can the sides of a triangle have lengths 3, 4, and 7?
Answers
Answer:
The length of the third side of a triangle must always be between (but not equal to) the sum and the difference of the other two sides. ... Therefore, the third side length must be greater than 4 and less than 8. Because 7 is greater than 4 and less than 8, it is possible for these to be the side lengths of a triangle.
Step-by-step explanation:
The sides of length 3, 4 and 7 does not form triangle.
What is a triangle?Three edges, three angles, and three vertices are the characteristics of a triangle in geometry. In geometry, it is a basic figure.
The sum of the angles of a triangle is always 180°
Given that,
Sides of a triangle are 3, 4 and 7.
Since, the one side of a triangle is greater than the difference of other two sides and less than sum of the two sides.
Implies that,
If side 3 is taken, then 3 should greater than difference of 7 and 4, also less than sum of 7 and 4.
Implies that,
7 - 4 < 3 < 7 + 4
3 < 3 < 11
Here, the condition does not satisfy. Therefore, The given lengths do not make triangle.

Which system of linear equations represents the lines graphed below?
Answers
Answer:
B
Step-by-step explanation:
I took the test and got it right
Answer:
Option D is the correct answer.
Step-by-step explanation:
Both the lines are intersecting each other at point (-6, 4)
So, x = - 6 & y = 4
Let us plug x = - 6 in the equation [tex] y =-\frac{1}{3} x + 2[/tex]
We find that:
[tex] y =-\frac{1}{3} (-6) + 2[/tex]
[tex] y =-(-2) + 2[/tex]
[tex] y = 2 + 2[/tex]
[tex] y = 4[/tex]
So, when x = - 6, the value of y is 4.
Since, second equation of option D is invisible, hence I can't provide any explanation for the same.

Answers
Answer:
The correct answer is 2 ( 5 × w )
Explanation:
Area of a rectangle = length × width
The length = 5 feet
The width = w feet
So the area = 5 × w
Then, he has to double the length and width, so its 2 times the length and width. So the new expression will be:
Area = 2 ( 5 × w )

Determine whether the quadratic function show below has a minimum or maximum then determine the minimum or maximum value of the function
f(x) = 3x^2 - 18x + 29
Answers
Answer:
The quadratic has a minimum value.
The minimum value is at (3, 2).
Step-by-step explanation:
We are given the quadratic function:
[tex]f(x)=3x^2-18x+29[/tex]
First, since the leading coefficient is positive, this quadratic function will be concave up.
Hence, we will have a minimum value.
The minimum or maximum value is the vertex of the quadratic. The vertex is given by:
[tex]\displaystyle \Big(-\frac{b}{2a},f\Big(-\frac{b}{2a}\Big)\Big)[/tex]
In this case, a = 3, b = -18, and c = 29. Thus, the x-coordinate of the vertex is:
[tex]\displaystyle x=-\frac{-18}{2(3)}=\frac{18}{6}=3[/tex]
And the minimum value is:
[tex]f(3)=3(3)^2-18(3)+29=2[/tex]

[tex]Surface\ area = 6728.3125(pi)\\\\Surface\ area = 21137.6171211[/tex]
Step-by-step explanation:
The lateral surface area of an object is the surface area of the subject excluding the base and the top of the 3-dimensional figure. The surface area of the object is the 2-dimensional space of an object, in essence, if one was going to wrap the object, the amount of material they would need to cover the object. To find the lateral surface area of a cylinder, one must find the circumference of the circle at the top of the cylinder, and then multiply it by the height of the cylinder. The circumference of a circle is the distance around it, the perimeter.
The formula one would use is,
[tex]A_s = (pi)(r^2)(h)[/tex]
Were (pi) represent the value (3.1415...), (r) represent the radius of the base, that is the distance from the center point of the circle on the base, to the outside distance of the circle. The radius of a circle is always half of the diameter. (h) represents the height of the figure.
[tex]A_s = (pi)(r^2)(h)\\\\= (pi)((\frac{3.5}{2})^2))(13)\\\\= (pi)(1.75)^2(13)\\\\= (517.5625)(13)(pi)\\\\=(6728.3125)(pi)\\\\= ~21137.6171211[/tex]
Determine whether the following equation represents a direct variation If it does, find the constant of variation
2x + 3y = 0
Answers
Given:
The equation is
[tex]2x+3y=0[/tex]
To find:
Whether the equation represents a direct variation. If it does, find the constant of variation.
Solution:
The general equation of direct variation is
[tex]y=kx[/tex] ...(i)
Where, k is the constant of variation.
The equation of direct variation is always true for (0,0).
The given equation is
[tex]2x+3y=0[/tex]
It can be written as
[tex]3y=-2x[/tex]
[tex]y=-\dfrac{2}{3}x[/tex] ...(ii)
For x=0,
[tex]y=-\dfrac{2}{3}(0)[/tex]
[tex]y=0[/tex]
The given equation is true for (0,0). So, it represents a direct variation.
On comparing (i) and (ii), we get
[tex]k=-\dfrac{2}{3}[/tex]
Therefore, the constant of variation is [tex]-\dfrac{2}{3}[/tex].

A sculpture is in the shape of a cylinder. The sculpture has a diameter of 10 feet and a height of 21 feet. Which measurement is closest to the total surface area of the sculpture in square feet?
Answers
Answer:did u get the answer?
Step-by-step explanation:sorry
The measurement of total surface area of the sculpture in square feet is 814 square feet.
What is the surface area of a cylinder?The surface area of a cylinder can be calculated by adding the area of its lateral surface to the sum of the areas of its two circular ends. The formula for lateral surface area is given by: 2πrh
where r is the radius of the circular base and h is the height of the cylinder.
Since the diameter of the cylinder is 10 feet, the radius is 10/2 = 5 feet.
So, the lateral surface area of the cylinder = 2 × π × 5 × 21 = 210π square feet.
The area of each circular end is given by πr². Since the radius is 5 feet, the area of each circular end is π × 5² = 25π square feet.
Therefore, the total surface area of the cylinder is 210π + 2 × 25π = 260π square feet.
The value of π is approximately 3.14, so the surface area of the cylinder is approximately 260 × 3.14 = 816.4 square feet.
So, the closest measurement of the total surface area of the sculpture in square feet is 816 square feet.
