Answer:

$S_{1 } (x,y) = (0.333, 0.815)$ (Absolute minimum) and $S_{2} (x,y) = (-1, 2)$ (Absolute maximum)

Step-by-step explanation:

The critical points are determined with the help of the First Derivative Test:

$f'(x) = 3\cdot x ^{2} +2\cdot x -1$

$3\cdot x^{2} + 2\cdot x - 1 = 0$

The critical points are:

$x_{1} \approx 0.333$ and $x_{2} \approx -1$

The Second Derivative Test offers a criterion to decide whether critical point is an absolute maximum and whether is an absolute minimum:

$f''(x) = 6\cdot x +2$

$f''(x_{1}) = 3.998$ (Absolute minimum)

$f''(x_{2}) = -4$ (Absolute maximum)

The critical points are:

$S_{1 } (x,y) = (0.333, 0.815)$ (Absolute minimum) and $S_{2} (x,y) = (-1, 2)$ (Absolute maximum)

Find x on this special right triangle

tigry1 [53]

Answer:

The answer is 7

Step-by-step explanation:

We know than Tan45=1

Tanx=opp/adj

tan45=y/(7 $\sqrt{2}$ )/2

Thus y=7 $\sqrt{2}$ /2

We know by pythagoras theorem that hyp^2=side^2+side^2

$x^{2}$ =( $(7\sqrt{2} /2)^{2}$ + $(7\sqrt{2}/2)^{2}$

$x^{2}$ =(49(2)/4)+(49(2)/4)

$x^{2}$ =(49/2)+(49/2)

$x^{2}$ =(98/2)

$x^{2}$ =49

x=7

Help pleaseeeee I’m confused

Aleks04 [339]

Answer:

62 m

Step-by-step explanation:

let the height of tower=x

then $\frac{x}{36.25} =\frac{2.8}{1.63} \\x=\frac{2.8}{1.63} \times 36.25 \approx 62.27 ~m \approx 62 m$
