Answer:
The answer is 4(3x² + 1)(x - 5).
Step-by-step explanation:
First, you have to take out all the common ratios :
12x³ - 60x² + 4x - 20
= 4(3x³ - 15x² + x - 5)
Next, you have to factorize the inner brackets :
3x³ - 15x² + x - 5
= 3x²(x - 5) + (x - 5)
= (3x² + 1)(x - 5)
Answer:
4(3x² + 1)(x - 5)
Step-by-step explanation:
Given
12x³ - 60x² + 4x - 20 ← factor out 4 from each term
= 4(3x³ - 15x² + x - 5)
Factor the first/second and third/fourth terms inside the parenthesis
= 4[ 3x²(x - 5) + 1(x - 5) ] ← factor out (x - 5) from each term
= 4(3x² + 1)(x - 5)

The parametric equation that represents this situation is __
A. x = (34cos(30°)t and y = –16t2 + (34sin(30°))t
B. x = (34cos(30°)t and y = –16t2 + (34sin(30°))t + 3
C. x = (34cos(30°)t + 3 and y = –16t2 + (34sin(30°))t + 3

The bean bag’s path is part of a curve that is a parabola and to the nearest second, the bean bag was in the air for 1 second(s).
What is projectile motion?Projectile motion is the motion of the body, when it is thrown in the air taking the action of gravity on it.
The parametric equation for x and y can be given as,
[tex]x =x_o+ v_o\cos(\theta)t \\y =y_o -\dfrac{1}{2}at^2 + (v_o\sin(\theta))t[/tex]
Here, (vo) is the initial speed, (h) is the height and θ is the angle of throw.
The player throws a bean bag from the height of 3 feet with an initial velocity of 34 feet per second at an angle of 30º.
Let suppose the time is t second. Thus, the parametric equation that represents this situation are,
[tex]x = (34\cos(30^o)t \\y = -16t^2 + (34\sin(30^o))t + 3[/tex]
The bean bag’s path is part of a curve. This path is in the form of parabola.
To the nearest second, the bean bag was in the air for 1 second(s).
Thus, the bean bag’s path is part of a curve that is a parabola and to the nearest second, the bean bag was in the air for 1 second(s).

5. Find JK to the nearest whole number.
A
Answer:
JK ≈ 63 units
Step-by-step explanation:
Using the sine ratio in the right triangle
sin44° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{JK}{JL}[/tex] = [tex]\frac{JK}{90}[/tex] ( multiply both sides by 90 )
90 × sin44° = JK , that is
JK ≈ 63 ( to the nearest whole number )
Answer:
Sin(x) = Opposite ÷ Hypotenuse
Sin(44) = JK ÷ 90
0.6946583705 = JK ÷ 90
0.6946583705 × 90 = JK
JK = 62.5192533413
Rounding JK to the nearest whole number:
JK = 63

rs= 4x-9, st= 19, rt=8x-14
The value of x is 6
How to determine the valueFrom the information given, we have that;
Line RS = 4x - 9Line ST = 19Line RT = 8x - 14It is important to note that line RT is a line with segments RS and ST and S and the line between R and T
This can be expressed as;
RS + ST = RT
substitute the values into the equation, we have;
4x - 9 + 19 = 8x - 14
collect like terms
4x - 8x = -14 + 9 - 19
subtract like terms
-4x = -24
make 'x' the subject of formula
-4x/-4 = -24/-4
x = 6
Thus, the value of x is 6

Consider a total of 1,000 people. If it was said that within 1 deviation (of the mean) of all people like MATH 123, how many of the group should like MATH 123?
Answer:
680 students
Step-by-step explanation:
The 68 - 95 - 99.7 rule (empirical rule) states that 68% of the population lies within one standard deviation of the mean, 95% of the population lies within two standard deviations and 95% of the population lies within three standard deviations.
Hence since it was said that within 1 deviation (of the mean) of all people like MATH 123, therefore the number of people that like MATH 123 is:
number of people that like MATH 123 = 68% of the population
number of people that like MATH 123 = 0.68 * 1000
number of people that like MATH 123 = 680 students

Identify the property illustrated. (Commutative, Associative, Identity, Property of Zero, Property of -1)
1. -1 • (-6) =6
2. 0 • (-76.3) =0
3. (3x) y = 3 (xy)
4. 0.3 • (-3) = -3 • 0.3
-1 × (-6) = 6 ( because of multiplicative property of -1)
0 ×(-76.3) = 0 (zero property of multiplication)
(3x)y = 3(xy) (commuative property)
0.3 × (-3) = -3 × 0.3 ( commutative property)
As we know that,
The commutative property is a math rule that says that the order in which we multiply numbers does not change the product.
The associative property is a math rule that says that the way in which factors are grouped in a multiplication problem does not change the product.
Identity property states that a number, known as the identity, can be added to, subtracted from, multiplied by, or divided into a number without changing the number.
Zero property of multiplication is defined as “when we multiply any number by zero, the resulting product is always a zero”.
Multiplicative property of -1 atates that any number multiplied by -1 gives the same but with its opposite sign.
From the given example we can say that
-1 × (-6) = 6 ( because of multiplicative property of -1)
0 ×(-76.3) = 0 (zero property of multiplication)
(3x)y = 3(xy) (commuative property)
0.3 × (-3) = -3 × 0.3 ( commutative property)

