What is the product?
(x − 3)(2x2 − 5x + 1)
2x3 − x2 + 16x + 3
2x3 − 11x2 + 16x + 3
2x3 − 11x2 + 16x − 3
2x3 − x2 + 16x − 3
Step-by-step explanation:
= (x - 3)(2x² - 5x + 1)
= 2x³ - 5x² + x - 6x² + 15x - 3
= 2x³ + (-5 - 6)x² + (1 + 15)x - 3
= 2x³ - 11x² + 16x - 3
Option → C
The product of the given polynomials is: C. 2x³ - 11x² + 16x - 3.
What is the Product of Two Polynomials?The product of two polynomials is simply the multiplication of both polynomials together.
Given:
(x − 3)(2x² − 5x + 1)
Multiply using the distributive property
x(2x² − 5x + 1) -3(2x² − 5x + 1)
2x³ - 5x² + x - 6x² + 15x - 3
Combine like terms
2x³ - 11x² + 16x - 3

GIVEN THAT TAN Ꝋ= - 4/3 AND Ꝋ IS IN QUADRANT II, FIND SIN 2Ꝋ
Answer:
sin 2θ = -24/25
Step-by-step explanation:
see the below formula of sin x in terms of tan x
by substituting => -4/3 / ± √(16/9 + 1)
=> -4/3 / ± √(25/9)
=> -4/3 / ± 5/3
=> ± -4/5
=> ± 4/5
as theta is in second quadrant is in 2nd quadrant sin value is positive
so sin θ = 4/5 and cos θ = -3/5
now sin 2θ = 2 sinθcosθ
= 2 * 4/5 * -3/5
= -24/25

Ken wants to install a row of ceramic tiles on a wall that is 21 3/8 inches wide. Each tile is 4 1/2 inches wide. What fraction of a tile must he install at the end of the row to totally fill the space?
Answer: 1/4
Step-by-step explanation:
He needs 4 3/4 whole tiles, you could round it to 5 whole tiles. He needed 4 3/4 whole tiles. To completely fill in all the spaces on the wall evenly, it needs to be 5 even, while, tiles. To fill in the empty space, you must subtract 5 and 4 3/4, which explains why Part A says “How many whole tiles does he need” and the answer “4 3/4” So, Subtraction: 5- 4 3/4 = 1/4!
Your welcome :)
Ken must install 3/4 fraction of tile at the end of the row to totally fill the space.
Given that,
Ken wants to install a row of ceramic tiles on a wall that is 21 3/8 inches wide. Each tile is 4 1/2 inches wide. What fraction of a tile must he install at the end of the row to totally fill the space is to be determined.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
Total length of the wall = 21 3 / 8 = 21 . 375
Width of tile = 4 1/2 = 4.5
Now, the ratio of wall to tile = 21. 375 / 4.5
quotient = 18 Remainder = 3.375
Now the ratio of the remainder to the tile = 3.375 / 4.5 = 0.75 or 3 / 4.
Thus, Ken must install 3/4 fraction of tile at the end of the row to totally fill the space.

Answer:
y=[tex]\frac{3}{4}[/tex]x-2
Step-by-step explanation:
Since it will be parallel that means m=[tex]\frac{3}{4}[/tex]
then you can use point slope form (y-y1)=m(x-x1): y+5=[tex]\frac{3}{4}[/tex](x+4)
then you can distribute the [tex]\frac{3}{4}[/tex]: y+5=[tex]\frac{3}{4}[/tex]x+3
then subtract 5: y=[tex]\frac{3}{4}[/tex]x-2

Use point-slope form to write the equation of a line that passes through the point
(-7, 10) with slope -5.
Answer:
y = -5x - 25
Step-by-step explanation:
Substitute into form of y - y1 = m(x - x1): (Take the point (-7,10) for x1 & y1, m would be the slope)
y - 10 = -5(x -(-7))
y - 10 = -5(x + 7)
y - 10 = -5x - 35
y = -5x - 25
Answer:
y= -5x-25
Step-by-step explanation:
Equation of line with points given =
y = mx + b
m = -5 , x = -7 , y = 10 while the intercept, b is not given, so we need to find that...
Therefore, we substitute the value for the given equation
10 = -5*-7 + b
10 = 35 + b
b = 10 - 35
b = -25
Therefore we substitute the value for m and b to the equation of line
y = -5x - 25
What is the value of K?
Answer:
The one guy is right k equals 43.6
Hope This Helps!!!
The value of k using Vertical angles is 43.6 degree.
Vertical angles are a pair of non-adjacent angles that are formed by the intersection of two lines. When two lines intersect, they create four angles at the intersection point.
Vertical angles are the angles that are opposite to each other and share the same vertex but are not adjacent. They are Congruent.
As, k and 43.6 are Vertical angles.
So, k = 43.6

A car passes through a tollbooth at 8:00 A.M. and begins traveling east at an average speed of the same tollbooth an hour later and begins traveling east at an average speed of 60 miles per hour. a. Write an equation for each car that relates the number of hours x since 8:00 A.M. to the distance in miles y the car has traveled. Explain what the slope of each equation represents. b. Graph the system of equations on the coordinate plane. c. If neither car stops, at what time will the second car catch up to the first car? Explain how you determine your answer.
The distance traveled by both cars is an illustration of a linear function.
The equations of both cars are [tex]\mathbf{y=60x - 540}[/tex] and [tex]\mathbf{y=45x - 360}[/tex]Both cars meet at 12:00pmCar A
Speed = 45 miles per hour
So, the coordinates of car A are:
[tex]\mathbf{(x,y) = (8,0) (9, 45) (10, 90) ....}[/tex]
Car B
Speed = 60 miles per hour
So, the coordinates of car B are:
[tex]\mathbf{(x,y) = (9, 0) (10, 60) (11, 120) ....}[/tex]
(a) The equation of both cars
Car A
This is calculated as:
[tex]\mathbf{y = mx+ b}[/tex]
Where m represents slope/speed.
So, m = 45
This gives
[tex]\mathbf{y = 45x + b}[/tex]
y = 0, when x = 8.
So, we have:
[tex]\mathbf{0= 45\times 8 + b}[/tex]
[tex]\mathbf{0= 360 + b}[/tex]
Solve for b
[tex]\mathbf{b=- 360}[/tex]
So, the equation of car A is:
[tex]\mathbf{y=45x - 360}[/tex]
Car B
This is calculated as:
[tex]\mathbf{y = mx+ b}[/tex]
Where m represents slope/speed.
So, m = 60
This gives
[tex]\mathbf{y = 60x + b}[/tex]
y = 0, when x = 9.
So, we have:
[tex]\mathbf{0= 60\times 9 + b}[/tex]
[tex]\mathbf{0= 540 + b}[/tex]
Solve for b
[tex]\mathbf{b=- 540}[/tex]
So, the equation of car B is:
[tex]\mathbf{y=60x - 540}[/tex]
(b) The graphs
See attachment
(c) The time which both cars meet
We have:
[tex]\mathbf{y=60x - 540}[/tex] and [tex]\mathbf{y=45x - 360}[/tex]
Equate both
[tex]\mathbf{60x - 540=45x - 360}[/tex]
Collect like terms
[tex]\mathbf{60x - 45x = 540- 360}[/tex]
[tex]\mathbf{15x = 180}[/tex]
Divide both sides by 15
[tex]\mathbf{x = 12}[/tex]
This means that both cars meet at 12:00pm
