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

Evaluate the expression for the given value of the variable. d=75 2d+−45d−−−−−√3=

Ahat [919]

Answer:

The expression for the given value of the variable d=75 is, 135

Step-by-step explanation:

Given the expression:

$2d+\sqrt[3]{-45d}$ ....[1]

We have to find the value for the given expression when d = 75

Substitute the value of d in [1] we have

$2(75)+\sqrt[3]{-45(75)}$

⇒ $150+\sqrt[3]{-3375}$

⇒ $150-15$

Simplify:

⇒ $135$

Therefore, the expression for the given value of the variable d=75 is, 135
