substitute this value into the formula to find the area:

A = πr^2 = π(9)^2 = 3.14 * 81 = 253.94

So the area of the circle with a radius of 9 is approximately 253.94 square units.

Note that the diameter of the circle is 18, which is twice the radius. If you knew the diameter you could also use the formula A = (π/4)*D^2 to calculate the area, where D is the diameter.

the answer rounded is 254

The area of the triangle KLM is found using Heron's formula as:

A = 60 in².

Explain the Heron's formula.The semi-perimeter of such a triangle, wherein area needs to be calculated, is represented by the letter s in Heron's formula. The total of the triangle's three sides, divided by two, is the semi-perimeter.

     S = (a+b+c)/2

     where a, b, and c are the triangle's three sides.

The sides of the triangle KLM are:

Let KL : a = 13 in.Let LM : b = 13 in.Let KM : c = 10 in.

Then,

Semi perimeter s = a + b + c / 2

s = (13 + 13 + 10)/ 2

s = 18 in

Thus,

s - a : 18 - 13 = 5

s -b : 18 - 13 = 5

s - c : 18 - 10 = 8

By Heron's formula;

area of triangle KLM = √(s - a)(s -b)(s - c)

A = √18*5*5*8

A = 60

Thus, the area of triangle KLM is found using Heron's formula as:

f(x) and g(x) are inverses using composition

How to use composition to prove that f(x) and g(x) are inverses?

A function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

To confirm the inverse relationship using composition.

For valid inverse f(g(x)) must be equal to g(f(x))

f(x) = ∛(x) + 13; g(x) = (x - 13)³:

f(g(x)) = f((x - 13)³)

f(g(x)) = ∛((x - 13)³) + 13

f(g(x)) = x - 13 + 13

f(g(x)) = x

g(f(x)) = g(∛(x) + 13)

g(f(x)) =  (∛(x) + 13 - 13)³

g(f(x)) =  (∛(x))³
g(f(x)) =  x

Since f(g(x)) = g(f(x)) then f(x) and g(x) are inverse

f(x) = x³ + 1; g(x) = ∛(x - 1):

f(x) = x³ + 1; g(x) = ∛(x - 1)

f(g(x)) = f(∛(x - 1))

f(g(x)) =  (∛(x - 1))³ + 1

f(g(x)) =  x - 1 + 1

f(g(x)) =  x

g(f(x)) = g(x³ + 1)

g(f(x)) = ∛((x³ + 1) - 1)

g(f(x)) = ∛(x³)

g(f(x)) = x

Since f(g(x)) = g(f(x)) then f(x) and g(x) are inverse

Answers

Answer:

a = √63

Step-by-step explanation:

Pre-Solving

We are given a right triangle (notice the right angle).

We know that the hypotenuse (the side opposite of the right angle) is 12.

We also know that one leg (a side that makes up the right angle) is 9, and that the other one is a.

We want to find what a is.

Solving

We can use the Pythagorean Theorem to help us find a.

The Pythagorean Theorem says a² + b² = c², where a and b are the legs and c is the hypotenuse.

Since we already know the values of the legs and hypotenuse, we can substitute these values in the theorem, but let's first label the values of everything to avoid confusion / mistakes.

a = a

b = 9

c = 12

Now, plug into the formula.

a² + 9² = 12²

Simplify:

a² + 81 = 144

Subtract 81 from both sides

a² = 63

Square root both sides to get the value of a.

a = √63
