The optimal height h of the letters of a message printed on pavement is given by the formula

%20%3D%20%5Cfrac%7B0.00252%20d%5E%7B2.27%7D%7D%7Be%7D" id="TexFormula1" title="h = \frac{0.00252 d^{2.27}}{e}" alt="h = \frac{0.00252 d^{2.27}}{e}" align="absmiddle" class="latex-formula">. Here d is the distance of the driver from the letters and e is the height of the​ driver's eye above the pavement. All of the distances are in meters. Find h for the given values of d and e.
d = 92.4 m, e = 1.7 m.

Answer:

The value of h is 42.956 approximately.

Step-by-step explanation:

Consider the provided formula h=\dfrac{0.00252 d^{2.27}}{e}.

Here d is the distance of the driver from the letters and e is the height of the​ driver's eye above the pavement. All of the distances are in meters.

We need to find the value of h where the value of d = 92.4 m, e = 1.7 m.

Substitute d = 92.4 m, e = 1.7 m in above formula and solve for h.

h=\dfrac{0.00252\left(92.4\right)^{2.27}}{1.7}

h\approx\dfrac{0.00252\left(28978.4648\right)}{1.7}

h\approx\dfrac{73.0257}{1.7}

h\approx42.956

Hence, the value of h is 42.956 approximately.

<span>This polygon is composed of a right triangle and <span>a parallelogram.

The area of right angle :
A_\Delta=\frac{1}{2}\cdot15\cdot8=\frac{1}{2}\cdot120=\boxed{60\ (cm^2)}

The area of the </span></span><span>parallelogram</span>:
A_P=15\cdot(13-8)=15\cdot5=\boxed{75\ (cm^2)}

The area of the polygon is equal:A=A_\Delta+A_P

Therefore, the answer is:
\boxed{\boxed{A=60\ cm^2+75\ cm^2=135\ cm^2}}

kaheart [24]

Answer:

$7.25 at part-time job

$9.00 every time lawn mowed  

       so he would get 33.33 day so we will just say 33 times to get 300 dollars if he gets $9 for mowing.  And 41.37  hours to get $300 and he would have to use x and y graph to find the boundary line.

Find the center and radius of the circle with the given equation. Then select the correct graph of the equation.
likoan [24]

Answer:

Step-by-step explanation:

In order to find the center and the radius of this circle, you have to complete the square on it. And only for the x-terms, because the y term is squared and there is no other y term. We'll get to that in a second.

Take half the linear x-term, square it and add it to both sides. Our linear term is 10. Half of 10 is 5, and 5 squared is 25. We add 25 to both sides:

The reason we do this is to create a perfect square binomial inside that set of parenthesis. Simplifying the right side as well gives us:

This tells us that the center is (-5, 0). Remember when I said we would get back to the y terms? Because there was only a y-squared and no other y terms, that is the same as writing the equation as

The radius is the square root of the constant. So the radius is 6.

D is the graph you want.
