Which of the following two-dimensional shapes can be rotated to create a sphere?
A. Triangle
B. Square
C. Circle
D. Ellipse
please give an explanation and not just a letter or answer. Thank you.
The shape that can be rotated to create a sphere is the circle (option C).
A sphere is a three-dimensional object with all points equidistant from its center. When a circle is rotated about its center axis, it creates a three-dimensional shape that perfectly matches the definition of a sphere.
Let's consider the other options and why they cannot be rotated to form a sphere:
A. Triangle: A triangle is a two-dimensional shape with straight sides. Rotating a triangle around any axis would not result in a three-dimensional shape with all points equidistant from its center, which is the defining characteristic of a sphere.
B. Square: Similarly, a square is a two-dimensional shape with straight sides. Rotating a square around any axis would not create a sphere, as it would still retain its flat, planar nature.
D. Ellipse: An ellipse is a two-dimensional shape resembling a squashed or stretched circle. Rotating an ellipse would not result in a sphere, as it would still retain its elliptical shape.
Therefore, the shape that can be rotated to create a sphere is the circle (option C) due to its symmetrical and curved nature.

A car travels 15 km in 13 minutes.
What is its average speed in km/h?
Give your answer rounded to 1 decimal place.
Answer:
69.2km
Step-by-step explanation:
15km ÷ 13 mins = 1.153km (Average speed)
1 hour = 60mins
1.153km x 60 = 69.18km (Average speed in km/h)
69.18km = 69.2km (Rounded to 1 dp)

find the slope of the line going through the point (0,3) and (0,4)
Answer:
undefined
Step-by-step explanation:
To find the slope of the line between two points, use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line passes through, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point the line also passes through. Therefore, use the x and y values of the points (0,3) and (0,4) to find the slope. Substitute them into the formula in the right order:
[tex]\frac{(4)-(3)}{(0)-(0)} \\= \frac{4-3}{0-0}\\=\frac{1}{0}[/tex]
However, we can't divide 1 by 0. Therefore, the slope is undefined. (You could also graph the points to see that they form a vertical line, and all vertical lines have an undefined slope.)
A recipe for sparkling grape jucie calle for 1 1/2 quarts of sparkling water and 3/4 quart of grape jucie. How much sparkling water would you need to mix with 9 quarts of grape jucie?
Answer: 18 quarts of sparkling water
Step-by-step explanation:
From the question, we are informed that a recipe for sparkling grape jucie calle for 1 1/2 quarts of sparkling water and 3/4 quart of grape jucie.
When there's an increase in the quarts of grape juice to 9, it simply means that the former grape juice has been multiplied 12 times (9 ÷ 3/4 = 9 × 4/3 = 12).
Therefore, we would also multiplybl the sparkling water given by 12 to get the new quantity needed. This will be:
= 1 1/2 × 12
= 3/2 × 12
= 18 quarts of sparkling water

What equation represents the slope intercept form of the line below Y intercept =(0,-2) slope = 2/3
Answer: [tex]y = \frac{2}{3} x - 2[/tex]
Step-by-step explanation:
The slope intercept form is y = mx + b
Where m is our slope and b is our y-intercept
We're given a slope of 2/3
We're given a y-intercept of -2
Substituting into y = mx + b gives
[tex]y = \frac{2}{3} x - 2[/tex]
Answer:
y = (2/3)x - 2
Step-by-step explanation:
Use the slope-intercept form y = mx + b. Here b = -2 and m = 2/3. Making these replacements, we get:
y = (2/3)x - 2
Evaluate the following expression when x = -5 and y = -12. | 4x^2 - 2y |

Explain the steps when solving for the variable y
12x+2y=18
Answer:
Simplifying
12x + 2y = 18
Solving
12x + 2y = 18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
12x + 2y + -2y = 18 + -2y
Combine like terms: 2y + -2y = 0
12x + 0 = 18 + -2y
12x = 18 + -2y
Divide each side by '12'.
x = 1.5 + -0.1666666667y
Simplifying
x = 1.5 + -0.1666666667y
Answer:
Hi
Step-by-step explanation:
First, you need to subtract both sides by 12x
12x+ 2y=18
-12x -12x
That will give you: 2y= 18-12x
Next, you need to deviede both sides by 2
2y/2= 18-12x/2
That gives you the answer:
y= 18-6x

which products result in difference of squares
(x-y)(y-x)
(6-y)(6-y)
(3+xz)(-3+xz)
(y^2-xy)(y^2+xy)
Answer:
[tex](3+xz)(-3+xz)[/tex]
[tex](y^2-xy)(y^2+xy)[/tex]
Step-by-step explanation:
The Difference of Squares
Any difference of two squared monomial results in a factored form like shown below:
[tex]a^2-b^2=(a-b)(a+b)[/tex]
Similarly:
[tex](a-b)(a+b)=a^2-b^2[/tex]
For a product of binomials to be a difference of squares, they must be in the described form.
------------------------
(x-y)(y-x) can be rewritten as:
-(x-y)(x-y)
Since both binomials are identicals, the product will not result in a difference of squares.
-----------------------
(6-y)(6-Y)
Since both binomials are identicals, the product will not result in a difference of squares.
-----------------------
(3+xz)(-3+xz) can be rewritten as:
(xz+3)(xz-3). This product is a sum multiplied by a difference of the very same terms, thus the result is a difference of squares:
[tex](3+xz)(-3+xz)=(xz)^2-9[/tex]
-----------------------
[tex](y^2-xy)(y^2+xy)[/tex]. This product is a sum multiplied by a difference of the very same terms, thus the result is a difference of squares:
[tex](y^2-xy)(y^2+xy)=y^4-(xy)^2[/tex]
-----------------------
Summarizing:
(3+xz)(-3+xz)
[tex](y^2-xy)(y^2+xy)[/tex]
