A polygon has vertices at (4, 1), (4,7), (10, 7) and (10, 1). How does the perimeter of
the polygon change if each coordinate is multiplied by 3?

Answers

Answer: The perimeter triples

The perimeter goes from 24 to 72

24*3 = 72

==========================================================

Explanation:

I recommend plotting the four points on the same xy grid system. Connect the points with segments to form a rectangle. This rectangle is also a square. You should find that each side of the square is 6 units long, so the perimeter is 4*6 = 24 units.

If we multiply each coordinate by 3, then that will make each side length 3 times longer than before. That means each side is now 6*3 = 18 units long. The perimeter is 4*18 = 72 units.

Note how the jump from 24 to 72 is "times 3". Therefore, the scale factor of 3 will make the new perimeter 3 times longer compared to the old perimeter.

assume f is a one to one function of f(x)= 4-6x find f^-1(-32)​

Answers

Answer:

f^-1(-32)=6

Step-by-step explanation:

Find the inverse of the function f(x)=4-6x:

f(x)=4-6x

y=4-6x

x=4-6y

x-4=-6y

(x-4)/-6=y

-1/6x+2/3=y

y=-1/6x+2/3

f^-1(x)=-1/6x+2/3

Plug in f^-1(-32) for f^-1(x) and simplify:

f^-1(-32)=-1/6(-32)+2/3

f^-1(-32)=16/3+2/3

f^-1(-32)=18/3

f^-1(-32)=6

I need help ASAP please

Answers

Answer:

True, false, true

Step-by-step explanation:

Because the minimum value of f(x) is -1, and the minimum value of g(x) us -25. It comes only once.

Roots are the points on the x - axis or when the x is 0. The roots of f(x) are positive.

f(0) means when x is 0, so f(0) = 3 or 5, and g(0) = -24

f(-2) means that for every x given in the equation, -2 would be substituted in it's place. Therefore;

Two geometry questions in the attached photos - If I have a line, do I have a plane? & If I have three points, do I always have a plane?

Answers

Answer:

18) A: only if you have an additional point not on the line.

19) D: No, because all the points may be on the same line.

Step-by-step explanation:

There are basically 4 ways we can determine a plane and they are;

- When we have three non - collinear points: What this means is that if we have three points that are not on one line, then it means that only one particular plane can pass through those points.

- When we have a line and a point that's not on the line

- When we have two lines that intersect each other.

- When we have two lines that are parallel to each other.

From the four conditions above, we can now answer the question;

18) You can only have a plane if there is an additional point not on the line.

Option A

19) Having just three points may not always be sufficient to have a plane because it's possible that the three points may be on the same line which is not a condition for a plane. Thus, option D is correct.
