Have A Good Day :)
Given:
The given expression is:
![(-4x+9)^2](https://tex.z-dn.net/?f=%28-4x%2B9%29%5E2)
According to Kylie,
![(-4x+9)^2=(-4x)^2+(9)^2](https://tex.z-dn.net/?f=%28-4x%2B9%29%5E2%3D%28-4x%29%5E2%2B%289%29%5E2)
![(-4x+9)^2=16x^2+81](https://tex.z-dn.net/?f=%28-4x%2B9%29%5E2%3D16x%5E2%2B81)
To find:
The correct statement for Kylie's explanation.
Solution:
We have,
![(-4x+9)^2](https://tex.z-dn.net/?f=%28-4x%2B9%29%5E2)
According to the perfect square trinomial
.
![(-4x+9)^2=(-4x)^2+2(-4x)(9)+(9)^2](https://tex.z-dn.net/?f=%28-4x%2B9%29%5E2%3D%28-4x%29%5E2%2B2%28-4x%29%289%29%2B%289%29%5E2)
![(-4x+9)^2=16x^2-72x+81](https://tex.z-dn.net/?f=%28-4x%2B9%29%5E2%3D16x%5E2-72x%2B81)
Kylie did not understand that this is a perfect square trinomial, and she did not determine the product correctly.
Therefore, the correct option is C.
Answer:
<h2><u>16840.8</u></h2>
Step-by-step explanation:
In mathematics, the discount is a type of reduction in the cost price of a product. Generally, the discount refers to the condition where the selling price of the product is less than the cost price of the product. The discount can be calculated by taking the difference between the cost price and the selling price. Thus, the formula to determine the discount is given as:
Discount = Cost price – Selling Price

The tangent line to the curve can be determined by implicitly differentiating the equation of the curve. In this case, with the equation <span>y sin 12x = x cos 2y, (π/2, π/4), the implicit differentiation is 12 y cos 12x dx + sin 12 x dy = -2x sin 2y dy + cos 2y dx; dx (12 y cos 12x - cos 2y) = dy (</span><span>-2x sin 2y - sin 12x). Hence
y' = (</span>12 y cos 12x - cos 2y) / (<span>-2x sin 2y - sin 12x)</span>
7.846 decomposed is:
7 + 0.8 + 0.04 + 0.006
or, to see it more clearly:
7.000 + 0.800 + 0.040 + 0.006
Rounded to the nearest tenth: 7.8
Rounded to the nearest hundredth: 7.85
I hope that's what you meant :)
