Answer:

Place the point of the compass on point M and draw an arc, making sure the width of the compass opening is greater than 1/2 MN.

Step-by-step explanation:

Ashton is constructing the bisector of MN¯¯¯¯¯¯¯

The first step will be :

Place the point of the compass on point M and draw an arc, making sure the width of the compass opening is greater than 1/2 MN.

He will make 2 arcs from M, one above the line and one below the line.

Then he will repeat the same with N and draw two arcs above and below the line.

Lastly he will draw a line passing through both the arcs(where both arcs cross).

This line is the bisector.

Question says that "Ashton is constructing the bisector of MN¯¯¯¯¯¯¯."

Now we need find about what should Ashton do for his first step?.


We know that to bisect any line say MN, we need to draw two arc from each end point M and N. Both arcs will intersect only when the width of the compass is more than half of the length of side MN. so that we we can join both intersection points to draw the perpendicular bisector.

Hence correct matching choice is C.

So the final answer is "C. Place the point of the compass on point M and draw an arc, making sure the width of the compass opening is greater than 12MN."

Kisachek [45]

Answer:

13

Step-by-step explanation:

Using Pythagoras Theorem:

a^2+b^2=c^2

Substitute values of a and b:

5^2+12^2=25+144=169

c^2=169\\c=13

The length of the missing side is 13.

The temperature is -3 F at 7:00 am During the next 4 hours the temperature increases 21 F. What is the temperature at 11:00am ?
telo118 [61]
Now what you want to do is 21 + (-3). Since this is the same as saying 21 - 3, the answer is 18. Therefore, the answer is 18°F.

Write the name of the period that has the digits 486
kogti [31]
1.       <span>The name of period that has 486 in the given number which is 751 486  is hundreds.
period is considered to a group of places of the digits, like the given number 486 is the group of hundred because the highest number it contains is 400.
=> 400 + 80 + 6
=> 4 hundreds + 8 tens + 6 ones
=> 486
while 751 is the period of hundred thousands.
=> 700 000 + 50 000 + 1 000
=> 751 000

(7a^3 -2a-2)+(-5a+3)
atroni [7]

Answer:

7a  3  −7a+1

Step-by-step explanation: I hope this help.

STEP

1

:

Equation at the end of step 1

 ((7a3 -  2a) -  2) +  (3 - 5a)

STEP

2

:

Polynomial Roots Calculator :

2.1    Find roots (zeroes) of :       F(a) = 7a3-7a+1

Polynomial Roots Calculator is a set of methods aimed at finding values of  a  for which   F(a)=0  

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  a  which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient

In this case, the Leading Coefficient is  7  and the Trailing Constant is  1.

The factor(s) are:

of the Leading Coefficient :  1,7

of the Trailing Constant :  1

Let us test ....

  P    Q    P/Q    F(P/Q)     Divisor

     -1       1        -1.00        1.00      

     -1       7        -0.14        1.98      

     1       1        1.00        1.00      

     1       7        0.14        0.02      

Polynomial Roots Calculator found no rational roots

Final result :

 7a3 - 7a + 1
