Find an expression for the area enclosed by quadrilateral ABCD below.

Helga [31]

∆ABD is right angled hence area:-

$\\ \sf\longmapsto \dfrac{1}{2}bh$

$\\ \sf\longmapsto \dfrac{1}{2}(4x)(3x)$

$\\ \sf\longmapsto \dfrac{1}{2}(12x^2)$

$\\ \sf\longmapsto 6x^2$

There is only one option containing 6x^2 i.e Option D.

Hence without calculating further

Option D is correct

How much will the monthly payment be for a new car priced at $14,350 if the current finance rate is 36 months at 3. 16%? Include

expeople1 [14]

The monthly payment for the new car is; Choice A; $279. 03

<h3>Percentages</h3>

After the down payment of 30% and financing the 8% TT&L is made; it follows that;

The rest of the payment is;

$14,350(1 - 0.38)

$14,350(0.62)

Hence, $8,897 is the payment made over the course of the duration at a finance rate of 3.16%.

Ultimately, the monthly payment is; $8,897 × 0.0316 = $279.03

Simplify sin^2y/sec^2 y−1 to a single trigonometric function

liubo4ka [24]

Answer:

$\frac{ { \sin}^{2} y}{ { \sec}^{2}y - 1 } = { \cos }^{2} y$

Step-by-step explanation:

We know that ${ \tan }^{2} y = { \sec }^{2} y - 1$

Also , ${ \tan}^{2} y = \frac{ { \sin }^{2} y}{ { \cos }^{2}y }$

So ,

$\frac{ { \sin }^{2}y }{ { \sec }^{2}y - 1 } = \frac{ { \sin}^{2} y}{ { \tan }^{2} y} = \frac{ { \sin }^{2}y }{ \frac{ { \sin}^{2} y}{ { \cos}^{2}y } } = { \cos }^{2} y$
