I rlly rlly rlly need help! Complete the following proof. Given: Points R, S, T, Q on circle O Prove: m\overarc RS + m\overarc S

harina [27]

Answer:

$m(\widehat {RS})+m(\widehat{ST})+m(\widehat{TQ}) + m(major\ arc RQ) = 360\ degree$

Step-by-step explanation:

As we can see in the figure that

The R, S, T ,and Q are the points on the circle O.

Also

The measurement of the circular arc is equivalent to the measurement of the angle at the center of the arc

So by this

$m(\widehat{RS})=m(\angle ROS)$

$m(\widehat{ST})=m(\angle SOT)$

$m(\widehat{TQ})=m(\angle TOQ)$

m(major arc RQ) = m(∠QOR)

So,

$m(\widehat {RS})+m(\widehat{ST})+m(\widehat{TQ}) + m(major\ arc RQ) = m(\angle ROS)+m(\angle SOT)+m(\angle TOQ)+m(\angle QOR)$

And as we know that

All angles sum = 360°

Therefore

$m(\widehat {RS})+m(\widehat{ST})+m(\widehat{TQ}) + m(major\ arc RQ) = 360\ degree$

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as ed

VikaD [51]

Answer:

Break-even point in units= 4,400

Step-by-step explanation:

Giving the following information:

Fixed costs= $49,500

Unitary variable cost= $12

Selling price= $23.25

<u>We need to calculate the level of sales that will result in a net profit of zero. We need to use the break-even formula:</u>

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 49,500 / (23.25 - 12)

Break-even point in units= 4,400
