A retail outlet is being designed in a strip mall in nebraska. For this outlet, the installed fiberglass insulation to protect against heat loss in the winter and heat gain in the summer will cost an estimated $100,000. The annual savings in energy due to the insulation will be $18,000 at eoy one in the 10-year life of the outlet, and these savings will increase by 12% each year thereafter. If the annual interest rate is 15%, is the cost of the proposed amount of insulation justified?
The cost of insulation is not justified because the current equivalent energy savings is $88,000, which is less than the price of insulation. Installation will set you back $90,000.
What is insulation?Insulation is defined as a material created to stop heat or sound from spreading from one place to another. Additionally helpful in lowering noise pollution is insulation. An energy-efficient home will use very little extra energy for heating and cooling.
Current equivalent energy is defined as the energy that an electron gains when its electrical potential rises by one volt. There are numerous ways that this action can occur, including thermal, electromagnetic, mechanical, and electrical. The principle of mass energy equivalence states that energy and mass have equivalent amounts.
Thus, the cost of insulation is not justified because the current equivalent energy savings is $88,000, which is less than the price of insulation. Installation will set you back $90,000.

A wheel is turning about an axis through its center with constant angular acceleration. Starting from rest, at t = 0, the wheel turns through 8. 20 revolutions in 12. 0 s. At t = 12. 0 s the kinetic energy of the wheel is 36. 0 j. For an axis through its center, what is the moment of inertia of the wheel?
Answer: 0.975 m^2
Explanation:
θ = 0.5αt^2
8.20 revolutions = 8.20 x 2π = 51.52 rad
51.52 = 0.5α(12)^2
α = 0.716 rad/s^2
ω = αt = 0.716(12) = 8.592 rad/s
KE = 1/2Iω^2
36 = 0.5I(8.592)^2
I = 0.975 m^2
Therefore, the moment of inertia of the wheel is approximately 0.975m^2

Answer: x= 4
Distribute the five, subtract fifty from both sides, divide both sides by five.
The real solution(s) of the equation (x + 10) 5 = 70 is -7.6.
What is an equation?A real solution is one that contains all the necessary constituent particles in the right ratio and has undergone the necessary dissolution. A solution is therefore referred to as a genuine solution. In algebra, a real solution is just an answer to an equation that is a real number.
There are two real solutions for x if the discriminant's value is positive, which means that the graph of the solution has two distinct x-intercepts.
There is only one actual solution for x if the discriminant's value is zero, which means that the solution's graph only has one x-intercept.
The given equation is (x + 10) 5 = 70

Evaluate the integral by making an appropriate change of variables. ∬r6sin(49x2+25y2) da, where r is the region in the first quadrant bounded by the ellipse 49x2+25y2=1.
The integral expression [tex]\int\limits \int\limits^{}_R {\sin(49x^2 + 25y^2)} \, dA[/tex] is given as a polynomial function
The result of the integral [tex]\int\limits \int\limits^{}_R {\sin(49x^2 + 25y^2)} \, dA[/tex] is [tex]\frac{\pi}{140}(1 - \cos(1))[/tex]
How to evaluate the integral?The integral expression is given as:
[tex]\int\limits \int\limits^{}_R {\sin(49x^2 + 25y^2)} \, dA[/tex]
To transform the ellipse in the form [tex]a^2x^2 + b^2y^2 = 1[/tex], we make use of the following equation
[tex]u = ax[/tex] and [tex]v = by[/tex]
So, we have:
[tex]\int\limits \int\limits^{}_R {\sin(49x^2 + 25y^2)} \, dxdy = \int\limits \int\limits^{}_R {\sin(u^2 + v^2)|J|} \, dudv[/tex]
Where:
[tex]u^2 = 49x^2[/tex] and [tex]v^2 = 25y^2[/tex]
This gives
[tex]u = 7x[/tex] and [tex]v = 5y[/tex]
And
[tex]J = \frac{x}{u} * \frac{y}{v}[/tex]
[tex]J = \frac{x}{7x} * \frac{y}{5y}[/tex]
Evaluate the product
[tex]J = \frac{1}{35}[/tex]
Substitute [tex]J = \frac{1}{35}[/tex] in [tex]\int\limits \int\limits^{}_R {\sin(49x^2 + 25y^2)} \, dxdy = \int\limits \int\limits^{}_R {\sin(u^2 + v^2)|J|} \, dudv[/tex]
So, we have:
[tex]\int\limits \int\limits^{}_R {\sin(49x^2 + 25y^2)} \, dxdy = \int\limits \int\limits^{}_R {\sin(u^2 + v^2)|\frac{1}{35}|} \, dudv[/tex]
This gives
[tex]\int\limits \int\limits^{}_R {\sin(49x^2 + 25y^2)} \, dxdy = \int\limits \int\limits^{}_R {\sin(u^2 + v^2)\frac{1}{35}} \, dudv[/tex]
Factor out 1/35
[tex]\int\limits \int\limits^{}_R {\sin(49x^2 + 25y^2)} \, dxdy =\frac{1}{35} \int\limits \int\limits^{}_R {\sin(u^2 + v^2)} \, dudv[/tex]
The equation is in the first quadrant.

[tex]\int\limits \int\limits^{}_R {\sin(49x^2 + 25y^2)} \, dxdy =-\frac{1}{70} * [\frac{\pi}{2} - 0] * [\cos(1) - \cos(0)][/tex]
Evaluate the difference
[tex]\int\limits \int\limits^{}_R {\sin(49x^2 + 25y^2)} \, dxdy =-\frac{1}{70} * [\frac{\pi}{2} ] * [\cos(1) - \cos(0)][/tex]
Evaluate cos(0)
[tex]\int\limits \int\limits^{}_R {\sin(49x^2 + 25y^2)} \, dxdy =-\frac{1}{70} * [\frac{\pi}{2} ] * [\cos(1) -1][/tex]
Evaluate the product
