What is dilation?

In Geometry, dilation can be defined as a type of transformation which typically changes the size of a geometric object, but not its shape.

Additionally, a geometric figure that is translated downward simply means subtracting a digit from the value on the y-coordinate of the pre-image or parent function.

By critically observing the graph of the function shown above, we can logically deduce that it is a cube root function that has been vertically shifted by a scale factor of 2 units and then translated downward by 4 units. Therefore, this can be modeled by this equation as follows;

f(x) = 2∛x - 4.

The output is seven less than the input

Answers

The function rule describes the connection between the input or domain and the output or range and we know that the required function rule is x=y-7.

What do we mean by function rule?

The relationship between the input or domain and the output or range is known as the function rule.

If and only if there is a single value in the range for each domain value, then a relation is a function.

Consequently, the expression f (x) = 3 x + 1 can be used to represent the function rule y = 3 x + 1.

Function notation is the name for this method of expressing a function rule.

We can read the function notation above as A function exists that is "expressed in terms of the variable" in such a way that it equals 3 x + 1 or of equals 3 x + 1.

So, Y is the result, and x is the input.

According to the provided information, the output is 7 less than the input.

Since the output is y and the input is x, y is therefore 7 less than x.

Since y is 7 less than x, you may express that as an equation, giving you x = y -7.

Use the vertex (h,k) and a point on the graph (x,y) to find the general form of the equation of the quadratic function.
(h,k)=(−3,3) , (x,y)=(2,10)

Answers

Answer:

  y = 7/25x² +42/25x +5 13/25

Step-by-step explanation:

You want the general form of the equation for the quadratic function that has (-3, 3) as its vertex and (2, 10) as a point on the graph.

Vertex form

The vertex form equation is ...

  y = a(x -h)² +k

where (h, k) is the vertex and 'a' is a vertical scale factor.

For the given vertex, this becomes ...

  y = a(x +3)² +3

We want to find 'a' such that the point (x, y) =(2, 10) satisfies the equation:

  10 = a(2 +3)² +3

  7/25 = a . . . . . . subtract 3, divide by 25

General form

The expanded equation is ...

  y = 7/25(x +3)² +3 = 7/25(x² +6x +9) +3

  y = 7/25x² +42/25x +5 13/25

General form of the equation of the quadratic function:

y = (7/25)x² + (42/25)x + 138/25

What is quadratic function?

A quadratic function is a polynomial function with one or more variables in which the highest exponent of the variable is two.


Given

vertex (h,k) = (−3,3)

Point (x,y) = (2,10)

Standard Form Equation for a Parabola:

a(x-h)² = y-k

for vertex (h,k)

(h,k) = (−3,3)

a(x - -3)² = y - 3

a(x + 3)² = y - 3               ______(1)

(x,y)=(2,10)

a(2+3)² = 10 - 3

25a = 7

a = 7/25

Substituting value of a in equation 1

(7/25)(x+3)² = y - 3

(7/25) (x² + 9 + 6x)  = y - 3

7x² + 63 + 42x = 25y - 75

7x² + 63 + 75 + 42x = 25y

7x² + 42x + 138 = 25y

⇒ y = (7/25)x² + (42/25)x + 138/25

Hence, y = (7/25)x² + (42/25)x + 138/25 is the general form of the equation of the quadratic function.

Cargo is tied with rope on the roof of a 45-foot tall car. The car travels down a road at 40 mi/h and hits a concrete barrier and the rope snaps, allowing the cargo to propel forward. Find the time it
takes for the cargo to hit the groupd and the horizontal distance the cargo travels. Let y represent height in feet, let x represent horizontal distance in feet, and let rrepresent time in seconds.
Equation 1:7-1611²+ 45
Equation 27-0047x²+45

Answers

Answer:5.29 seconds to hit ground 30.86 feet in air

Step-by-step explanation:

The first equation, y = 7.16t^2 - 40t + 45, represents the vertical position of the cargo as a function of time.

The second equation, y = -0.047x^2 + 45, represents the height of the cargo as a function of horizontal distance traveled.

To find the time it takes for the cargo to hit the ground, we need to find when y = 0 in the first equation.

Setting y = 0, we have:

0 = 7.16t^2 - 40t + 45

Solving for t, we can use the quadratic formula:

t = (-b ± √(b^2 - 4ac)) / (2a)

where a = 7.16, b = -40, and c = 45.

t = (40 ± √(40^2 - 4 * 7.16 * 45)) / (2 * 7.16)

t = (40 ± √(1600 - 322.2)) / (2 * 7.16)

t = (40 ± √1277.8) / (2 * 7.16)

t = (40 ± 35.62) / 14.32

t = (75.62 / 14.32, 4.38 / 14.32)

Since t must be positive, t = (75.62 / 14.32) = 5.29 s

Now that we have the time it takes for the cargo to hit the ground, we can use that time in the second equation to find the horizontal distance the cargo traveled.

x = √((45 - 0) / -0.047)

x = √(45 / -0.047)

x = √(45 * -21.28) = √(957) = 30.86 ft

Leonel has a soccer game on a rectangular field, which is 15 meters wide and 40 meters long. Marcos wants to know what is the perimeter of the court?​​

Answers

The perimeter of a rectangular field is the sum of all its sides. To find the perimeter of a rectangle you have to add twice the width to twice the length.
The perimeter of the rectangular field would be: 2 * 15 + 2 * 40 = 30 + 80 = 110 meters
Answer:

[tex]\therefore[/tex] Leonel will play on his soccer field with a perimeter of 110 m.

