Food B costs $ 2 per pound and contains 700 calories. Food C costs $ 3 per pound and contains 600 calories No more than 0.75 pounds of food C can be used per resident. No less than 2 pounds of food B should be used per resident. The objective is to feed the students at the least cost, but the diet must have at least 1800 calories.
If we define the decision variables as A: pounds of food A, B: pounds of food B, and C pounds of food C, the object function is to minimize Blank 1. In addition to non-negative constraints, other constraints are Blank 2,Blank 3, and Blank 4.
(1. No need to use multiplication sign. For example, just write 10A not 10*A. For greater(less) than sign, just write it as >= (<=).
2. Also please leave no space in equation. For example, write A<=100, not A <= 100.
3. Please write decimal number for example as 0.32 not .32 when applicable. )
This problem is designed to minimize the cost of feeding students in the dorms while providing a minimum of 1800 calories. The objective function is to minimize the cost of the diet, which is calculated by multiplying the pounds of each food by its cost and adding them together. The constraints of the problem are that A must be greater than or equal to 0, B must be greater than or equal to 2, and C must be less than or equal to 0.75.
1. 2.25A + 2B + 3C

Explanation needed
The angle whose supplement is 30 degrees greater than 4 times the supplement is 30°
What are supplementary angles?Two angles are called supplementary when their measures add up to 180 degrees.
For example:- 120° and 60°, 110° and 70°, 140° and 40°, 90° and 90°, 20° and 160°, 135° and 45° are some example of supplementary angles.
Given that, an angle whose supplement is 30 degrees greater than 4 times the supplement.
Let the angle asked be x,
Therefore, the supplement of x, will be = 180°-x
According to the question, Its supplement is 30 degrees greater than 4 times the supplement.
Therefore, establishing the equation,
So, for solving for x, we have,
180°-x = 30°+4x
4x+x = 180°- 30°
5x = 150°
5x/5 = 150°/5
x = 30°
As, we considered the angle asked be x,
Hence, the angle whose supplement is 30 degrees greater than 4 times the supplement is 30°

In 2012, the population of a city was 5.89 million. The exponential growth rate was 3.42% per year.
a) Find the exponential growth function.
b) Estimate the population of the city in 2018.
c) When will the population of the city be 8 million?
d) Find the doubling time.
The general form of exponential formula is y = a * b^x, the population of the city in 2018 6.058454 million.(c) the population of the city be 8 million19.38548963 years.
How to find the population?In this problem, a = 5.21 million and b = 1 + 2.86%/100 = 1.0286.
a is a constant.b is the basex is the exponent.In 2012, the population was 5.89 million.
In 2018, the population will be 5.89 * 1.0286 ^ (2018 - 2012) = 5.89 * 1.0286 ^ 6 = 6.058454 million.
To find when the population will be 9 million, your equation becomes:
9 = 5.21 * 1.0286 ^ x divide both sides of this formula by 5.21 to get:
9/5.21 = 1.0286 ^ x take the log of both sides of the equation to get:
log(9/5.21) = log(1.0286^x) since log(1.0286^x) = x * log(1.0286), the equation becomes:
log(9/5.21) = x * log(1.0286)
Divide both sides of this equation by log(1.0286) to get:
log(9/5.21) / log(1.0286) = x
Solve for x to get:
x = 19.38548963.
Confirm by replace x in the original equation to get:
9 = 5.21 * 1.0286 ^ 19.38548963 becomes 9 = 9.
This confirms the value of x is good.
The population will grow to 9 million in 19.38548963 years.
To find when the population will double, the equation becomes:
2 = 1 * 1.0286 ^ x
Simplify to get:
2 = 1.0286 ^ x
Take the log of both sides of this equation to get:
log(2) = log(1.0286 ^ x)
Since log(1.0286 ^ x) = x * log(1.0286), this equation becomes:
log(2) = x * log(1.0286)
solve for x to get:
x = log(2) / log(1.0286) = 24.5808602.
to confirm this is true, replace x in the original equation to get:
2 = 1.0286 ^ 24.5808602 which becomes 2 = 2.
This confirms the value of x is true.
The population will double in 24.5808602 years.

