Surface area of a ball:
S=4πr^2=4*π*5^2=100π
Volume of a circle:
V=4/3*π*r^3=4/3*π*125=(500/3)*π=165π
The approximate surface-area-to-volume ratio would be 1:1,5
X^2+x-12=0 factors out into (x+4)(x-3) so the answer is: x=-4, x=3
Subtract 2 from both sides
3x+2-2=5-2
3x=3
Divide both sides by 3
3x/3= 3/3
The answer is ×=1
The domain of the function is the set of all the values of x that would allow the function to have real values. Since the radicand is x - 3, the value of x cannot be less than 3 because that would make the value of sqrt (x - 3) an imaginary number. Thus, the domain should be all numbers GREATER than or equal to 3.
Answer:
1.8
Step-by-step explanation:
(2x90):100
180:100 = 1.8
