Answer:
The area of a horizontal cross section at a height is 
Step-by-step explanation:
Given that,
Height = 14 m
Radius = 2 m
Let V be the volume of a right circular cone
We need to calculate the value of R
Using given data
Put the value into the formula
We need to calculate the area of a horizontal cross section at a height y
Using formula of area
Put the value into the formula
Hence, The area of a horizontal cross section at a height is
Answer:
the line goes through 1 from x axis and in the same time the line continue his trip and goes through 4 from y axis
so now we have rule to use to find the equation
y/4+x/1=1
y/4=1-x
y=4-4x
and this is the equation
Answer:
ooh this hard um...
Step-by-step explanation:
isn't that impossible?
144pi units³ is the answer on apex
Answer:
x = -4, -2
Step-by-step explanation:
Given equation is,
x² + 6x + 8 = 0
Let the equation to be graphed is,
y = x² + 6x + 8
y = x² + 2(3x) + 9 - 1
y = x² + 2(3x) + 3² - 1
y = (x + 3)² - 1
Table for the Input-output values
x -6 -4 -3 -2 -1 0
y 8 0 -1 0 3 8
Now we can plot these points on the graph as attached.
Since, this graph is intersecting x-axis at x = -4, -2
Therefore, solutions of the given equation will be x = -4, -2
