Answer:

0.22

Step-by-step explanation:

So in this problem, we have to find the hypotenuse first, since sine is opposite over hypotenuse.

We can do this using the pythagorean theorem (you can search it if you don't know). Or, we can just remember this as one of our pythagorean triplets (9,40,41). The last side will be 41.

We have to find the value of sin(D)

opposite/hypotenuse = 9/41 = 0.2195 which is about 0.22

kompoz [17]

The exponential equation (in thousands) is:
$V = 28 e^{-rt}$
plug in t=3 yrs, and solve for 'r'.
$14 = 28 e^{-3r} \\ \\ \frac{1}{2} = e^{-3r} \\ \\ ln(\frac{1}{2}) = -3r \\ \\ r = \frac{ln(\frac{1}{2})}{-3} = 0.231 = 23.1%$

Find value of car when t = 10
$V = 28e^{-2.31} = 2.779$

Answer:

Step-by-step explanation:

(a). B, C and D are the distinct points that are collinear.

(b). FC and BD are the distinct lines that intersect each other at a point C.

(c). E, F, C and A are the points that are coplanar (on the same plane).

(d). Another name for plane X is plane AEF. (Since a plane is defined by the three distinct points on the same plane.

Answer:

Step-by-step explanation:

you could wright the equation like 15/100=4.20/x

All I did is 100 divided by 15, which is 6.6666667, and then multiply that number by 4.20.

<span>Let,
diameter = segment AB through center P.
Set the compass to the radius PB, at B and draw two little arcs that intersect the circumference of the circle at C and D.
Then Triangle ACD will be an equilateral triangle inscribed in the given circle.
Hence,
The right option is :
