Okay, my prior answer got deleted for no work, apparently.
I'll re-post it though.

That word problem translates to:
$8n -4=0 \\ +4 \\ \\ 8n=4 \\ /8 \\ \\ n=1/2$

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

A cement block is in the shape of a rectangular prism that measures 4.5 feet by 7.25 feet by 6.5 feet. The entire block must be

Simora [160]

Since A=l*w*h,

A=4.5*7.25*6.5
A=212.0625

A=212.0 feet squared is the answer.
