It is in standard form because the exponents are in order from highest to lowest.
The given polynomial is [tex]-24x^{7} -12x^{2} -9x+6[/tex].
We need to determine from the given statements, which statement best describes the given polynomial.
What is the standard form of the polynomial?The highest degree of terms is written first, followed by the next degree, and so on, to represent a polynomial in standard form. The standard form of the polynomial is [tex]f(x)=a_{n} x^{n} +a_{n-1} x^{n-1}+a_{n-2} x^{n-2} +........a_{1}x+a_{0}[/tex].
So, in the given polynomial [tex]-24x^{7} -12x^{2} -9x+6[/tex], the exponents of the variable are in decreasing order.
Therefore, it is in standard form because the exponents are in order from highest to lowest.

HOPE IT HELPS.BRAINLIESTPaint can be purchased in two sizes: 1 gallon for $45.99 or 1 quart for $14.99.(round to the hundredths place)a.unit ratio of 1 quart (32oz) for $14.99is __________b.unit ratio of 1 gallon (128oz) for $45.99is __________c.which is the better deal?
Answer:
a. $0.47 per ounce
b. $0.36 per ounce
c. the gallon size costs less per ounce
Step-by-step explanation:
A unit rate is a rate that is expressed with one unit in the denominator. That is, it is <some amount> per unit. The <some amount> value will generally depend on what unit is chosen. This problem suggests the desired unit is 1 oz of paint.
__
a.Unit cost for a quart:
ratio = cost/ounces = $14.99/(32 oz) ≈ $0.468/oz ≈ $0.47/oz
__
b.Unit cost for a gallon:
ratio = cost/ounces = $45.99/(120 oz) ≈ $0.359/oz ≈ $0.36/oz
__
c.The cost per ounce is less for the gallon size. If at least 3 quarts of paint is needed, then buying it in the gallon size will cost less.
If less than 3 quarts are needed, then a gallon container will cost more than is necessary for the paint required. The "better deal" depends on the amount of paint required.

The mean test score of 12 students is . 42
A student joins the class and the mean becomes .43
Find the test score of the student who joined the class.
Answer:
45 becasue it has to be over 43
Step-by-step explanation:
The test score of the student who joined the class will be;
⇒ 55
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The mean test score of 12 students = 42
And, A student joins the class and the mean becomes 43.
Now,
Total score for 12 students is,
⇒ x / 12 = 42
⇒ x = 42 × 12
⇒ x = 504
Here, A student joins the class and the mean becomes 43.
Let the student who join = y
So, We get;
⇒ (504 + y) / 13 = 43
⇒ 504 + y = 43× 13
⇒ 504 + y = 559
⇒ y = 559 - 504
⇒ y = 55

The probability that the book is nonfiction given that it is hard-covered is 4/11
How to determine the probability?From the complete question, we have:
Total = 20
n(H ∩ N) = 4
n(H) = 11
This means that:
P(H ∩ N) = n(H ∩ N)/Total
So, we have:
P(H ∩ N) = 4/20
The conditional probability is then calculated using:
P(N | H) =4/20 ÷ 11/20
Evaluate
P(N | H) = 4/11
Hence, the probability that the book is nonfiction given that it is hard-covered is 4/11

The slope of a line is 3. The y intercept of the same line is -12
Complete the slope intercept form equation
Answer:

m = slopeb = y-interceptSubstitute m = 3 and b = -12 in the equation :
y = 3x - 12Answer:
y = 3x - 12
Step-by-step explanation:
The slope intercept form of a line is y = mx + b, where m is the slope and b is the y intercept. Here, m = 3 and b = -12. Therefore, the slope intercept form for this line is y = 3x - 12.

Answer:
[tex](x+5)^2+y^2=117[/tex]
Step-by-step explanation:
Equation of a circle
[tex](x-a)^2+(y-b)^2=r^2[/tex]
(where (a, b) is the center and r is the radius)
Given:
center = (-5, 0)[tex]\implies (x-(-5))^2+(y-0)^2=r^2[/tex]
[tex]\implies (x+5)^2+y^2=r^2[/tex]
To find r², input the coordinates of the given point (4, -6) into the equation:
[tex]\implies (4+5)^2+(-6)^2=r^2[/tex]
[tex]\implies 81+36=r^2[/tex]
[tex]\implies r^2=117[/tex]
Therefore, the equation of the circle is:
[tex]\implies (x+5)^2+y^2=117[/tex]
Answer:
Standard form = (x + 5)² + y² = 117

The measure of the missing angle x is 23.22 degrees
Cosine ruleThe expression for representing cosine rule is expressed as:
c² = a² + b² - 2ab cos C
Given the following parameters
a = 26

c² = a² + b² - 2ab cos C
29² = 26² + 50² - 2(26)(50) cos C

three numbers are in the ratio 1:3:5 and their sum is 270. find the largest number.
Answer:
150
Step-by-step explanation:
Let :
⇒ The numbers can be denoted as x, 3x, and 5x
=============================================================
Solving :
⇒ It mentions their sum is 270
⇒ x + 3x + 5x = 270
⇒ 9x = 270
⇒ x = 30
=============================================================
Largest number :
⇒ 5x
⇒ 5(30)
⇒ 150
Answer :
Largest number is 150.Step by step explaination :
Here we have been given with the ratio of three numbers that is 1 : 3 : 5. So let us assume a common factor for them , we are assuming it as y.
Therefore,
First number = 1 → 1 × y = 1y Second number = 3 → 3 × y = 3yThird number = 5 → 5 × y = 5ySum of them is 270 :
>> 1y + 3y + 5y = 270
>> 4y + 5y = 270
>> 9y = 270
>> y = 270 / 9
>> y = 90 / 3
>> y = 30
Henceforth, value of y is 30.
★ Finding out first number :-
>> First number = 1y
>> First number = 1 × 30
>> First number = 30
★ Finding out second number :-
>> Second number = 3y
>> Second number = 3 × 30
>> Second number = 90
★ Finding out third number :-
>> Third number = 5y
>> Third number = 5 × 30
>> Third number = 150

Leah's family took a road trip to Mount Rushmore. Leah fell asleep 44% of the way through the trip. If Leah fell asleep after they had travelled 132 miles, what was the total length of the trip?
How you do it is add the 44% of 132 to 132 (132 + (132×44%))
First you have to find out how much 44% is. Change it into decimal form (0.44) and then multiply the two together. 132 × 0.44 is 58.08 miles. Then you add that to the rest of the trip, 132 miles. (132 + 58/08 is 190.08)

The value of x is 6.
What are complementary?Complementary angles are angles that sum up to 90°.
Analysis:
For angles A and B, to be complementary, the sine of angle A must be equal to the cosine of angle B.
sin A = cos B
5X+9 = 3x+21
