Diseases tend to spread according to the exponential growth model. In the early days of AIDS, the growth multiplier (i.e. common ratio) was around 2.0. In 1983, about 1800 people in the U.S. died of AIDS. We can use the exponential model:
P
n
=
1800
(
2.0
n
)
.
If the trend had continued unchecked, how many people would have died from AIDS in 2004?
If the trend had continued unchecked, 3,774,873,600 people would have died from AIDS in 2004
How many people would have died from AIDS in 2004?The equation of the function is given as
P(n) = 1800(2.0)^n
Where n represents the number of years since 1983
There are 21 years from 1983 to 2004
This is calculated as
n = 2004 - 1983
n = 21
Substitute 21 for n in the equation P(n) = 1800(2.0)^n
So, we have
P(21) = 1800(2.0)^21
Evaluate
P(21) = 3774873600
Hence, if the trend had continued unchecked, 3,774,873,600 people would have died from AIDS in 2004

According to the following table, what is the federal income tax due for Mr. and Mrs. Jones filing their federal income tax return jointly who make a combined $92,400 in taxable income?
Based on the fact that Mr. and Mrs. Jones are filling their federal tax return jointly, their federal income tax due is $11,737
How to find the federal income tax?There was no table included so I will use the federal income tax rates for those filing in April 2022.
For a married couple filing jointly like Mr. and Mrs. Jones with a combined $92,400 taxable income, the federal income tax due is:
= 9,328 + 22% of income over $81,050
= 9,328 + (22% x (92,000 - 81,050))
= 9,328 + (22% x 10,950))

Special Angle Pairs
Find m<1
Please help !
Special Angle Pairs, m<1, then the expression is,
(4x + 16)° = (2x + 34)° = 52° where, x = 9°
⇒ As shown in Graph,
⇒ (4x + 16)° is congruent to (2x + 34)°
⇒ Because they are vertical angles.
The angles opposite each other when two lines cross. They are always equal. In this example a° and b° are vertical angles. "Vertical" refers to the vertex (where they cross), NOT up/down.
These are vertical angles.
So,
We can write,
(4x + 16)° = (2x + 34)°
Calculate the equation,
(4x - 2x)° = (34 - 16)°
We can use sum or difference,
(2x)° = (18)°
We can divide the values,
(x)° = (18/2)°
x° = 9°
Hence,
x° = 9°
We can substitute x = 9° value in (4x + 16)° and (2x + 34)° expression,
So,
We can use,
= (4x + 16)°
= (4*9 + 16)°
= (36 + 16)°
= 52°
Therefore,
(4x + 16)° = 52°
We can use,
= (2x + 34)°
= (2*9 + 34)°
= (18 + 34)°
= 52°
Therefore,
(2x + 34)° = 52°
Hence,
Special Angle Pairs, m<1, then the expression is,
(4x + 16)° = (2x + 34)° = 52° where, x = 9°

What is the 99th digit of pie?
The approximation of pi to 99 decimal places is 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679.
We have,
Determining the 99th digit of pi requires an understanding of the properties of pi and how it is calculated.
Pi is an irrational number, which means it has an infinite number of non-repeating decimal digits.
Since pi has an infinite number of digits, it is not possible to directly state the 99th digit without extensive computation.
However, various methods and algorithms have been developed to approximate the value of pi to a specific number of decimal places.
The 99th digit of pi has not been explicitly determined.
Thus,
The approximation of pi to 99 decimal places is 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679.

The ratio of the point C on the line segment is 2 : 3
How to determine the ratio of the point C on the line segment?The line segment that completes the question is added as an attachment
On the attached line segment, we have the following points assuming that the point A is at A = 0
So, we have
A = 0
C = 2
B = 5
The above means that
AB : CB = C - A : B - C
So, we have
AB : CB = 2 - 0 : 5 - 2
Evaluate the difference
AB : CB = 2 : 3
Hence, the ratio of the point C on the line segment is 2 : 3

far is Maurice from his starting point?
miles
Maurice is a distance of 232 miles away from his starting point.
What is the final distance of Maurice from his starting point by using vectors and Pythagorean theorem?
Let suppose the existence of a coordinate system whose orthogonal axes are represented by north and east directions, which means that both north and east directions have positive signs. Then, the vector position of Maurice relative to his starting point is:
r = ∑ Δx i + ∑ Δy j
Where:
Δx - Net change in the east direction.Δy - Net change in the north direction.Then, the vector position of Maurice relative to his starting point is:
r = (- 168) i + (- 262 + 422) j
r = - 168 i + 160 j
And the distance is found by using the Pythagorean theorem:
r = √[(Δx)² + (Δy)²]
r = √[(- 168)² + 160²]
r = 232

When traveling to Great Britain, Bethany exchanged $635 US dollars into £580 British pounds. How many pounds did she receive for each US dollar?
After the exchange from the U.S dollar to British pounds, Bethany received £0.91 for each U.S. dollar.
What is an exchange rate?An exchange rate is a rate or a price of one country's currency in terms of another.
The exchange rate describes how much each currency can be obtained when converting one currency to another.
In this instance, the exchange rate between the U.S. dollar and the British pound is $1 = £0.91.
Data and Calculations:Total US dollars with Bethany = $635
The total British pounds received by Bethany after the exchange = £580
Exchange rate per U.S. dollar = £0.91 (£580/$635)
Exchange rate per British pound = $1.095 ($635/£580)
Thus, Bethany received £0.91 for each U.S. dollar.
