Julia has determined that CE is perpendicular bisector of AB. The next step of a valid proof would be: <em>B. AC = BC based on the </em><em>perpendicular bisector theorem</em>.

<h3>What is the Perpendicular Bisector Theorem?</h3>

The perpendicular bisector theorem states that if a point is located on a segment (perpendicular bisector) that divides another segment into two halves, then it is equidistant from the two endpoints of the segment that is divided.

Thus, since Julia has determined that CE is perpendicular bisector of AB, therefore the next step of a valid proof would be: <em>B. AC = BC based on the </em><em>perpendicular bisector theorem</em>.

Last month McKinneys Apothecary dispense the following liquid medication 1 gallon 3 quarts 7 pints and 3 dozens 6ounces of bottl
seraphim [82]

Answer: 10204 millimeters

Step-by-step explanation: A gallon = 3875 mm. A quart is 946. 946x 3 = 2838. A pint is around 473 mm which, when multiplied by 7, is 3311. Finally, there are 6 ounces which are approximately 30 mm. 6x30 = 180. We add all of this up : 3875 + 2838+ 3311 + 180 = 10204.

Which equation could generate the curve in the graph below
Setler79 [48]
The curve has been attached and the answer choices are:

y = 3x² – 2x + 1

y = 3x² – 6x + 3

y = 3x²<span> – 7x + 1
</span>
The attached graph has a vertex in the first quadrant. Therefore, the coordinates of the vertex would be both positive.

Let's start with first equation:

                                               y = 3x² – 2x + 1

using the equation of axis:
                                            x = -b/2a
                                            x = 2/6
                                            x = 1/3
SUbstituting the value of x in the main equation to get the y-coordinate of the vertex.
                                               y = 3(1/3)² – 2(1/3) + 1
                                               y = 3/9 – 2/3 + 1
                                               y = 1/3 – 2/3 + 1
                                               y = (1 - 2 + 3)/3
                                               y = 2/3

Hence, the vertex would be:
                                             (h,k) = (1/3 , 2/3)

Also, the leading coefficient is positive, so the parabola would be concave up.

Thus the final answer choice will be:

                                             y = 3x² – 2x + 1

Help on these two problems please
charle [14.2K]
14) Note that Carlos travels 12 miles from school to home (and vice versa). Note also that it is only asking for "to school", and for 5 days.

Multiply 5 with 12

12 x 5 = 60

60 miles is your answer.
-------------------------------------------------------------------------------------------------------
15) Note:

Mandy travels 9 trips, and each trip is 10 miles
Matt travels 11 trips, and each trip is 8 miles.

Multiply each number to corresponding.

Mandy = 9 x 10
Mandy = 90

Matt = 11 x 8
Matt = 88

Mandy travels more miles than Matt by 2 miles
