Answer:
1.333 yards
Step-by-step explanation:
let the yards for each fabric be x
6x=8
x=1.333
The distance between (3, 2) and (-3, -6) is 10 units
The correct answer is B) 10
Further explanation:
Given points are:
(x1,y1) = (3,2)
(x2,y2)=(-3,-6)
The distance formula is given by:
Putting the values
The distance between (3, 2) and (-3, -6) is 10 units

Answer:
0.51cm/s
Step-by-step explanation:
Area of a circle A = πr²
r is the radius
Rate of change of area is expressed as;
dA/dt = dA/dr • dr/dt
dA/dr = 2πr
radius r = 77cm
dA/dt = 79cm²
Get dr/dt
Substitute the given values into the formula
79 = 2π(77)•dr/dt
79 = 154dr/dt
dr/dt = 79/154
dr/dt = 0.51cm/s
Hence the rate of change of the radius is 0.51cm/s
As a mixed number, that would be 4 2/4, or 4 1/2 simplified.
