What is the lead coefficient of the polynomial below?
3x^2+ 8x + 5
Answer:
The lead coefficient is 8
Step-by-step explanation:
This is because it is the biggest number that is right before the x or that is the coefficient.
The leading coefficient of the polynomial is given by C = 3
What is a polynomial?Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables involved.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the polynomial equation be represented as A
Now , the value of A is
A = 3x² + 8x + 5
On simplifying the equation , we get
The leading coefficient of a polynomial is the coefficient of the term with the highest degree. In this case, the polynomial 3x² + 8x + 5 has a term with degree 2 (the x² term) and the coefficient of that term is 3
Hence , the lead coefficient of this polynomial is 3

13. Your school is sponsoring a charity race. Which set of numbers best describes the number of people
who participate in the race?
a. Natural numbers
c. Rational numbers
b. Integers
d. Irrational numbers
Answer:c
Step-by-step explanation:
The set of numbers that best describes the number of people who participate in the race is given by: Option A: Natural numbers.
What are natural numbers, rational numbers, integers and irrational numbers?Natural numbers are: 1, 2, 3, .... Integer numbers are: ...., -2, -1, 0, 1, 2, ... (so it includes positive and negative natural number, and 0 )Rational numbers are numbers which can be written in the form of [tex]\dfrac{a}{b}[/tex]integers. Example: 1/2, 3.5 (which is writable as 7/5) etc.Irrational numbers are those real numbers which are not rational numbers. Example: [tex]\pi, \sqrt{2}[/tex] etc.Know that all natural numbers are integers, all integers are rational numbers. That means, natural numbers are not irrational.
The count of people participating in the race is going to be in integers, but only non-negative.
Actually the correct option would be 'whole numbers' (whole numbers are 0, 1, 2, ... so they include 0 in addition to natural numbers). It is because it may be that no one participates in the race.
But for the given condition, assuming that at least 1 person participates in the race, we deduce that the number of people participating in race is needed to be a natural number. (as people's count can't be negative, or in fractions, or irrational(which doesn't include integers at all) ).
Thus, the set of numbers that best describes the number of people who participate in the race is given by: Option A: Natural numbers.

A researcher reported that 71.8% of all email sent in a recent month was spam. A system large corporation believes that the percentage at his company may be 77 % . He manager at a examines a random sample of 500 emails received at an email server, and finds that 361 of the messages are spam.
Required:
Can you conclude that less than 77% of emails are spam?
Answer:
p-value = 0.0054
at 0.05 level of significance ∝
p-value ( 0.0054 ) is less than significance level ∝ ( 0.05 )
Thus we Reject Null hypothesis H₀
Hence, there is enough evidence to conclude that less than 77% of emails are spam.
Step-by-step explanation:
Given the data in the question;
Sample size n = 500
x = 361
p₀ = 77% = 0.77
q₀ = 1 - p₀ = 1 - 0.77 = 0.23
p = x / n = 361 / 500 = 0.722
Hypothesis;
Null hypothesis H₀ : p ≥ 77% or 0.77
Alternative hypothesis Hₐ : p ≥ 77% or 0.77
Test Statistic
z = ( p - p₀ ) / √( ( p₀ × q₀ ) / n )
so we substitute
z = ( 0.722 - 0.77 ) / √( ( 0.77 × 0.23 ) / 500 )
z = -0.048 / √( 0.1771 / 500 )
z = -0.048 / √0.0003542
z = -0.048 / 0.01882
z = -2.55
so our p-value will be;
p-value = p( z < -2.55 ) {from table }
p-value = 0.0054
at 0.05 level of significance ∝
p-value ( 0.0054 ) is less than significance level ∝ ( 0.05 )
Thus we Reject Null hypothesis H₀
Hence, there is enough evidence to conclude that less than 77% of emails are spam.

Answer:
Partitioning a line segment, AB, into a ratio a/b involves dividing the line segment into a + b equal parts and finding a point that is a equal parts from A and b equal parts from B. When finding a point, P, to partition a line segment, AB, into the ratio a/b, we first find a ratio c = a / (a + b).

A cone with a volume of 640.23 has a radius of 7. What is the height of the cone?
Please show work
Answer:
Your answer is about 12.48
Step-by-step explanation:
h = 3(V/pi*r²)
h = 3(640.23/pi*7²)
h = 3(640.23/153.93804)
h = 3(4.157516881)

y = 1 /2x
y = 1/2x -21
y = 1/2x – 10
y =1/2x + 11

[tex]slope \ of \ y = -2x + 11, m_{1} = -2\\\\Let \ the \ slope\ of \ the \ new \ line \ be \ m_{2} \\\\ Since \ the \ line \ is \ perpendicular \ to \ the\ given \ line, m_{1} \cdot m_{2} = -1\\\\-2 \cdot m _{2} = -1\\ \\m _{2} = \frac{1}{2} \\\\Equation \ of \ the \ line \ passing \ through (-6, 8) \ slope = \frac{1}{2} \\\\(y - y_{1}) = m_{2}(x-x_{2} )\\\\(y-8) =\frac{1}{2} (x-(-6))\\\\y -8 =\frac{1}{2} (x+6)\\\\y = \frac{1}{2}x +3 +8\\\\y =\frac{1}{2}x + 11[/tex]
