The proper rounding of 190.4592785 to the nearest tenth gives 190.4.
What is round to the tenth?Look at the next place value to the right to round a number to the closest tenth (the hundredths). Simply eliminate all the numbers to the right if the number is 4 or fewer.
Add one to the digit in the tenth place if the number is five or above, and then eliminate all the digits to the right.
To round digits to the tenth means after the decimal there is only one number. It is tenth place.
190.4592785 = 190.4
Therefore, the nearest round to the tenth is 190.4.

Please help me with this graph.
Answer:
f(x) = 1/4(x + 4)(x - 2)²Step-by-step explanation:
Let's analyze the graph.
We observe that:
It is an increasing function, so leading coefficient is positive,It has one x-intercept (- 4, 0), It has one touching point at x-axis (2, 0), so it has at least multiplicity of 2,It has a y-intercept (0, 4), It has a local maximum (- 2, 8).Based on our observations, the least degree polynomial function will have the form of:
f(x) = a(x + 4)(x - 2)²To find the value of a we'll use the y-intercept:
4 = a(0 + 4)(0 - 2)²4 = a*16a = 4/16a = 1/4Let's prove it with local maximum:
8 = 1/4(- 2 + 4)(-2 - 2)²8 = 1/4*2*168 = 8So the function is:
f(x) = 1/4(x + 4)(x - 2)²(03.01 LC)

Nakeisha and Katherine work at a dry cleaners ironing shirts. Nakeisha can iron 20
shirts per hour, and Katherine can iron 10 shirts per hour. Nakeisha and Katherine
worked a combined 10 hours and ironed 140 shirts. Graphically solve a system of
equations in order to determine the number of hours Nakeisha worked, x, and the
number hours Katherine worked, y.
Two or more algebraic equations that share variables, such as x and y, are said to be simultaneous equations. Since the equations are solved simultaneously, they are known as simultaneous equations. These equations alone could have an endless number of solutions.
The equations that can be used to calculate how many hours Caleb and Landon work are as follows:Eq. 1: 20c + 10l = 320
Equation 2: c - l = 10
where x = total hours Caleb puts in y hours of work. Landon has a job
The total number of shirts that Caleb and Landon iron in an hour depends on how many hours each of them works overall.
The total number of shirts they can both iron is equal to the product of the number of shirts Caleb can iron in an hour and the number of hours he worked (shirts that Landon can iron in an hour x number of hours Landon worked)
Eq. 1: 20c + 10l = 320
Equations 1 and 2 must be solved jointly because they are simultaneous equations, and doing so will yield the solution.

The telephone company purchased 95 yards of wire for $1,235 in September. They plan on making a purchase of 285 yards in October. How much will the October purchase cost?
285 yards of wire purchased in October will cost $3705.
We will use unitary method for calculation.
The cost of one yard of wire = total cost ÷ length of wire × unit length
Cost of one yard of wire = 1235 ÷ 95 × 1
Performing division on Right Hand Side of the equation
Cost of one yard of wire = $13
Now calculating the cost for purchase of 285 yards of wire in October.
Cost of wire in October = 285 × 13
Performing multiplication on Right Hand Side of the equation
Cost of wire in October = $3705
Thus, the cost of purchase in October is $3705.

The image of point (4,4)under a translation is (6,0). Find the coordinates of the image of the point (1,-4) under the same translation
The coordinates of the point's image (1,-4) under the same translation are (2, 0)
What is translation?A translation is a geometric transformation that moves all points of a figure, shape, or space by the same amount in the same direction. A translation can also be thought of as adding a constant vector to each point or shifting the coordinate system's origin. A translation is a type of transformation that involves sliding each point in a figure the same distance in the same direction. A translation is a transformation that moves every point in a figure in the same direction by the same amount. For example, this transformation shifts the parallelogram 5 units to the right and 3 units up. It is written as ( x , y ) → ( x + 5 , y + 3 ) .
Therefore,
The coordinates of the point's image (1,-4) under the same translation are (2, 0)
The x coordinate increased by 1, and the y coordinate increased by 4.
Now, do these same transformations to the other point, (1, -4)

Define reflection.
A flip is a term for a reflection in geometry. The shape is mirrored in a reflection. The line of reflection is a line through which an image will reflect. Every point in a figure is said to reflect the other figure if and only if it is equally spaced from every corresponding point in the other figure.
A line of reflection is required to perform a geometry reflection; the resulting orientation of the two figures is the opposite. The figures' corresponding parts are spaced at the same distance apart from the reflection axis. Ordered pair rules are reflected along the x-axis at (x, -y), the y-axis at (-x, y), and the line at y=x.

Which value of x is in the domain of f(x) = √x – 11?
-
A. X=0
B. x= -4
C. x= 13
D. x = 10
Answer:
C: x = 13
Step-by-step explanation:
It looks like the question is f(x) = sqrt(x - 11)
DOMAIN
The domain of a function refers to values of x that the function can graph and give a definite y value for. Functions can graph x values that do not result in undefined or complex numbers.
If that is the case then x would have to be greater than or equal to 11 because you can not get the square root of negative numbers unless you want to deal with complex numbers.
13 - 11 >= 0 so it is the answer.

What are angles?An angle is a figure in Euclidean geometry made up of two rays that share a common endpoint and are referred to as the angle's sides and vertex, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles. Based on the measurement, there are different kinds of angles in geometry. The names of fundamental angles include acute, obtuse, right, straight, reflex, and full rotation.So, the value of x will be:
∠BCE = 5x° and ∠ECD = 40°, and we can see in the diagram that the ∠BCD = 90°.Then, the equation formed will be:
∠BCE + ∠ECD = ∠BCD 5x° + 40° = 90°5x° = 90 - 405x° = 50x = 50/5x = 10So, ∠BCE = 5x° ⇒ 5(10) = 50°.

What is triangle?
A triangle in geometry is a three-sided polygon with three edges and three vertices. The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic. This characteristic is known as the triangle's angle sum property.
Given in the question,
∠J = (8x+6)°
∠K = (2x+2)°
∠L = (4x+4)°
We know that, the sum of the all angles in triangle is 180°
So, in triangle JKL
∠J + ∠K + ∠L = 180
Putting the values from the question. we get,
(8x+6) + (2x+2) + (4x+4) = 180
14x + 12 = 180
(180 - 12)/14 = x
x = 12
Putting the value of x in given value of angle L.
∠L = 4x+4
∠L = 4(12)+4
∠L = 48 + 4
∠L = 52°
Hence the angle L is measured as 52 degrees.

multiply 13.8 times her regular 40 hour work week plus 28 hours of overtime pay
(13.8•40)+(13.8•1.5)•(hours of overtime)=gross pay

x + (x + 30) + 2x = 180. (combine x and 2x)
3x + (x + 30) = 180. (combine 3x and x, 30 cant combine)
4x + 30 = 180. (subtract 30 from both)
4x = 150. (divide both sides by 4)
