Answer:
yes they are similar
step 1: flip it across the y-axis
step 2: translate it 4 units to the right and 5 units down
step 3: dilate it by a factor of 1/2
Step-by-step explanation:
121,000,000,000
this is because:
10^6= 1,000,000
10^3= 1,000
121^1= 121
To determine the effect of changing the diameter of a sphere to its volume, we would need to know the formula for the volume of a sphere which is V = 4πr³/3 where r is half of the diameter. As you can see, there is a direct relationship.
r1 = d1/2
r2 = d2/2 = 2d1/2 = d1
V2/V1 = (4πd1³/3) / (4π(d1/2)³/3)
V2/V1 = 8
Therefore, the volume of the sphere would be 8 times the original volume.
Since two people take both courses, we can subtract two from 7, 8, and 21, giving us 5, 6, and 19.
Add 5 and 6 together to get 11. Since eleven students are in those two groups, we can answer this. The answer will be 11/19.
