Sin(12) ≈ 0.208

  cos(x) = 0.208
  cos(x) = sin(12)
cos(78) = sin(12)

  cos(12) ≈ 0.978
  cos(68) ≈ 0.375
cos(102) ≈ -0.208
  cos(78) ≈ 0.208

The answer is D.

If a=(-1, -3) and b=(11, -8) what is the length of ab?
professor190 [17]

Answer: D.  The length is 13 units.

Step-by-step explanation:

(-1, -3 )    Find the difference between the x values and y values.

 (11, -8)  

-3-(-8) = 5

-1-11 =   -12    now find the  absolute values.

The absolute value of 5 is 5 .  The absolute value of  -12 is 12.

Now use the Pythagorean Theorem formula a^2 + b^2 =c^2  where c square is the length between AB.

5^2 + 13^2 = C^2

25 + 144 = c^2  

169=c^2

c= 13

Suzanne is looking at taking out a personal loan. Opportunity Loans is offering her $1600 at 3.45% for 1 year, with interest com
AleksAgata [21]

Step-by-step explanation:

So the general formula for compound interest is A = P(1+\frac{r}{n})^{nt} where r is the interest rate, t is the time in years, and n is the amount of compounds per year. So plugging in the values for both equations you'll get

Opportunity Loans:

 A = 1600(1+\frac{0.0345}{12})^{(12)(1)}

 A = 1600(1.002875)^{12}

 A \approx 1600(1.035)

 A = \$1,656.08

  Now to find the interest accrued on this loan you simply subtract 1600 from the A or final amount

 Interest=1656.08-1600\\Interest=56.08

General Loans:

 A = 1600(1+\frac{0.042}{4})^{(4)(1)}

 A = 1600(1.0105)^4

 A \approx 1600(1.042)

 A = 1,668.27

 To find the interest we do the same thing we did in the previous problem

 interest = 1668.27-1600\\interest=68.27

Opportunity loans has the least amount of interest after a year
