Answer:
A) Reflection.
Step-by-step explanation:
From the figure shown, we can see that the blue triangle is flipped about the x-axis to form the red triangle.
When an object is flipped about a line, then this transformation is called reflection about that line.
Thus, we can say that reflection is taking place in the figure shown in which the x-axis is acting like a mirror. The blue triangle is the pre-image and the red triangle is the image after reflection.
The reflection about x-axis is given by:
We can check the co-ordinates of the triangles and confirm the the transformation occurring
Points of pre-image triangle:
Points of image triangle
Thus, the transformation is reflection.
Answer:
False.
Step-by-step explanation:
A tangent is a line that only touches exactly one point of the circle. (The outer edge) :)

Answer:
Step-by-step explanation:
Let w represent the width of the rectangle. Then the length is 3w+1 and the area is ...
w(3w+1) = 52
3w² +w -52 = 0
To factor this equation, we need factors of 3·52 = 156 that have a difference of 1. These values are 12 and 13, so we can rewrite the equation as ...
3w² +13w -12w -52 = 0
w(3w +13) -4(3w +13) = 0
(w -4)(3w +13) = 0
The positive value of w that makes a factor zero is ...
w = 4
Then the length is 3w+1 = 3(4) +1 = 13.
The length is 13 ft; the width is 4 ft.
It all depends on what you are comparing it to... if you want what fraction of a meter it is...
There are 10 decimeters per 1 meter so 1 dm is 1/10 of a meter which means 6 dm = 6 × 1/10 = 6/10 = 3/5
6 dm = 3/5 m
Answer:
3:16
Step-by-step explanation:
5 red marbles.
16 black marbles.
3 green miniature balls.
9 yellow miniature balls.
We want to determine the ratio of the number of the minimum balls to the number of black marbles in the jars.
The minimum of a set of a number is the lowest value in that set of number. e.g. the minimum of 2,5,1 and 6 is 1.
Minimum Number of balls=3
Number of Black Marbles=16
Ratio of the number of the minimum balls to the number of black marbles in the jars is therefore given as:
3:16
