For time t≥0 , the acceleration of an object moving in a straight line is given by a(t)=sin(t23). what is the net change in velocity from time t=0. 75 to time t=2. 25 ?
The net change in velocity during the given time interval is equal to -0.665.
Given the following data:
Initial time = 0.75 seconds.Final time = 2.25 seconds.Acceleration, [tex]a(t) = sin(\frac{t^2}{3} )[/tex]How to calculate the net change in velocity.Since acceleration is the rate of change of velocity of an object, we would derive an expression for the velocity by differentiating with respect to time:
[tex]V(t) = \frac{d}{dt} a(t)\\\\V(t) = \frac{d}{dt} (sin(\frac{t^2}{3} ))\\\\V(t) = cos( \frac{t^2}{3})(\frac{2t}{3})\\\\V(t) = \frac{2t}{3}cos( \frac{t^2}{3})[/tex]
Substituting the time interval, we have:
[tex]V(t) = \frac{2\times 2.25}{3}cos( \frac{2.25^2}{3})- \frac{2\times 0.75}{3}cos( \frac{0.75^2}{3})\\\\V(t) = \frac{4.5}{3}cos( \frac{5.0625}{3})- \frac{1.5}{3}cos( \frac{0.5625}{3})\\\\V(t) =1.5(-0.11643)-0.5(0.98247)[/tex]
V(t) = -0.665.

A family is paying to heat their house in Chicago, Illinois. Calculate the cost of heating the house
for one winter. Assume the following:
• The house has 2,000 square feet of living space.
• 100,000 BTUs of heat per square foot are required to heat the house for the winter.
• natural gas is available at a cost of $6.00 per thousand cubic feet
• one cubic foot of natural gas supplies 1,000 BTUs of heat energy
• the furnace in the house is 70% efficient
.
Natural gas is available at a cost of $6.00 per thousand cubic feet.
One cubic foot of natural gas supplies 1,000 BTUs of heat energy.
• The furnace in the house is 70 percent efficient.
If the natural gas is available at a cost of $6.00 per thousand cubic feet. The cost of heating the house is: $1,714.
Cost of heating the houseFirst step is to calculate number of cubic feet of natural gas required to heat the house for one winter.
Number of cubic feet=(2000 ft²)× (100,000 BTU/ft³) ×(1 ft³÷1000 BTU)×(1 BTU(in)÷0.7 BTU (out))
Number of cubic feet = 285,714 ft³
Second step is to calculate the cost of heating the house
Cost of heating the house=(285,714 ft³)× ($6.00÷1000 ft³)
Cost of heating the house=$1,714
Inconclusion the cost of heating the house is: $1,714.

Help me I need a five - paragraph essay about an opinion on Your principal wants to invite a special guest to speak to all the students about the value of hard work and is trying to decide which person to bring in: a scientist or an athlete. Which speaker would you pick to come to your school to talk about the value of hard work, and why?
Answer:
The principal is very skeptical about this decision because if the decision she makes is athlete, he will make a speech about physical aspects, most likely, and if the choice is the scientist, then he will talk about science and academic aspects, probably. Both of these are excellent, but if the speech is about both, the athlete will be more reliable. And if the students are not very good at studies, the scientist is better, speaking he can teach a lot more than the athlete, who can do both pretty good. So, the choice is difficult.
First and foremost, an official athlete will teach the school about work ethics like dedication which is good for both grades and physical stuff. But, sadly, it will be targeted at physical aspects and might be slightly poor. However, the athlete can teach the students so very well that they excel. So, the athlete is an excellent choice.
The scientist is better academically, but not in the field of hard work. The athlete is better at that field. But, the scientist can teach them a little about the EDP, which relates to work ethics more specifically. It also talks about the importance of determination, which is a key concept in hard work. The question remains: which should the principal invite?
The principal should invite the athlete because he has more experience in hard work and is less of the office and science sort of work style. The athlete also doesn't go to a job and sit down for eight hours, and therefore knows more about hard work. The scientist would be more helpful for stuff like determination or patience, more of which show up in scientific occupations of study.
The principal had a tricky decision, but now she knows the answer to it, athlete! The scientist is great, but in this case, the athlete is better. We have seen each in their respected career and evaluated what they will most likely teach, and finally chose the best option.

We cannot write a mathematical equation for the two conditions, however a computer program can wok out the condition and given the right output
Mathematical EquationsThe main reason why a single mathematical equation cannot work in this case is because the cost is not fixed, and the number of books also changes, hence two variable value.
In this type of condition a computer program will work best by setting a condition based on the number of books to be purchase, of 6 the price should be $3.60 and if 10 the price should be $5.5
