The first three terms of the binomial expansion of (2 – ax)" are 64 – 16bx +100bx?.
Find the value of each of the integers n, a and b.
Ans: n=6, a=5, b=60
Answer:
n = 6, a = 5, b = 60
Step-by-step explanation:
In a binomial function (a + b)ⁿ expression that represents the terms,
(a + b)ⁿ = [tex]\sum_{k=0}^{n}\binom{n}{k}a^{n-k}b^k[/tex]
By this formula,
1st term = [tex]\binom{n}{0}a^{n-0}b^0[/tex] = aⁿ
2nd term = [tex]\binom{n}{1}a^{n-1}b^1[/tex] = [tex]n.a^{n-1}b^1[/tex]
3rd term = [tex]\binom{n}{2}a^{n-2}b^2[/tex] = [tex]\frac{n(n-1)}{2}.a^{n-2}.b^2[/tex]
For the binomial expansion initial 3 terms of (2 - ax)ⁿ = 64 - 16bx + 100bx²
Terms of (2 - ax)ⁿ = [tex]2^n+n(2)^{n-1}(-ax)+\frac{n(n-1)}{2}(2)^{n-2}(-ax)^2[/tex]
= [tex]2^n-n(2)^{n-1}(ax)+n(n-1)(2)^{n-3}(a^2x^2)[/tex]
Comparing the terms of both the expansions,
1st term
2ⁿ = 64
2ⁿ = 2⁶
n = 6
2d term
[tex]n(2)^{n-1}(ax)=16bx[/tex]
[tex]6(2)^{6-1}(a)=16b[/tex]
192a = 16b
b = 12a -----(1)
3rd term
[tex]n(n-1)2^{n-3}(a^2x^2)=100bx^2[/tex]
[tex]6(6-1)2^{(6-3)}(a^2)=100b[/tex]
[tex]30(2)^3(a^2)=100b[/tex]
240a² = 100b
b = 2.4a² -----(2)
From equation (1) and (2),
b = 12a = 2.4a²
a = [tex]\frac{12}{2.4}=5[/tex]
From equation (1)
b = 12a = 60
Therefore, n = 6, a = 5, b = 60

What is the range of the quadratic function graphed below?
Answer:
x
Step-by-step explanation:
he domain of a quadratic function in standard form is always all real numbers, meaning you can substitute any real number for x. The range of a function is the set of all real values of y that you can get by plugging real numbers into x.
Answer:
The range is y [tex]\geq 1[/tex].
Step-by-step explanation:
The graph is shifted up 1 unit, so the range will be everything positive after 1. Anything below 1 would not be in the range.

Two individuals heterozygous for gene Q produced gametes by meiosis, then mated and fertilized one egg. What is the probability that both the egg and sperm will carry the recessive allele?
Answer:
0.25
Step-by-step explanation:
Following the law of segregation which states that only one of the two gene copies noticeable in an organism is diffused to each gamete (egg or sperm cell) and gene allocation is random.
A heterozygous gene for Q = Qq
If these two individuals mate and produce gametes by meiosis,
The probability that both the egg and sperm will carry the recessive allele is determined as follows:
Qq × Qq
Q q
Q QQ Qq
q Qq qq
The probability that both the egg and sperm will carry the recessive allele qq is 25% or 0.25

The zeros of a quadratic function are 1 and 7. To which factored quadratic expression is this function related?
The factored quadratic expression is this function related is to be considered as the (x - 1) and (x-7).
Calculation of the factored quadratic expression:Since The zeros of a quadratic function are 1 and 7.
So,
if we do
(x - 1) = 0
x = 1
And,
(x- 7) = 0
x = 7
Based on this, we can say that The factored quadratic expression is this function related is to be considered as the (x - 1) and (x-7).

The Coney Island Boardwalk is 2.7 miles long. A person jogged at the average speed of 6 mph. How long will it take the person to walk the boardwalk to the end and back?
Answer:0.9
Step-by-step explanation:
The speed of an object is defined as the ratio of distance travelled by it to the time taken. It will take a person 0.9 hours to walk end and back .
What is Speed?Speed is the ratio of distance and time. It is a measure of how fast or slow an object is moving. A high speed object takes less time to travel the same distance as compared to a low speed object.
Given length of island is 2.7 miles.
Speed of the person is 6 mph.
Thus total length for travelling end and back 2.7 + 2.7 =5.4 miles.
Time taken = distance/speed
Therefore, time taken by the person is given as, time is 5.4/6 = 0.9 hours.
Hence, the person will have to take 0.9 hours to walk island end and back.

You are shopping for your holiday feast. The price for
a turkey at Walmart is $12.62 for 10.7 pounds. The
cost for a turkey at Kroger is 8.45 for 8.5 pounds.
Which store has the best unit price for Turkey?
Answer:
Price of 1 pound Turkey at Walmart = $1.18 and Price of 1 pound Turkey at Kroger = $0.99
So, Kroger has the best unit price for Turkey.
Step-by-step explanation:
Price of 10.7 pound Turkey at Walmart = $12.62
Price of 8.5 pound Turkey at Kroger = $8.45
We need to find store that provides best unit price for Turkey.
We need to find price of 1 pound of Turkey for each store
Price of 1 pound of Turkey at Walmart:
Price of 10.7 pound Turkey at Walmart = $12.62
Price of 1 pound Turkey at Walmart = $12.62/10.7
Price of 1 pound Turkey at Walmart = $1.18
Price of 1 pound of Turkey at Kroger
Price of 8.5 pound Turkey at Kroger = $8.45
Price of 1 pound Turkey at Kroger = $8.45/8.5
Price of 1 pound Turkey at Kroger = $0.99
So, Price of 1 pound Turkey at Walmart = $1.18 and Price of 1 pound Turkey at Kroger = $0.99
So, Kroger has the best unit price for Turkey.
A hairstylist schedules 14 hour to trim a customer's hair and 16 hour to style the customer's hair. The hairstylist plans to work 3 13 hours each day for 5 days each week. How many appointments can the hairstylist schedule each week if each customer must be trimmed and styled?
Answer:
40 customers
Step-by-step explanation:
Trimming = 1/4 hours
Styling = 1/6 hours
Working hours per day = 3 1/3 hours
Working days per week = 5
Total work time per week :
3 1/3 * 5 = 10/3 * 5 = 50 / 3 hours
Time taken for styling and trimming :
1/4 + 1/6 = (3 + 2) / 12 = 5/12
Number of appointments stylist can schedule each week :
Total work time / time taken per person
(50 / 3) ÷ (5 / 12)
(50 /3) * (12 /5)
(50 * 12) / (3 * 5)
= 600 / 15
= 40

Follow these steps to construct a triangle to represent the given information:
Draw a ray in the direction S 20° E from point P. Create a circle with radius 43.5. (Note that you'll be scaling down all the distances in miles by a factor of 10: 435 ÷ 10 = 43.5.) Label the point where the circle intersects the ray as C (Cali).
Draw a ray in the direction S 81° E from P. Mark an arbitrary point on this ray, and label it S.
Create a line through point S that is parallel to the north-south line through P.
Using the line passing through point S, draw a ray that is S 53° W.
