Answer: Nicole Kicked the ball Father by  22 feet than Tyrell.

The force of gravity caused the soccer ball to return to the girl.

By means of gravity, a planet or other body pulls items toward its center.

It is, in ideal circumstances, abiding by Newton's third law of gravitation and force.

Each action has a corresponding and opposing reaction.

So, when a boy kicks a ball and it comes back, that signifies he is abiding by the law.

Nicole kicked the ball 57 feet

Tyrel kicked the ball 35 feet

Nicole  Kicked the ball Father by = 22feet

This is gotten by subtracting the distance Nicole kicked from that of Tyrel

=57 feet - 35feet = 22feet

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.

Answer:

a = √63

Step-by-step explanation:

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.

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

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.

Answer:

The distance between two points in the coordinate plane can be found using the distance formula, which is:

distance = √((x2 - x1)^2 + (y2 - y1)^2)

In this case, the two points are (3,2) and (6,0), so we can plug in the values to get:

distance = √((6 - 3)^2 + (0 - 2)^2)

distance = √((3)^2 + (-2)^2)

distance = √(9 + 4)

distance = √13

So the distance between the two points (3,2) and (6,0) is approximately 3.61 units.

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.

Answer: 6

Step-by-step explanation:

Let's start by rewriting the expression. Essentially, this is asking us for 3 * (times) √4 (square root of four).

Now, we can solve √4. Since we know that 2*2 = 4. That means that 2² = 4, so essentially, if we take the square root of 4, we will get back to two.

Now, we can solve the rest: 3 * 2 = 6

In the end, 3√4 = 6. Hope this helps!

The change between outputs found by dividing one output by its previous output is called output elasticity.

What is output elasticity?

Output elasticity is defined as the division of change in output by change in input which is the previous output.

General, elasticity is a concept that is used to measure the change in the aggregate quantity demanded of a good or service in relation to price movements of that good or service.

A product is considered to be elastic if the quantity demand of the product changes more than proportionally when its price increases or decreases.

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

A = 60 in².

     S = (a+b+c)/2

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

The sides of the triangle KLM are:

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:

A = 60 in².

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)

Step-by-step explanation:

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

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
