Answer:
Point C
Step-by-step explanation:
At point C, the graph is changing from decreasing to increasing.
The answer is B. They did not multiply the constant 2 by 4 when multiplying through to remove the fraction. so the correct answer would be x-4y=-8
Answer:
Supriya found the Perimeter of the bedroom.
Step-by-step explanation:
Supriya plans to hang the string of twinkle lights all the way around her walls. This is equivalent to making a boundary around the walls using the twinkle lights.
In geometry the boundary of a figure refers to its Perimeter. So, this means the measurement which Supriya found was the Perimeter of her room. Perimeter is defined as the sum of all the sides of a figure. Room is a 4-sided figure i.e. a quadrilateral, and most likely it will be in shape of a rectangle. Perimeter of a rectangle is calculated as:
Perimeter = 2 ( Length + Width )
So, the perimeter of Supriya's bedroom is 36 meters.
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
