Answer:
The mid-point of the given line segment is:(5.5,-6.5)
Step-by-step explanation:
let us consider two points A and B with coordinates (a,b) and (c,d) respectively.
let C be the mid point of A and B then then the coordinates of C is given by 
.
in the given question (a,b)=(9,-8) and (c,d)=(2,-5) so the mid point of these two points are 
=(5.5,-6.5)
Hence, the coordinates of the midpoint of the line segment with endpoints B(9,-8) and C(2,-5) is (5.5,-6.5).
Answer: 90 degrees, 43 minutes, 16 seconds
Step-by-step explanation: To convert from decimal degrees to degrees minutes and seconds, the whole number part which is 90 is the degree, then multiplying the decimal part (0.721) by 60 gives the minutes which is 43 and finally multiplying the remaining decimal (0.26) by 60 gives the seconds which is approximately equal to 16
I believe the answer is B for this question
Dy/dx = dy/dt * dt/dx
xy = 4
y + x(dy/dx) = 0 by implicit differentiation.
x(dy/dx) = -y
dy/dx = -y/x
<span>dy/dx = dy/dt * dt/dx dy/dt = -2
</span>
<span>-y/x = -2 * dt/dx
</span>
y/(2x) = dt/dx
dt/dx = y/(2x)
dx/dt = 2x/y
When x = -3, xy = 4, y = 4/x = 4/-3 = -4/3
dx/dt = 2*-3/(-4/3) = -6 *-3/4 = 18/4 = 9/2 = 4.5
dx/dt = 4.5
