The coefficients in the expansion of (x + y)4
are
O A. 1, 4, 6, 4, 1
OB. 0, 1, 4, 6, 4, 1, 0
C. 0, 4, 6, 4,0
D. 1, 4, 6, 6, 4, 1
Answer:
A
Step-by-step explanation:
Notice: The literal factors are all the combinations of a and b where the sum of the exponents is 4: a4, a3b, a2b2, ab3, b4.
The degree of each term is 4.
The first term is actually a4b0, which is a4 · 1.
Thus to "expand" (a + b)5, we would anticipate the following terms, in which the sum of all the exponents is 5:
(a + b)5 = ? a5 + ? a4b + ? a3b2 + ? a2b3 + ? ab4 + ? b5
The question is, What are the coefficients?
They are called the binomial coefficients. In the expansion of
(a + b)4, the binomial coefficients are
1 4 6 4 1
The coefficients in the expansion are 1, 4, 6, 4, 1.
What is Binomial Expansion?The sum of exponents of x and y is always n. The binomial coefficients which are equidistant from the beginning and from the ending are equal i.e. [tex]^nC_0[/tex]= [tex]^nC_n[/tex], [tex]^nC_1[/tex]= [tex]^nC_{n-1}[/tex], [tex]^nC_2[/tex]= [tex]^nC_{n-2}[/tex] ,….. etc.
The expansion of [tex](x+ y)^4[/tex]
= [tex]x^4[/tex] + 4x³y + 6x²y² + 4xy³ + [tex]y^4[/tex]
So, the highest degree is 4.
and, The literal factors are all the combinations are [tex]x^4[/tex], 4x³y, 6x²y², 4xy³,[tex]y^4[/tex]
Hence, the coefficients in the expansion are 1, 4, 6, 4, 1.

Given a polynomial f(x), if (x - 2) is a factor, what else must be true?
f(0) = -2
f(-2) = 0
f(2) = 0
f(0) = 2
show work pls
Answer:
f(2)=0. The third option is correct.
Step-by-step explanation:
Suppose we have a polynomial called f(x) and we know (x-2) is a factor of f. This means that we can express f(x) as:
f(x)=(x-2)\cdot g(x)
Being g(x) another unknown function.
Option 1: f(0)=(0-2)\cdot g(0)=-2\cdot g(0). Since we don't know the value of g(0), we cannot assure f(0)=-2. Incorrect
Option 2: f(-2)=(-2-2)\cdot g(-2)=-4\cdot g(-2). Since we don't know the value of g(-2), we cannot assure f(-2)=0. Incorrect
Option 3: f(2)=(2-2)\cdot g(2)=0\cdot g(0)=0. Regardless of the value of g(0), f(0) must be 0. Correct
Option 4: f(0)=(0-2)\cdot g(0)=-2\cdot g(0). Since we don't know the value of g(0), we cannot assure f(0)=2. Incorrect

Dan orders supplies for the science lab. Each of the 30 stations in the chemistry lab needs 5 feet of rubber tubing. If rubber tubing sells for $8.25 per yard, how much will it cost to equip all stations?
It will cost $412.50 for equipment for all stations.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Dan orders supplies for the science lab. Each of the 30 stations in the chemistry lab needs 5 feet of rubber tubing. If rubber tubing sells for $8.25 per yard.
The cost will be calculated as below,
3 feet = 1 yard
5 x 30 = 150 feet
8.25 per yard = cost
150/ 3 = 50 yards (total tubing needed)
50 x 8.25 = $ 412.50

Answer:
2,3
Step-by-step explanation:
The slope of the line that passes through points (1, 1) and (7, 5) is 2/3.
What is slope ?Slope is a notation that shows that a surface of which one end or side is at a higher level than another surface.
The formula for slope of a line that passes through two points (x₁.y₁) and (x₂,y₂) is,
y₂ - y₁ = m(x₂ - x₁)
The given points are, (1, 1) and (7, 5).
The slope of the line is given by formula m = (y₂-y1)/(x₂-x₁)
m= (5-1)/(7-1)
m = 4/6
m = 2/3

Use the given x and y values to write a direct variation equation
x=5, y=30
Answer:
The direct variation equation is y = 6x
Step-by-step explanation:
The direct variation equation is y = kx, where
k is the constant of variationTo find the value of k, use the initial values of x and y
∵ y = 5, y = 30
∵ y = k x
→ Substitute the values of x and y to find k
∵ x = 5 and y = 30
∴ 30 = k (5)
∴ 30 = 5k
→ Divide both sides by 5
∴ [tex]\frac{30}{5}=\frac{5k}{5}[/tex]
∴ 6 = k
→ Substitute it in the form of the equation
∴ y = 6x
The direct variation equation is y = 6x

Step-by-step explanation:
radius = 1/2 diameter

This one is easy. Because the radius of a circle (or a semicircle) is half of the diameter, you can simply divide the diameter by 2.
Each of the 25 students in Mr. McDonald class sold 16 raffle tickets if each ticket cost $15 how much money did Mr. McDonald’s students raise PLEASE HELP
Answer:
Mr. McDonald's class raised $6,000 dollars.
Step-by-step explanation:
So they're are 25 students in the class and they each sold 16 raffle tickets. The easiest way to do this problem is to first find the amount of raffle tickets sold and then multiply that by 15. You could also just do 25*16*15 but that doesn't make much sense just thinking about it. So the first operation we have to do is 25*16 because multiplication is repeated addition so we're basically doing 16+16 25 times to see how much raffle tickets were sold. So that is 400 and then we multiply by 15 because each ticket sold for 15 dollars so if we sold 400 raffle tickets for 15 dollars each, again multiplication is repeated addition so we do 15+15 400 times which is 400*15=6,000. So Mr.McDonald's class raised $6,000 dollars.

A bag contains 12 red marbles the ratio of red marbles to blue marbles is 3:4 find the number of blue marbles in the bag
Answer:
16
Step-by-step explanation:
If the ratio is 3 red marbles to 4 blue marbles we can solve this using the following:
[tex]\frac{12}{b} = \frac{3}{4}[/tex]
[tex]12 * 4 = 3b\\48 = 3b\\\frac{48}{3} = b\\b = 16[/tex]
So we have 16 blue marbles.
Based on the ratio of red to blue marbles, the number of blue marbles in the bag is 16 marbles.
The bag has red marbles to blue marbles in a ratio of 3:4.
If there are 12 red marbles, the number of blue marbles can be found by direct proportion:
3 : 4
12 : x
Cross-multiply:
3x = 48
x = 48/3
x = 16 blue marbles
In conclusion, there are 16 blue marbles in the bag.
