round 283,657 to the nearest thousand
284,000
(You would round up one because the number right before the thousands place is the hundred, which in our case, is above 4. As such, we are going to round up to 284,000.)
Hope I could help! :)
When rounding 283,657 to the nearest thousand, we look at the hundreds digit which is 6. Since it is greater than 5, we round up, resulting in a final rounded number of 284,000.
Explanation:To round 283,657 to the nearest thousand, we look at the hundreds place to decide whether to round up or down. Since the hundreds digit is a '6' (which is greater than 5), we round up to the next thousand. Therefore, 283,657 rounded to the nearest thousand is 284,000.
Rounding rules dictate that if the digit to the right of the target rounding place is 5 or greater, we round up the target digit by one. In this case, we're rounding to the nearest thousand, so we look at the hundreds place which is a 6. Since it is greater than 5, we add one to the thousands place, changing 283,000 to 284,000, and set all the following digits to zero, giving us our final rounded number.

Which of these numbers has the greatest absolute value? -43, -23, 0, 18 A) -43 B) -23 C) 0 D) 18
Answer:
A) -43
Step-by-step explanation:
The absolute value is the distance from 0... which means you take the number and if there's a negative sign in front of it, you remove it.

The area of a rectangle is 4g^2- h^2. Use Factoring to find the dimensions of the rectangle.
Answer: [tex](2g+h)[/tex] and [tex](2g-h)[/tex]
Step-by-step explanation:
The area of a rectangle is obtained by multiplying its lenght by its width.
You know that the area of this rectangle is [tex]4g^2- h^2[/tex], then you need to apply the Difference of squares to find the dimensions of this rectangle.
Remember that the Difference of squares is:
[tex]a^2-b^2=(a+b)(a-b)[/tex]
Then, applying this, you get:
[tex]4g^2- h^2=(2g+h)(2g-h)[/tex]
Therefore, now you know that the dimensions are:
[tex](2g+h)[/tex] and [tex](2g-h)[/tex]
the length and breadth of rectangle are [tex]2g - h[/tex] and [tex]2g + h[/tex] respectively
The given expression for the area of the rectangle is [tex]4g^2 - h^2[/tex]
This expression is a difference of squares, which can be factored using the formula: [tex]a^2 - b^2 = (a - b)(a + b)[/tex]
Now by comparing both equations we can factor as follows:
[tex]4g^2 - h^2 = (2g)^2 - h^2\\\\4g^2 - h^2 = (2g+h)(2g-h)[/tex]
We know that area of a rectangle is a product of its length and breadth so we can say that:
Length: 2g - h
Breadth: 2g + h
So, the length and breadth of rectangle are [tex]2g - h[/tex] and [tex]2g + h[/tex] respectively

yvette measured the length of her driveway to be 5 meters long. Which of these is an equivalent measurement?
A. 0.07 mi
B. 15.5 yd
C. 16.4 ft
D. 585 in.
the answer is c. 16.4 feet in 5 meters
Answer:
16.4 ft
Step-by-step explanation:
We are given that Yvette measured the length of her driveway to be 5 meters long.
We have to find that which is equivalent to given length in given options.
Measurement of length = 5 m
We know that 1 meter =3.28 foot
1 meter=1.09 yard
1 meter =39.37 inches
5 m= [tex]5\times 3.28=16.4 ft[/tex]
5 m=[tex]5\times .109=5.45 yard[/tex]
5 m=[tex]5\times 39.37=196.85 inches[/tex]
Hence, measurement of length =5 m =16.4 ft
i need help Distribute 7(5-3). What is the expanded form?
Question 3 options:
a (7 x 3) - (7 x 5)
b (7 + 5) - (7 + 3)
c (7 x 5) - (7 x 3)
d(7 x 5) + (7 x 3)
Answer: The answer to your question is C. (7*5) - (7*3)
Step-by-step explanation: because when you have an expression or equation in parentheses, you apply the distributive property to get rid of the parentheses:
The problem will now look like this:
[tex]7(5-3)= (7*5) - (7*3)[/tex]
And if they asked you for the answer in a whole number, it would be 14 because
7*5=35 and 7*3=21
35-21=14
So, therefore, the expanded form would be (7*5) - (7*3)
given the vector v has an initial point (-2,-6) and a terminal point of (1,2) write vector v as a linear combination of the standard unit vector i and j.
Answer:
v=3i+8j
Step-by-step explanation:
The given the vector v has an initial point (-2,-6) and a terminal point of (1,2).
To find the components of vector v, we subtract the terminal points from the initial point to obtain.
v=<1,2>-<-2,-6>
v=<1--2,2--6>
v=<1+2,2+6>
v=<3,8>
As a linear combination of the standard unit vectors.
v=3i+8j

Answer:
y = -3/2 x +3
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
3x+2y = 6
Subtract 3x from each side
3x-3x+2y = -3x+6
2y = -3x+6
Divide each side by 2
2y/2 = -3x/2 +6/2
y = -3/2 x +3
This is in slope intercept form where the slope is -3/2 and the y intercept is 3

