Answer:
f(-1) = -1
Step-by-step explanation:
x = -1 falls in the middle segment, where -2 < x < 2. So, the applicable function definition is ...
f(x) = -2x -3
f(-1) = -2(-1) -3 = 2 -3
f(-1) = -1

Problem 5
A counterexample could be a number like 6. Divide it over 2 and we get 6/2 = 3, which is a whole number. This shows 6 is a multiple of 2. However, 6/4 = 1.5 is not a whole number, so 6 is not divisible by 4. The overall claim is false.
======================================================
Problem 6
Let's say we are subtracting a positive number and a negative number. For instance, let's say we're subtracting 10 and -7
So,
10 minus -7 = 10 - (-7) = 10+7 = 17
When subtracting a negative, the two minus signs cancel to form a plus sign. The result we get is 17, which is larger than the greater number 10. So this is one counterexample that proves the claim to be false.
======================================================
Problem 7
Start with a circle. The circle can be any size. Plot four random points on the circle. The points can be anywhere you want. Let's label those points A,B,C,D. Form quadrilateral ABCD.
Now let's say we pick point A and pull it off the circle and pull it outside the circle. Points B,C and D remain on the circle. This is one example where we cannot draw a circle through this new arrangement of points. The circle goes through B,C, and D just fine; however, it doesn't go through point A. If you try to attempt to get the circle to go through A, then you'll have to pick B,C or D to ignore. In other words, you'll only be able to pick three points that the circle can go through. Therefore, a circle cannot be drawn as described for every quadrilateral.
Note: Any quadrilateral that has all four points on the same circle is known as a cyclic quadrilateral.

A figure has been dilated from the origin by a scale factor of one seventh. if another dilation from the origin maps the dilated image back
onto the original figure, what is its scale factor?
Answers
Answer:
its scale factor is 3
Step-by-step explanation:
plz mark brainliest
To map the dilated image back onto the original figure, the scale factor needed is 7.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Dilation is the increase or decrease in the size of a figure by a factor.
If a figure is dilated from the origin by a scale factor of one seventh, it is given by:
(x, y) ⇒ [(1/7)x, (1/7)y]
To map the dilated image back onto the original figure, the scale factor needed is 7. Hence:
[(1/7)x, (1/7)y] ⇒ (x, y)

Answer:
1.) 5 2.) 10.58
Step-by-step explanation:
For each one, you use the equation a^2 + b^2 = c^2 where c is the "hypotenuse"-- the side of the triangle opposite (facing) the right angle which is shown with a small box. The variables a and b do not matter, as long as they are the "legs", the other 2 sides.
So it is 4^2 + 3^2 = c^2 which simplifies to 16+9=25=c^2 and square root both sides and you get c=5
and 12^2 + b^2 = 16^2 which simplifies to 144+ b^2 = 256 and subtract 144 from both sides and you get b^2 = 112 and square root both sides and it is approximately 10.6 :)

The graph of f has inflection points when x = 0 and -1.
Given that,
If graph = f"(x) = x(x + 1)(x - 2)^2
We have to determine,
The graph of f has inflection point when x is.
According to the question,
Inflection point is the point in which the rate of slope changes in increasing to decreasing order or vice versa.
These points are generally not local maxima or minima but stationary points.
[tex]f''(x) = 0[/tex]
Therefore,
The graph of f has inflection point at,
[tex]f''(x) = x (x+1) (x-2)^{2} = 0\\\\x = 0 \ and \ x+1 = 0 \ \ = x = -1\\\\ or \ x-2 = 0 , \\\ \ \ = x =2[/tex]
On taking intersection of these points,
The graph has inflection points at x = 0 and -1.
Hence, The graph of f has inflection points when x = 0 and -1.
