Answer:
6n-2 = 22
Step-by-step explanation:
n = 4
6(4)-2
24-2
22
Requied equation is (x - 0)^2 = 4p(y - 0)
x^2 = 4py
But 0 + p = 0.75 => p = 0.75
Therefore, equation is x^2 = 4(0.75)y
x^2 = 3y
y = 1/3 x^2
Answer:
False.
Step-by-step explanation:
A cone is not a solid made from a disc, a point not in the same plane as the discs and all points between them.
Mathematically, the volume of a cone is given by the formula;
Where;
V is the volume of the cone.
r is the radius of the base of the cone.
h is the height of the cone.
<h2>p=7</h2>
Step-by-step explanation:
![5p = 35](https://tex.z-dn.net/?f=5p%20%3D%2035)
Divide both sides of the equation by 5
![\frac{5p}{5} = \frac{35}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5p%7D%7B5%7D%20%20%3D%20%20%5Cfrac%7B35%7D%7B5%7D%20)
Simplify
![5p \div 5 = p \\ 35 \div 5 = 7 \\ p = 7](https://tex.z-dn.net/?f=5p%20%5Cdiv%205%20%3D%20p%20%5C%5C%2035%20%5Cdiv%205%20%3D%207%20%5C%5C%20p%20%3D%207)
Answer:
35 ft
Step-by-step explanation:
The arch is in the shape of a semicircle.
The distance around the arch is about 110 feet. This is the same as the circumference of the arch.
The height of the arch is the radius of the arch.
The circumference of a semicircle is given as:
![C = \pi r](https://tex.z-dn.net/?f=C%20%3D%20%5Cpi%20r)
where r = radius
Therefore:
110 = πr
=> r = 110/π
r = 35.01 ft ≅ 35 ft
The height of the arch is 35 ft
