Answer: x= 23/2 or 11.5
Work: Step 1) 3(x-2)2-37=20
Step 2) (3x-6)2-37=20
Step 3) 6x-12-37=20
Step 4) 6x-12= 20+37
Step 5) 6x=57+12
Step 6) 6x=69
Step 7) x=69/6
Step 8) x= 23/2

Identify the parametric equations that represent the same path as the following parametric equations.

Nady [450]

In mathematics, a parametric equation defines a group of quantities as functions of one or more independent variables called parameters. Generally this parameter is given by t. This type of equations are commonly used to express the coordinates of the points that make up a geometric object like a curve or surface, in which case the equations are collectively called a parametric representation or parameterization. In the figures below, the equation:

$\left \{ {{x(t)=2cos2t} \atop {y(t)=sin3t}} \right.$

matches with this one:

$\left \{ {{x(t)=2cos4t} \atop {y(t)=sin6t}} \right.$

(x sin a + y cos a)^2 + (x cos a – y sin a)^2 = x^2 + y^2

kobusy [5.1K]

Answer:

Proved

Step-by-step explanation:

Required

Prove that:

$(x\ sin\ a + y\ cos\ a)^2 + (x\ cos\ a - y\ sin\ a)^2 = x^2 + y^2$

Solving from left to right:

Open brackets

$(x\ sin\ a + y\ cos\ a)(x\ sin\ a + y\ cos\ a) + (x\ cos\ a - y\ sin\ a)(x\ cos\ a - y\ sin\ a) = x^2 + y^2$ $x^2\ sin^2 a + 2xy\ sin\ a\ cos\ a + y^2\ cos^2 a + x^2\ cos^2 a - 2xy\ sin\ a\ cos\ a + y^2\ sin^2 a = x^2 + y^2$
