-5x^4y + 3x^2y + 4xy - 6y + 1 is descending order of it, the degree of the polynomial is 4 because the highest power is 4, but classifying it I do not know sorry gonna have to get someone else to answer that part

Find the critical numbers of the function. (Enter your answers as a comma-separated list. Use n to denote any arbitrary integer
AfilCa [17]

Answer:

\theta = \cos^{-1} (\pm \frac{1}{2} )

Step-by-step explanation:

The function is g(\theta) = 8\cdot \theta - 2\cdot \tan \theta, whose first derivative is:

g'(\theta) = 8 - 2\cdot \sec^{2}\theta

Let equalize the derivative to zero:

8 - 2\cdot \sec^{2}\theta=0

\sec^{2}\theta = 4

1 = 4\cdot \cos^{2}\theta

\cos \theta = \pm\sqrt {\frac{1}{4} }

\cos \theta = \pm \frac{1}{2}

The solutions are given by the following inverse trigonometric function:

\theta = \cos^{-1} (\pm \frac{1}{2} )

The base of a triangular prism is an isosceles right triangle with a hypotenuse of 72−−√ centimeters. The height of the prism is
Amiraneli [1.4K]

Answer:

Step-by-step explanation:

Surface area = lateral area + 2(area of base)

Lateral area = perimeter of base * height.

Because it is a isosceles right triangle, both sides are equal.

x^{2} +x^{2} = 72

2x^{2} = 72. Divide both sides by 2

x^{2} = 36.  Square both sides.

x = 6.

So the perimeter of the base = 6 + 6 +\sqrt{72} = 20.485281374239

Lateral area = 20.485281374239 * 7 = 143.397 cm^{2}

Area of base is (1/2)base * height.

(1/2)(6)(6) = 18

Using the surface area formula

surface area = 143.397 + 2(18) = 179.4 cm^{3}

Marilyn has two credit cards, D and E. Card D has a balance of $691. 64, and Card E has a balance of $1,014. 22. The minimum mon
elena-14-01-66 [18.8K]

By using basic concept of percentage we got that minimum payment on Card E is 0.77 than on Card D.

<h3>What is percentage ?</h3>

Percentage is a number or ratio expressed as a fraction of 100.

Here given that

Marilyn has two credit cards, D and E. Card D has a balance of $691. 64, and Card E has a balance of $1,014. 22. The minimum monthly payment on Card D is 3. 57% of the total balance, and the minimum monthly payment on Card E is 2. 51% of the total balance

So minimum balance of Card D is 3.57 Percentage  of $ 691.64

=3.54\times\frac{691.64}{100} =24.691548=24.69

minimum balance of Card E is  2. 51 Percentage  of  $1,014. 22.

=2.51\times\frac{1014.22}{100} =25.456922=25.46

Now we can see that minimum balance of Card E is 25.49-24.69=0.77 extra that on D

By using basic concept of percentage we got that minimum payment on Card E is 0.77 than on Card D.

Elise and her dad are planning to attend the state fair. An adult ticket is $21.00. The price of an adult ticket is $10.00 more
solong [7]

Answer:

C. two thirds x + 10 = 21

Step-by-step explanation:

Given

Price of adult ticket = $21.00

Let x be the price of student ticket

Then

two third of the student ticket will be:

\frac{2}{3} x

The statement $10.00 more than two third of student ticket:

\frac{2}{3} x+10

As we are given in the question that the adult ticket price is $21.00 and the second explanation is th equation formed by the given statement

So, both will be equivalent

\frac{2}{3} x+10 = 21

Solving this equation for x will give us the price for the student ticket.

Hence,

C. two thirdsx + 10 = 21 is the correct answer ..
