P=160-70*cos(2π*(1/12)*t)
• Pressure in mathematics or physics is defined as force per unit area. The pressure exerted by a solid object which is resting on top of a solid surface is the weight divided by the area of the object . SI unit of force is Newton (N).
First, we find the amplitude by taking the difference between the peak values and dividing by two:
Amplitude=(230+90)/2=70
We can find the center value by either adding 70 to the minimum or subtracting 70 from the maximum:
90+70=160
230-70=160
This tells us that the Center Value=160
The frequency that we are operating at is given as:
f = 5/hour
so in minutes
f=5*(1/60)/minute=5/60=1/12 per minute
So, combining everything we get
P=160-70*cos(2π*(1/12)*t)

Bernite is selling candy bars for a school fundraiser. The school paid $20.00 for a box of 15 king-size candy bars and Bernite sells then for $2.00 each. What is the relationship the amount of candy sold and the amount of money earned? (Multiple answer choice)
a. The relationship is linear
b. The relationship is non-linear
c. The relationship is proportional
d. The relationship always results in a positive profit.
e. The relationship always results in a negative profit
Answer:
e. The relationship always results in a negative profit
b. The relationship is non-linear
Step-by-step explanation:
From the question above it could be found that, the relationship always result in negative profit. This is because:
To the school purchase,
Selling price of Candy bars in a box = $20.00
On the other hand,
Each Candy bar cost = $2.00
No of Candy bars in a box = 15
Total cost = $2.00 x 15 = $30.00
Loss (negative profit) = Total cost - Selling price
= $30.00 - $20.00 = $10.00
This also shows that, the relationship is non-linear because there is no direct relationship between the selling price and the expected profit that was supposed to have been earned.

Challenge of the day
Answer:
11+x+13=40
Step 1: Simplify both sides of the equation.
11+x+13=40
(x)+(11+13)=40(Combine Like Terms)
x+24=40
x+24=40

x+24−24=40−24
x=16
Answer:
x = 16
Step-by-step explanation:
11 + x + 13 = 40
x + 24 = 40
x = 40 - 24
x = 16

As society gets more advanced, there would need to be a change to the percentage tax structure to make it more progressive so that the rich pay more taxes.
The best way to make this adjustment is by passing laws.
How should taxes change as society advances?
As the society advances, there will be those who are richer and wealthier than others. They would need to take more care of society and the people who are not as fortunate as them because society would become more empathetic.
For this to happen, society would have to enact progressive tax rates where people who are wealthier pay more. This adjustment is best done by passing relevant taxation laws.

Plz put the answer with clear explanation.
Answer:
10500 rupees
Step-by-step explanation:
So 50 bags 300 per pack so
300*50= 15000
15000 is what he spent on the 50 bags of rice
So he spent 500 rupees on transportation
15000 + 500 = 15500 total spent which is not needed but extra information
30% loss is 30% of 15000 so
30% of 15000 = 4500
15000 - 4500 = 10500 rupees

Answer:
4.5*10^(4)*(6.8*10^(-8)=3.06*10^-3
(2.8*10^(2)*(6.5*10^(-7)=1.82*10^-4
((5.6*10^(-3))*(7.7*10^(-9)))/((8*10^(-2))*(3.5*10^(-6)))=1.54*10^-4
then the other fraction one equals 9.45*10^-4
Step-by-step explanation:
Solving the first expression, we have:
(4.5⋅10^4)⋅(6.6⋅10^−8)
=30.6⋅10^−4
=3.06⋅10^−3
So the first expression goes into the second box.
For the second one, we have:
(2.8⋅10^2)⋅(6.5⋅10^−7)
=18.2⋅10^−5
=1.82⋅10^−4
So the second expression goes into the first box.
Put the third expression into the fourth box and the fourth expression into the third box

Ten students are chosen from a statistics class of 22 students. Let X be the number who got an "A" in the class. Is this a binomial distribution, and if so, what is the number of trials?
Answer:
Yes, this is a Binomial distribution, and the number of trials is 10.
Step-by-step explanation:
From the given information:
We are being told that ten students are chosen from a statistics class of 22 students.
If X represents the random variable for the number of students who got an "A" in the class.
Then we have two possible outcomes;
Number of students that got an "A" = (Success)
Number of students that did not get an "A" = (Failure)
Thus, this is a Binomial distribution because it consists of two outcomes, and the number of trials is 10.

In this problem we find a picture containing the graphs of two functions, of which we must find both the domain and the range of each expression. The domain of the function corresponds with all values from the horizontal axis such that the function exists, and range of the function with all the values from the vertical axis.
The domain and range of the first function are x ∈ [- 4, 4] and y ∈ [1, 5], respectively.
