Answer:

x = 4

Step-by-step explanation:

The parallel segment divides the 2 sides of the triangle proportionally, that is

$\frac{x}{8}$ = $\frac{6}{12}$ ( cross- multiply )

12x = 48 ( divide both sides by 12 )

x = 4

Answer:

the answer would be:

6/18 = x/x+8 => if you solve the equation, it'll be equal to : x = 4

I hope that it's correct.

Assume ABC Company deposits $90,000 with First National Bank in an account earning interest at 6% per annum, compounded and semi

Brilliant_brown [7]

Answer: A) $120,953

Step-by-step explanation:

The formula to calculate the compound amount (semi-annually):-

$A=P(1+\dfrac{r}{2})^{2n}$ , where P is principal amount , r is rate of interest and n is the number of time periods.

Given : Principal amount : P= $90,000

Rate of interest : 6% per annum = 0.06 per annum

Time period : n= 5 years

$A=(90000)(1+\dfrac{0.06}{2})^{2\times5}=120952.474141\approx 120,953$

Hence, the ABC will have $ 120,953 in the account after five years if interest is reinvested.

Explanation:

First, we need to find the values of the sine and cosine of x knowing the value of tan x and x being in the 3rd quadrant. Since tan x = 5/12, using Pythagorean theorem, we know that

$\sin x = -\frac{5}{13}\;\;\text{and}\;\;\cos x = -\frac{12}{13}$

Note that both sine and cosine are negative because x is in the 3rd quadrant.

Recall the addition identities listed below:

$\sin(\alpha + \beta) = \sin\alpha\sin\beta + \cos\alpha\cos\beta$

$\Rightarrow \sin(180+x) = \sin180\sin x + \cos180\cos x$

$\;\;\;\;\;\;= -\sin x = \dfrac{5}{13}$

$\cos(\alpha - \beta) = \cos\alpha \cos\beta + \sin\alpha \sin\beta$

$\Rightarrow \cos(180 - x) = \cos180\cos x + \sin180\sin x$

$\;\;\;\;\;\;=-\cos x = \dfrac{12}{13}$

$\tan(\alpha - \beta) = \dfrac{\tan\alpha - \tan\beta}{1 + \tan\alpha\tan\beta}$

$\Rightarrow \tan(360 - x) = \dfrac{\tan 360 - \tan x}{1 + \tan 360 \tan x}$

$\;\;\;\;\;\;= -\tan x = -\dfrac{5}{12}$

Therefore, the expression reduces to

$\sin(180+x) + \tan(360-x) + \frac{1}{\cos(180-x)}$

$\;\;\;\;\;= \left(\dfrac{5}{13}\right) + \left(\dfrac{5}{12}\right) + \dfrac{1}{\left(\frac{12}{13}\right)}$

$\;\;\;\;\;= \dfrac{49}{26}$
