Answer:
Option B: 26cm is the radius of smaller circle.
Step-by-step explanation:
Given that:
Ratio of circumferences of two circles = 2:3
We know that circumference of circle is given by 2πr.
Radius of larger circle = 
= 39 cm
Radius of smaller circle = 
Now,
Putting radius of larger circle
Therefore,
The radius of smaller circle is 26cm.
Hence,
Option B: 26cm is the radius of smaller circle.
Answer: The experiment is blinded because the volunteers in both groups are unaware of which dog food they received.
Answer:
x= -1, x=3
Step-by-step explanation:
The “zeros” of a quadratic function are where the parabola intersects the x axis. In that graph the parabola touches x=-1 and x=-3. Therefore that is the answer.
Answer: -512
Step-by-step explanation:
(18-26) = -8
(-8)^3 = (-8)*(-8)*(-8) = -512
Just substitute the first equation into the second and solve for x: <span><span>32</span>x=−<span>12</span>x+4⟹2x=4⟹x=2</span><span>Now, since y = 3/2 * x, we have y = 3 and we are done.</span>
