Step-by-step explanation:
the area of the half-circle:
πr² /2= 3.14* 20² /2= 3.14 * 400 /2 =1256/2=628cm²
50*80/2=2000cm²
Shaded area:
2000-628=1372cm²
Amortization Solution:
A= P[[r(1+r)^n]/[((1+r)^n)-1)]]
P= $175,000
r= .06/12; divide interest rate by 12 to get monthly interest of 0.005
n=15*12=180; multiply by 12 to get the total number of payments
A= $87500 is the total cost of principal with interest rate of 0.5% monthly
Answer : A {-8}
-4 = b/2
-4 *2 = b
-8 = b
Answer:
26.83
Step-by-step explanation:
The missing leg is the square root of 29^2 - 11^2, which is 26.83.
Y = -5x + 9
y = 5x + 7
5x + 7 = -5x + 9
5x + 5x = 9 - 7
10x = 2
x = 2/10 reduces to 1/5
y = 5x + 7
y = 5(1/5) + 7
y = 1 + 7
y = 8
solution is (1/5,8)
