b. reflection over the y-axis
c. translation
2) and triangle T2 is transformed into trinagle T3 by
a. dilation with scale factor 1/2
b. reflection over the x-adis
c. rotation
Answers
Answer:
1) The correct option is;
b. Reflection over the y-axis
2) The correct option is;
a. Dilation by a scale factor of 1/2
Step-by-step explanation:
1) The rule for reflection over the y-axis is given as follows;
Given the point of the preimage before the reflection = (x, y), the point of the image after the reflection will be (-x, y)
The coordinate of a point on T1 is (-2, 4). The coordinate of similar point in T2 is (2, 4) which satisfies the rule for reflection over the y-axis
2) The length of a side in triangle T2 is given by the formula for finding the length, l, of segments between coordinate points as follows;
[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Point 1, (x₁, y₁) = (2, 4)
Point 2, (x₂, y₂) = (6, 2)
The length = √((2 - 4)² + (6 - 2)²) = 2·√5
The length of the corresponding side in T3 is given as follows;
Point 1, (x₁, y₁) = (1, 2)
Point 2, (x₂, y₂) = (3, 1)
The length = √((1 - 2)² + (3 - 1)²) = √5
The length of of a side T3 = 1/2 of the length of a side of T2
Therefore. triangle T2 is transformed into triangle T3 by dilation with a scale factor of 1/2.

Sylvia has 51.78 pounds of dirt. She has 20 buckets and would like to put 2.56 pounds of dirt into each bucket. Are there enough buckets for all of the dirt to be in a bucket?
Answers
Answer:
There isn't enough buckets for all of the dirt to be in a bucket.
Step-by-step explanation:
From the question,
She has 20 buckets and would like to put 2.56 pounds of dirt into each bucket.
Hence, the total number of dirt that can be in the 20 buckets is
20 × 2.56
= 51.20 pounds of dirt
Slyvia has 51.76 pounds of dirt.
51.76 - 51.20
= 0.56 pounds of dirt.
From the above calculation we can say that there isn't enough buckets for all of the dirt to be in a bucket

Explain how the volume of a right cone relates to the volume of a cylinder with the same base
and height. Use diagrams and volume formulas to explain the relationship.
Answers
Answer:
its 1/3 of the volume of a cyinder with the same base
Step-by-step explanation:
a pyramid has the same policy with prisms of the same base
Volume is a three-dimensional scalar quantity. If the radius and the height of a cone and a cylinder are the same, then the volume of the cylinder is thrice the volume of the cone.
What is volume?
A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
Assume a cone and a cylinder such that the radius of the base of both the figures is r units, while the height of the cone and cylinder both is h units.
The volume of the cone with radius r units and height h units now can be written as,
Volume of the cone = (1/3) × π × r² × h units³
The volume of the cylinder with a radius of r units and the height of h units now can be written as,
Volume of the Cylinder = π × r² × h units³
Taking the ratio of the volume of the cone and the volume of the cylinder,
Volume of the cone/Volume of the cylinder = (1/3)πr²h units³ / πr²h units³
Volume of the cone/Volume of the cylinder = 1/3
Volume of the cylinder = 3 × Volume of the cone
Hence, if the radius and the height of a cone and a cylinder are the same, then the volume of the cylinder is thrice the volume of the cone.

When = 3, what will the value for y be for the equation - 4x + 5y = 18?
Answers
If x equals 3 then y must equal 1.2
Answer: y=6
-4(3)+5y=18
-12+5y=18
add 12 to both sides
-12+5y+12=18+12
5y=18+12
5y=30
divide both sides by 5
5y÷5=30÷5
y=30÷5
y=6
