((2x^9)(y^n))((4x^2)(y^10))=(8x^11)(y^20)

tino4ka555 [31]

We are given

$((2x^9)(y^n))((4x^2)(y^{10}))=(8x^{11})(y^{20})$

Firstly, we simplify left side

Left side is

$((2x^9)(y^n))((4x^2)(y^{10}))$

we will make all x terms together

and y terms together

$(2x^9)(4x^2)(y^n)(y^{10})$

$2\times 4(x^9)(x^2)(y^n)(y^{10})$

$8(x^9)(x^2)(y^n)(y^{10})$

we can multiply left side by using exponent rule

$a^m\times a^n=a^{m+n}$

$8(x^{9+2})(y^{n+10})$

$8(x^{11})(y^{n+10})$

now, we can set them equal

$(8x^{11})(y^{n+10})=(8x^{11})(y^{20})$

Since, both sides have x,y and 8

and both are equal

so, their exponent must be equal

so, exponent of y must also be equal

we get

$n+10=20$

Buying a $36,000 new hybrid SUV with $3000 paid up front and the rest borrowed at 4.2%

Studentka2010 [4]

From the calculations, the total amount paid for the SUV is $43,708.

<h3>What is compound interest?</h3>

The term compound interest has to do with an interest that is charged in both the principal and the interest.

In this case, the amount that was borrowed is $36,000 - $3000 = $33,000. Using the formula;

A = P(1 + r/n)^nt

P = $33,000

r = 4.2%

n = 52

t = 5 years

A = 33,000(1 + 0.042/52)^(52 * 5)

A = $40,708

Total amount paid = $40,708 + $3000 = $43,708

Three trigonometric functions for a given angle are shown below. cosecant theta = thirteen-twelfths; secant theta = Negative thi

Kay [80]

Answer:

(–5, 12) is the correct answer.

Step-by-step explanation:

We are given the following values:

$cosec\theta = \dfrac{13}{12}\\sec\theta=-\dfrac{13}{5}\\cot\theta =-\dfrac{5}{12}$

Now, we know the following identities:

$sin \theta = \dfrac{1}{cosec\theta}\\cos \theta = \dfrac{1}{sec\theta}\\tan \theta = \dfrac{1}{cot\theta}$

Now, the values are:

$sin\theta = \dfrac{12}{13}\\cos\theta=-\dfrac{5}{13}\\tan\theta =-\dfrac{12}{5}$

Sine value is positive and cos, tan values are negative.

It can be clearly observed that $\theta$ is in 2nd quadrant.

2nd quadrant means, the value of $x$ will be negative and $y$ will be positive.

Let us have a look at the value of $tan\theta$ :

$tan\theta = \dfrac{Perpendicular}{Base}\\OR\\tan\theta = \dfrac{y-coordinate}{x-coordinate} = -\dfrac{12}{5}\\\therefore y = 12,\\x = -5$

Please refer to the attached image for clear understanding and detailed explanation.

Hence, the correct answer is coordinate (x,y) is (–5, 12)
