\dfrac{x}{2.5}=\dfrac{x+2.4}{2.5+2}\\
\dfrac{x}{2.5}=\dfrac{x+2.4}{4.5}\\
4.5x=2.5(x+2.4)\\
4.5x=2.5x+6\\
2x=6\\
x=3

Use the function y = 50 tan x on the interval 0 < x < 150 Complete the ordered pair (x, 125). Round your answer to the nea
Colt1911 [192]

The value of x to the nearest whole number is 68 degrees

<h3>Equations and expressions</h3>

Given the trigonometry function shown below:

y = 50 tan x

For the coordinate (x, 125)

If the value of y is 125, then;

125 = 50tanx

tanx = 125/50

tanx = 2.5

x = arctan(2.5)

x = 68.19

Hence the value of x to the nearest whole number is 68 degrees

Find a closed-form solution to the integral equation y(x) = 3 + Z x e dt ty(t) , x &gt; 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}
