Answer:

omgg i dont knowww

lets see if we take the square root of two then multiply it by five: its roughly 7.071

then after that we take the extra 0.071 and throw it in the trash

we next take 1+1+1 and subtract it from the extra seven we have left over

we end up with four.

maybe of course, this is an approximation

Fill in the table using this function rule y=27-4x

Elis [28]

Step 1: Y= 27 - 4x

To find X - intercept / zero, substitute Y = 0

0 = 27 - 4x

Step 2: 0 = 27 - 4x

Move variable to the left-hand side and change it's sign.

4x = 27

Step 3: 4x = 27

divide both sides of the equation by 4

X = 27/4

solution: X = 27/4

Alternate form: X = 6 3/4, X = 6.75

First observe that if $a+b>0$ ,

$(a + b)^2 = a^2 + 2ab + b^2 \\\\ \implies a + b = \sqrt{a^2 + 2ab + b^2} = \sqrt{a^2 + ab + b(a + b)} \\\\ \implies a + b = \sqrt{a^2 + ab + b \sqrt{a^2 + ab + b(a+b)}} \\\\ \implies a + b = \sqrt{a^2 + ab + b \sqrt{a^2 + ab + b \sqrt{a^2 + ab + b(a+b)}}} \\\\ \implies a + b = \sqrt{a^2 + ab + b \sqrt{a^2 + ab + b \sqrt{a^2 + ab + b \sqrt{\cdots}}}}$

Let $a=0$ and $b=x$ . It follows that

$a+b = x = \sqrt{x \sqrt{x \sqrt{x \sqrt{\cdots}}}}$

Now let $b=1$ , so $a^2+a=4x$ . Solving for $a$ ,

$a^2 + a - 4x = 0 \implies a = \dfrac{-1 + \sqrt{1+16x}}2$

which means

$a+b = \dfrac{1 + \sqrt{1+16x}}2 = \sqrt{4x + \sqrt{4x + \sqrt{4x + \sqrt{\cdots}}}}$

Now solve for $x$ .

$x = \dfrac{1 + \sqrt{1 + 16x}}2 \\\\ 2x = 1 + \sqrt{1 + 16x} \\\\ 2x - 1 = \sqrt{1 + 16x} \\\\ (2x-1)^2 = \left(\sqrt{1 + 16x}\right)^2$

(note that we assume $2x-1\ge0$ )

$4x^2 - 4x + 1 = 1 + 16x \\\\ 4x^2 - 20x = 0 \\\\ 4x (x - 5) = 0 \\\\ 4x = 0 \text{ or } x - 5 = 0 \\\\ \implies x = 0 \text{ or } \boxed{x = 5}$

(we omit $x=0$ since $2\cdot0-1=-1\ge0$ is not true)

Question 7 of 10

Gelneren [198K]

The group of values plugged into the TVM Solver of a graphing calculator that will return the amount of a 25-year loan with an APR of 16.8%, that is paid off with monthly payments of $340 is:

A. N=300; 1%-1.4; PV = PMT=-340; FV=0; P/Y=12; C/Y=12;PMT:END

What is monthly compounding?

Monthly compounding in this case the number of payments would be the number of monthly payments in 25 years, which is 300 monthly payments(i.e. 12*25=300), this means that options B and D are obviously incorrect because number of payments, N is given as 25( 25 years instead of 300 months)

What is monthly interest rate?

The monthly interest is the annual interest rate of 16.8% divided by 12, which is 1.40%, in short, option C is also wrong because I/Y(monthly interest rate) was as shown as an interest rate of 16.8% instead of 1.40%

Overall, the correct option is A, because the number of payments and interest rate were stated correctly, unlike other options that were incorrectly written
