First you put (x+5) into the initial function wherever you see x so it becomes
(x+5)^2+3(x+5)-10=x^2+kx+30
(x^2+5x+25)+(3x+15)-10 simplified left side
x^2+8x+30 fully simplified left side 
thus k=8
x^2+8x+30=0 to find 0s
-4 + 3.7416573867739i

What is the volume of a cone with a diameter of 30 feet and a height of 60 feet use 3.14 for pie
Nesterboy [21]

Answer:

14,130 feet³

Step-by-step explanation:

2r=d

2r=30

r=15

Formula for the volume of a cone is: \frac{1}{3} *b*h

\frac{1}{3} *π*r²*h=

\frac{1}{3} *3.14*15^{2} *60=\\

\frac{1}{3} *3.14*225*60=

\frac{1}{3} *3.14*13,500=\\

\frac{13,500}{3} *3.14=\\

4500*3.14=

14,130 feet³
