I need help on question 16 &amp; 17! <br> I don’t really understand how to solve it.
Sidana [21]

Answer:

y = 11

x = 8.6

Step-by-step explanation:

The small triangle with 30,32,y looks like right triangle

so according to formula a^2 + b^2 = c^2

so 30^2 + y^2 = 32^2

900 + y^2 = 1024

y^2 = 124 => y = 11

The larger triangle also looks like a right triangle

so according to formula a^2 + b^2 = c^2

(30 + 10)^2 + 22^2 = (32 + x)^2

1600 + 44 = (32 + x)^2

so (x + 32)^2 = 1644

x + 32 = 40.55

x = 40.55 = 32 = 8.55 = 8.6

Consider f and c below. f(x, y) = (7 + 8xy2)i + 8x2yj, c is the arc of the hyperbola y = 1/x from (1, 1) to 3, 1 3 (a) find a fu
KonstantinChe [14]

\dfrac{\partial f}{\partial x}=7+8xy^2

\dfrac{\partial f}{\partial y}=8x^2y

The first equation gives

f(x,y)=7x+4x^2y^2+g(y)

Differentiating with respect to y gives

8x^2=8x^2y+\dfrac{\mathrm dg}{\mathrm dy}\implies\dfrac{\mathrm dg}{\mathrm dy}=0\implies g(y)=K

for some constant K. So

f(x,y)=7x+4x^2y^2+K

and by the fundamental theorem of calculus,

\displaystyle\int_C\nabla f\cdot\mathrm d\vec r=f\left(3,\frac13\right)-f(1,1)=25-11=\boxed{14}

Latoya, Henry, and Manuel served a total of 112 orders Monday at the school cafeteria. Latoya served 7 more orders than Henry. M
Anarel [89]

Answer:

Henry: 21

Latoya: 28

Manuel = 63

Step-by-step explanation:

x = orders henry served

x + 7 = orders latoya served

3x = orders manuel served

x + (x + 7) + 3x = 112

5x + 7 = 112

5x = 105

x = 21

x + 7 = 21 + 7 = 28

3x = 3 * 21 = 63
