Use the function f(x) = 2x^2 − 3x − 5 to answer the questions.
Part A: Completely factor f(x). (2 points)
Part B: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)
Part C: Describe the end behavior of the graph of f(x). Explain. (2 points)
Part D: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part B and Part C to draw the graph. (4 points)
Answer:
Step-by-step explanation:
A
(2x - 5)(x + 1)
B)
The x intrcepts occur when the factors equal zero.
2x - 5 = 0
2x = 5
x = 5/2
x = 2 1/2
C
I will give the the minimum from completing the square
y = 2(x - 0.75)^2 - 6.125
as x approaches + infinity, y approaches + infinity.
as x approaches - infinity, y approaches + infinity.
It's a quadratic. The y values go to plus infinity, when x goes from - infinity to + infinity.
D
Desmos is the most useful tool for this part of the question. What it shows is the two roots and the minimum at (0.75,-6.125. A parabola does what the end behavior describes. The roots are clearly labeled as is the minimum.
If you simplify(x^3/x/x)^3, what power rules do you need to simplify it? a. Addition Rule and Power of a Power Rule b. Subtraction rule and Power of a Power. c. Division Rule and Power of a Power Rule d. Power of a Product Rule and Power of a Power Rule e. None of these choices
Answer:
. c. Division Rule and Power of a Power Rule
Step-by-step explanation:
(x^3/x/x)^3
=(x³/x/x)³
First we need to solve the brackets. Anything written in the fraction form a/b/c can be written as a*c/b.
Similarly (x³/x/x)³ can be written as (x*x³/x)³
Solving further the x can be cancelled by x leaving x³ behind.
(x³)³
Now applying the Power of a Power Rule
x³*³= x⁹
First the division rule and then the power rule is applied.
Jim has a toolbox with a volume of 9,072 cubic inches. The height of the toolbox is 14 inches and the width of toolbox is 1 foot.
Answer: [tex]54\ in.[/tex]
Step-by-step explanation:
Given
The volume of the toolbox is [tex]9072\ in.^3[/tex]
The height of the toolbox is [tex]h=14\ in.[/tex]
The width of the toolbox is [tex]w=1\ ft\ or\ 12\ in.[/tex]
Suppose the length of the box is [tex]l[/tex]
The volume of the toolbox is given by [tex]V=l\times w\times h[/tex]
Insert the value to find the length
[tex]\Rightarrow 9072=14\times 12\times l\\\\\Rightarrow l=\dfrac{9072}{168}\\\\\Rightarrow l=54\ in.[/tex]
The length of the box is [tex]54\ in.[/tex]

A student made a table to compare the number of hours she studied to her quiz scores. Do her scores show a proportional relationship? Why or why not?
Hours of study | Quiz Scores
2.0 40
3.5. 70
4.0 80
5.0 100
Answer:
Yes
Step-by-step explanation:
2 hours=40
so 1 hour=20
if we use that:
3.5x20=70 as stated
4x20=80 as stated
5x20=100 as stated
so there is a proportional relationshi.

Es una division el cociente es 14, el divisor 19, calcule el dividiendo si se sabe que el residuo resutó ser el maximo.
Answer:
266
Step-by-step explanation:
En Matemáticas, al realizar la operación de División, la regla es la siguiente:
Dividendo ÷ Divisor = Cociente
En la pregunta anterior, se nos da:
Divisor = 19
Cociente = 14
Dividendo =?
Para encontrar el dividendo,
Dividendo = Divisor × Cociente
Por eso,
Dividendo = 19 × 14
= 266
Por lo tanto, el Dividendo = 266

Answer:
V = 214.32
Step-by-step explanation:
Remark
You have to be a little careful with this question. The temptation is just to take the difference of the heights. That is not correct. The difference has to be multiplied by the base to get the volume.
Formula
V = (h1 - h2)* Base
Givens
h1 = 32.9
h2 = 29.1
Base = 56.4
Solution
V = 56.4 ( 32.9 - 29.2)
V = 56.4 * 3.8
V = 214.32

1. solve equation for y: 3x - 4y = 16
2. what are the x- and y- intercepts of the line: 4x - 3y = -24
3. which ordered pair is on the graph of the equation 6x + 3y = 9
4. what is the slope of the line that passes through the points (4,8) and (1,6)
Answer:
1) y = 3/4x - 4
2) x-intercept: (-6,0) y-intercept: (0,8)
3) (-2,7)
4) slope: 2/3
Step-by-step explanation:
1) subtract 3x from both sides, divide -4 from both sides, simplify right side which gives you y = 3/4x -4
2) to get x-inter: plug in 0 for y and solve for x, the equation should look like 4x = -24, divide both sides by 4 which gives you x = -6
get y-inter: plug in 0 for x and solve for y, the equation should look like -3y=-24, divide both sides by -3 which gives you y = 8
3) plug in the points from the choices and go from there
4) slope formula: m = y2-y1/x2-x1
Rule 1: Multiply by 2, then add 1/3 starting from 1. Rule 2: Add 1/2, then multiply by 4 starting from 0. What is the fourth ordered pair using the two sequences
Answer:
(10 1/3, 42)
Step-by-step explanation:
a1 = 1
a2 = a1×2 + 1/3 = 2 1/3
a3 = a2×2 + 1/3 = (a1×2 + 1/3)×2 + 1/3 = a1×4 + 2/3 + 1/3 =
= 4 + 3/3 = 5
a4 = a3×2 + 1/3 = ... = 10 1/3
b1 = 0
b2 = (b1 + 1/2)×4 = (0 + 1/2)×4 = 1/2 × 4 = 2
b3 = (b2 + 1/2)×4 = ((b1 + 1/2)×4 +1/2)×4 = 16×b1 + 16/2 + 4/2=
= 16/2 + 4/2 = 8 + 2 = 10
or (to check we made no mistake)
= (2 + 1/2)×4 = 8 + 2 = 10. => all ok, no mistake
b4 = (b3 + 1/2)×4 = ... = (10 + 1/2)×4 = 40 + 2 = 42
so, the fourth ordered pair (= the fourth elements of each sequence) is therefore (10 1/3, 42)
Point E is located at -12 on the number line.Point F is located at point 9 on the number line. What is the distance between Point F on the number line?
Answer:
21 points
Step-by-step explanation:
Point E is located at -12 that is 12 points less than zero. And Point F is located at point 9 which means that is 9 points after zero.
So the total distance will be 12+9= 21 points between the two locations Point E and Point F.
We add the total difference from the point zero to get the total distance between the two points.

