A student is skateboarding down a ramp that is 5.5 m long and inclined at 19° with respect to the horizontal. The initial speed of the skateboarder at the top of the ramp is 2.9 m/s. Neglect friction and find the speed at the bottom of the ramp.

The alarm at a fire station rings and a 87-kg fireman, starting from rest, slides down a pole to the floor below (a distance of 3.9 m). Just before landing, his speed is 1.3 m/s. What is the magnitude of the kinetic frictional force exerted on the fireman...

Calculate the perimeter of the triangle formed by the middle points of the sides of the triangle formed by points A(-8,6) B (2,5) and C (1,7) I've already got the distance between all the points given but I do not know what to do next. Can you help me?

how does one go about solving something such as: conjugate(z+2-3i) = z+5+10i Conjugates of actual complex numbers are very simple, but the inclusion of z trips me up

Suppose that the sequence x0, x1, x2... is defined by x0 = 1, x1 = 4, and xk+2 = −6xk+1−8xk for k≥0. Find a general formula for xk. Be sure to include parentheses where necessary, e.g. to distinguish 1/(2k) from 1/2k. . No idea how to go about this, pleas...

A calorimeter of heat capacity 48 JK-1 containing water at 20oC. A 200W electric heater is used to raise the water to boiling point of 100oC in 4 minutes; it is found that after a further 6 minutes, 0.03 kg of water has been evaporated. Calculate (i) The...

i still cannot solve the problem. can someone please explain it a little bit more?

Briana, Dakota, Kirby will not, no one

Well, if the triangle formed is of type rectancgle, then what you need to use is Pythagorean theorem. The hypotenuse is 122 inches and one of the cathetus is 120 inches. You clear the other cathetus in the equation and that's it.

I suggest you to do a diagram to guide yourself. Draw a line and let the points at the end to be Phoebe and Tucker locations. Then with help of a protactor, draw the line whether the angle is formed. Check by yourself who is closer, or try it on real life...

I know Spanish very well, so let me see if I can help you. We can replace the buys flower for someone to "le" Juan le compra Then we complete it but replacing the femenine noun of grandmother with "a ella" Juan le compra flores a ella. I think that is lik...

If I may ask a follow up question: everything makes perfect sense up until the last line. How exactly did you come up with -3 and 4? I've been trying to solve similar problems and the coefficient seems the only thing off

nevermind, the pdf shows it very clearly

Well researching the need should have already been done so prolly dat.
