Answer:

The slope is \frac{5}{7}

Step-by-step explanation:

Since, the slope of a line that passes through the points (x_1,y_1) and (x_2,y_2) is,

m=\frac{y_2-y_1}{x_2-x_1}

Thus, the slope of the line passes through the points (7,5) and (21,15) is,

m=\frac{15-5}{21-7}

=\frac{10}{14}

\implies m=\frac{5}{7}

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}

The percentage of the average yearly wage is 7.53%.

<h3>What are percentages?</h3>

Percentage can be described as a fraction of an amount that is usually expressed as a number out of hundred.

<h3>What is the percentage of the average yearly wage?</h3>

Percent = (amount spent on family holiday / total yearly wage) x 100

(1644 / 21842) x 100 = 7.53%
