A. Sketch the curve by using the parametric equations to plot points. Indicate with an arrow the direction in which the curve is

Furkat [3]

Answer:

y = 2 - ( x - 1)²/9

Step-by-step explanation: See Annex

As the parameter t increases, the value of x increases and the value of y decreases, we get the figure of the annex ( the arrow in the Annex indicates the way of the curve with t increasing.

b) to eliminate the parameter:

x = 1 + 3*t (1) y = 2 - t² (2)

Then from equation (1) t = ( x - 1 ) / 3

plugging that value in equation (2)

y = 2 - [ ( x - 1 ) / 3 ]²

y = 2 - ( x² + 1 - 2*x)/9

9*y = 18 - x² + 1 - 2*x or y = 2 - ( x - 1)²/9

The curve is a parabol

What are the roots of x in -10x2 + 12x − 9 = 0?

hoa [83]

Answer:

$x_1=\frac{3(2+i\sqrt{6})}{10}$

$x_2=\frac{3(2-i\sqrt{6})}{10}$

Step-by-step explanation:

Use the Quadratic formula:

$x=\frac{-b\±\sqrt{b^2-4ac}}{2a}$

You can identify that, in this case:

$a=-10\\b=12\\c=-9$

Now you need to substitute these values into the formula:

$x=\frac{-12\±\sqrt{12^2-4(-10)(-9)}}{2(-10)}$

$x=\frac{-12\±\sqrt{-216}}{-20}$

Remember that:

$i=\sqrt{-1}$

Therefore,rewriting and simplifying, you get:

$x=\frac{-12\±6i\sqrt{6}}{-20}$

$x=\frac{-6(2\±i\sqrt{6})}{-2(10)}$

$x=\frac{3(2\±i\sqrt{6})}{10}$

Then, you get the following roots:

$x_1=\frac{3(2+i\sqrt{6})}{10}$

$x_2=\frac{3(2-i\sqrt{6})}{10}$
