Step-by-step explanation:
We have,
Height of cone, h = 12.7 m
Circumference of base, C = 18.9 m
The base of a circular cone is circular. The circumference of circle is given by :
r is radius
The volume of a right circular cone is given by the formula as :
26 is probably the answer
Answer:
x=y/m-y1/m+x1
Step-by-step explanation:
You have to isolate the variable by dividing each side by factors that dont contain the variable.
So 2 real solutions
just write 2 factors and expand
(x-3)(x-4)=0
x^2-7x+12=0
discriminant is when you have b^2-4ac
so subsitute
ax^2+bx+c=0
a=1
b=-7
c=12
-7^2-4(1)(12)
49-48=1
discriminant=1
one real solution would be
(x-1)(x-1)=0
x^2-2x+1=0
discriminant=-2^2-4(1)(1)=4-4=0
discriminant=0
no real solutions has the discriminant less than zero
let's say that b=1 and c=20 and a=1
basically, we need a set of numbers where b^2 is less than 4acso
1^2-4(1)(20)=1-80=-79
then we subsitute
x^2+x+20=0
Start with the slope intercept formula.
y = mx + b
Plug in the slope and coordinates for x and y and solve for b (y-intercept)
-8 = -1/2(-10) + b
-8 = 5 + b
-13 = b
Then rewrite the equation in slope intercept form
y = -1/2 x - 13
