zubka84 [21]

It would take Adrian 4 days, if you add 3/4 four times all together you will end up with 12/4. Then you have to simplify it, getting the answer 3. Hope this helped! :)

The diameter is a circle is 16cm. Find it’s circumference in terms of π.<br><br> C= ________cm

Paraphin [41]

Answer:

Circumference of the circle = 100.53 in.

Step-by-step explanation:

Circumference of a circle is given by the formula,

Circumference = 2πr

Radius of the circle 'r' = 16 in.

Therefore, circumference of the circle with radius 16 in will be,

C = 2π(16)

C = 32π

C = 100.53 in.

Find a closed-form solution to the integral equation y(x) = 3 + Z x e dt ty(t) , x > 0. In other words, express y(x) as a fun

MrMuchimi

Answer:

$y{x} = \sqrt{7+2Inx}$

Step-by-step explanation:

$y(x)= 3 + \int\limits^x_e {dx}/ \, ty(t) , x>0}$

Let say; By y(x)= y(e)

we have;

$y(e)= 3 + \int\limits^e_e {dt}/ \, ty= 3+0$

Using Fundamental Theorem of Calculus and differentiating by Lebiniz Rule:

$y^{1} (x) = 0 + 1/ xy$

$y^{1} = 1/xy$

dy/dx = 1/xy

$\int\limits {y} \, dxy = \int\limits \, dx/x$

$y^{2}/2 Inx + C$

RECALL: y(e) = 3

$(3)^{2} / 2 = In (e) + C$

$\frac{9}{2} =In(e)+C$

$\frac{9}{2} - 1 = C$

$\frac{7}{2} = C$

$y^{2} / 2 = In x +C$

$y^{2} / 2 = In x +7/2$

MULTIPLYING BOTH SIDE BY 2 , TO ELIMINATE THE DENOMINATOR, WE HAVE;

$y^{2} = {7+2Inx}$

$y{x} = \sqrt{7+2Inx}$

Please help me thank you and show all work

AleksAgata [21]

Proportional:
82.8 / 92 = 0.9
73.8 / 82 = 0.9
so
FG / 47 = 0.9
FG = 47 * 0.9
FG = 42.3

answer

The distance between 2 campsites is 42.3 m.
