From the question "The position of a particle s(t)= 3sin1/2t+1. So what is the average velocity of the particle for [0,3pi/2]?"

The equation is
s(t) = [3 sin 1] / [2t + 1]

given [0, 3pi/2] then, we can substitute it to the equation
where t = 0
and s(t) = 3pi/2

s(t) = [3 sin 1] / [2t + 1]
s(t) = [3 sin 1] / [2(0) + 1]
s(t) = [3 sin 1] / 3
s(t) = sin 1

So the correct answer is s(t) = sin 1

The weight of water is 62 and one half lb per cubic foot. How many cubic feet would be occupied by 180 lb of​ water?
inessss [21]

<u>Answer:</u>

2\frac{22}{25} cubic feet

<u>Step-by-step explanation:</u>

We are given that the weight of water is 62 and one half lb per cubic foot and we are to find the number of cubic feet that would be occupied by 180 lb of water.

For that, we will divide total amount of water by per unit weight of water:

Cubic feet occupied by 180 lb of water = \frac{180}{62.5} = = 2.88 cubic feet or 2\frac{22}{25} cubic feet

Find a ⋅ b. a = &lt;5, 2&gt;, b = &lt;4, 5&gt;
cestrela7 [59]

Answer:

  30

Step-by-step explanation:

For a = <xa, ya> and b = <xb, yb>, the dot product is the sum of products ...

  a·b = (xa)(xb) + (ya)(yb)

Substituting the given information, you have ...

  a·b = 5·4 + 2·5 = 20 + 10

  a·b = 30

_____

Some graphing calculators can do such math. There are also dot product calculators available on the Internet. If you have quite a few of these to calculate, you can put the appropriate formula into a spreadsheet.

What two numbers multiplies to 36 and add to negative 21
anastassius [24]
Factor 36 and add them, make sure both are negatie
1+36=37, nope
2+18=20 nope
3+12=15,nope
4+9=13, nope
6+6=12, nope

the closest one is 20

I hope you meant adds to -20, because if you did, then answer is -2 and -18

if you did mean 36 and adds to -21, then the numbers are \frac{-21-3 \sqrt{33} }{2} and \frac{-21+3 \sqrt{33} }{2}, aprox -19.1168 and  -1.8831

What is the slope of a line that is parallel to the line represented by the equation x-y=8
coldgirl [10]
The slope of x-y=8 is 1 because it's actually y = x-8

Parallel means the slope is equal to 1 as well.
