Answer:
The correct answer is 75 cubic feet.
Step-by-step explanation:
Volume of each block of cube is 1 cubic foot. Since the block is of the shape of a cube, the side length is 1 foot.
Number of blocks needed to fill the bottom of the the chest is 25.
Height of the chest is 3 feet.
Therefore there are three layers to be filled by blocks. Each layer needs 25 blocks each. Thus number of blocks needed to fill the whole chest is 25 × 3 = 75.
Volume of 75 blocks = Volume of the chest = 75 × 1 = 75 cubic feet.
Therefor the volume of the chest is given by 75 cubic feet.
Answer:
Interval Notation: [-2, 10]
Set Notation: {x|-2≤x≤10}
Step-by-step explanation:
Answer:
1) 18 yards
2) x = 24
3) 36 yards
4) y = (-9/98)(x - 24)² + 18
Step-by-step explanation:
The path is symmetrical about x = h
h = (10+38)/2 = 24
x = 24
Distance = 18 + 18 = 36
Vertex: (24,18)
y = a(x - 24)² + 18
At t = 10, y = 0
0 = a(10 - 24)² + 18
a = -18/14²
a = -18/196 = -9/98
y = (-9/98)(x - 24)² + 18
You just need to solve for the slope of the line.
= 12/8
= 3/2
= 1.5
