Select all the expressions that could represent the volume of a box, which is a third degree polynomial in variables x and y.
A. 3 x y − 3 x y^2
B 2y-xy^3+7
C.3x^3y^2-3x^2y+10y^2-10y
D. 3x^2y+5xy
E. 3y^3+3x^3y^4
Answer:
A and D
Step-by-step explanation:
Third degree polynomials refers to polynomials that has 3 as the greatest power of the variable.
A. 3 x y − 3 x y^2
Degree = 1 + 2 = 3
This option is correct
B 2y - xy^3 + 7
Degree = 1 + 3 = 4
This option is wrong
C. 3x^3y^2 -3x^2y + 10y^2 - 10y
Degree = 3 + 2 = 5
This option is wrong
D. 3x^2y+5xy
Degree = 2 + 1 = 3
This option is correct
E. 3y^3 + 3x^3 y^4
Degree = 3 + 4 = 7
This option is wrong

Considering only the values of [tex]\beta[/tex] for which [tex]\sin \beta \tan \beta \sec \beta \cot \beta[/tex] is defined, which of the following expressions is equivalent to [tex]\sin \beta \tan \beta \sec \beta \cot \beta[/tex]?
a. [tex]\sec \beta \cot \beta[/tex]
b. [tex]\tan \beta[/tex]
c. [tex]\cot \beta \tan \beta[/tex]
d. [tex]\tan \beta \csc \beta \sec \beta[/tex]
[tex]\large\boxed{Answer:}[/tex]
We will use trigonometric identities to solve this. I will use θ (theta) for the angle.
First of all, we know that cotθ = 1/tanθ. This is a trigonometric identity.
We can replace cotθ in the expression with 1/tanθ.
[tex]sin\theta tan\theta sec\theta \frac{1}{tan\theta}[/tex]
Simplify: 1/tanθ * tanθ = tanθ/tanθ = 1
So now, we have:
[tex]sin\theta sec\theta[/tex]
Next, we also know that secθ = 1/cosθ. This is another trigonometric identity.
We can replace secθ with 1/cosθ in our expression.
[tex]sin\theta \frac{1}{cos\theta}[/tex]
Simplify:
[tex]\frac{sin\theta}{cos\theta}[/tex]
Our third trigonometric identity that we will use is tanθ = sinθ/cosθ.
We can replace sinθ/cosθ with tanθ.
Now we have as our final answer:
[tex]\large\boxed{b.\ tan\theta}[/tex]
Hope this helps!

A label that wraps around a box of golf balls covers 75 percent of its lateral surface area. What is the value of x?
Answer:
To find the area of the rectangular prism, use the formula:
A = width x height x length
A = 2 x 2 x 3
A = 12
Now multiply A with 0.75
12 x 0.75 = 9
x = 9 in³

PLEASE HELP!! The AHS Football team did a weigh in at the start of training camp. The weights of the players were distributed normally with a mean of 98kg and a standard deviation of 6kg. Which of the following curves represents the data? A,B, Or C??
Answer: Choice C
=========================================================
Explanation:
The mean is 98, so that's the center of the distribution. This is where the highest point occurs because the most people are clustered around here. This rules out choice A and the answer is between B or C.
One standard deviation above the mean is 98+6 = 104. All we do is add on the standard deviation (6) to the mean (98) to get 104.
One standard deviation below the mean is 98-6 = 92
The graph that has tickmarks at 92 and 104 indicate we are exactly 1 standard deviation from the mean (98)
Similarly, 2 standard deviations above the mean is at 98+2*6 = 98+12 = 110. Or you could say 104+6 = 110.
2 standard deviations below the mean would get us to 98-2*6 = 98-12 = 86
The same idea applies to 3 standard deviations as well.
All of this matches with graph C. We can eliminate graph B by noticing that something like 95 is not a result of 98-6.
What is the area of the shaded region?
A. 3/5 sq ft
B. 5/16 sq ft
C. 5/24 sq ft
D. 3/20 sq ft
Answer:
B- 5/16 sq ft
Step-by-step explanation:
Their are 48 tiles total
15/48 are shaded so,
48 and 15 both go into 3,
15÷3= 5
48÷3=16
So then answer would be 5/16 sq ft

Answer:
Last option is the correct answer
Step-by-step explanation:
None of these choices are correct.
Correct order would be,
Since,
58° < 59° < 63°
Therefore,
AC < CB < AB
AC, CB, AB (this is the correct order of the sides from shortest to longest.)

this is a math question find the complement of 50 degree
Given:
The measure of an angle is 50 degrees.
To find:
The complement of the given angle.
Solution:
We know that the sum of an angle and its complement is 90 degrees.
Let x be the complement angle of 50 degrees.
[tex]x+50^\circ=90^\circ[/tex]
[tex]x=90^\circ-50^\circ[/tex]
[tex]x=40^\circ[/tex]
Therefore, the measure of complement of the given angle is 40 degrees.

Step-by-step explanation:
yesThe figure shown has two parallel lines cut by a transversal: A pair of parallel lines is shown, crossed by a transversal. Angles are identified as 1, 2, 3, 4, 5, 6, 7, and 8. Angles 1-4 are on the top line clockwise from upper left. Angles 5-8 are on the lower line clockwise from upper left. Use the figure to complete the sentence. ∠7 and ____ are alternate exterior angles. ∠2 ∠1 ∠5 ∠8
*see attachement for the diagram of the figure being referred to
Answer:
<1
Step-by-step explanation:
Alternate exterior angles are a pair of angles which are located on the opposite side of the transversal, outside the two parallel lines.
From the figure given, you would see that <7 and <1 lie on opposite side of the transversal and they lie on the outside of the two parallel lines that are cut across by the transversal.
Therefore:
<7 and <1 are alternate exterior angles.

Estimate the square root to the nearest (a) integer and (b) tenth
105
a. nearest integer.
b. nearest tenth
Answer:
a. nearest integer: -10
b. nearest tenth: -10.2
Step-by-step explanation:
The estimated integers are a) 10 and b) 10.2
(a) To estimate the square root of 105 to the nearest integer, we can use a rough approximation.
The square root of 100 is 10, and the square root of 121 is 11. Since 105 is closer to 100 than it is to 121, we can estimate the square root of 105 to be approximately 10.
(b) To estimate the square root of 105 to the nearest tenth, we can use a calculator or perform some calculations.
The square root of 105 is approximately 10.246950766. Rounded to the nearest tenth, we get 10.2.
Hence the estimated integers are a) 10 and b) 10.2

What number must you add to complete the square?
x2 + 16x = 3
O A. 16
B. 36
O C. 64
O D. 72
What number must you add to x² + 16x = 3 to complete the square 64: Option C
What is a perfect square?You should be aware that a perfect square is a term that has two common factors
The given equation is x² + 16x = 3
To make the equation a perfect square, Add the square of half of the coefficient of s to both sides
This is to say that (16/2)² = 8² = 64
The equation becomes x²+16x+64 = 3+64
Then you can factorize the equation and simplify the right hand side
