To solve this, we would need to know some trigonometry.
To solve this, the equation would be this:
tan 37= x/3.
If we solve this, line segment DE would be approximately 2.26.
Hope this helps.

Please help me asap. Got stuck with this question

Temka [501]

Answer:

Step-by-step explanation:

$a.\\\frac{d}{dx}(\frac{-1}{1+x^2} )=\frac{d}{dx} [-1(1+x^2)^{-1}]=-1(-1)(1+x^2)^{-2}(2x)=\frac{2x}{(1+x^2)^2 }\\$

put 1+x²=u

2x dx=du

when x=0,u=1

when x=2,u=1+2²=5

$\int\limits^5_1 {\frac{1}{u}} \, du= ln |u| ,1 \to 5=ln5-ln1=ln 5-0=ln 5$

Each of the following integrals represents the volume of either a hemisphere or a cone, and the variable of integration measures

iris [78.8K]

Answer:

1. cone

radius, height = 2, 10

volume = 13.33

2. hemisphere

radius= 14

volume = 1829.33

Step-by-step explanation:

The region described has a radius r=2−y/5, therefore, the volume is a cone

radius, height = 2, 10

volume =

$\int\limits^{10}_0 {\pi ( 2-\frac{y}{5} )^2} \, dy \\=$

= 13.33

2. The region ∫14 0 π(196 - h^2) dh has a radius 196 - h^2, so the volume is a hemisphere

radius = 14

volume

= $\int\limits^{14}_0 {\pi (196 - h^{2} )} \, dh$

= $\pi (196h- \frac{h^3}{3}) |^{14}_0$

=1829.33
