cos(b) = ?

Sin(a) = ?cos(b) = ?

Answers

Answer 1
sina= 9/15 = 3/5
cosb= 9/15 = 3/5
Answer 2

Answer:

sina = cosb = [tex]\frac{3}{5}[/tex]

Step-by-step explanation:

sina = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{9}{15}[/tex] = [tex]\frac{3}{5}[/tex]

cosb = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{9}{15}[/tex] = [tex]\frac{3}{5}[/tex]

How many people will there be if I have 58 friends and each of them bring five friends, but 6 of my friends are couples? So, how many people will be at my party, including me?

Answers

Answer:

276 individuals at the party.

Step-by-step explanation:

If 6 of your friends are couples then we would count them as 1 each and it would be 3 friends. Therefore we subtract 3 from your 58 friends.

58 - 3 = 55 friends

Each of them brings 5 friends so we multiply your number of friends by 5.

55 * 5 = 275 friends

Finally, we add you because you are included

275 + 1 = 276

There will be a total of 276 individuals at the party.

A.) $1137.93
B.) $1274.88
C.) $1078.44
D.) $5780.00

Answers

Answer:

A

Step-by-step explanation:

If it loses 15% of its value every year, then each subsequent year will be worth 85% of the previous year. If we think of this as a geometric series, then the worth would be 8000(.85^t) where t is years after the first year. If you plug in 12, then it's 1137.93.

XY bisects ∠AXB. If m∠AXB = -18x° and m∠AXY = (3x2 - 12)°. Find m∠BXY. Please help, I'm blanking!!!

Answers

Answer:

m<BXY = 36degrees

Step-by-step explanation:

If XY bisects ∠AXB, then;

<AXY + <BXY = <AXB

Given

m∠AXY = (3x^2 - 12)°

m∠AXB = -18x°

Required

Find m∠BXY.

From the formula above;

Find m∠BXY = <AXB - <AXY

m<BXY = -18x - (3x^2-12)

m<BXY = -18x - 3x^2 + 12

m<BXY =  -3x^2 -18x + 12

Also <AXY = m<BXY

3x^2 - 12 =   -3x^2 -18x + 12

6x^2 + 18x -24 = 0

x^2+3x-4 = 0

Factorize

x = -3±√9+16/2

x = -3±5/2

x = -3+5/2 and -3-5/2

x = 2/2 and -8/2

x = 1 and -4

Substitute x = 1 into m<BXY

m<BXY =  -3x^2 -18x + 12

m<BXY =  -3(1)^2 -18(1) + 12

m<BXY =  -3 -18+ 12

m<BXY =  -9

when x= -4

m<BXY =  -3(-4)^2 -18(-4) + 12

m<BXY =  -3(16) +72+ 12

m<BXY =  -48+84

m<BXY = 36degrees

A container contains 3 yellow, 2 orange, and 4 pink roses. Without looking, if James chooses a rose from the container, what is the probability that James will select an orange rose?

Answers

Answer:

Orange rose = 2/9

Step-by-step explanation:

In order to find probability of picking one item, you add all the possible things you could choose. So, 3+2+4 equals a total of 9 outcomes, and that would be your denominator for your fraction of probability. From there it's really easy. Just put the amount of things your trying to find the probability for in the numerator spot.

Ex.

There are 9 total roses so that would be the denominator (?/9)

To find out the probability for picking an orange rose, you'd put the 2 in as the numerator because that is the total number of orange roses you have (2/?)

Then just put the two together (2/9).
