Barbara has a rectanglar shaped mouse pad the longest side of the mouse pad is 8 inches and the shortest side is 3 inches what i
1 answer:
Answer:
1) 22 inches, 24
Step-by-step explanation:
Barbara has a rectangular shaped mouse pad
Let the length of mouse pad = 8 inch
Breadth of a mouse pad= 3 inches
Perimeter of mouse pad= 2(l+b)
Perimeter of mouse pad= 2(8+3)
Perimeter of mouse pad= 2×11 inch
Perimeter of mouse pad= 22 inches
Area of a mouse pad= l×b
Area of a mouse pad= 8×3
Area of a mouse pad= 24

Answer:
The volume of the cylinder is 3 times the volume of the cone
Step-by-step explanation:
The formula for the volume of the cylinder is given by :
.....(1)
Where
r and h are the radius and the height of the cylinder
The formula for the volume of the cone is given by :
...(2)
From equation (1) and (2),
So, the volume of the cylinder is 3 times the volume of the cone.
The horizontal distance from the firefighter at which the maximum height of water occurs is 10.83m
<u>Explanation:</u>
Given:
h(x) = -0.026x² + 0.563x + 3
where,
h(x) is the height of the water
Initial speed, u = 14m/s
angle, θ = 30°
(a)
Horizontal distance = ?
h(x) = ax² + bx + c
the vertex is found at x = -b/2a
where,
x = distance to the maximum height
As compared to the equation given:
a = -0.026
b = 0.563
Thus,
Therefore, horizontal distance from the firefighter at which the maximum height of water occurs is 10.83m
