X²-4x+18=0

x= 4 ± √(16-4*1*18) / 2

x=4±√(16-72) /2

x= 4 ± √-56 /2

x = 4±2i√14 / 2

x= 2±√14 * i

Let b and p represent the distances traveled by baby and pickles, respectively.
.. b +p = 27
.. p = 5(3b -1)

Substituting, you have
.. b +5(3b -1) - 27
.. 16b -5 = 27
.. 16 b = 32
.. b = 2

The baby travel was 2 miles.
The pickles travel was 25 miles.

When constructing a perpendicular bisector why must the compass opening be greater than 1/2.
muminat

It is critical to open a compass with over half the way in order for the arcs formed to meet for perpendicular bisector.

<h3>What is perpendicular bisector?</h3>

A perpendicular bisector would be a line that cuts a line segment in half and forms a 90-degree angle at the intersection point. In other words, a perpendicular bisector separates a line segment now at midpoint, forming a 90-degree angle.

Now, consider an example;

When you wish to build a perpendicular line on a line segment, like line AB, you do the following;

  1. Set the compass on a radius more than half the length of the line AB.
  2. Using A as your center, draw an arc above and below line AB.
  3. With the same radius and B as our center, draw additional arcs on top or below line AB to join a first arcs on the both side of the line.
  4. Join the two arc intersections to cut line AB at M.

A line AB appears to be bisected perpendicularly as a result. The arcs would not have met if the compass is opened less than half way down line AB.

Seven integers, x1, x2, x3, x4, x5, x6, and x7, are picked at random from the set of all integers between 10 and 110, inclusive.
Ronch [10]

Answer:

0+1+2+3+4+5+6=21

Step-by-step explanation:

Since integers are given as x1, x2, x3, x4, x5, x6, and x7. This means they are consecutive integers divisible by 7.

Thus no matter which 7 consecutive integers are these, their reminders will always be in the order of 0,1,2,3,4,5 & 6.

So their sum  will be 0+1+2+3+4+5+6=21.
