your friend want to know the amont of salt added to her favorite fast food french fries what would you recommend that she do to
Alexeev081 [22]
That nutritional information is usually not posted up on the wall,
but by federal law, it's available on request, to any customer, at
any fast-food place. 

All she has to do is ask to see the manager, and then ask the
manager for the nutritional information booklet. 

She'll get a nice printed booklet that tells the salt content in the
fries, AND the amount of many other substances in ALL the items
sold at that place.

It's the law.  Don't be bashful.

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 137 ft at an angle of 31.0° abov
Zielflug [23.3K]

Answer:

Explanation:

We know that

Δr = r₁ - r₀

r₀ = 0 i + 0 j

r₁ = (162+137*Cos(31º)+137*Cos(-48º)) i + (0+137*Sin(31º)+137*Sin(-48º)) j = (371.1028 i - 31.2506 j) ft

Δr = r₁ - r₀ = (371.1028 i - 31.2506 j) - (0 i + 0 j) = (371.1028 i - 31.2506 j) ft

Magnitude:

Δr = √((371.1028)²+(-31.2506)²) = 372.4163 ft

Angle:

tan θ = (- 31.2506 / 371.1028) = -0.0839   ⇒   θ = tan⁻¹(-0.0839) = - 4.8135º

(below the horizontal).

PLEASE HELP!! WILL REWARD!!
Fudgin [204]

velocity = \frac{displacement}{time}

Displacement measures how far it is from the starting point and the final location, which in this case is the distance between Honolulu and Los Angeles. The difference between distance and displacement is that distance measures how far the object actually travels. For example, the airplane may not fly in a straight line and it may have detours, making the distance much greater than the displacement.

On the other hand, the plane could fly at different speeds at different periods of time. It will be so much more complicated if we have to calculate it. That's why this question only asks you to calculate the average velocity of the plane, ie. \frac{total displacement}{total time}

So, we have

the required average velocity = \frac{2558}{5}

= 511.6 miles/hour

Hope this helps!
