Write an expression in factored form for the polynomial of least possible degree graphed below.
The expression in factored form for the polynomial of least possible degree graphed will be y(x) = (x + 3)(x + 2 )(x - 1 )(x - 3 )
How to factor the polynomial?From the graph, the zeros of the polynomial of given graph are:
x = -3
x = -2
x = 1
x = 3
Equate the above equations to zero
x + 3 = 0
x + 2 = 0
x - 1 = 0
x - 3 = 0
Multiply the equations
(x + 3)(x + 2 )(x - 1 )(x - 3 ) = 0
Express as a function gives;
y = (x + 3)(x + 2 )(x - 1 )(x - 3 )
Hence, the factored form of the polynomial will be y = (x + 3)(x + 2 )(x - 1 )(x - 3 )

What is the triangle?Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.
For an isosceles triangle, the value of two opposite angles is equal and the opposite sides are also equal.
The Sum of the three angles is equal to 180 degrees so the third angle will be calculated as:-
Angle = 180 - 142 - 19 = 19
Now applying Lami's theorem in the triangle we will get the third side.
[tex]\dfrac{sin\angle A}{a} = \dfrac{sin\angle B}{b} = \dfrac{sin\angle C}{c}[/tex]
[tex]\dfrac{Sin 19}{42}= \dfrac{Sin142}{x}[/tex]
[tex]x = \dfrac{42\times Sin 142}{Sin19}[/tex]
x = 79
Therefore the value of x will be equal to x = 79.

Step-by-step explanation:
The percentage of automobile consumers who are under 50 years of age decreased approximately linearly from 58.8% in 1980 to 50.5% in 1995. (a) Predict when the percentage will be 47% (b) Predict the percentage in 2005
Using a linear function, we have that:
The percentage will be 47% during the year 2001.
The predicted percentage in 2005 is of 44.97%.
Given that, the percentage of automobile consumers who are under 50 years of age decreased approximately linearly from 58.8% in 1980 to 50.5% in 1995.
What is a linear function?Linear functions are those whose graph is a straight line. The standard form of the linear function is f(x)=y= mx + b. A linear function has one independent variable and one dependent variable.
Where, m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
b is the y-intercept, which is the value of y when x = 0 and can also be interpreted as the initial value of the function.
The percentage in 1980 is considered as the initial amount, so b = 58.8. In 15 years, the percentage decreased from 58.8% to 50.5%, hence the slope is given by: m = (50.5 - 58.8)/15 = 0.5533.
Thus, the percentage in t years after 1980 is P(t) = 58.8 - 0.5533t.
Now, t + 1980, for which P(t) = 47.
So, P(t) = 58.8 - 0.5533t
47 = 58.8 - 0.5533t.
0.5533t = 11.8.
t = 11.8/0.5533
t = 21.3.
1980 + 21 = 2001, so the percentage will be 47% during the year 2001.
Now, 2005 is 25 years after 1980, so the percentage is P(25), given as follows: P(25) = 58.8 - 0.5533x25 = 44.97%.

Which of the following is the center and radius of the circle?

Center (2, –7); r = 7
Center (–4, 14); r equals square root 46
Center (4, –14); r = 46
Center (–2, 7); r equals square root 7
The centre of the circle is (-2,7) and the radius is √7 , Option D is the right answer.
What is the standard equation of a Circle ?The standard equation of a Circle is
(x-h)² +(y-k)² = r²
where h and k is the centre of the circle , r is the radius
The given equation is
x² + y² + 4x – 14y + 46 = 0
x² +4x +4 -4 +y² -2.7y + 49-49+46 = 0
(x + 2)² + (y-7)² -4-49+46 = 0
(x + 2)² + (y-7)²= 7
Therefore the centre of the circle is (-2,7) and the radius is √7 ,
Therefore Option D is the right answer.

Answer:
d.
Step-by-step explanation:
Left line is defined when x < 1 (x is less than 1). The point is not full and that means that x = 1 is not included.
Right line is defined when x is greater or equal to one x ≥ 1.
Options that have x < 1 and x ≥ 1 are b and d, so the answer is one of those.
Equations of the lines are in slope-intercept form y = mx + b, where m is slope and b is y-intercept.
Right line has steeper slope than left line, so the slope of right line will have bigger absolute value. That is the case with option d. (Left line has slope -1 and right one has slope -2, absolute value of right slope is bigger.)
You could also check with y-intercepts. Left line has y-intercept at y = 2 and left line is defined when x < 1. Only option d meets these conditions.
The percentage of automobile consumers who are under 50 years of age decreased approximately linearly from 58.8% in 1980 to 50.5% in 1995.
(A) Predict when the percentage will be 47%.
(B) Predict the percentage in 2005.
Using a linear function, we have that:
a) The percentage will be 47% during the year of 2001.
b) The predicted percentage in 2005 is of 44.97%.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.The percentage in 1980 is considered as the initial amount, hence b = 58.8. In 15 years, the percentage decreased from 58.8% to 50.5%, hence the slope is given by:
m = (50.5 - 58.8)/15 = 0.5533.
Hence the percentage in t years after 1980 is given by:
P(t) = 58.8 - 0.5533t.
Item a:
This is t + 1980, for which P(t) = 47, hence:
P(t) = 58.8 - 0.5533t
47 = 58.8 - 0.5533t.
0.5533t = 11.8.
t = 11.8/0.5533
t = 21.3.
1980 + 21 = 2001, hence the percentage will be 47% during the year of 2001.
Item b:
2005 is 25 years after 1980, hence the percentage is P(25), given as follows:
P(25) = 58.8 - 0.5533x25 = 44.97%.