The hypotenuse of a right angle triangle measures 12 units. what is the maximum possible area in square units, of the triangle ?
Answer:
The maximum possible area of the triangle is 36 units²
Step-by-step explanation:
Let
x, y the legs of the right triangle
Applying the Pythagoras Theorem
[tex]12^{2}=x^{2}+y^{2}\\\\144=x^{2}+y^{2}[/tex]
[tex]y=\sqrt{144-x^{2}}[/tex] ----> equation A
The area of the right triangle is equal to
[tex]A=\frac{1}{2}xy[/tex] ----> equation B
substitute equation A in equation B
[tex]A=\frac{1}{2}x(\sqrt{144-x^{2}})[/tex]
Using a graphing tool
The vertex of the graph is a maximum
That means
The x-coordinate of the vertex is the value of x for the maximum possible area of the triangle
The y-coordinate of the vertex is the maximum possible area of the triangle
The vertex is the point (8.485,36)
see the attached figure
therefore
The maximum possible area of the triangle is 36 units²
Is the inverse a function
Answer:
Is not a function
Step-by-step explanation:
A relation is a function if each value of the input set (domain) is assigned only one value of the output set (range)
Given a function [tex]f(x)[/tex], the inverse of f denoted [tex]f ^ {- 1}(x)[/tex] is a function only if f(x) is a one-to-one function. This means that there are not in the domain of [tex]f(x)[/tex] two distinct values of x that produce the same value of y.
In the graph of f(x) you can see that the function is not one-to-one. Since [tex]f(x) = (-x)[/tex] for all x.
For example:
[tex]f(1) = f (-1)\\\\f (2) = f (-2)\\\\[/tex]
Observe the attached graph
In general, the inverse of a quadratic function f(x) is not a function

length of altitude=16/2=8
The question is incomplete, here is a complete question.
Triangle FGH is an isosceles right triangle with a hypotenuse that measures 16 units. An altitude, GJ, is drawn from the right angle to the hypotenuse.
What is the length of GJ?
A. 2 units
B. 4 units
C. 6 units
D. 8 units
Answer : The correct option is, (D) 8 units
Step-by-step explanation :
Given:
Length FH = 16 unit
As we know that a altitude between the two equal legs of an isosceles triangle creates right angles is a angle and opposite side bisector.
Thus,
Length FJ = Length HJ = [tex]\frac{16}{2}[/tex] = 8 units
As, the triangle is an isosceles. So, length GF = length GH = x unit
First we have to determine the value of 'x'.
Using Pythagoras theorem in ΔFGH :
[tex](Hypotenuse)^2=(Perpendicular)^2+(Base)^2[/tex]
[tex](FH)^2=(GF)^2+(GH)^2[/tex]
Now put all the values in the above expression, we get :
[tex](16)^2=(x)^2+(x)^2[/tex]
[tex]256=2x^2[/tex]
[tex]x^2=128[/tex]
[tex]x=8\sqrt{2}[/tex]
Thus, length GF = length GH = x unit = [tex]8\sqrt{2}[/tex]
Now we have to determine the length GJ.
Using Pythagoras theorem in ΔGJH :
[tex](Hypotenuse)^2=(Perpendicular)^2+(Base)^2[/tex]
[tex](GH)^2=(GJ)^2+(HJ)^2[/tex]
Now put all the values in the above expression, we get :
[tex](8\sqrt{2})^2=(GJ)^2+(8)^2[/tex]
[tex]128=(GJ)^2+64[/tex]
[tex](GJ)^2=128-64[/tex]
[tex](GJ)^2=64[/tex]
[tex]GJ=\sqrt{64}[/tex]
[tex]GJ=8[/tex]
Thus, the length of GJ is, 8 units.

What is a linear equation?
A linear equation has one or two variables. No variable in a linear equation is raised to a power greater than 1.No variable is used as the denominator of a fraction. A linear equation is defined as an equation that is written in the form of ax+by=c. When solving the system of linear equations, we will get the values of the variable, which is called the solution of a linear equation.
solving this we will get the valve of Y if x is given.

The measure of a vertex angle of an isosceles triangle is 120° and the length of a leg is 8 cm. Find the length of a diameter of the circle circumscribed about this triangle.
Answer in CM, please. Thanks!
Answer:
16cm
Step-by-step explanation:
To find the diameter we must first find the radius and multiply by 2.
The isosceles triangle that has the length of a leg to be 8cm and a vertex angle of [tex]120\degree[/tex] that has been circumscribed is shown in the attachment.
We draw a line from the vertex of the isosceles triangle that bisects the base through the center O of the circle.
This implies that [tex]m\angle OAC=60\degree[/tex].
Based on this [tex]m\angle ACO=60\degree[/tex] because the two radii are equal.
It follows that:[tex]m\angle AOC=60\degree[/tex] because sum of angles in a triangle must be 180 degrees.
This means that, triangle AOC is an equilateral triangle, hence all sides are equal.
One side of this equilateral triangle happens to be the side of the leg of the isosceles triangle which is 8cm.
It follows that, the radius of the circle is 8cm.
Therefore the diameter of the circle is 16cm
