Answer:

120 m^2

Step-by-step explanation:

A_1 = l * w = 9 * 5 = 45\ m^2

A_2 = 2 * \frac{b*h}{2} = 2 * \frac{3*4}{2} = 3*4 = 12\ m^2

A_3 = l * h = 9 * 3 = 27\ m^2

A_4 = l * w = 9 * 4 = 36\ m^2

A = A_1 + A_2 + A_3 + A_4 = 45 + 12 + 27 + 36 = 120\ m^2

Evaulate the function at the indicated values h(t)=t+(3/t)i find h(x-1)
alex41 [277]

<span>h<span>(t)</span>=<span>t<span>34</span></span>−3<span>t<span>14</span></span></span>

Note that the domain of h is <span>[0,∞]</span>.

By differentiating,

<span>h'<span>(t)</span>=<span>34</span><span>t<span>−<span>14</span></span></span>−<span>34</span><span>t<span>−<span>34</span></span></span></span>

by factoring out <span>34</span>,

<span>=<span>34</span><span>(<span>1<span>t<span>14</span></span></span>−<span>1<span>t<span>34</span></span></span>)</span></span>

by finding the common denominator,

<span>=<span>34</span><span><span><span>t<span>12</span></span>−1</span><span>t<span>34</span></span></span>=0</span>

<span>⇒<span>t<span>12</span></span>=1⇒t=1</span>

Since <span>h'<span>(0)</span></span> is undefined, <span>t=0</span> is also a critical number.

Hence, the critical numbers are <span>t=0,1</span>.

I hope that this was helpful.
