Answer:
x - 2 and x - 1 can be possible length and width of the rectangle.
Step-by-step explanation:
Area = x² - 3x + 2
◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇
To find possible length and width we can factorize the above expression.
◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇
x² - 3x + 2 ( 2 = -1 × -2 )
x² - x - 2x + 2 ( 3 = -1 + -2 )
x(x - 1) + -2(x - 1)
(x - 2) (x - 1)
◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇
x - 2 and x - 1 can be possible length and width of the rectangle.

Which one is true? Select all that apply.
A. The slope of AC is equal to the slope of BC.
B. The slope of AC is equal to the slope of BD.
C. The slope of AC is equal to the slope of line t.
D. The slope of line t is equal to EC/AE
E. the slope of line t is equal to FB/FD
F. The slope of line t is equal to AE/FD
Answer:
Options (A), (B), (C) and (E).
Step-by-step explanation:
Option (A).
Slope of AC is equal to the slope of BC.
Since, points A, B and C are collinear points,
Slopes of AC and BC will be equal.
True.
Option (B).
Since, points A, B, C and D are collinear points, slope of AC and BD will be equal.
True.
Option (C).
Points A and C are lying on line 't'.
Therefore, slope of line 't' and line AC will be equal.
True.
Option (D).
Slope of 't' = slope of line AC
= [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{AE}{EC}[/tex]
False.
Option (E).
Slope of line 't' = slope of line BD
= [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{FB}{FD}[/tex]
True.
Option (F).
Slope of line 't' = [tex]\frac{AE}{FD}[/tex]
False.

Given f (x) = 2x² +1evaluate f (-1).
Answer:
3
Step-by-step explanation:
f(x) = 2x^2 + 1
f(-1) means that wherever you see an x on the right hand side, you substitute -1.
f(-1) = 2(-1)^2 + 1 = 2 + 1 = 3

Simplify each equation using PEMDAS:
Parentheses (x)
Exponents x²
Multiplication and Division, left to right × ÷
Addition and Subtraction, left to right - +
It is also important to follow PEMDAS when working within grouping symbols like parentheses.
Also, remember that two negatives make a positive, and when a negative and positive are multiplied, the result is always negative.

Find the maximum height of the rocket and explain in at least threes sentence how you calculated your answer of y = - 16x ^ 2 + 480x
Answer:
The maximum height of the rocket is 3600
Step-by-step explanation:
The vertex of the quadratic equation y = ax² + bx + c is (h, k), where
h = [tex]\frac{-b}{2a}[/tex]k = y at x = hThe vertex (h, k) is a minimum point if a is positive The vertex (h, k) is a maximum point if a is negativeThe height of the rocket calculated using the equation y = -16x² + 480x, where y is the height and x is the time
To find the maximum height, do that
Find the x-coordinate of the vertex of the equation ⇒ hSubstitute the value of x in the equation by h to find the y-coordinate of the equation ⇒ kThe maximum height equal the value of kLet us do that
∵ y = -16x² + 480x
∴ a = -16 ⇒ the vertex is a maximum point
∴ b = 480
→ Use the rule above to find h
∵ h = [tex]\frac{-b}{2a}[/tex]
∴ h = [tex]\frac{-480}{2(-16)}[/tex] = [tex]\frac{-480}{-32}[/tex]
∴ h = 15
∵ k = y at x = h
→ Substitute x by 15 in the equatuion and y by k to find x
∵ k = -16(15)² + 480(15)
∴ k = -3600 + 7200
∴ k = 3600
∵ The maximum height equal the value of k
∴ The maximum height of the rocket is 3600
Y'all please help me! Basically just match up the points with an equation.
write an equation of the line that passes through the given points.
1. (-3, 2) (5, -2) 2.(-2, -4) (0,-8) 3.(8, -10) (0,2) 4.(-5, 4) (-3, -4) 5.(5, 0) (-2, 4)
y=-4x-16 y=-3/2x+2 y=-2x-8 y=-1/2x+1/2 y=-4/7x+2 6/7
What is the answer to this equation? 2x+2x+2=4x+2
Answer:
0
Step-by-step explanation:
You start off with 2x + 2x + 2 = 4x + 2.
You would then add like terms, as shown below.
4x + 2 = 4x + 2
Now, you would subtract 4x from both sides, and that would leave you with:
2 = 2
You would now subtract 2 from both sides, which would now leave you with 0.

