John gave half of his stamps to Jim. Jim gave gave half of his stamps to Carla. Carla gave 1/4 of the stamps given to her to Tho
1 answer:
This question wants you to reverse the operations that occurred.
Start with 12 stamps.
Divide this number by 3/4. This represents Carla giving 1/4 of the stamps to Thomas.
Multiply this number by 2. This represents Jim giving half of the stamps to Carla.
Multiply this number by 2. This represents John giving half of his stamps to Jim.
John started out with 64 stamps.

Answer:
Tangent at (1,2) has value . And (-2, 4) is the point of intersection of horizontal tangent.
Step-by-step explanation:
Given curve equation,
To find tangent at (x,y)=(1,2) and point of intersection of horizontal tangent, differentiate (1) withrespect to x we get,
At (1, 2), tangent line is,
To find point of intersection of horizontal tangent we have to do,
Thus,
At x=0, y=0
but snce,
at (0,0) there exist a vertical tangent. And,
At x=-2, y=4.
Thus (-2, 4) is the point of intersection of horizontal tangent.
The answer is:
1- A line of symmetry will connect a vertex and a midpoint of an opposite side.
2- It has -fold symmetry.
The explanation for this answer is shown below:
1- By definition, a line of symmetry is an imaginary line that divides a figure into two equal images or equal halves. If you connect a vertex and a midpoint of an opposite side of an heptagon by drawing a line, you will obtain two equal halves.
2- An heptagon has seven vertices, therefore, based on the information mentioned above, it has -fold symmetry.
