Answer:
The above answers are incorrect.
Step-by-step explanation:
If the price of one of the goods decreases, the quantity demanded of that good will increase due to the substitution effect. This means that the consumer will choose to buy more of the cheaper good and less of the more expensive good. The income effect may also come into play, as the consumer now has more disposable income due to the lower price of one of the goods. However, it is not possible to determine the exact quantity of each good that the consumer will purchase without further information.
In this case, if the price of one of the goods decreases from $10 to $8, the consumer will likely purchase more of that good and less of the other good, which is a substitution effect. The income effect may also come into play, as the consumer now has more disposable income due to the lower price of one of the goods. However, it is not possible to determine the exact quantity of each good that the consumer will purchase without further information.
Therefore, the correct answer is e. The above answers are incorrect.

Phishing is when a hacker impersonating a reliable entity sends you a phony email in the hopes that you will voluntarily divulge your personal information.
What is phishing?Phishing is a type of social engineering in which an attacker sends a false (for example, spoofed, phony, or other deceptive) communication with the goal of tricking a person into providing the attacker with vital information[1] or to install harmful software, such as ransomware, on the victim's infrastructure.
Phishing attacks are becoming more and more sophisticated, and they frequently transparently mirror the site that is being attacked, allowing the attacker to see everything the victim does there and to get past any further security measures with them.
[] According to the FBI's Internet Crime Complaint Center, which tracks more phishing incidents than any other type of computer crime combined, phishing attacks will be by far the most common type of hacker attack through 2020. []
For the first time, the term "phishing" was employed.
Hence, Phishing is when a hacker impersonating a reliable entity sends you a phony email in the hopes that you will voluntarily divulge your personal information.

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

What is sum of angles of a triangle?
A triangle's total angles equal the straight angle (180 degrees, radians, two right angles, or a half-turn) in a Euclidean space. Three angles, one at each vertex and bounded by two neighbouring sides, make up a triangle.
For a very long period, it was unknown if there were any alternative geometries for which the total is different. During the 19th century, this issue had a particularly significant impact on mathematics. Ultimately, it was determined that the response was correct: in other geometries, this total can be higher or smaller, but it must then depend on the triangle. Its deviation from 180° represents an instance of an angular defect and is a crucial distinction for geometric systems.
From the fig.
we know,
e=37
b= 143 (vertically opposite angle)
143 + a = 180 (Linear pair)
a = 180 - 143
a = 37
e = 37
So, c = 37 (Vertically opposite angle)
c + d + 85 = 180 (Sum of angles on straight line)
37 + d + 85 = 180
d = 180 - 122
d = 58
e + 90 + f = 180 (Sum of all angles of a triangle)
37 + 90 + f = 180
f = 180 - 127
f = 53
g = 48 (if two sides are equal , then the two angles opposite to the equal
sides will also be equal.)
48 + 48 + h = 180 (Sum of angles of a triangle)
h = 180 - 96
h = 94
h+ k = 180 (Linear pair)
94 + k = 180
k = 180 - 94
k = 96
d + k + m = 180 (Sum of angles of a triangle)
58 + 96 + m = 180
m = 180 - 154
m = 26
26 + 85 + p = 180 (Sum of angles of a triangle)
p = 180 - 111
p = 69
p + r = 180 (Linear pair)
r = 180 - 69
r = 111
p = s (corresponding angles)
s = 69
Hence all angles are:
a = 37
b = 143
c = 37
d = 58
e = 37
f = 53
g = 48
h = 94
k = 96

f f(x)=tan(2x), what is the absolute difference between f(5.4) and T2(5.4), if the second degree Taylor polynomial is centered at x = 5?
Round your answer to 3 places.
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]
|f(5.4) - T2(5.4)| ≈ 2.674

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.
in an isosceles triangle the perimeter is 8 more than two times one of the legs if the perimeter is 28 find the length of the base
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

How to determine the solution to the matrix equations?From the question, we have the following parameters that can be used in our computation:
(a) 2X=(-4 0 8)(b) 3 X-(1 7)=(-16 -4)Solving matrix A, we have the following representations
2X=(-4 0 8)
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)

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

What is the equation of a line?
An algebraic way to represent a collection of points that together make a line in a coordinate system is called the equation of a line. An algebraic equation, commonly known as the equation of a line, can be created using the various points that together make up a line in the coordinate axis as a collection of variables (x, y). It is possible to determine whether a specific point lies on a line by utilising the equation of a line.

Given, two points are (-3,-15/2) and(1,-3/2).
[tex](x_{1} ,y_{1} )[/tex] = (-3,-15/2) and [tex](x_{2},y_{2})[/tex] = (1,-3/2).
So, The equation of line passing through (-3,-15/2) and (1,-3/2) is given by
or, [tex]\frac{y+\frac{15}{2} }{x+3 } = \frac{-\frac{3}{2} +\frac{15}{2} }{1 +3 }[/tex]

[tex]\begin{array}{ccll} \$&hours\\ \cline{1-2} 44 & 6\\ x& 9 \end{array} \implies \cfrac{44}{x}~~=~~\cfrac{6}{9} \\\\\\ \cfrac{ 44 }{ x } ~~=~~ \cfrac{ 2 }{ 3 }\implies 132=2x\implies \cfrac{132}{2}=x\implies 66=x[/tex]
