Answer:
Step-by-step explanation:
Given that,
Radius of cone, r = 7 inches
Slant height of the cone, l = 11 inches
We need to find the height of the cone. Let the height be h. Using trigonometry to find it as follows :
So, the height of the cone is equal to .
Answer:
x=33.5
Step-by-step explanation:
(x − 21)2 = 25
2x-42=25
2x=67
x=33.5
The less dense liquids and objects will be found at higher levels in the vase.
The density of the water would not change. Density for a substance is constant, regardless of the amount of that substance.
Let f(x) = sqrt(x). Use linear approximation about x = 25, since 24 is close to 25, and since it is easy to take the square root of 25.
Note that f ' (x) = 1/[2sqrt(x)] from the power rule.
About x = 25, f(x) is approximately f(25) + f ' (25)(x - 25).
So sqrt(24) = f(24) is approximately
f(25) + f ' (25)(24 - 25) = sqrt(25) + {1/[2sqrt(25)]}(-1) = 5 - 1/10 = 4.9 .
