WILL GIVE BRAINLIEST PLEASE HELP Write the equation and show work. Find 'x" and ' TK'

Mathematics
1 answer:
marishachu [46]3 years ago
4 0

Answer:

x=6

TK=72

Step-by-step explanation:

Because there are two smaller lines drawn in lines TA and AK, it means that the length of TA is the same as AK.

Hence, 6x=4x+12

Subtract 4x from both sides:

6x-4x=4x+12-4x

2x=12

Divide both sides by 2:

\frac{2x}{2}=\frac{12}{2}

x=6

To find TK,

6x+4x+12=10x+12=10\times 6+12=60+12=72

What is the annual interest rate is 1=$160.67, p=$2000, t=8 months
Sergeeva-Olga [200]
Please use " i " to denote "interest."

the formula for simple interest is i = p r t.

Here, i = $160.67 = $2000 (r) (8/12)


Solving for the interest rate, r = ($169.67)(12/8)/ $2000 = 0.127, or 12.7%

The series is a convergence series and the sum of the series is -8/3

<h3>The type of the series</h3>

The series is given as:

\sum\limits^{\infty}_{n = 1} -4(-\frac 12)^{n-1}

The above series has the following properties:

  • First term; a = -4
  • Common ratio, r = -1/2

Start by calculating the absolute value of the common ratio

Absolute value = |-1/2|

This gives

Absolute value = 1/2

The above value is less than 1.

It means that the series converges.

<h3>The sum of the series</h3>

This is calculated using:

S_{\infty} = \frac{a}{1 -r}

So, we have:

S_{\infty} = \frac{-4}{1 + \frac 12}

Evaluate the sum

S_{\infty} = \frac{-4}{\frac 32}

Evaluate the quotient

S_{\infty} = \frac{-8}{3}

Hence, the sum of the series is -8/3
