Answer: all real numbers
Step-by-step explanation:
7a + 1 = 8a - a + 1
7a + 1 = 7a + 1
a = all real numbers
Answer:
19/4
Step-by-step explanation:
0.5=12/10a-5.2
1/2=6/5a-26/5
5=12a-52
-12a=-57
Answer:
so you use the formula:
A = P(1 + r/n)nt
Where:
A = Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
R = Annual Nominal Interest Rate in percent
r = Annual Nominal Interest Rate as a decimal
r = R/100
t = Time Involved in years, 0.5 years is calculated as 6 months, etc.
n = number of compounding periods per unit t; at the END of each period
and you will get:
A = $ 4,432.85
A = P + I where
P (principal) = $ 3,600.00
I (interest) = $ 832.85
Answer:
As radius is perpendicular to tangent,
By pythagoras theorem :
x² = (x + 9)² - 15²
x² = x² + 18x + 81 - 225
18x = 207
x = 11.5
