Answer:
Step-by-step explanation:
the domain for (2x-1)/(x^2-7) is x not equal to +/- sqrt(7)
Answer:
k = -3636
Step-by-step explanation:
you subtract 425 from both sides, it cancels out on the left and adds more to the right
Principal Amount = P = $885
Amount Accumulated = A = $3500
Interest rate = r = 12% = 0.12
Compounding period in a year = n = 2
Time in years = t = ?
The formula for compounding is:
Using the values, we get:
This means, it will take him 11.8 or approximately 12 years
Answer:
x = 125°
Step-by-step explanation:
There are 7 angles in this shape. The sum of the angles in a shape like this is calculated using a formula.
Total of angles
= (n - 2)•180°
Put in 7, because there are 7 angles.
= (7 - 2)•180°
= 5•180°
= 900°
So the total of the angles should be 900°. We know all of the angles except one.
900° = 123°+129°+128°+128°+132°+135°+ x
900° = 775° + x
Subtract 775.
125° = x
The missing angle is 125°.
