Answer:
(0,4) and (-2,0)
Step-by-step explanation:
y=3x²+4x+4
y = -2x +4
3x²+4x+4 = - 2x +4
3x²+6x=0
3x(x+2)=0
x=0, x= -2
x=0, y=-2x+4= -2*0 + 4 =4, (0,4)
x= - 2, y = 2x + 4= 2*(-2) +4=0, (-2,0)
1259.19^3
Step-by-step explanation:
A tennis ball is a sphere
Volume of a sphere ===> v=4/3 πr^3
Plug in the given info
v=4/3(3.14) (6.7)^3
Do the math to get a final answer of:
1259.19^3
The percent increase from $5.00 to $9.00 would be 80.00%
√27 can be simplified. First we split it into √9√3 because 9*3=27. Now the √9 becomes 3. We can multiply this 3 with the 3 in the beginning of the problem to get 9√3 as the final answer
Hope this helps
