Question 4: The length of the diagonal of a square is 6 cm. Find the sides of the square.
Answer:
The length of each side of the square is approximately 4.24 cm.
Explanation:
We can use the Pythagorean theorem to find the length of each side of the square. Let "s" be the length of each side of the square. The diagonal of the square, which is 6 cm, is the hypotenuse of a right triangle whose legs are two sides of the square. So we have:
[tex]s^2 + s^2 = 6^2[/tex]
Simplifying this equation, we get:
[tex]2s^2 = 36[/tex]
Dividing both sides by 2, we get:
[tex]s^2 = 18[/tex]
Taking the square root of both sides, we get:
s ≈ 4.24
Therefore, the length of each side of the square is approximately 4.24 cm.
Triangle UVW is drawn with vertices at U(−1, 1), V(0, −4), W(−4, −1). Determine the coordinates of the vertices for the image, triangle U′V′W′, if the preimage is rotated 90° clockwise.
U′(1, −1), V′(0, 4), W′(4, 1)
U′(−1, −1), V′(−4, 0), W′(1, 4)
U′(1, 1), V′(−4, 0), W′(−1, 4)
U′(−1, 1), V′(0, −4), W′(−4, −1)
The coordinates of the vertices for the image of the triangle U′V′W′ is
U′(1, 1), V′(−4, 0), W′(−1, 4)
How to find the coordinates after transformationTo rotate a point 90 ° clockwise about the origin, we can apply the transformation (x, y) → (y, -x)
So applying this transformation to each vertex of triangle UVW we get
U(−1, 1) → U' = (1, 1)
V(0, −4) → V' = ( -4, 0)
W(−4, −1) → W' = (-1, 4)
Therefore the coordinates of the vertices for the image triangle U'V'W' are U′(1, 1), V′(−4, 0), W′(−1, 4)

The cube root of both sides to solve for x variable is
x = (k - y^3 - z^3)^(1/3)
You can solve for y or z in terms of the other variables by rearranging the original equation.
Given the equation: x^3 + y^3 + z^3 = k.
To solve this equation for one of the variables (x, y, or z), you would need additional information or constraints. However, I can provide you with a general method to express one variable in terms of the others. Let's solve for x:
Step 1: Subtract y^3 and z^3 from both sides of the equation.
x^3 = k - y^3 - z^3
Step 2: Take the cube root of both sides to solve for x.
x = (k - y^3 - z^3)^(1/3)
Now, x is expressed in terms of y, z, and k. If you have any specific values for y, z, and k, you can substitute them into this equation to find the corresponding value of x. Similarly, you can solve for y or z in terms of the other variables by rearranging the original equation.

The spinner will be spun two times.
What is the probability that both spins result in the same color?
Answer: 11/32
Step-by-step explanation:
The formula for finding this is:
(yellow and yellow) or (pink and pink) or (blue and blue)
First find the probability that both spins will be yellow:
2/8 * 2/8 = 1/16
There are 2 yellow spots out of the 8 total spots.
Because you need to spin yellow and yellow, you multiply the two fractions.
This logic applies to pink and blue.
Next pink:
3/8 * 3/8 = 9/64
Blue:
3/8 * 3/8 = 9/64
Find the probability that you will spin yellow or pink or blue:
1/16 + 9/64 + 9/64 = 11/32
Whenever finding the probability of something or something else, add them.

Part 1: methods did not consider the number of repetitions or combinations of the same item that could be used in different outfits. Part 2: Jenny can wear 1,920 different outfits by choosing one blouse, one skirt, one pair of socks, and one pair of shoes at a time from her closet.
How to answer the aforementioned questionsPart 1:
Because they only considered a limited number of clothing items and did not take into account the fact that different combinations of these items could create a larger number of outfits, the methods used in the previous two problems would be inefficient in determining the number of different outfits Jenny could wear.
Part 2:
Using the Fundamental Principle of Counting, the number of different outfits Jenny could wear can be determined by multiplying the number of choices for each clothing item together. Therefore, the total number of different outfits can be calculated as:
6 blouses x 4 skirts x 20 pairs of socks x 4 pairs of shoes = 1,920 different outfits

O The equations are independent because the lines intersect in one point.
The equations are dependent because the lines are the same line.
O The equations are independent because the equations represent parallel lines.
O The equations are dependent because the lines do not intersect.
= -2x+5
Answer:
Step-by-step explanation:
The correct statement about the given equations is: "The equations are dependent because the lines are the same line."
In the equation y = 2x + 5, the slope is 2, which means the line has a positive slope and is upward sloping.
The y-intercept is 5, indicating that the line intersects the y-axis at the point (0, 5).
The equation y = -2x + 5 is equivalent to y = 2(-x) + 5, which has the same form as the first equation but with a negative slope.
However, the equations are still dependent because when you simplify the second equation, you obtain the first equation.
These two equations represent the same line with a different slope. Therefore, they are dependent, and any point that satisfies one equation will satisfy the other equation as well.

What’s the answer to n+19=9
Answer: n= -10
Step-by-step explanation:
n + 19 = 9, so you want to get the variable by itself so you will get rid of the 19, cancelling it by subtracting. So n=9-19 leaving you with -10.
Convert the rectangular coordinates to polar coordinates
(1, -9)
The polar coordinates of (1, -9) are (9.06, -1.47 radians).
To convert from rectangular coordinates to polar coordinates, we can use the following formulas:
r = √(x² + y²)
θ = tan⁻¹(y/x)
where r is the distance from the origin to the point, and θ is the angle between the positive x-axis and the line connecting the origin to the point.
In this case, x = 1 and y = -9. Plugging these values into the formulas, we get:
r = √(1² + (-9)²) = √82 ≈ 9.06
θ = tan⁻¹((-9)/1) ≈ -1.47 radians
Therefore, the polar coordinates of (1, -9) are (9.06, -1.47 radians). The distance from the origin to the point is approximately 9.06 units, and the angle between the positive x-axis and the line connecting the origin to the point is approximately -1.47 radians (or approximately -84.26 degrees).

Okay so this is for my portfolio. I have two figures; a rectangular prism (think cereal box) and a cylinder. Is it possible for the cylinder to have a larger VOLUME than the prism, but a smaller measurement of cubic inches?? (Please say yes )
Step-by-step explanation:
No, it is not possible. Cubic inches are a measurement of volume. If the cylinder has a larger volume, then it also has more cubic inches.
Answer:
no TWT
Step-by-step explanation:
Because these solids have the same height and the same cross-sectional areas at every level, the solids have the same volume due to Cavalieri's principle. The volume of the prism is: V = A B a s e ⋅ h = π r 2 h Therefore, the volume of the cylinder is: V = π r 2 h This should make sense because a cylinder is essentially a circular prism.

Can someone please provide me with both functions? Thank you!
y=√(21+4x²)/3 and y=-√(21+4x²)/3 are the two functions defined by implicity by the equation
The given equation is an equation of an ellipse centered at the origin with a major axis of length 2√7 and a minor axis of length 2√3.
To find two functions defined implicitly by this equation, we can solve for y in terms of x using algebra.
First, we can isolate y²/3 by subtracting x²/7 from both sides:
y²/3 = 1 - x²/7
Multiply by 3 on both sides to eliminate the fraction:
y² = 3 - 3x²/7
y = ±√(3 - 3x²/7)
These are the two functions defined implicitly by the given equation.
The positive square root gives the upper half of the ellipse, while the negative square root gives the lower half.