A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 55 pounds each, and the small boxes weigh 25 pounds each. There are 125 boxes in all. If the truck is carrying a total of 4775 pounds in boxes, how many of each type of box is it carrying?
There are 70 small boxes and 55 big boxes.
How to calculate the equation?Let x = small box
Let y = large box
The equation will be:
x + y = 125 ....i
25x + 55y = 4775 ..... ii
From equation i, y = 125 - x.
25x + 55y = 4775
25x + 55(125 - x) = 4775
25x + 6875 - 55x = 4775
Collect like terms
25x - 55x = 4775 - 6875
30x = 2100
x = 2100/30
x = 70
Since x + y = 125
y = 125 - 70 = 55
Therefore, there are 70 small boxes and 55 big boxes.

Expand $(2t - 7)^2.$
Answer:
4t^2 - 28t + 49
Step-by-step explanation:
(2t - 7)^2
Use FOIL.
(2t - 7)^2 =
= (2t - 7)(2t - 7)
= 4t^2 - 14t - 14t + 49
Combine like terms.
= 4t^2 - 28t + 49
(2t - 7)² on expansion results in 4t² - 28t + 49.
What are Algebraic Identities?The algebraic equations which can be used for all variables in the equation is called Algebraic identities. These identities used in factorization of polynomial expressions as well as in the computation of algebraic expressions.
Some of the standard algebraic identities are:
(a + b)² = a² + 2ab + b²
(a - b)² = a² - 2ab + b²
a² - b² = (a + b) (a - b)
Here we have the expression (2t - 7)².
Using the second identity (a - b)² = a² - 2ab + b², we can write,
(2t - 7)² = (2t)² - (2 × 2t × 7) + 7²
= 4t² - 28t + 49
Hence the expression (2t - 7)² is expanded to 4t² - 28t + 49 using the algebraic identity (a - b)² = a² - 2ab + b².

A process produces a certain part with a mean diameter of 3 inches and a standard deviation of 0.05 inches. The lower and upper engineering specification limits are 1.80 inches and 3.05 inches. What is the Cp (measure of potential capability)
Answer:
The correct answer is 4.167
Step-by-step explanation:
According to the given scenario, the calculation of the Cp i.e. measure of potential capability is as follows;
= (USL - LSL) ÷ 6 × standard deviation
= (3.05 inches - 1.80 inches) ÷ 6 × 0.05
= 1.25 ÷ 0.3
= 4.167
hence, the calculation of the Cp i.e. measure of potential capability is 4.167

Step-by-step explanation:

We want to perform a sum of vectors and draw the resultant vector. The resultant vector will be <4, 0> and its graph can be seen at the end.
If we see the image, we can write the vectors as:
w = <3, 3>u = <-3, -4>v = <-4, -1>Now we want to sum:
u - v + w
Remember that in the sum of the vectors we just add (subtract) the correspondent components, then we will have:
u - v + w = <-3, -4> - <-4, -1> + <3, 3> = <-3 + 4 + 3, -4 + 1 + 3> = <4, 0>

For what values of x and y must ABCD be a parallelogram?
Suppose lines EF and GH are reflected over the line y = x to form the lines JK and LM. Which statement would be true about the lines?
A.
Line JK and line LM will be parallel.
B.
Line JK and line LM will be perpendicular.
C.
The slope of line JK will be the same as the slope of line EF.
D.
The slope of line LM will be the negative reciprocal of the slope of line GH.
Answer:
A.
Step-by-step explanation:
I believe the answer is A. (Line JK and line LM will be parallel) because lines EF and GH are parallel. Therefore if the are just reflected, the new set of lines will also be parallel.
EF: (-9,1) (-4,9)
[tex]\frac{1-9}{-9+4}[/tex] = [tex]\frac{-8}{-5}[/tex] = [tex]\frac{8}{5}[/tex] or 1.6
GH: (-5,-2) (0,6)
[tex]\frac{-2 - 6}{-5-0}[/tex] = [tex]\frac{-8}{-5}[/tex] = [tex]\frac{8}{5}[/tex] or 1.6
Same slope and different y-intercept means the lines a parallel
