Answer:

n = 6

Step-by-step explanation:

\frac{ {5}^{n}  \times  {5}^{3} }{ {5}^{7} }  =  {5}^{2}  \\  \\  \implies \: \frac{ {5}^{n + 3}  }{ {5}^{7} } =  {5}^{2} \\  \\  \implies \:  {5}^{n + 3 - 7}  =  {5}^{2} \\  \\  \implies \:  {5}^{n  - 4}  =  {5}^{2} \\  \\  \implies \:n - 4 = 2 \\  \\   \implies \:n = 4 + 2 \\  \\  \implies \:n = 6

\qquad\qquad\huge\underline{{\sf Answer}}♨

Let's solve ~

\qquad \sf  \dashrightarrow \: \frac{5 {}^{n}  \times  {5}^{3} }{5 {}^{7} }  =  {5}^{2}

\qquad \sf  \dashrightarrow \: \frac{5 {}^{n + 3}    {}^{} }{5 {}^{7} }  =  {5}^{2}

\qquad \sf  \dashrightarrow \:5 {}^{n + 3 - 7} =  {5}^{2}

\qquad \sf  \dashrightarrow \:5 {}^{n - 4} =  {5}^{2}

\qquad \sf  \dashrightarrow \:{}{n - 4} =  {2}

\qquad \sf  \dashrightarrow \:n = 2 + 4

\qquad \sf  \dashrightarrow \:n = 6

Hence, value of n is 6

Answer:

<h2>8</h2>

Step-by-step explanation:

Hypotenuse = 8\sqrt{2} \\Adjacent =x\\\alpha =45\\\\Using\: SOHCAHTOA\\Cos \alpha = \frac{Adjacent}{Hypotenuse}\\\\Cos 45 = \frac{x}{8\sqrt{2} } \\\frac{\sqrt{2} }{2} =\frac{x}{8\sqrt{2} }\\ \\Cross \: Multiply\\2x =16\\\frac{2x}{2} =\frac{16}{2} \\\\x =8

Factor the trigonometric equation.<br> cos2x-cosx
prisoha [69]

Cos(2x) = cos^2(x) - sin^2(x) - cos(x)

but sin^2(x) = 1 - cos^2(x)

cos(2x) - cos(x) = cos^2(x) - (1 - cos^2(x) ) - cos(x)

cos(2x) - cos(x) = cos^2(x) - 1 + cos^2(x) - cos(x)

cos(2x) - cos(x) = 2cos^2(x) - 1 - cos(x)

cos(2x) - cos(x) = (2cos(x) + 1)(cos(x) - 1)

I think this is what you have asked for.

Write the terms a 1a1​, a 2a2​, a 3a3​, and a 4a4 of the following sequence. If the sequence appears to​ converge, make a conjec
Arturiano [62]

Answer:

Step-by-step explanation:

WE are given that a_n = \frac{(-1)^{n+1}}{5n-4}. Then, to now the first for terms, we must replace n by 1,2,3,4 respectively. Then

a_1 = \frac{(-1)^2}{5(1)-4} = \frac{1}{1}= 1

a_2 = \frac{(-1)^3}{5(2)-4} = \frac{-1}{6}

a_3 = \frac{(-1)^4}{5(3)-4} = \frac{1}{11}= 1

a_4 = \frac{(-1)^5}{5(4)-4} = \frac{-1}{16}= 1

Note that as n increase, a_n gets closer to 0. So, the limit of this sequence is 0.

1. round the result to 2 decimal places. -0.9x+2.8=4.1
lora16 [44]
1. <span>-0.9x+2.8=4.1
First subtract 2.8 from both sides.
-0.9x = 1.3
Now divide both sides by -0.9.
x = -1.4444..
This can be rounded to -1.44
