The Cartesian equation of the curve is 4x² + 3y² = 36.

We can eliminate the parameter θ by using the trigonometric identity cos²(θ) + sin²(θ) = 1, which gives us:

x²/9 + y²/16 = cos²(θ) + sin²(θ) = 1

Multiplying both sides by 16 to get rid of the fraction, we have:

16(x²/9 + y²/16) = 16

4x² + 3y² = 36

Therefore, the Cartesian equation of the curve is 4x² + 3y² = 36.

The Cartesian equation 4x² + 3y² = 36 represents an ellipse centered at the origin with semi-axes lengths of 2√3 and 2√2. The standard form for the equation of an ellipse centered at the origin is:

(x²/a²) + (y²/b²) = 1

where a and b are the semi-axes lengths of the ellipse. To convert the given equation to this standard form, we need to divide both sides by 36:

(4x²/36) + (3y²/36) = 1

Simplifying:

x²/9 + y²/12 = 1

Comparing with the standard form, we have:

a² = 9 and b² = 12

Therefore, the semi-axes lengths are √9 = 3 and √12 ≈ 3.464.

So, the equation 4x² + 3y² = 36 represents an ellipse centered at the origin with semi-axes lengths of 3 and approximately 3.464.

Step-by-step explanation:

Using the known Maclaurin series expansion for e^x: e^x = 1 + x + (x^2 / 2!) + (x^3 / 3!) + ...

We can obtain the Maclaurin series for the function f(x) = xe^(7x) by multiplying the Maclaurin series for e^x by x:

f(x) = x(1 + 7x + (7x)^2 / 2! + (7x)^3 / 3! + ...)

Simplifying further:

f(x) = x + 7x^2 + (49x^3 / 2!) + (343x^4 / 3!) + ...

Therefore, the Maclaurin series expansion for f(x) is:

f(x) = x + 7x^2 + (49x^3 / 2!) + (343x^4 / 3!) + ...

The associated radius of convergence, R, can be determined by applying the ratio test. In this case, we have an infinite power series with terms involving powers of x. The ratio test states that if the limit of |a_(n+1) / a_n| as n approaches infinity is L, then the radius of convergence is R = 1 / L.

In our case, applying the ratio test yields a limit of 0 as n approaches infinity. Therefore, the radius of convergence R is infinite, indicating that the Maclaurin series for f(x) converges for all values of x.

Answer: Since her art and music sections each only had half the number of sheets of paper as a core subject, together the two sections had the same amount of paper as a core subject. Therefore, it is almost like her notebook had five core subjects, rather than four core subjects and two electives. If she divided the 200 sheets equally among the five core subjects, there would be 200 ÷ 5 = 40 sheets in each section. Now we can see that art would actually have half of this amount, or 20 sheets of paper.

Answer:

3x+y=13

+2x-y=12

SOlve it like what you would normally do

3x+2x=5x

y+(-y)=0

13+12=25

Basically

5x+0=25

Bring down all appropiate signs

Now solve that

5x=25

x=5

Now to find “y”

Plug in The “x”

3*5=15

15+y=13 now solve that and you’d get -2

If you plug it into the other one, it would be the same thing

2*5=10

10-y=12

-y=2

y= -2

x=5

y= -2

The solution to the linear congruence 2x + 6 ≡ 4 (mod 8) is x ≡ 3 (mod 8).To solve the linear congruence 2x + 6 ≡ 4 (mod 8), we need to find the values of x that satisfy the congruence equation.

First, let's simplify the equation:

2x + 6 ≡ 4 (mod 8)

Subtracting 6 from both sides:

2x ≡ 4 - 6 (mod 8)

2x ≡ -2 (mod 8)

Next, we can simplify -2 (mod 8) by adding 8 to it:

-2 ≡ 6 (mod 8)

Now the congruence equation becomes:

2x ≡ 6 (mod 8)

To solve for x, we need to find the multiplicative inverse of 2 modulo 8. The multiplicative inverse of 2 is 4, as 2 * 4 ≡ 1 (mod 8).

Multiplying both sides of the congruence equation by 4:

4 * 2x ≡ 4 * 6 (mod 8)

8x ≡ 24 (mod 8)

Simplifying the equation:

8x ≡ 24 (mod 8)

x ≡ 3 (mod 8)

Therefore, the solution to the linear congruence 2x + 6 ≡ 4 (mod 8) is x ≡ 3 (mod 8).

Answer:

4 pounds 12 ounces

Step-by-step explanation:

there are 16 ounces in 1 pound so 76/16 = 4.75 and .75 is equal to 12 ounces.

76 ounces is equal to 4 pounds and 12 ounces.

To convert 76 ounces to pounds and ounces, we need to consider that 1 pound is equal to 16 ounces.

Here's how to proceed:

Divide the total number of ounces by 16 to find the number of pounds:

76 ounces ÷ 16 ounces/pound = 4.75 pounds

Since 4 pounds = 4 x 16 pounce/ pound

= 64 ounces ,we subtract this amount from the total of 76 ounces to determine the remaining ounces:

= 76 ounces - 64 ounces

= 12 ounces

Therefore, 76 ounces is equal to 4 pounds and 12 ounces.

Answer:

a. 8 years

b. $49.20

Step-by-step explanation:

The computation is shown below:

a. The mark age is

Given that

232 is 8 times of the sum of mark and his sister ages

And, his sister is 21

So,

Let us assume the mark age be x

now

8(x + 21) = 232

x + 21 = 29

x = 29 -21

x = 8

b. The original price of the socks is

As each pair get $3 off

And she bought 6 pairs for $31.20

= $31.20 + 6 × $3

= $31.20 + 18

= $49.20
