J/9=5
Multiply both sides by 9
Which gets you
j = 45
Answer:
dV/dt = 0,474552 in³/units of time
dV/dt = 0,47 in³/units of time
Step-by-step explanation:
Volume for the right circular cone:
V(c) = (1/3)*π*x²*h
Where x is radius of the circular base, and h the heigt
Differentiating on both sides of the equation, keeping in mind that h is constant, we get:
dV/dt = (1/3)*3,6*2*x*dx/dt (1)
Now when radius changes from 1,3 to 1,27 inches or 0,03 in in/units of time
dV/dt = (1/3)*3,6* 2*(1,3)²*dx/dt
units h in inches
radius in inches
dx/dt in inches/units of time
Then
dV/dt = 0,474552 in³/units of time
dV/dt = 0,47 in³/units of time

Answer:
g=x+2
Step-by-step explanation:
Let's solve for g.
gx=x2+2x
Step 1: Divide both sides by x.
gx/x = x2 +2x / x
<u>g=x+2</u>

Step-by-step explanation:
as the graphic shows, we are dealing with a special rhombus : a square.
this is proven by the fact that the angle on one side of the diagonal at the corner is 45°. so, the other side must be 45° too, and so we have 90° angles at the corners.
what is not clear to me is : what is 6 cm long ? a half-diameter, or the whole diameter ?
I assume the half-diameter.
what the graphic is trying to suggest is that we have 4 little right-angled triangles that are also isoceles triangles (their legs are equally long).
every leg is 6 cm long (based on my assumption above).
because they are right-angled, the area of each of these little triangles is leg×leg/2
6×6/2 = 18 cm²
we have 4 triangles, so the total area is
4×18 = 72 cm²
if 6 cm stands for the whole diagonal after all, then the only change is the length of the legs, which would be then 6/2 = 3 cm.
then we would have
3×3/2 = 4.5 cm² for a single triangle
and
4×4.5 = 18 cm² for the whole area.
