The given function are
r(x) = 2 - x² and w(x) = x - 2
(w*r)(x) can be obtained by multiplying the both function together
So, (w*r)(x) = w(x) * r(x) = (x-2)*(2-x²)
(w*r)(x) = x (2-x²) - 2(2-x²)
= 2x - x³ - 4 + 2x²
∴ (w*r)(x) = -x³ + 2x² + 2x - 4
It is a polynomial function with a domain equal to R
The range of (w*r)(x) can be obtained by graphing the function
To graph (w*r)(x), we need to make a table between x and (w*r)(x)
See the attached figure which represents the table and the graph of (w*r)(x)
As shown in the graph the range of (w*r)(x) is (-∞,∞)
In triangle OPQ, o=700 cm, p=840 cm and q=620. Find the meaure of ide P to the nearet degree
The measure of side P to the nearest degree is 79 degrees.
Given:
ΔOPQ ,
O = 700 cm,
P = 840cm
Q = 620cm.
To find:
The measure of angle P.
According to the Law of Cosines:
In trigonometry, the law of cosines relates the lengths of the sides of a triangle to the cosine of one of its angles. The law of cosines states:
[tex]cos A = b^{2} +c^{2} - a^{2} / 2bc[/tex]
Using Law of Cosines ΔOPQ, we get,
cos P = o² +q²- p² / 2oq
⇒ cos P = (700)² + (620)² -(840)² /2×700×620
⇒ Cos P = 490000 + 384400 - 705600 / 868000
⇒ Cos P = 168800/868000
on further simplification, we get,
Cos P = 0.19447
P = Cos⁻¹ (0.19447)
P = 78.786236
P = 79.
∴ the measure of angle P is 79 degrees.

fifth degree, 4 is a zero of multiplicity 2, −4 is the only other zero, leading coefficient is 2.
The equation of the polynomial equation with a fifth degree is P(x) = (x + 4)³(x - 4)²
How to determine the polynomial equation?The given parameters are
Degree of polynomial = 54 is a zero of multiplicity 2-4 is the only other zeroThe sum of multiplicities of the polynomial equation must be equal to the degree.
This means that the multiplicity of the zero -4 is 3
The equation of the polynomial is then calculated as
P(x) = (x - zero)^multiplicity
Substitute the known values in the above equation, so, we have the following representation
P(x) = (x - (-4))³ * (x - 4)²
Open the inner brackets
P(x) = (x + 4)³ * (x - 4)²
This gives
P(x) = (x + 4)³(x - 4)²
Hence, the equation is P(x) = (x + 4)³(x - 4)²

Step-by-step explanation:
Look at the table below what’s the value of k
Answer:
k = 5
Step-by-step explanation:
substitute the values of x into 3x + k and equate with the corresponding value, that is
x = 1
3(1) + k = 8
3 + k = 8 ( subtract 3 from both sides )
k = 5
x = 3
3(3) + k = 14
9 + k = 14 ( subtract 9 from both sides )
k = 5
x = 5
3(5) + k = 20
15 + k = 20 ( subtract 15 from both sides )
k = 5
the value of k is therefore 5

Given;
The expected return on security x is 9%, whereas the standard deviation is 18%. The expected return on security y is 12%, and the standard deviation is 21%. If the correlation between the two securities is 0.4
Security X:
Expected return E(Rx) = 9% = 0.09
Standard deviation (σx) = 18% = 0.18
Security Y:
Expected return E(Ry) = 12% = 0.12
Standard deviation (σy) = 21% = 0.21
and
Corr(X,Y) = -0.4
We know that,
Corr(X,Y) = Cov(X,Y)/ σx*σy
Substituting the above-given values, we get;
-0.4 = Cov(X,Y)/ 0.18*0.21
-0.4 = Cov(X,Y)/ 0.0378

