Find a rectangular equation. X = 3tan t, Y = 2sec t, for in (−π /2 , π /2 )

anzhelika [568]

Answer:

Step-by-step explanation:

$x= 3tan(t) \rightarrow tan(t) = \frac{x}{3} \rightarrow tan^2(t) = \frac{x^2}{9}$

$y= 2sec(t) \rightarrow sec(t) = \frac{y}{2} \rightarrow sec^2(t) = \frac{y^2}{4}$

$sec^2(t) -tan^2(t) =1$

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

is the rectangular equation of the parameter functions.

also, it is a hyperbola. The condition $-\pi/2 < t$ limit x from 0 to infinitive

David has a loyalty card good for a 19% discount at his local hardware store. What would his total in dollars and cents be, afte

Elina [12.6K]

Discounts are used to reduce the original price of an item.

David will pay $25 and 92 cents for an item of $32, before tax

The discount (d) is given as:

$d =19\%$

The price (p) of the item is given as:

$p = \$32$

So, the amount (A) paid before tax is calculated using:

$A = p \times (1 - d)$

Substitute known values

$A = \$32 \times (1 - 19\%)$

Express percentage as decimal

$A = \$32 \times (1 - 0.19)$

Subtract 0.19 from 1

$A = \$32 \times 0.81$

Multiply 32 and 0.81

$A = \$25.92$

Hence, David will pay $25 and 92 cents for an item of $32, before tax
