Find the length of the third side. If necessary, round to the nearest tenth.914

Zina [86]

The given trinagle is a right angle triangle. let the missing side be x. To find x, we would apply the pythagorean theorem which is expressed as

hypotenuse^2 = one leg^2 + other leg^2

From the triangle,

hypotenuse = 14

one leg = 9

other leg = x

Thus, we have

$\begin{gathered} 14^2=9^2+x^2 \\ 196=81+x^2 \\ x^2\text{ = 196 - 81 = 115} \\ x\text{ = }\sqrt[]{115} \\ x\text{ = 10.72} \end{gathered}$

To the nearest tenth, the length of the third side is 10.7

Evaluate the given integral by changing to polar coordinates. sin(x2 + y2) dA R , where R is the region in the first quadrant be

koban [17]

Set

$\begin{cases}x=r\cos\theta\\y=r\sin\theta\end{cases}\implies\mathrm dA=r\,\mathrm dr\,\mathrm d\theta$

The region $R$ is given in polar coordinates by the set

$R=\left\{(r,\theta)\mid2\le r\le3,0\le\theta\le\dfrac\pi2\right\}$

So we have

$\displaystyle\iint_R\sin(x^2+y^2)\,\mathrm dA=\int_0^{\pi/2}\int_2^3r\sin(r^2)\,\mathrm dr\,\mathrm d\theta=\boxed{\frac\pi4(\cos4-\cos9)}$

What is the first term, common difference, and 16th term

strojnjashka [21]

Answer:

The 1st term is -67

Step-by-step explanation:

I. When Sn = $\frac{n}{2}$ ( $a_{1} + a_{n}$ )

If Sn = 124, n = 8 and $a_{n}$ = 98

124 = 8/2(a + 98)

124 = 4(a + 98)

124 = 4a + 392

124 - 392 = 4a

-268/4 = a

-67 = $a_{1}$

Hope that help :D