Which equation represents the line that passes through point (2,3) and is perpendicular to 4x-5y=7
Answer:
Step-by-step explanation:
First, find the slope of 4x - 5y = 7
Simplify it down to a readable form:
5y = 4x - 7
y = (4x - 7)/5
y = 4/5 x - 7/5
slope = 4/5
slope perpendicular to 4/5 is its opposite reciprocal, which would be -5/4.
given the point (2,3), we can get the equation using point slope form for linear equations: y-k = m(x-h) for point (h,k).
now plug:
y-3 = (4/5)(x-2)
y-3 = (4/5)x - 8/5

The arithmetic sequence that has the given features is presented as follows:
[tex]a_n = 2 + 3(n - 1)[/tex]
What is an arithmetic sequence?An arithmetic sequence is a sequence of values in which the difference between consecutive terms is constant and called common difference d.
The nth term of an arithmetic sequence is obtained by the following rule:
[tex]a_n = a_1 + (n - 1)d[/tex]
In which [tex]a_1[/tex] is the first term of the sequence.
The sum of the first n terms is presented as follows:
[tex]S_n = \frac{n(a_1 + a_n)}{2}[/tex]
The sum of the first nine terms is of 126, hence:
[tex]S_9 = 126[/tex]
[tex]\frac{9(a_1 + a_9)}{2} = 126[/tex]
[tex]4.5(a_1 + a_9) = 126[/tex]
The ninth term is written as follows:
[tex]a_9 = a_1 + 8d[/tex]
Hence:
[tex]4.5(a_1 + a_1 + 8d) = 126[/tex]
[tex]9a_1 + 36d = 126[/tex]
[tex]a_1 + 4d = 14[/tex]
The sum of the second nine terms is of 369, hence:
[tex]S_{18} = 126 + 369[/tex]
[tex]S_{18} = 495[/tex]
Then:
[tex]\frac{18(a_1 + a_{18})}{2} = 495[/tex]
[tex]a_{1} + a_{18} = 55[/tex]
The 18th term is:
[tex]a_{18} = a_1 + 17d[/tex]
Hence:
[tex]2a_1 + 17d = 55[/tex]
From the first equation, it is found that:
[tex]a_1 = 14 - 4d[/tex]
Hence the common difference is obtained as follows:
2(14 - 4d) + 17d = 55
28 - 8d + 17d = 55
9d = 27
d = 3.
Hence the first term is of:

The sum of the measures of the exterior angles of a triangle, one at each vertex, is 360° and it proved.
Exterior angle
The the angle that is formed with one side and the adjacent extended side of a triangle is known as exterior angle.
Given,
Here we use linear pairs to find the sum of all the angles labeled in the triangle.
And then use what you know about the interior angles of a triangle to show that the sum of the measures of the exterior angles of a triangle, one at each vertex, is 360°.
While we looking into the following figure, we can see that R and Y are the interior and exterior angles of the triangle respectively.
Therefore, here the angles Y and R form a linear pair.
So, we can written it as,
=> Y + R = 180°
Then the value of y is
=> Y = 180° - R
Therefore, when we calculate the value of the full triangle, then we get
=> (Y + R) + (Y + R) + (Y + R) = 180° + 180° + 180°
When we simplify this one,
=> 3Y + 3R = 540° --------- (1)
We already know that, the sum of interior angles of the triangle is as follows,
=> R + R + R = 180°
By using angle sum property of a triangle,
WE can written this like the following,
=> 3R = 180° --------- (2)
Now, substituting the value from equation(2) in equation(1) we get,
Then,
=> 3Y + 180° = 540°
=> 3Y = 540° - 180°
=> 3Y = 360°
Therefore, the sum of exterior angles = 360°

