What are Functions?

A function from a set X to a set Y allocates precisely one element of Y to each element of X. The set X is termed the domain of the function and the set Y is called the codomain of the function.

The function is H(d) = 16 + 1.5d

Since, all the options talks aabout the height of the plant after 22 days

We need to put the value of d as 22 in the function for calculating the height of the function

H(22) = 16 + 1.5(22)

H(22) = 16 + 33 = 49

According to the given consumer price index, President Hoover's 1931 salary is equivalent to what amount in 2005 is $962,250

Consumer price index:

In math, the concept of consumer price index (CPI) is significant in the analysis of inflation.

The general form of CPI of current years is computed as

=> (GDP of current period / GDP of base period) x 100.

Given,

In 1931, President Herbert Hoover was paid a salary of $75,000. Government statistics show a consumer price index of 15.2 for 1931 and 195 for 2005.

Here we need to find the President Hoover's 1931 salary is equivalent to what amount in 2005.

Here we have the values of

=> CPI = 15.2 in 1931,

=> salary 75000;

=> CPI = 195 in 2005,

Then the salary is calculated as,

=> 75000 x (195/15.2)

=> 75000 x 12.83

=> 962250

The 125 is the median number of calories per serving for the breakfast cereals.

What is median?

The middle value in a sorted, ascending or descending list of numbers is known as the median, and it has the potential to describe a data set more accurately than the average does. It represents the midpoint of the data because it is the point above and below which half (50%) of the observed data falls.

Given:

The box-and-whisker plot below shows the distribution of the numbers of calories per serving for a selection of breakfast cereals.

We have to find the median.

Since median is the middle most number of the given list of numbers.

In the given list there are 11 numbers.

The middle most number is occur at 5th number.

The number on 5th place is 125.

The pressure of 28 inches of mercury occurs about 6 miles from the eye of the hurricane. We get this from the given algebraic expression.

An expression is formed by variables, constants, and algebraic operations. Since the operation among them is an algebraic or arithmetic operation, it is said to be an algebraic expression.

It is given that the algebraic expression that relates the barometric pressure and the eye of the hurricane as

f(x) = 0.48 ln(x+2) + 27

Here x is the distance in miles from the eye of the hurricane.

f(x) is the pressure of the mercury in a barometer in inches

So, the required distance from the eye of the hurricane when the pressure of 28 inches of mercury in the meter is

(Here f(x) = 28)

f(x) = 0.48 ln(x+2) + 27

⇒ 28 = 0.48 ln(x+2) + 27

⇒ 0.48 ln(x+2) = 28 - 27

⇒ ln (x+2) = 1/0.48

⇒ ln(x+2) = 2.0833

Applying exponential base "e" on both sides, we get

(x+2) = [tex]e^{2.0833}[/tex]

⇒ x + 2 = 8.0309

⇒ x = 8.0309 - 2 = 6.0309

When the result is rounded to the nearest whole number, we get x = 6 miles.

Thus, for the pressure of 28 inches of mercury, the eye of the hurricane is 6 miles far from the barometer.

A graph with three zeros, one of which is at x = 4, will resemble the one below.

A polynomial function is a function in an equation, such as the quadratic equation, cubic equation, etc., that only uses non-negative integer powers or only positive integer exponents of a variable. A polynomial with an exponent of 1 is, for instance, 2x+5.

Minimum and Maximum?

The extrema of a function are known as its maximum and minimum. The highest and smallest values of a function within the predetermined set of ranges are known as maxima and minima. The largest value of the function under the full range is referred to as the absolute maxima, while the least value is referred to as the absolute minima.

If the function has three zeros with one relative maximum and one relative minimum, it could be a cubic equation.

If it has a factor of x - 4, the graph crosses the x-axis at (4,0).

Answer:

base = 8

Step-by-step explanation:

In an isosceles triangle, the legs are equal.

P = 28 = 2L + 8

2L + 8 = 28

2L = 20

L = 20/2 = 10 (length of each leg)

P = 2L + b  (sum of the lengths of the 2 legs and the base)

28 = 2(10) + b

b = 28 - 20 = 8

k(n) is also the number of partitions of n into distinct, odd parts. We begin with the generating function P(x) = ∑p(n) x_n which counts all partitions of all numbers n, with weight x_n for a partition of n.

How do you explain partitioning numbers?

By breaking huge numbers into smaller parts, partitioning helps to simplify the solution of arithmetic issues involving large numbers. 782, for instance, may be divided into: 700 + 80 + 2. It aids children in understanding the real value of each digit. They will perceive 782 as 700, 80, and 2, rather than as a terrifying number.

