Answer:

Option (C)

Step-by-step explanation:

By the definition of a major arc - any arc of a circle which measures more than 180° is the major arc.

In the given circle, AC and BD are the two chords.

And arcs measuring more than 180° are,

$(\widehat{BCA}, \widehat{CDB}, \widehat{ABD},\widehat{DAC},\widehat{DBC},\widehat{ACD})$

Therefore, the arcs given in Option (C) will be the major arcs of the circle O.

Option (C) will be the correct option.

What is the explicit formula for this sequence -7, -4, -1, 2, 5

Nataliya [291]

Answer:

$\large\boxed{a_n=3n-10}$

Step-by-step explanation:

It's an arithmetic sequence.

$-4-(-7)=-4+7=3\\-1-(-4)=-1+4=3\\2-(-1)=2+1=3\\5-2=3$

The difference is constant.

The explicit formula of an arithmetic sequence:

$a_n=a_1+(n-1)d$

Substitute:

$a_1=-7,\ d=3$

$a_n=-7+(n-1)(3)$ <em>use distributive property</em>

$a_n=-7+3n-3\\\\a_n=3n+(-7-3)\\\\a_n=3n-10$

Construct a truth table for the logical operator NOR.

Rasek [7]

Answer:

A B A NOR B

F F T

F T F

T F F

T T F

Step-by-step explanation:

The logical operator NOR produces a result that is the negation of the logical operator OR.

The truth table for the logical operator NOR can be obtained by the negation of the results of the truth table for the logical operator OR.

Let A and B be the the logical values (or inputs). The operator OR produces a value of true if and only if at least one operand is true. The truth table for OR is:

A B A OR B

F F F

F T T

T F T

T T T

So, the truth table for NOR is:

A B A NOR B

F F T

F T F

T F F

T T F

Notice that the negation of OR (which is NOR) is obtained by changing the F by T and the T by F in the column of the results.

This table can also be writen with 0 instead of False and 1 instead of True.

58 yd<br> 73 yd<br> Use 3.14 Instead Of Pie Symbol

defon

Answer:

$771096.8 \: yd^{3}$

Step-by-step explanation:

If you are trying to find the volume, you would use the formula:

$\pi \: r ^{2} (h)$

You would plug in the radius (r), which is 58, and then plug in the height, which is 73.

Make sure you remember to use 3.14 and not the pi key if you are using a calculator.

The final answer is 771,096.8 yd^3

Kasey has three pieces of wood that measure 9 inches, 12 inches, and 21 inches. Can she make a right triangle

Harrizon [31]

Answer: No

Step-by-step explanation:

Add 2 sides together. If the sum of greater than the length of the 3rd side for all 3 options it can form a right triangle if it doesn’t than it can’t:

9 + 12 = 21 which is not greater than the 3rd side length of 21 so this cannot form a right triangle.