Find the domain of y considered as a function over the reals. (Enter your answer using interval notation.)

We have to find the domain of y considered as a function over the reals.
The differential equation is y' + 2x[tex]y^2[/tex] = 0
The solution of the given differential equation is y = 1/([tex]x^2[/tex] + c)......(1)
The given initial value; y(-3) = 1/4
Replace the initial value in the first-order DE solution provided. To obtain the equation for y, locate the constant c and then re-substitute 'c'.
Now put x = -3 and y(-3) = 1/4 in equation 1
[tex]\frac{1}{4}=\frac{1}{(-3)^2+c}[/tex]
[tex]\frac{1}{4}=\frac{1}{9+c}[/tex]
9+c = 4
Subtract 9 on both side, we get
c = -5
Now substitute the value of c again in equation 1
y = [tex]\frac{1}{x^2-5}[/tex]
To find the domain of y we can write it as
y = [tex]\frac{1}{(x)^2-(\sqrt{5})^2}[/tex]
Now the simplified form is
y = [tex]\frac{1}{(x-\sqrt{5})(x+\sqrt{5})}[/tex]

Analyze the diagram of the trapezoid gives BA = 10.5 units
How to find the side BA of the trapezoid the analyzing the diagram?A trapezoid (also known as a trapezium) is a four-sided geometric shape that has two parallel sides (the bases) and two non-parallel sides (the legs). The bases of a trapezoid can have different lengths, but the legs must be congruent and parallel to each other.
Let's analyze the diagram below and complete the instructions:
Since CB / CA = DE / DF
where CB = 6, DE = 4, EF = 7
We can say:
DF = DE + EF = 4 + 7 = 11
CA = CB + BA = 6 + BA
CB / CA = DE / DF
6/(6 + BA) = 4/11
6 × 11 = 4(6 + BA)
66 = 24 + 4BA
24 + 4BA = 66
4BA = 66 - 24
4BA = 42
BA = 42/4

PLEASE HELP ASAP !! The flight of Jae and Miguel's rocket t seconds after launch is modeled by
h(t) = -5t² + 40t + 1, where h(t) is their rocket's height in meters.
What was their rocket's height in meters 0.5 seconds after launch???How many sec after launch did their rocket hit the ground???What was their rockets maximum height in meters??
The height in meters is 19.75 meters
The rocket hit the ground after 8.06 sec
The maximum height in seconds is 81 meters
What was their rocket's height in meters 0.5 seconds after launchwe would have to use 0.5 as the value for t in the formula
h(t) = -5t² + 40t + 1
h(0.5) = -5(0.5)² + 40(0.5) + 1
= -1.25 + 20 +1
= 19.75
How many sec after launch did their rocket hit the ground?To find when the rocket hit the ground, we need to find when the height of the rocket is equal to 0. So we will set h(t) = 0 and solve for t:
-5t² + 40t + 1 = 0
by using Quadratic equation formula we get t = (-b ± √(b²-4ac))/2a
we solve this using the calculator
so t1 = (40 + 40.6)/10 = 80.6/10 = 8.06 sec
Since the time of the rocket hit the ground should be positive, so the rocket hit the ground after 8.06 seconds after launch.
What was their rockets maximum height in meters?To find the rocket's maximum height, we need to find the vertex of the parabola. The vertex of the parabola can be found by using the formula x = -b/2a,
where x is time and a, b, c are from equation.
so, x = -b/2a
= -40/2*-5
= -40/ -10
= 4 sec
and by using the above formula of x, we get the
h(4) = -5(4)² + 40(4) + 1
= -80 + 160 + 1
= 81 meters
Therefore, the rocket's maximum height is 81 meters.
