Mathematics

Step-by-step explanation:

x^2 + y^2 = r^2 --> r =\sqrt{(-4)^2 + 5^2} =\sqrt{41}

cos = x /r = -4 /\sqrt{41}

sin = y /r = 5/\sqrt{41}

tan = sin /cos = -5 /4

Carrie is buying bulk candy for a high school fundraiser. She buys 1000 candy bars for $350. What is the unit cost per candy bar
liubo4ka [24]
1000 candy bars ... $350
1 candy bar ... $x = ?

If you would like to know what is the unit cost per candy bar, you can calculate this using the following steps:

1000 * x = 350 * 1
1000 * x = 350    /1000
x = 350 / 1000
x = $0.35

Result: She can buy 1 candy bar for $0.35, so the correct result would be B) $.35.

Im confusedd, please help??
spayn [35]

Answer:  three sets of value show 3 consecutive increases and they could be the intensities during fourth, fifth, and six visits:

  • 66%, 69%, 72%;
  • 63%, 65%, 67%, and
  • 67%, 72%, 77%

Explanation:


1) The program recommends a constant intensity for 3 visits, which is what the table shows:

Day        Intensisty

1             63%

2            equal ⇒ 63%

3            equal ⇒ 63%


2) Hence, you have to determine the valid sets that meet the recommendation for the fourth, fifth, and six visits, which are the next three.


2) For the next three visits, the program recommensd increasing intensities.


There are three options that show 3 consecutive increases; they are:

  • 66%, 69%, 72%;
  • 63%, 65%, 67%, and
  • 67%, 72%, 77%

Therefore, those are the choices that apply.