Please help 5 questions I need help
Answer:
1. <2, <7
2. 58
3. 78
4. a and b
h5. <2 and <7 ( i think this is the same question as the first one)
Step-by-step explanation:
2. 2x + 7 = 123 (you have to make them equal to each other because they are consecutive interior angles)
2x + 7 = 123, subtract 7
2x = 116, divide 2 for both sides to make x by itself
x = 58
3. 78 because of consecutive interior angles

Answer:
AB = 7 cmStep-by-step explanation:
Use the law of cosines to find the side AB:
[tex]AB = \sqrt{(x + 3)^2+x^2-2x(x+3)cos (60)} =[/tex] [tex]\sqrt{x^2+6x+9+x^2-x^2-3x} = \sqrt{x^2+3x+9}[/tex]Use the Heron's area formula next:
[tex]A = \sqrt{s(s - a)(s-b)(s-c)}[/tex], where s- semi perimeters = 1/2[x + x + 3 + [tex]\sqrt{x^2+3x+9}[/tex]) = 1/2 (2x + 3 + [tex]\sqrt{x^2+3x+9}[/tex])s - a = 1/2 (2x + 3 + [tex]\sqrt{x^2+3x+9}[/tex] - 2x - 6) = 1/2 ([tex]\sqrt{x^2+3x+9 }[/tex] - 3)s - b = 1/2 (2x + 3 + [tex]\sqrt{x^2+3x+9}[/tex] - 2x) = 1/2 ([tex]\sqrt{x^2+3x+9}[/tex] + 3)s - c = 1/2 (2x + 3 + [tex]\sqrt{x^2+3x+9}[/tex] - 2[tex]\sqrt{x^2+3x+9}[/tex]) = 1/2 (2x + 3 - [tex]\sqrt{x^2+3x+9}[/tex])Now
(s - a)(s - b) = 1/4 [(x²+3x+9) - 9] = 1/4 (x² + 3x)s(s - c) = 1/4 [(2x + 3)² - (x² + 3x + 9)] = 1/4 (3x²+ 9x) = 3/4(x² + 3x)Next
A² = 3/16(x² + 3x)(x² + 3x)300 = 3/16(x² + 3x)²1600 = (x² + 3x)²x² + 3x = 40Substitute this into the first equation:
[tex]AB = \sqrt{40 + 9} = 7 cm[/tex]Answer:
AB = 7 cm
Step-by-step explanation:
Sine Rule for Area
[tex]\sf Area =\dfrac{1}{2}ab \sin C[/tex]
where:
a, b and c are the sides opposite angles A, B and Ca and b are the sides and C is the included angleGiven:
Area = √(300) cm²a = (x + 3) cmb = x cmC = 60°Substitute the given values into the formula and solve for x:
[tex]\begin{aligned} \sf Area & = \dfrac{1}{2}ab \sin C \\\\\implies \sqrt{300} & = \dfrac{1}{2}(x+3)x \sin 60^{\circ}\\\\\sqrt{300} & = \dfrac{\sqrt{3}}{4}(x+3)x\\\\\dfrac{4\sqrt{300}}{\sqrt{3}} & = x^2+3x\\\\40 & = x^2+3x\\\\x^2+3x-40 & = 0\\\\ (x-5)(x+8)& = 0\\\\ \implies x & = 5, -8\end{aligned}[/tex]
As length is positive, x = 5 only.
Substitute the found value of x into the expressions for the side lengths:
a = 5 + 3 = 8 cmb = 5 cmCosine rule
[tex]c^2=a^2+b^2-2ab \cos C[/tex]
(where a, b and c are the sides and C is the angle opposite side c)
Substitute the found values into the formula and solve for AB:
[tex]\begin{aligned}c^2 & =a^2+b^2-2ab \cos C\\\implies AB^2 & =8^2+5^2-2(8)(5) \cos 60^{\circ}\\AB^2 & =89-40\\AB^2 & =49\\AB & =\sqrt{49}\\AB & = \pm 7\end{aligned}[/tex]
As length is positive, AB = 7 cm.
