Step-by-step explanation:
The projected number of people aged 65 and over in the U.S. population with Alzheimer's disease (in millions) is given byP(t) = −0.0002083t 3 + 0.0157t 2 – 0.093t + 5.2 (4 ≤ t ≤ 40);Where t is measured in years and t = 4 corresponds to the year 2014. This model does not claim validity for years 2051 and beyond. Nevertheless, the model does suggest that:
The missing part of the question is;
What is the projected number of people aged 65 and over with Alzheimer's disease in 2030 and in 2050
Answer:
In 2030, P(20) = 7.9536 (in millions)
In 2050, P(40) = 13.2688 (in millions)
Step-by-step explanation:
We are given that;
Number of people aged 65 and over in the U.S. population with Alzheimer's disease (in millions) as;
P(t) = −0.0002083t³ + 0.0157t² – 0.093t + 5.2 (4 ≤ t ≤ 40);
Where t is measured in years and t = 4 corresponds to the year 2014.
Now,
Since t = 4 represents 2014,therefore;
t = 20 would represent population in 2030
Thus in year 2030;
P(20) = −0.0002083(20)³ + 0.0157(20)² – 0.093(20) + 5.2
P(20) = 7.9536 (in millions)
Also, in year 2050, t will correspond to 40 years.
Thus;
P(40) = −0.0002083(40)³ + 0.0157(40)² – 0.093(40) + 5.2
P(40) = 13.2688 (in millions)

Find the general solution of the homogeneous system below. Give your answer as a vector.
x1 + 2x2 - 3x3 = 0
4x1 + 7x2 - 9x3 = 0
-x1 - 3x2 + 6x3 = 0
Answer:
Step-by-step explanation:
Given the system of homogeneous equations
x1 + 2x2 - 3x3 = 0 ................. 1
4x1 + 7x2 - 9x3 = 0 ................... 2
-x1 - 3x2 + 6x3 = 0..................... 3
First we will reduce the equation to two equations and two unknowns;
add equation 1 and 3;
2x2-3x2 +(-3x3+6x3) = 0
-x2 + 3x3 = 0
x2 = 3x3 .......... 4
Multiply equation 3 by 4 and add to equation 2;
equation 3 * 4 will give;
-4x1 - 12x2 + 24x3 = 0..................... 5
add equation 5 to equation 2;
7x2-12x2-9x3+24x3 = 0
-5x2 - 15x3 = 0 .......... 6
5x2 = 15x3
x2 = 3x3
Let x2 = k
From equation 4;
k = 3x3
x3 = k/3
substitute x2 = k and x3 = k/3 into equation 1 to get x1 in terms of k
From 1, x1 + 2x2 - 3x3 = 0
x1+2k-3(k/3) = 0
x1 +2k-k = 0
x1 +k = 0
x1 = -k
Writing the answer in vector form will give (x1. x2. x3) = (-k, k, k/3)
k(-1, 1, 1/3)
Hence the answer to the system of equation in vector form is k(-1, 1, 1/3) where k is any constant.

solve for x, UV and TV
We know that TV = TU + UV. Let's plug the values from the picture into our equation.
x + 25 = 9 + 2x + 28.
Let's combine like terms on the right side.
x + 25 = 2x + 37
Subtract 37 and x from both sides.
-12 = x
TV = x + 25 = -12 + 25 = 13
UV = 2x + 28 = 2(-12) + 28 = -24 + 28 = 4

If the revenue function for a particular commodity is R(p) = −53p2 + 64p, what is the (linear) demand function q(p)?
The Demand Function would be as follows:
[tex]Q = 64 - 53p[/tex]
What is Demand Function?This shows the relationship between Price & Quantity, represents Quantity as a function of price.
Revenue is the total receipts from sale, with the formula [tex]= Price[/tex] × [tex]Quantity[/tex]
So,
[tex]Quantity = Revenue / Price[/tex]
Hence, dividing the given revenue equation by P, we get
[tex]Q = (- 53p^2 + 64p )[/tex][tex]/ pQ = - 53p + 64[/tex] {Demand Function}
So, above-mentioned [tex]Q = 64 - 53p[/tex] is the Demand Function.

1). Use the same ratio as 16 people in 25 square feet to estimate the size of a
crowd that is 10 feet deep on both sides of the street standing along a 1-mile
section of a parade route.
Answer:
33,792 people
Step-by-step explanation:
The parade route is rectangular in nature. The area of the parade route will be expressed as:
Area = Length × Breadth
If the route is 10feet deep, the length of the route = 10feet
Is the section of the route is 1 mile, the width of the parade route = 1mile × 5280ft = 5280ft
Area of the parade route = 10×5280 = 52,800ft²
If 16 people in 25 square feet is used to estimate the size of a crowd, the number of a crowd in a 52800ft² parade route is expressed as;
25ft² = 16
52800ft² = x
Cross multiply
25×x = 16×52800
25x = 844,800
x = 844,800/25
x = 33,792
Hence there are 33,792 people on 1-mile section of a parade route that is 10ft deep.

7. Write the equation of the line that passes through the
point P (0,0), and is parallel to the line y = 7x - 8. Write
the answer in slope-intercept form.
Answer: y=7x
Step-by-step explanation:
To find the line that is parallel to the given line, we know that the slope will stay the same. Parallel lines NEVER touch or cross. Therefore, the slope MUST stay the same. All we have to do is plug in the given point to find the y-intercept.
y=7x+b
0=7(0)+b [multiply]
b=0
Now, we know the equation is y=7x+0 or y=7x.

The lesser milk the mother had made her chocolate more chocolatery, and you can see that she has a 0.2 more than the father
Answer:
The correct answer is Nell's mom.
Step-by-step explanation:
Nell's mom makes chocolate syrup with 30 ml for every chocolate syrup for every 2 ounces of milk.
Nell's dad adds 65 ml of chocolate syrup for every 5 ounces of milk.
To compare who makes a more chocolaty drink we need to have same amount of milk.
Least common multiple of 2 and 5 is given by 10.
Thus in 10 ounces of milk, Nell's mom adds 30 × 5 = 150 ml of chocolate syrup.
In 10 ounces of milk, Nell's dad adds 65 × 2 = 130 ml of chocolate syrup.
Thus on comparison we can say Nell's mom adds more chocolate syrup and hence makes a more chocolaty milk.
