Answer:
Step-by-step explanation:
We have,
Height of a cone is 12 feet
Volume of the cone is 90 feet
It is required to find the area of the base of the cone.
The base of a cone is circular in shape.
The formula used to find the volume of a cone is given by :
here, 
(area of base of cone)
So, the area of the base of the cone is 
.
Volume ratio = 1331/729 which is the cube of the linear scale factor.
To find the linear scale factor, let find the cubic root of the numerator & the denominator:
∛1331 = ∛11³ = 11
& ∛729 = ∛9³ = 9
So the linear scale is 11/9 ==> then the ratio of their surface area will be:
11²/9² ==> 121/81.
Note, if you have a linear scale, then the surface will be the square othis scale & the volume will be the cube of the linear scale
Answer:
y=x+10
Step-by-step explanation:
1.) y-1=1(x+9)
2.) y-1=x+9
3.) y=x+10
Answer:
Step-by-step explanation:
hello :
put x = -5 in this equation : a(4-x) =-3x + b
a(4+5) =15 + b
9a = 15 +b
b = 9a - 15
the values of a and b is all order pair : ( a ; 9a-15) a real number
Answer:
Ex1. X=-1
Ex2. 3rd choice
Step-by-step explanation:
Ex1. The only discontinuity in the domain is x=-1
Ex2. You just add values of x to those options and see which one applies
