Answer:

A.2√34

Step-by-step explanation:

1 side=10 units

2nd side=6 units

By Pythagoras theorem

The line segment will be

√(10^2 + 6^2)

√136

2√34

Answer:

i think it's A 2✓34

Step-by-step explanation:

because if u used physagorean law

√((5+1)^2+(8+2)^2)= 2√34

Evaluate the line integral, where c is the given curve. (x + 9y) dx + x2 dy, c c consists of line segments from (0, 0) to (9, 1)

viktelen [127]

$\displaystyle\int_C(x+9y)\,\mathrm dx+x^2\,\mathrm dy=\int_C\langle x+9y,x^2\rangle\cdot\underbrace{\langle\mathrm dx,\mathrm dy\rangle}_{\mathrm d\mathbf r}$

The first line segment can be parameterized by $\mathbf r_1(t)=\langle0,0\rangle(1-t)+\langle9,1\rangle t=\langle9t,t\rangle$ with $0\le t\le1$ . Denote this first segment by $C_1$ . Then

$\displaystyle\int_{C_1}\langle x+9y,x^2\rangle\cdot\mathbf dr_1=\int_{t=0}^{t=1}\langle9t+9t,81t^2\rangle\cdot\langle9,1\rangle\,\mathrm dt$
$=\displaystyle\int_0^1(162t+81t^2)\,\mathrm dt$
$=108$

The second line segment ( $C_2$ ) can be described by $\mathbf r_2(t)=\langle9,1\rangle(1-t)+\langle10,0\rangle t=\langle9+t,1-t\rangle$ , again with $0\le t\le1$ . Then

$\displaystyle\int_{C_2}\langle x+9y,x^2\rangle\cdot\mathrm d\mathbf r_2=\int_{t=0}^{t=1}\langle9+t+9-9t,(9+t)^2\rangle\cdot\langle1,-1\rangle\,\mathrm dt$
$=\displaystyle\int_0^1(18-8t-(9+t)^2)\,\mathrm dt$
$=-\dfrac{229}3$

Finally,

$\displaystyle\int_C(x+9y)\,\mathrm dx+x^2\,\mathrm dy=108-\dfrac{229}3=\dfrac{95}3$

The y intercept. Plz help I’m so confused and I may ask some questions later as long as I don’t have to pay. Thank you so much I

Masteriza [31]

If you are trying to find the y intercept then you have already found it, it is 4. From that point you would then draw the rest of the slope.

Instead of drawing from (0,0) you would go up 4 units and then do rise over run (7/3) to plot your line.

For non-zero denominators, simplify: <img src="https://tex.z-dn.net/?f=%5Cfrac%7B3a%5E3-75a%7D%7Ba%28a%2B5%29%28a%2B5%29%7D" id=

Debora [2.8K]

$\frac{3a^3-75a}{a(a+5)(a+5)}=\frac{3a(a^2-25) }{a(a+5)(a+5)}=\frac{3a(a - 5)(a+5) }{a(a+5)(a+5)} =\frac{3 (a - 5) }{ (a+5) }$
