Answer:

-17√2 /26 or -0.9247 to the nearest ten thousandth.

Step-by-step explanation:

The hypotenuse of the right triangle in which tan x = 2/3 is √(2^2 + 3^2)

= √13 so sin x = 2/√13 and cos x = 3/√13

sin2x = 2sinxcos

= 2* 2/√13 * 3/√13

= 12/13.

cos2x = cos^2x - sin^2x

= 9/13 - 4/13

= 5/13.

sin(2x + 5π/4)

= sin2x cos5π/4 + cos2x sin5π/4

= 12/13 * -1/√2 + 5/13 * -1/√2

= -12 / 13√2  - 5 / 13√2

= -17/13√2

= -17√2 /26.

Cynthia had a credit card with a 17% APR and a $3,265 balance. She had budgeted to have the credit card paid off in 24 months. B
monitta

Answer:

Cynthia will have to pay $152.16 extra in finance charges.

Step-by-step explanation:

Cynthia had a credit card with a 17% APR and a $3,265 balance.

Cynthia’s credit card company has increased her interest rate to 21%.

Here we have two scenarios, 1st when p = 3265 r = 17% and n = 24

Second when p = p = 3265 r = 21% and n = 24

Scenario 1:

r =17/12/100=0.014166

EMI formula is :

\frac{p\times r\times(1+r)^{n}}{(1+r)^{n}-1}

Putting the values in formula we get;

\frac{3265\times0.014166\times(1+0.014166)^{24}}{(1+0.014166)^{24}-1}

= \frac{3265\times0.014166\times(1.014166)^{24}}{(1.014166)^{24}-1}

EMI = $161.43

Scenario 2:

r = 21/12/100=0.0175

Putting the values in formula we get;

\frac{3265\times0.0175\times(1+0.0175)^{24}}{(1+0.0175)^{24}-1}

= \frac{3265\times0.0175\times(1.0175)^{24}}{(1.0175)^{24}-1}

EMI = $167.77

Now, difference in EMI's = 167.77-161.43=6.34 dollars

And for 24 months this amount becomes = 24\times6.34=152.16 dollars

Therefore, Cynthia will have to pay $152.16 extra in finance charges.

Write an equation based on the word problem below and solve it. *
valkas [14]

Answer:

m = $12 per week

Step-by-step explanation:

The equation would be 8m + $150 = $246. To find out how much money you earn a week, you need to solve for m.

First, subtract $150 from both sides of the equation. Doing so will leave you with an equation of 8m = $96.

Next, divide both sides by 8. This will leave you with m = $12, which is your final answer of how much money you earn a week.
