When i do it, with the cone formula w volume, i get 678.567 but that’s none of your choices
Well, to solve, garph the equation y=x^2+2x-8 and y=0
see where they intersect
anyway the easier way is to factor but anyway
0=(x-4)(x+2)
anyway
solution is x=4 and -2
A and D are answers (they are same)
Answer:
4.12
Step-by-step explanation:
3√2×5×7 =3√70 { the cube root of 70} = 4.12
Please note that in proving this, I have used trigonometric identities other than just the sine angle-addition formula.
