14 cm

sukhopar [10]

Answer:

D. 216 cm

Step-by-step explanation:

1. I assume 14 is a 22 is b and 12 is h

2. Trapezoid Area Formula

$A = \frac{1}{2}(a+b)h$

3. Plug in numbers

$A = \frac{1}{2}(14+22)12$

$216 = \frac{1}{2}(14+22)12$

The y-value of y = tan(x) when x = -90° and x = 90° is 0.<br><br> True<br><br> False

Lyrx [107]

We know, Tanx = sinx / cosx
Tan 90 = sin90 / cos 90
Tan 90 = 1/0

As zero is in the denominator, it can't be defined.

In short, Your Answer would be: "False"

Hope this helps!

The parametric curve described by the equations x=\cos(t),\;\;y=\sin(t)\cos(t) has two tangent lines at (0, 0). find the equatio

mr Goodwill [35]

Hello,

$x=cos(t)==\ \textgreater \ \dfrac{dx}{dt} =-sin(t)\\
y= \dfrac{sin(2t)}{2}==\ \textgreater \ \dfrac{dy}{dt} =cos(2t)\\

 \dfrac{dy}{dx} = \dfrac{ \frac{dy}{dt}}{ \frac{dx}{dt} } =- \frac{cos(2t)}{sin(t)} \\
For\ x=0, \ t=cos(0)= \frac{ \pi }{2} +k \pi \\

( \dfrac{dy}{dx} )_{x=0} =\pm\ 1\\

tangents \ are\ \{ y=-x,y=x \}\\
