Suppose that for all t, a particle moving with constant speed is parameterized by r(t). Given that the length of the path from t

= 5 to t = 7 is equal to 8, find the value of the speed, llv(t)ll.

Answer: value of the speed, llv(t)ll = 4.0

Step-by-step explanation:

Given;

time interval t1 =5, t2= 7

Length of path ( distance) L = 8

Speed = distance travelled/ time taken

Speed = dL/dt

Speed = 8/(t2-t1) = 8/(7-5)

Speed = 8/2

Speed = 4.0

Since it's moving at constant speed the speed = 4.0

Write an equation in slope intercept form for a line with a slope of - 3/2 that passes through the point 4,10 help please
Archy [21]

Answer:

y =  \frac{ - 3}{2} x + 16

Step-by-step explanation:

They give us the slope so this makes it a lot easier.

Slope intercept formula is

y=mx+b

(m) is slope

(b) is y intercept

we can apply our slope into the formula

y=-3/2x+b

Now we can replace (y) with the (y) from the ordered pair they gave us (4, 10), and replace the (x) with the (x) from the ordered pair they gave us

(4, 10)

10=-3/2(4)+b

Now solve

10=-6+b

Add 6 to each side

16=b

Now we we put both our slope and intercept into the formula.

y =  \frac{ - 3}{2} x + 16

A rectangular window is topped with a semicircle on top. the height of the rectangular part is 1 more than 3 times its width , w
tensa zangetsu [6.8K]

In general for a rectangle of dimensions w by h and a semicircle of diameter w we get an area:


A = wh + \frac 1 2 \pi (\frac w 2)^2


The halfs are because a semicircle is half a circle and a radius is half a diameter.


We're told


h = 1+ 3w


Substituting,


A(w) = w(1+3w) + \frac 1 2 \pi (\frac w 2)^2


Answer: B
