Step-by-step explanation:
36/60 = 0.6
6/10=0.6
Answer:
x = 15
Step-by-step explanation:
Assuming 3x and x-60 are in degrees, you can use:
cos(a) = sin(a+90)
To rewrite the equation as:
sin(3x) = sin(x-60+90)
sin(3x) = sin(x+30)
3x = x+30
2x = 30
x = 15
But, solving 3x = x+30 which simplifies to x=15 is not the only solution to this equation, as you can see in below picture. Finding all solutions is a bit more work, but maybe that is not required in your case.
No x does NOT equal 16. you would substitute x for 16 which gives you 16+12. That equals 28 not 30. The correct answer is x=18
The square of 12 is 144 and the square of 13 is 169. Since 150 is in between those, it is C.
Hope this helps!
The monthly deposit should be $81.38.
An ordinary annuity is a fixed payment made for a fixed amount of time at the end of each period.
The formula to determine the monthly deposit is:
Future value / annuity factor
Annuity factor = {[(1+r)^n] - 1} / r
Where:
- r = interest rate = 5.5 / 12 = 0.4583%
- n = 20 x 12 = 240
35,450 / [(1.004583)^240 - 1] / 0.004583 = $81.38