What is the answer to this fast smart people
Answer:
m<R = 106°
Step-by-step explanation:
Given,
m<R = (6x+10)°
m<S = (2x+5)°
m<T = (3x-11)°
Now,
6x+10°+2x+5°+3x-11° = 180°{the sum of angles of triangle is 180°}
or, 11x+4° = 180°
or, 11x = 180°-4
or, x = 176°/11
or, x = 16°
therefore, x = 16°
m<R = (6x+10)°
= 6×16°+10°
= 96°+10°
= 106°
Guys pls help me im failing my grade and i really need help plsssss and dont do it for the points
Answer:
simplified: [tex]\frac{3}{5}[/tex]
unsimplified: [tex]\frac{12}{20}[/tex]
Step-by-step explanation:
Since the fractions have the same denominator, all we have to do is subtract the numbers in the numerator:
15 - 3 = 12
The difference of the two fractions is [tex]\frac{12}{20}[/tex]. To simplify this answer, divide both the numerator and the denominator by 4:
12/4 = 3
20/4 = 5
The difference in simplified form is [tex]\frac{3}{5}[/tex].

The height, h in feet, of a rocket is given by h=-16t^2+64t+190, where t is time in seconds. Find the maximum height of the rocket and find the time the rocket was in the air.
Step-by-step explanation:
The height, h in feet, of a rocket is given by, where t is time in seconds.
[tex]h=-16t^2+64t+190[/tex] ...(1)
We need to find the maximum height of the rocket and find the time the rocket was in the air. For maximum height, put [tex]\dfrac{dh}{dt}=0[/tex]
[tex]\dfrac{d(-16t^2+64t+190)}{dt}=0\\\\-32t+64=0\\\\t=\dfrac{64}{32}\\\\t=2\ s[/tex]
So, it will reach its maximum height in 2 seconds.
Now put t = 2 in equation (1) as follows :
[tex]h(2)=-16(2)^2+64(2)+190\\\\=254\ \text{feet}[/tex]
So, the maximum height of the rocket and find the time the rocket was in the air is 254 feet and 2 seconds respectively.
De acuerdo con una encuesta se determino que en una region hay igual numero de personas lic en administracion comercio servicio de salud y servicio municipal ademas se encontro que 35% de los administrativos 25% de los comerciantes 20% de los servidores de salud y 15% de servicio municipal son mujeres cual es la probabilidad de que una mujer escogida al azar del grupo sea administradora
Answer:
La probabilidad de que una mujer sea administradora es de 0,35
Step-by-step explanation:
Sean A B, C y D los eventos de las mujeres administrativas, comerciantes, trabajadoras de salud y proveedoras de servicios municipales.
Sus probabilidades están dadas por
P (a) = 35% = 0,35
P (b) = 25% = 0,25
P (c) = 20% = 0,2
P (d) = 15% = 0,15
Como los eventos son independientes, la probabilidad conjunta sería
P (B∩C∩D) = P (D) * P (B) * P (C) = 0.25 * 0.2 * 0.15 = 0.0075
P (A / B∩C∩D) = P (A∩B∩C∩D) / P (B∩C∩D)
= 0,35 * 0,0075 / 0,0075 = 0,35
Por lo tanto, la probabilidad condicional de obtener la mujer administradora es la misma que la probabilidad individual de obtener la administradora, ya que los eventos son independientes.
La probabilidad de que una mujer sea administradora es de 0,35
English
Let A B, C and D be the events of the women administrative, merchants, health workers and municipal services providers.
Their probabilities are given by
P (a) = 35% = 0.35
P (b)= 25% = 0.25
P (c) =20% = 0.2
P (d) = 15 % = 0.15
As the events are independent then the joint probability would be
P (B∩C∩D)= P(D) * P(B)* P (C) = 0.25* 0.2*0.15= 0.0075
P(A/B∩C∩D) = P(A∩B∩C∩D)/P(B∩C∩D)
= 0.35*0.0075/ 0.0075= 0.35
Therefore the conditional probability of getting the administrator woman is the same as the individual probability of getting the woman administrator as the events are independent.
Probability of woman administrator is 0.35

how to change percentage to degree
Answer:
A full circle has 360 degrees, which means that 100% of the circle is 360 degrees. First convert the percentage into a decimal. If you multiply 360 by 0.90, you get the degree measure that corresponds to the percentage, which is 324.
