Answer:

C) 12.5

The length of BC = 12.5cm

Step-by-step explanation:

Step(i):-

Given that ΔABC

Given that AB = 15cm and ∠A = 40°

we will use trigonometric function

$tan x = \frac{oppositeside}{adjacentside}$

$tan 40^{0} = \frac{BC}{AB} = \frac{BC}{15}$

Step(ii):-

we know that tan40° = 0.83909

$tan 40^{0} = \frac{BC}{15}$

BC = 15 × tan 40°

BC = 12.58649

BC = 12.5cm

Final answer:-

The length of BC = 12.5cm

Would you prefer a fully taxable investment earning 8.1 percent or a tax-exempt investment earning 6.1 percent

Sindrei [870]

Answer:

Assuming that all other factors are equal, (and they never are), I would prefer a 20% or more ROI investment, located in a tax deferred, or tax exempt account!

Assuming that you are for some reason entirely unmotivated to look for better investments than the two you have pointed out, why not just buy the 8.1% investment with your IRA, Roth IRA, 401(k), SEP IRA, or spousal IRA funds?

You can then pretty much ignore your tax rate. Just move over any portion of your standard deduction that remains unused near the end of the year, via a Roth conversion. You will pay no additional taxes, and the money converted will forever remain free of RMDs, (which will otherwise occur later on), for the rest of your life!

Step-by-step explanation:

Use your now freed up taxable money to invest in tax free transactions, (similar to the effect of having a periodic Roth IRA), and live happily ever after!

As always, upvote and follow me, either if you are entertained by my answers, or, if you are sufficiently curious to investigate my other answers posted on Quora, and realize that you COULD be making FAR MORE money with your investments than you have been!

Thank you for reading and I hope it helps

Which of the following statements would be the process that is used to describe solving a system of equation with 6 variables?

Karolina [17]

I think the correct answer from the choices listed above is the second option. Solving a 6 order system would be the process that is used to describe solving a system of equation with 6 variables. The number of variables should be equal to the order of the system for it to be solved. Hope this answers the question.

Not drawn

Nady [450]

First find the areas of the two separate rectangles where:

Area of rectangle = length x width

Area of the small rectangle = x(x–4)

Area of small rectangle = $x^{2} -4x$

Area of big rectangle = (x–2)(2x+x)

Area of big rectangle = (x–2)(3x)

Area of big rectangle = $3x^{2} -6x$

The total area of the compound shape is 36, therefore:

$3x^{2} -6x +x^{2} -4x=36$

$4x^{2} -10x-36=0$ (collecting like-terms and by bringing the +36 to the other side)

By dividing this by 2, you get:

$2(2x^{2} -5x-18)=0$

$2x^{2} -5x-18=0$

To find the length of AB (x), solve the quadratic by either factorising, completing the square or by using the quadratic formula, etc to solve for x.

$2x^{2} -5x-18=0$

$(2x-9)(x+2)=0$

$x=\frac{9}{2}$

$x=-2$

However, a length cannot be negative, so x must be $\frac{9}{2}$ or 4.5cm, so length AB = 4.5cm.

Hope this helps :)

Given that Begin equation 2/3A = 16, which of the following illustrates how the multiplicative inverse property can be used to f

tatiyna

2/3 A = 16

The multiplicative inverse is also known as the reciprocal. To solve for the value of A, multiplicative inverse is required.
The multiplicative inverse of 2/3 is 3/2. When you divide a number by a fraction, you first get the reciprocal of the fraction. Then, you multiply the number by the reciprocal of the fraction. 

2/3 A = 16
A = 16 / 2/3
A = 16 * 3/2
A = 48 / 2
A = 24

To check:
2/3 A = 16
2/3 (24) = 16
48 / 3 = 16
16 = 16
