Answer:

9x^2+4y^2=36

Step-by-step explanation:

We are given that

x=2cos t

y=3 sin t

0\leq t\leq 2\pi

cost=\frac{x}{2}

sint=\frac{y}{3}

sin^2 t+cos^2 t=(\frac{x}{2})^2+(\frac{y}{3})^2

1=\frac{x^2}{4}+\frac{y^2}{9}

By using the formula

sin^2\theta+cos^2\theta=1

1=\frac{9x^2+4y^2}{36}

9x^2+4y^2=36

Divide x cubed minus 3 x squared minus 10 x + 24 by x minus 2. Step 1 - Fill in the missing number: A vertical line and horizont
wariber [46]

The value of k is 2 if the polynomial x³ - 3x² - 10x + 24 is divided by the expression (x - 2).

<h3>What is synthetic division?</h3>

In the case of dividing by a linear factor, the synthetic division is a shorthand, or quicker, a technique of polynomial division.

The question is attached to the picture please refer to the picture.

We have a polynomial:

x³ - 3x² - 10x + 24

Which is divided by (x - 2)

We can divide using the synthetic division:

The first row: 1   -3   -10   24

The entry outside the row: 2

The missing value which is 2

k = 2

Thus, the value of k is 2 if the polynomial x³ - 3x² - 10x + 24 is divided by the expression (x - 2).
