5.4 Find roots (zeroes) of : F(x) = 2x2 + 1
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 2 and the Trailing Constant is 1.
The factor(s) are:
of the Leading Coefficient : 1,2
of the Trailing Constant : 1
Final result :
2x • (2x2 + 1) • (5x - 3)

How do you find the value of x in the triangle?
To find the value of x in a triangle, you need to subtract the sum of the two angles from 180 degrees. Know that the sum of all the angles of a triangle will always equals 180 degrees. Then write down the difference of subtracting the sum of the two angles from 180 degrees and that would equal the value of x.

The value of Tonya's car is $21,000. The car's value depreciates at a rate of 15% per year.
Which function represents the value of the car after t years?
O f(t) = 1.15(21,000)
O f(t) = 21,000(1.15)
O f(t)21,000(0.85)
O f(t) = 0.85(21,000)
Answer:
f(t) = 0.85(21,000)
Step-by-step explanation:
100% - 15% = 85% 0r in decimal form 0.85
0.85 x the original pricen 21,000
Answer:
the answer for this question is: f(t)=21,000(0.85)^t
Step-by-step explanation:
well since its asking what function represents the value, you have to convert the 15 percent into a decimal. so when you put the equation together you can see its 0.85.
hope it helps! :)
How do you find radius from cercumference?
(if at all Possible)
Answer:
r = C/2π
Step-by-step explanation:
You just rearrange the Circumference formula so you can find r.
Circumference formula:
C = 2πr
To find r, you multiply 1/2π on both sides of the equation so you can isolate r:
r = C/2π

that the square root of a rational number can be irrational. Who is correct and why?
Jenna is correct because all square roots are irrational numbers.
Sam is correct because all square roots of rational numbers are rational. An example is 121 - 11.
O Jenna is correct because not all square roots are rational. An example is 2-1.414213
Sam is correct because the properties of square roots state that the square root of a rational number is a rational

Which scatterplot shows a linear association?
Answer:

Step-by-step explanation:
Un huerto escolar tiene una superficie de 4dam2 500m2 y se requiere dividir en seis parcelas rectangulares de igual area ¿ cuantos metros cuadrados tendra cada parcela ?
Answer:
Cada parcela tendrá una extensión de 150 metros cuadrados.
Step-by-step explanation:
De acuerdo con el enunciado el huerto escolar tiene una extensión de 4 decámetros y 500 metros cuadrados.
Tengamos presente que un decámetro es igual a 100 metros cuadrados, entonces el huerto escolar tiene un área total de 900 metros cuadrados. Si dividimos esa área en seis parcelas de igual extensión, tenemos que:
[tex]x = \frac{900\,m^{2}}{6}[/tex]
[tex]x = 150\,m^{2}[/tex]
Cada parcela tendrá una extensión de 150 metros cuadrados.

Answer:
1) A
2) I
3) G
4) B
Step-by-step explanation:
1)
Bottom side: 7c - 1
Tall side: 6c + 2
P = 7c - 1 + 6c + 2 + 3c - 2 + 2c + 4c + 1 + 4c + 2
P = 26c + 2
2)
P = 26c + 2
P = 26(5) + 2
P = 132
3)
P = 2(l + w)
P = 2(3d - 2 + 5d + 1)
P = 16d - 2
4)
P = 16d - 2
P = 16(3) - 2
P = 46

Question 3 V (t) 30(1.05), where t is the time, in years, since opening the account Connie deposits $30 into an account. The value of the account, in dollars, can be modeled as To the nearest cent, what is the average rate of change in the value of the account for the first 3 years? A $0.63/year B $1.58/year С $3.15/year thing D $4.73/year
Answer:
b
Step-by-step explanation:
The average rate of change in the value of the account for the first 3 years is, $3.15/year. So Option C is correct.
What is the rate?Rate is a ratio of change in one quantity w.r.t. change in another quantity. The net change in one quantity is written as, Δy and the net change in another quantity is written as, Δx.
So formula for the rate is,
m = change in one quantity/change in another quantity = Δy/Δx
The average rate of change in the value of the account for the first 3 years can be calculated as follows:
Let t = 0 be the time when the account is opened,
and t = 3 be the end of the third year.
The value of the account at t = 0 is V(0) = 30,
and the value of the account at t = 3 is
V(3) = 30(1.05)³
The average rate of change in the value of the account over the first 3 years is given by the formula:
⇒ (V(3) - V(0)) / (3 - 0)
⇒ (30(1.05)³ - 30) / 3
⇒ $3.15/year
Hence, the average rate of change in the value of the account over the first 3 years is approximately $3.15/year

Given square ABCD, which line segment could be an image of side AD using only a translation?
Answer:
The second one
Step-by-step explanation:
Line segment BC will be an image of side AD using only a translation.
Option 2 is true.
What is Translation?
A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.
Given that;
A figure ABCD is a square.
Now,
Since, ABCD is a square.
So, All sides of square ABCD are equal to each other.
Since, A translation occurs when a figure is moved from one location to another location without changing its size or shape.
Thus, Line segment BC will be an image of side AD using only a translation.
Therefore, Line segment BC will be an image of side AD using only a translation.
