Answer: 8 vertices
Step-by-step explanation: A cube has 6 square faces. Each segment formed by the intersection of 2 faces is called an edge so a cube has 12 edges. Each point formed by the intersection of 3 edges is called a vertex so a cube has 8 vertices.
Answer:
3/2 and 3/4 are terminating decimals
Step-by-step explanation:
Terminating decimals are those whose decimals end.

Answer:
a.
Step-by-step explanation:
The direct path back forms a right triangle. Use the Pythagorean theorem:
X = sqrt(4^2 + 2^2)
X = sqrt(16 + 4)
X = sqrt(20) = 2sqrt(5)
X = 4.472
Round the answer as needed.
X=3 and y=x^2 intersect at (3,9), so your bounds are y=4 and y=9 and and . , so you use the disk method therefore you have to switch variables (even though x^2 is not invertible, because you only need the right side you can use y^(1/2)) so pi*integral( 3^2- (y^(1/2))^2 dy) making it pi*[9y-(1/2)y^2]|y=(4,9) , pi*[25/2]