Step by step explanation:

Data to then substitute into the equation:

Let "a" = 15 meters wideLet "b" = 40 meters long

Before starting to solve, I will show you the formula for the perimeter of the rectangle:

[tex]\bold{ \: P= 2(a) + 2(b)}[/tex]

We substitute equation:

[tex]\bf \: P = 2(15) + 2(40)[/tex]

We multiply:

[tex]\bf \: P= 15 * 2 = 30[/tex]

[tex]\bf \: P= 40 * 2 = 80[/tex]

We add both resultants to obtain the perimeter:

[tex]\bf \: P= 80 + 30[/tex]

[tex]\large\boxed{ \bf \:P = 110 \: m}[/tex]

Rpt: Leonel will play on his soccer field with a perimeter of 110 m.

The equation that has infinite number of solutions is A: 5x = 4x + 1.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

When certain requirements are met, an equation can have an unlimited number of solutions. In the case of coinciding lines with the same y-intercept, the number of solutions to the equation system is unlimited. The two lines are actually in the same line if they share the same slope and y-intercept.

The first equation is 5x = 4x + 1.

Solve the equation -

5x - 4x = 1

x = 1

The x value is obtained as 1 which means the line is made parallel to the y-axis at point x = 1.

Therefore, this line has infinite number of solutions.

The second equation is 2 - 2x = -2(x - 1).

Solve the equation -

2 - 2x = -2x + 1

-2x + 2x = 1 - 2

0 = -1

This equation doesn't exist.

Therefore, there are no solutions for the equation.

The third equation is 2x + 7 = 2x - 7.

Solve the equation -

2x - 2x = -7 + 7

0 = 0

This equation doesn't exist.

Therefore, there are no solutions for the equation.

The fourth equation is 5x + 4 = 5(x + 4).

Solve the equation -

5x + 4 = 5x + 4

5x - 5x = 4 - 4

0 = 0

This equation doesn't exist.

Therefore, there are no solutions for the equation.

You deposit $10000 into a standard simple interest savings account. You deposit $12000 into a higher yield account whose interest rate is triple the basic account. In one year, you make $460 in interest. What were the interest rates for each account?

ANSWER THESE⬇️⬇️
Focus on the question at the end of the situation. What is unknown about the situation? Define variables to represent these unknowns.

What are the TWO situations that are being described in the problem? Write an equation that represents each.

Answers

The interest rate for the basic account is 10% and the interest rate for the higher yield account is 30%.

What were the interest rates for each account?

Let the basic account interest rate be r, then the higher yield account interest rate is 3r.

The interest earned in the basic account is r * $10000 = $1000r.The interest earned in the higher yield account is 3r * $12000 = $3600r.

The total interest earned ($460) is

$1000r + $3600r = $460

$460 = $4600r

Dividing both sides by $4600:

r = 0.1

This gives

r - 10%

So, the interest rate for the basic account is 10%

Suppose we are using a Riemann sum with right rectangles to approximate ∫ 05 f(x) dx for some function f(x). Which of the following sums would you expect to give the best approximation? There is not enough information to tell. O a rectangle approximation with Δx=20
O a rectangle approximation with Δx=2
O a rectangle approximation with Δx=0.02
O a rectangle approximation with Δx=0.2

Answers

The approximation is: A1 = f(0) * 2, A2 = f(2) * 2, A3 = f(4) * 2, A4 = f(6) * 2.

To calculate the approximate integral using a Riemann sum with right rectangles, we need to calculate the area of each rectangle and then add them all together. The area of each rectangle is given by the formula A = f(x) * Δx, where f(x) is the value of the function at a given x and Δx is the width of the rectangle.

For a rectangle approximation with Δx=20:

Calculate the x-coordinates of the right endpoints of the rectangles:

x1 = 0, x2 = 20, x3 = 40, x4 = 60.

Calculate the values of f(x) at each x-coordinate:

f(x1) = f(0), f(x2) = f(20), f(x3) = f(40), f(x4) = f(60).

Calculate the area of each rectangle using the formula A = f(x) * Δx, where

Δx = 20: A1 = f(0) * 20, A2 = f(20) * 20, A3 = f(40) * 20, A4 = f(60) * 20.

Add up the areas of all the rectangles to get the approximate integral:

∫0 5 f(x) dx ≈ A1 + A2 + A3 + A4.

For a rectangle approximation with Δx=2:

Calculate the x-coordinates of the right endpoints of the rectangles:

x1 = 0, x2 = 2, x3 = 4, x4 = 6.

Calculate the values of f(x) at each x-coordinate:

f(x1) = f(0), f(x2) = f(2), f(x3) = f(4), f(x4) = f(6).

Calculate the area of each rectangle using the formula A = f(x) * Δx, where

Δx = 2: A1 = f(0) * 2, A2 = f(2) * 2, A3 = f(4) * 2, A4 = f(6) * 2.

Add up the areas of all the rectangles to get the approximate integral:

∫0 5 f(x) dx ≈ A1 + A2 + A3 + A4, where:

A1 = f(0) * 2, A2 = f(2) * 2, A3 = f(4) * 2, A4 = f(6) * 2.
