Eliminate the parameter in the equations x = and y = t – 4. How can the rectangular equation be described? cubic linear quartic

BigorU [14]

Answer:

Step-by-step explanation:

If $x = t^{1/3}$ , then $t=x^{3}$

Now, puting $t$ value in the other equation, we have

$y=x^{3} - 4$

Therefore, is a cubic equation

THE MEASURE OF TWO ADJACENT ANGLES OF THE PARALLELOGRAM ARE IN THE RATIO OF 3:2. FIND THE MEASURE OF EACH OF THE ANGLES OF THE P

BaLLatris [955]

Answer:

The adjacent angles are: 72 and 108

Step-by-step explanation:

Given

Angle Ratio = 3 : 2

Required

Find the measure of each angle

Let the angles be $x\ and\ y.$

Such that:

$x + y = 180$ --- adjacent angles of a parallelogram

and

$x : y = 3 : 2$ --- given

Convert to fraction

$\frac{x}{y} = \frac{3}{2}$

Cross Multiply:

$2x = 3y$

Make x the subject:

$x = \frac{3}{2}y$

$x + y = 180$ becomes

$\frac{3}{2}y + y = 180$

Take LCM

$\frac{3y + 2y}{2}= 180$

$\frac{5y}{2}= 180$

$y = \frac{2}{5} * 180$

$y = 0.4 * 180$

$y = 72$

Recall that:

$x = \frac{3}{2}y$

$x = \frac{3}{2} * 72$

$x = 1.5 * 72$

$x = 108$

Hence, the adjacent angles are: 72 and 108

A regular heptagon has an apothem of approximately 6.7 cm and a perimeter of approximately 45.5 cm.

Maurinko [17]

Answer:

304.85 cm²

Step-by-step explanation:

The area (A) of a polygon is calculated as

A = pa ( p is the perimeter and a the apothem ) , thus

A = 45.5 × 6.7 = 304.85 cm²
