Identify the reflection rule on a coordinate plane that verifies that triangle A(-1,7), B(6,5), C(-2,2) and A'(-1,-7), B'(6,-5), C'(-2,-2) triangle are congruent when reflected over the x-axis.
Final answer:
The reflection rule over the x-axis is when a point (x, y) reflects to (x, -y). Applying this rule to triangle A(-1,7), B(6,5), C(-2,2) gives us the reflected points that match the coordinates of A'(-1,-7), B'(6,-5), C'(-2,-2), proving the triangles are congruent.
Explanation:
The student is querying about the reflection of a triangle over the x-axis on a coordinate plane, specifically within the domain of Mathematics. To demonstrate that triangles A(-1,7), B(6,5), C(-2,2) and their reflected counterparts A'(-1,-7), B'(6,-5), C'(-2,-2) are congruent, we will use the reflection rule associated with reflections over the x-axis.
The reflection rule states that when a point (x, y) is reflected over the x-axis, the resulting point will be (x, -y). Applying this rule:
For point A(-1, 7), the reflection over the x-axis would be A'(-1, -7).
For point B(6, 5), the reflection would be B'(6, -5).
For point C(-2, 2), the reflection would be C'(-2, -2).
The reflected points A', B', and C' match the coordinates given for the congruent triangle, thus confirming the triangles are congruent using the reflection rule over the x-axis.

the average number of minutes that it took jermaine to complete his homework assignments for a week in september was 27 minutes, with a mean absolute deviation of 4 minutes. with this informatiom, which statement is true. Pls someone help me
Answer:
On average, Jermaine spent between 23 and 31 minutes on his homework.
On average, Jermaine spent between 23 and 31 minutes on his homework.
What is Mean absolute deviation?This is defined as the average of the absolute deviations from a central point.
In this scenario, the mean absolute deviation
= 27 ± 4 minutes
= 27+4 or 27 - 4
= 31 or 23 minutes.
Therefore we can infer that Jermaine spent between 23 and 31 minutes on his homework.

What is the value of a for the following circle in general form? x^2+y^2+ax+by+c=0
The 'a' in the equation refers to the coefficient influencing the horizontal shift of a circle's center. To find 'a', you often need specifics about the circle, such as its center or radius. When such information is provided, the quadratic formula can be used to solve it.
Explanation:The given equation x2+y2+ax+by+c=0 represents the general form of a circle equation. The value of 'a' is a coefficient that impacts the horizontal shift of the circle along the x-axis. Unfortunately, without specific values attached, it is impossible to directly calculate 'a'. Nevertheless, if the equation is compared to the completed square form of a circle equation, i.e., (x-h)2+(y-k)2=r2, you can ascertain that 'a' would be -2h, where h is the x-coordinate of the circle's center.
In specific examples, for instance, if a = 1, b = 0.0211, and c = -0.0211, we can solve for x using the quadratic formula -b ± √b² - 4ac divided by 2a yielding -0.0211 ± √(0.0211)2 − 4(1)(−0.0211)/2(1), where 'a', 'b', 'c' are the coefficients from the equation of a circle in its general form.

Milton got a paperweight like the one shown below. He needs to fill it with sand to give it weight.
If a = 2 inches, what is the volume of the paperweight?
A.24 in3
B.56 in3
C.16 in3
D.32 in3
Solution:
Given that, Milton got a paperweight like the one shown in the figure.
The Paper Weight is in the shape of a cuboid and a cube.
Length and breadth of cuboid is a and height of the cuboid is 2a, whereas side of cube is a.
The volume of sand required to fill in the Paper Weight , is equal to the volume of the Paper weight,
Volume of Paper Weight = Volume of cube + Volume of cuboid
We know that, Volume of cube =[tex] (side)^{3} [/tex]
and , Volume of Cuboid = [tex] length \times breadth \times height [/tex]
Volume of Paper Weight = [tex] a^{3}+ (a\times a \times2a)= a^{3} +2a^{3} = 3a^{3} [/tex]
Given that , a = 2 inches , then Volume of Paper Weight = [tex] 3 \times (2)^{3}= 3\times 8 = 24 [/tex]
[tex] 24 \: in^{3} [/tex] is the volume of the paperweight.
