Some bank loans $250,000 for a yacht. The note will be repaid in equal monthly payments over 30 years with an interest at 12 percent.

How much of the first months payment an interest expense if the monthly payment was $2,571.53?

I have tried every combination I can think of and none of the answers are correct.

If you answer, please explain. Thank you.

I am looking through my old exams to prep for my final and I am stuck on this one.

Two forces act on a hockey puck. One is 23.3 N, directly eastward. The other is 15.0 N, 60.0° north of east. If you wish to apply a third force to keep the puck from accelerating, what must be its magnitude and direction?

I know the answer is [33.4 N, 22.9° south of west] but I struggled with this part before and am lost again.

If you could throw me a bone, i'd appreciate it. Thanks!

I am getting really frustrated with this problem.... I am already late on the submission so it doesn't matter but I want to know how to do the ****ing thing.

a = .01, n = 38, x
bar = 34, s2 = 12

what is the 95% CI for mu?

I need to know how to do it, and the answer please.. so I know if I am doing it right.

Three forces act on a body which moves with constant velocity. One force is 7 N acting at an angle of 45°, and the second is 18 N acting at an angle of 135°. What is the angle of the third force in degrees (measured the same way, relative to the positive x-axis, and between 0 and 360°) ?

Really stuck on this, any help would be appreciated, thanks!

Two people A and B are standing

A weighs twice as much as B.

If A pushes to the left on B, what can be said about the forces and accelerations on each person?

1. B experiences a force and an acceleration to the left, while A experiences an equal force in the opposite direction. A acceleration is to the right and is twice B.

2. B experiences a force and an acceleration to the left, while Fred experiences no force and no acceleration.

3. B experiences a force and an acceleration to the left, while A experiences an equal force and equal acceleration in the opposite direction.

4. B experiences a force and an acceleration to the left, while A experiences an equal force in the opposite direction. A's acceleration is to the right and is half of B.

5. Both A and B experience the same forces and accelerations.

I think it is number 4? Only have one shot at it though, thanks!

A box (mass m1 = 4.21 kg) on a frictionless plane inclined at angle θ1 = 31.1°

The box is connected via a cord of negligible mass to a box (mass m2 = 3.40 kg) on a frictionless plane inclined at angle θ2 = 58.9°.

The pulley is frictionless and has negligible mass. What is the tension in the cord?

I set it up as follows,

( (3.4 * 9.8 * sin(58.9)) + (4.21*9.8*sin(31.1)) ) / ( 1+ 3.4/4.21 )

I get... 27.5735 N

But am told that is wrong, anyone willing to point out where I messed up? Thanks.

There is a picture but it is just a right triangle lying on its hypotenuse with the boxes on either leg.

I ran into the following question and I am confused on what exactly they are asking for.

Kibitz Fitness received $27,000 from customers on August 1, 2011. These payments were advance payments of yearly membership dues.

At December 31, 2011, calculate what the balances in the Unearned Service Revenue and Service Revenue accounts will be. Round your answer to the nearest dollar.

They never say which year the dues are for so I assume they are for 2012, if that is the case then Kibitz should have 27k in unearned revenue at Dec 31st, 2011 right? I feel like they want me to divide the 27k over 5 months i'm not sure.

0 = 200 + 50*sin(61.2) - 4.9*t^2

4.9*t^2 = 200 + 50*sin(61.2)

t^2 = (200 + 50*sin(61.2)) / 4.9

t = sqrt((200 + 50*sin(61.2)) / 4.9)

t= 7.05

I am stuck on this problem, not sure which formula to use.

An object is throw into the air from an initial height of 200 m.

The object has an initial velocity of 50 m/s at an angel of 61.2 above horizontal.

How far away does the object land?

I am suppose to rhetorically analyze a website. My question is, what exactly does rhetorical analysis of a website consist of?

If you would explain it relatively basic terms I would appreciate it.

Thanks.

A vehicle accelerates from rest at 1.5 m/s2 for 15 seconds, the vehicle remains at this speed for an additional 20 seconds, after which the driver applies the breaks giving the vehicle an acceleration of -2.5 m/s2 until the vehicle is no longer moving.

How do I determine the total distance traveled?

Thanks!

a vehicle which is traveling at 120km/hr comes to a stop in 8 seconds after applying the brakes uniformly

How far does the vehicle travel in the 8 seconds?

I need a little help with this one, thanks

A plane comes to rest in 10 seconds after initially traveling 150 km/hr.

How far does the plane roll on the ground?

Any help with this would be appreciated, thanks.

Paid $18,500 cash for a parcel of land on which the business will eventually build an office building

How would this affect Assists, Liabilities, Contributed Capital, and Retained Earnings.

Thanks, struggling a little bit with this one.

Had a wrong value last time...

Have a mound shaped distributions that has a mean of 20, deviation of 5

What % of measurements will fall between -2 and +1 deviation?

I thought it was .819 but that is not correct..?

Thanks.

I am trying to find the degree of three vectors A+B+C

Vector coordinates are:

___|_X_|_Y_|

_A_| -6_| -3_|

_B_| -2_|_3_|

_C_|_4_|_6_|

I tried,

arctan(-3/-6) = 26.56

arctan(3/-2) = -56.31

arctan(6/4) = 56.31

Added them together to get 26.56 but that was incorrect.

If you know where I am going wrong with this feel free to let me know. Thanks

Standard normal random variable,

what is the probability that z = 0?

Not sure how to do Z when using =

thanks

The question I am working on is,

Vectors

___|_X_|_Y_|

_A_| -6_| -3_|

_B_| -2_|_3_|

_C_|_4_|_6_|

Find the magnitude of A + B + C.

I took

(-6^2 + -3^2) = 45, sqrt(45) = 6.7

(-2^2 + 3^2) = 13, sqrt(45) = 3.6

(4^2 + 6^2) = 52, sqrt(45) = 7.2

6.7 + 3.6 + 7.2 = 17.5

But the answer is not 17.5, where am I going wrong here? Thanks.

Trying to figure out the p-value for this problem,

Ho : p = .3

Ha : p > .3

T = 1.43

a = 0.05

Thanks!