The numbers of partitions of 10 with number of parts {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} are respectively {1, 5, 8, 9, 7, 5, 3, 2, 1, 1}. (There are 20 partitions of 10 into an odd number of parts and 22 partitions of 10 into an even number of parts.)

Transformation involves changing the form of a function. The transformations are:

vertical translation 1 unit up .

horizontal translation 5 units left.

The functions are given as:

f(x) = 8x

g(x) = [tex]8^{x+5}[/tex] + 1

Start by translating the function 5 units left.

The rule of this translation is:

f'(x) = f(x+5)

So, we have:

f'(x) = 8(x+5)

Next, translate the function 1 unit up

The rule of this translation is:

f"(x) = f'(x) + 1

∴ f"(x) = 8(x+5) + 1

Rewrite as:

g(x) = 8(x+5) + 1

The absolute difference rounded to three decimal places is 2.674.

What is polynomial?

An expression that consists of variables, constants, and exponents and is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.

Given: f(x) = tan(2x)

Then f(5.4) = tan(2 x 5.4) = tan(10.8) = tan(54/5)

The second degree Taylor polynomial centered at x =  5 is given by,

T2(x) = Σ(n = 0, 2) f^n(5)/5!(x - 5)^n

Now,

f°(x) = f(x) = tan(2x)

f(5) = tan(2 x 5) = tan(10)

f'(x) = d/dx(tan(2x))

f'(x) = 2 sec^2x = 2( 1 + tan^2(x))

f'(5) = 2(1 + tan^2(10))

f"(x) = d/dx[2(1 + tan^2(2x)]

f"(x) = 0 + 2(2tan(2x)(2sec^2(2x))

f"(x) = 8 tan(2x)(1 + tan^2(2x))

f"(5) = 8 tan(10)(1 + tan^2(10)

Then

[tex]T_2(x) = \frac{tan(10)}{0!}(x - 5)^0 + \frac{2 + 2tan^210}{1!}(x - 5)^1 + \frac{8(tan(10)(1+tan^2(10)}{2!}(x - 5)^2 \\T_2(5.4) = tan(10) + 2(1 + tan^2(10)) (5.4 - 9) +4tan(10)(1 + tan^2(10)(5.4 - 5)^2\\T_2(5.4) = \frac{16}{25} tan^310 + \frac{4}{5}tan^2(10) + \frac{41}{25} tan(10) + \frac{4}{5}[/tex]

The absolute difference is,

[tex]|f(5.4) - T_2(5.4)| = 2.673745[/tex]

The probability that a student passes both the tests is 0.5896.

The conditional probability deals with dependent events. In order to evaluate it, Bayes' theorem is applied which can be written as P(B|A) = P(A ∩ B)/P(A), where B|A denotes the event of occurring B when A has already happened and A ∩ B denotes the occurring of both events simultaneously.

The given problem can be solved as follows,

Suppose A be the event a student passes French 101 and B be the event that he passes French 102.

Then, as per the question the probabilities are given as,

P(A) = 0.67,

And, P(B|A) = 0.88.

Suppose, A ∩ B be the event a student passes both tests.

Apply Bayes' theorem to obtain,

P(B|A) = P(A ∩ B)/P(A)

Substitute the corresponding values in the above expression.

0.88 = P(A ∩ B)/0.67

=> P(A ∩ B) = 0.88 × 0.67

=>  P(A ∩ B) = 0.5896

Step-by-step explanation:

a.

correct, the population was 18.5 million in 2000.

why ?

t = years after 2000.

so, if the year is 2000, t = 0.

A(0) = 18.5e^(0.1708 × 0)

you remember, a⁰ = 1 for any a.

so,

A(0) = 18.5×e⁰ = 18.5×1 = 18.5 million.

b.

we need to find the value of t for which A(t) = 26.6.

26.6 = 18.5e^(0.1708 × t)

26.6/18.5 = e^(0.1708 × t)

ln(26.6/18.5) = 0.1708 × t

t = ln(26.6/18.5)/0.1708 = 2.126115244... years

≈ 2 years

2 years after 2000 is 2002.

it will reach 26.6 million in the year 2002.

The solution to the matrix equations A and B are X = (-2 0 4) and X = (-5 1)

From the question, we have the following parameters that can be used in our computation:

Solving matrix A, we have the following representations

Rewrite the equation properly

So, we have

2X = (-4 0 8)

Divide through the matrix by 2

This gives

X = (-2 0 4)

Solving matrix B, we have the following representations

3 X-(1 7)=(-16 -4)

Rewrite the equation properly

So, we have

3X - (1 7) = (-16 -4)

Add (1 7) to both sides of the equation

This gives

3X = (-15 3)

Divide through the matrix by 3

This gives
