Prove that the inequality<br> x(x+ 1)(x+ 2)(x+ 3) ≥ −1<br> holds for all real numbers x.
vredina [299]
(x²+x)(x²+5x+6) = x^4 + 6x³ + 11x² + 6x  + 1 ≥0
f(x) = x^4 + 6x³ + 11x² + 6x  + 1
f'(x) = 4x³ + 18x² +22x +6 
racines x1 = -0,301 x2 = -1,5 x3 = -2,618
variations 

x                                  -2,62                    -1,5                   -0,3
f'(x)                      -          0             +          0           -            0          +
f(x)    -inf            \            0             /                        \             0           /

Find the missing angle! Please add an explanation!
AlladinOne [14]

Answer:

The answer is: 58^\circ

Step-by-step explanation:

If we add the angles inside a triangle, we must have 180^\circ. So we have an 57^\circ angle and an 65^\circ angle, their sum is 122^\circ, so the missing angle must be 180^\circ-122^\circ=58^\circ

Find the surface area and volume of the composite figure. Use 3.14 for π and round to the nearest tenth if needed.
Vesnalui [34]

Answer:

Step-by-step explanation:

The shape consists of three parts: a half sphere, a round cylinder and a round cone.

The half sphere volume = 1/2 * 4/3 * π * (4)^3

= 32/3 π

The round cyllinder volume = π * (4)^2 * 10

= 160 π

The round cone volume = 1/3 * π * (4)^2 * 3

= 16 π

Adding them together, the volume of shape

= 32/3 π + 160π + 16π

= (32/3 + 160 + 16)*3.14

= 586.13

Similarly the surface area

= (4π4^2)/2 + 2π4*10 + π*4*5

= (32+80+25)*3.14

= 430.18
