Answer: 52(4x+8) in simplified form is 208x + 416.
Step-by-step explanation:
To simplify 52(4x+8) we need to first use the distributive property, which states that:
a(b+c) = ab + ac
So, we can rewrite 52(4x+8) as:
52 * 4x + 52 * 8
Now we can just multiply the numbers:
52 * 4x = 208x
52 * 8 = 416
so the expression simplifies to:
208x + 416
So, 52(4x+8) in simplified form is 208x + 416.
Let’s begin with a 30°-60°-90° triangle. A 30°-60°-90° triangle with a hypotenuse of 2 units is shown.
If another right triangle contains a 30° or a 60° angle but is a different size, what can you say about the side lengths of that triangle in terms of the given triangle? Explain your answer.
The side lengths of the new right triangle can be determined by the ratio of the given triangle.
What is triangle?A triangle is a three-sided polygon with three straight sides that are connected at three corners. It is one of the most basic shapes in geometry and is found in many areas of mathematics. Triangles can be classified according to their angles, sides, and size. They can be equilateral, isosceles, or scalene, depending on the size of their angles and sides. Triangles are used in a variety of fields, including architecture, engineering, construction, art, and design.
The side opposite the 30° angle will always be half the length of the hypotenuse, while the side opposite the 60° angle will always be equal to the square root of three times the length of the side opposite the 30° angle. This means that if the hypotenuse of the given triangle is 2, then the side opposite the 30° angle will be 1 and the side opposite the 60° angle will be √3.
Therefore, for any other right triangle containing a 30° or a 60° angle, the side length can be found by multiplying the side length of the given triangle by the same ratio. For example, if the hypotenuse of the new triangle is 6, then the side opposite the 30° angle will be 3 and the side opposite the 60° angle will be 3√3.
In conclusion, for any right triangle containing a 30° or a 60° angle, the side lengths can be determined by multiplying the side lengths of the given triangle by the same ratio.

Answer: $87.99
Step-by-step explanation: ($125.70) x (1 - 0.30)
= $87.99
Answer: $87.99
Step-by-step explanation:
Use Is/Of=%/100
Step 1: Plug in Points
Aardvark=$125.70 is on sale for 30% off
is/125.70=30/100 ---> 125.70(30)/100=$37.71

What is the value of x? round to the nearest tenth, if necessary. Responses x = 4 x, = 4 x = 5 x, = 5 x = 6. 2 x, = 6. 2 x = 9. 4.
The value of x is 6.2 units.
Now by using the Pythagorean theorem
Hypotenuse² = Perpendicular² + Base²
Now in the Δ ABD
As given DB² = DA² + AB²
As given
DB = 13 units
AB = 9 units
Putting values in the above
13² = 9²+ DA²
169 - 81 = DA²
88 = DA²
DA=√88
In ΔABC
AB² = AC² + CB²
(As given AB = 9 units , CB = x)
9² = AC² + x²
AC ² = 81 - x²
Now in ΔADC.
AD² = AC² + DC ²
As AC ² = 81 - x²
DC = 13 - x
AD=√88
(√88)²=81-x²+(13-x)²
(By using the formula (a + b)² = a² + b² + 2ab )
88=81-x²+13²-2*13*x+x²
88=81-x²+13²-26x+x²
88-81 - 169 = -26x
88-250 =-26x
-162 = - 26x
x=162/26
x = 6.2 (Approx)
Therefore the value of x is 6.2 units.

What is 50% dilated?
Dilation is a process of changing the size of an object or shape by decreasing or increasing its dimensions by some scaling factors.
What is Dilation ?Dilation is a transformation, which is used to resize the object. Dilation is used to make the objects larger or smaller. This transformation produces an image that is the same as the original shape. But there is a difference in the size of the shape. A dilation should either stretch or shrink the original shape. This transformation is expressed by the term “scale factor.The basic formula to find the scale factor of a dilated figure is: Scale factor = Dimension of the new shape ÷ Dimension of the original shape.A dilation (similarity transformation) is a transformation that changes the size of a figure. It requires a center point and a scale factor , k . The value of k determines whether the dilation is an enlargement or a reduction. If |k|>1 , the dilation is an enlargement.

Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y = [tex]\frac{5}{3}[/tex] x - [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given m = [tex]\frac{5}{3}[/tex] , then
y = [tex]\frac{5}{3}[/tex] x + c ← is the partial equation
to find c substitute (4, 6 ) into the partial equation
6 = [tex]\frac{5}{3}[/tex] (4 ) + c = [tex]\frac{20}{3}[/tex] + c ( subtract [tex]\frac{20}{3}[/tex] from both sides )

What is midpoint formula Class 9?
In class 9, the midpoint formula is a mathematical formula used to find the midpoint of a line segment given the coordinates of its two endpoints. The midpoint formula is:
(x, y) = ( (x1 + x2) / 2, (y1 + y2) / 2)
Where (x1, y1) and (x2, y2) are the coordinates of the two endpoints of the line segment, and (x, y) are the coordinates of the midpoint.
For example, if the coordinates of the two endpoints of a line segment are (3, 4) and (7, 10), you can use the midpoint formula to find the coordinates of the midpoint:
(x, y) = ( (3 + 7) / 2, (4 + 10) / 2)
(x, y) = (5, 7)
So the midpoint of the line segment with endpoints (3, 4) and (7, 10) is (5, 7)
The midpoint formula is used in class 9 to find the midpoint of a line segment in coordinate geometry. It's a simple way to find the point which is exactly in the middle of two given points. It can be used to find the center of a circle if we know the coordinates of two points on the circumference.

AI's Auto Shop charges $149 for parts and $53 per hour of labor for a repair job. Edna's Engine Repair charges a flat fee of $280 for the same job.
a. Write a system of equations to represent the situation.
b. Graph the system of equations.
c. Which shop is cheaper if the job takes 2 hours? 3 hours?
Answer:
AI's Auto Shop: y = 149 + 53x
Edna's Engine Repair: y = 280
Explanation:
The system of equations represent the costs of the two different repair shops. The first equation, y = 149 + 53x, represents the total cost of AI's Auto Shop. The variable x represents the number of hours of labor required, and the variable y represents the total cost. The second equation, y = 280, represents the flat fee charged by Edna's Engine Repair.
The graph of the system of equations would show two lines, one for each equation. The line for AI's Auto Shop would have a slope of 53 and a y-intercept of 149, representing the cost of parts and hourly labor. The line for Edna's Engine Repair would be a horizontal line at y = 280, representing the flat fee charged.
When the job takes 2 hours, AI's Auto Shop would charge $149 + $53*2 = $255 and Edna's Engine Repair would charge $280. So, AI's Auto Shop would be cheaper.
For a job that takes 3 hours, AI's Auto Shop would charge $149 + $53*3 = $308 and Edna's Engine Repair would charge $280. So, AI's Auto Shop would be more expensive.

O D. f¹(x) = (x+4)²; x≥0
The inverse of the function f(x) and its domain include the following: D. f⁻¹(x) = (x + 4)²; x ≥ 0.
What is an inverse function?In Mathematics, an inverse function simply refers to any type of function that is typically generated by reversing the mathematical operation in a given function (f(x)).
In order to determine the inverse of any function, you should swap both the input value (x-value) and output value (y-value) as follows;
f(x) = √x - 4
y = √x - 4
x = √y - 4
√y = x + 4
Taking the square of both sides of this inverse function, we have:
f⁻¹(x) = (x + 4)²
For the domain of this function, we have:
f(x) = √x - 4
When x= 0, we have:
f(0) = √0 - 4
f(0) = 0.