How to determine the measure of each missing angle?
To solve this problem, we need some angle geometry knowledge:
Since the sum of angles on a straight is 180°. Thus:
m<1 + 82° + 58° = 180°
m<1 = 180° -82° - 58° = 40°
The sum of angles on a triangle is 180°:
m<2 + 58° + 61° = 180°
m<2 = 180° - 58° - 61° = 61°
m<2 + m<3 = 180° (angles on a straight )
61°+ m<3 = 180°
m<3 = 180°-61° = 119°
m<4 = m<2 = 61° (alternate angles)
m<5 + m<4 + 61 = 180° (angles on a straight )
m<5 + 61° + 61 = 180°
m<5 = 180°- 61°-61° = 58°
m<5 + m<6 = 180° (angles on a straight )
58°+ m<6 = 180°
m<6 = 180°-58° = 122°
m<7 = 58° (alternate angles)
m<1 + m<7 +m<8 = 180° (angles on a triangle )
40+58°+m<8 = 180°
m<8 = 180°-40-58° = 82°
m<8+m<9 = 180° (angles on a straight )
82+m<9 = 180°
m<9 = 180°-82° = 98°
The measure of the missing angles m<1, m<2, m<3, m<4, m<5°, m<6, m<7, m<8 and m<9 are 40°, 61°, 119°, 61°, 58°, 122°, 58°, 82° and 98° respectively

5. 100x=17.1717……
To write our number as a fraction, the order of the steps is:
step 3.step 5.step 4.step 2.step 1.How to write the repeating decimal as a fraction?First, we define our number:
x = 0.1717...
So we start with the step 3.
Now notice that there are two repeating decimals, so we need to multiply both sides by 100 (as many zeros as repeating decimals)
100*x = 10*0.1717... = 17.1717...
This is step 5.
Now we can subtract the original number in both sides so we remove the repeating decimals:
100*x - 0.1717... = 17.1717... - 0.1717...
99*x = 17
These are steps 4 and 2.
Finally, we divide both sides by 99 to get:
x = 17/99
Which is step 1.
And that is our number written as a fraction.

By using the equation of the line and the perpendicular line relationship, the equation of the perpendicular line y = (8 / 3) · x - 5
How to determine the equation of a line perpendicular to another line
Mathematically speaking, lines are represented by equations of the form:
y = m · x + b
Where:
x - Independent variabley - Dependent variablem - Slopeb - y-InterceptAnd two lines perpendicular to each other observe the following relationship:
m · m' = - 1
Where:
m - Slope of the original line.m' - Slope of the perpendicular line.First, determine the slope of the perpendicular line by perpendicular line relationship:
m = - 3 / 8
m' = - 1 / (- 3 / 8)
m' = 8 / 3
Second, calculate the intercept of perpendicular line by the equation of the line:
b = y - m · x
b = 3 - (8 / 3) · 3
b = 3 - 8
b = - 5
Third, write the equation of the perpendicular line:
y = (8 / 3) · x - 5

Find the equation of a line perpendicular to y= 4/3 x−1 that passes through the point (-4,-8)(−4,−8).
4y = -3x-12 the equation of a line perpendicular to y= 4/3 x−1 that passes through the point (-4,-8).
How do you find the equation of a line parallel or perpendicular?A straight line's general equation is y = mx + c, where m is the gradient and y = c is the value at which the line intersects the y-axis.
The slope of parallel lines is the same. The slopes of perpendicular lines are opposing reciprocals. To put it another way, if m=a/b, then m⊥= -b/a.
y= 4/3 x - 1
Slope = 4/3
Equation of line perpendicular to this line
y= -( 3/4) x+b
As slope is -1/m
Now as line passes through (-4,-8)
Plug it in
-8 = (-3/4)(-4) +b
-8= 3+ b
Gives b = -12
So the equation of line will be
y = (-3/4) x -12
or 4y = -3x-12

I'm in desperate need on how to solve
Answer:
x = 5; m<1 = 69
Step-by-step explanation:
We know that the two angles with degrees 20x+11 and 25x-14 are vertical angles and are thus congruent or equal. Therefore, we can set the two angles equal to each other to find x:
[tex]20x+11=25x-14\\20x+25=25x\\25=5x\\5=x[/tex]
If we plug in x into any of the two angles, we find the measure of both angles is 111.
The most probable relationship between angle 1 and the other two angles is supplementary, which means that the measure of angle 1 and any of the two angles beside it is 180.
To find m<1, represented as x, we can use the equation:
[tex]180=20(5)+11+x\\180=111+x\\69=x[/tex]
